What this role actually is This is not “market research.” No 60‑page decks. No generic “digital health is big” observations. This is a continuous loop: market → signal → implication → decision → shipped product. Your job is to keep Terra’s roadmap and GTM pointed at the sharpest opportunities across AI × health, using: live conversations with users and near‑users, Terra’s own data and product surfaces, and the messy, high‑resolution context everyone else ignores. What you’ll do You will: Obsess over the people building on health data and AI Talk to founders, PMs, engineers, ops people, and researchers building on top of wearables, labs, and longitudinal health data. Extract what they’re actually trying to achieve, where they’re stuck, and what they’d pay for if it existed. Turn chaos into sharp segments Break the world into concrete, actionable segments like “AI assistants for metabolic health decisions” or “B2B platforms embedding Terra‑like health memory.” For each one: what they need from Terra, how big it is, and how fast we can move. Spot early product patterns from Terra’s own signals Read our usage, logs, support threads, builder questions, and integration patterns. Turn that into: “these are the workflows emerging on Terra; here’s the product that would make them 10x easier.” Live where our builders live Hang out in the places our users actually are: GitHub, AI forums, communities, niche health and bio circles, Telegram / Discord, X threads. Pull out early weirdness and translate it into “here’s a bet we should place.” Feed the team with decision‑grade direction For product: what to build, in what order, and which segments to explicitly ignore for now. For GTM: which users and use‑cases to prioritize this quarter, and what language will actually land. Ship clear, small artifacts Short memos, briefs, Looms-whatever works-as long as it’s clear. One screen, one idea, one decision. How you think You probably recognize yourself in most of this: You operate at street‑level resolution: real users, real tools, real workflows—not abstract “AI will change healthcare” slides. You like being early more than being universally agreed with. You’re comfortable saying “this is my best read with incomplete data, here’s the cost of being wrong.” You think in systems: products, data, incentives, distribution. You are allergic to analysis that doesn’t change what people do. You are AI‑native: you reach for Perplexity / GPT / agents the way others reach for spreadsheets. You instinctively ask “how would an AI use this data?” and “what does this unlock for ai?” when you see a new product idea. What we care about We don’t care about “years of experience.” We care about how you see and how you move. You might have: run product/market research or strategy at a startup, fund, or product org; built or worked around AI products, agents, or pipelines—and can show us your prompts, flows, or internal tools; done real work around health, data, or AI products (or can prove you climbed the curve fast); examples where your work directly changed a roadmap, pricing, positioning, or a go/no‑go decision. You definitely: move fast and don’t hide behind “we need more data”; can show written work that is brutally clear and directly actionable; are comfortable sitting close to founders and saying “I disagree, here’s why” when your read says so.

The Role You are the technical bridge between Terra's platform and our highest-value customers. You embed directly with their engineering and product teams to architect, integrate, and optimize their use of Terra's health data infrastructure. This is not support. This is not consulting. You are an engineer who ships — the difference is that what you ship lives inside the customer's stack, powered by ours. Day-to-day, you will: Design integration architectures for complex health data use cases — determining which Terra endpoints, webhook configurations, and data models map to the customer's product requirements. Write production code in the customer's environment: building webhook consumers, data transformation layers, authentication flows, and retry logic against Terra's API. Debug across the full stack — from a Garmin watch failing to sync, to a webhook payload arriving with unexpected schema, to a customer's data pipeline dropping events. Own the technical relationship with 3–5 strategic accounts simultaneously, serving as their dedicated Terra expert from pre-sales scoping through production go-live and beyond. Translate field learnings into product — when you see three customers struggling with the same edge case in sleep data normalization, you don't just fix it for them; you work with our engineering team to fix it in the platform. Build reference implementations, SDKs, and sample apps that make Terra's API easier for every developer, not just your accounts. Scope and qualify technical requirements during the sales cycle — determining whether a prospect's use case fits Terra's data model, estimating API call volumes, and defining integration timelines. What you'll work on These are real problems our customers bring to us. As an FDE at Terra, you'd own the technical delivery: AI & Personalized Health An AI lab wants to ingest continuous heart rate, HRV, sleep stages, and activity data from 200K+ users across multiple wearable brands through Terra's unified schema — to power real-time personalized wellness recommendations. You architect the data pipeline: webhook ingestion, event deduplication, backfill strategy for historical data, and rate limiting to stay within their processing capacity. A conversational health AI needs access to blood biomarkers (glucose, cortisol, cholesterol) alongside wearable data, all normalized and delivered via a single webhook. You design the integration that merges Terra's wearable and blood lab data streams into one coherent user profile. Insurance & Underwriting An insurer wants to use real-time biometric data (resting heart rate trends, VO2 max estimates, sleep consistency scores) to offer dynamic premium pricing. You scope the data sources, define the consent flow using Terra's authentication widget, and build the data delivery pipeline that feeds their actuarial models — while ensuring HIPAA and GDPR compliance. Clinical Research & Digital Health A clinical research platform needs longitudinal wearable data from a 10,000-participant study across Fitbit, Garmin, and Apple Health. Different devices report different metrics at different cadences. You configure Terra's integrations, build the normalization layer that maps device-specific quirks into a unified research dataset, and handle the edge cases: what happens when a participant switches devices mid-study, or when a data provider pushes a breaking API change. Fitness & Consumer Apps A fitness platform with 500K users wants to migrate from maintaining 15 separate wearable integrations to Terra's single API. You plan the migration: mapping their existing data models to Terra's schema, designing the cutover strategy, and building the webhook consumer that replaces their legacy polling architecture. Zero downtime. No data loss. Upstream Data Supplier Onboarding A wearable company wants to become a data supplier on Terra's platform — making their data available to Terra's downstream developer and AI ecosystem. You lead the technical onboard

we don't need a partnerships person. we need a dealmaker who happens to understand health data infrastructure. someone who can sit across from the CCO of a wearable company and speak product, then turn around and negotiate data rights, consent frameworks, and SLAs with their legal team the same afternoon. someone who has been in the room where a partnership got signed that changed a company's trajectory — and was the reason it got signed. the task you own the full pipeline — upstream and downstream. upstream is data suppliers. the wearable companies, the fitness platforms, the blood labs, the hospital systems, every new sensor company shipping hardware. you get them connected to Terra, negotiate the terms under which their data flows, and manage the relationship once they're live. downstream is the developers and AI labs consuming through our API. you land deals, expand usage, and make Terra the infrastructure they can't replace. you build and close enterprise-scale deals with companies that have hundreds of millions of users. you own the full cycle from first conversation to signed contract to live integration. these are complex, multi-stakeholder deals — product, legal, privacy, commercial, sometimes regulatory. you don't hand off to someone else to close. you close. you define the ecosystem strategy. which verticals — metabolic health, women's health, longevity, performance, clinical research, insurance, pharma? which geographies? which partner types unlock the most downstream value? you draw the map. then you execute against it. you negotiate data supplier agreements that actually hold up. data rights, consent frameworks, downstream access controls, AI use case permissions, exclusivity terms, SLAs, privacy compliance across GDPR, HIPAA, CCPA. every supplier is different. a fitness platform cares about different things than a blood lab. you need to understand both well enough to structure something that works for us, works for them, and stands up to legal scrutiny on both sides. you represent Terra in the rooms that matter — board rooms, conferences, partner offsites, podcasts. you are credible with the people running billion-dollar health businesses. not because you rehearsed talking points, but because you actually understand the health data ecosystem, the product, and the commercial dynamics at play. you build the function. playbooks, pipeline tracking, tooling, eventually a team. this is a build role. if you need a manager to tell you what to do next, this is the wrong place. who you are you've done deals that changed the trajectory of a business. not "managed a partner portfolio." closed something that moved a number the CEO cared about. if the biggest deal you've done is a co-marketing agreement, this isn't the right fit. you've operated in health, fitness, wearables, or health data. you know the ecosystem — who the players are, what motivates them, where the regulatory landmines sit, and why a wearable company might say no to a data partnership (and how to get them to yes). you don't need a primer on HIPAA or GDPR. you've lived it. you understand platform economics. you've worked at or sold into API-first companies, infrastructure businesses, or developer platforms. you know what it means to be the connective layer — where trust, reliability, and data quality are the product. you get why a developer's experience with your API matters more than your sales deck. you are comfortable in complexity. data rights across jurisdictions. consent models that vary by partner. AI use cases that some suppliers welcome and others won't touch. you can navigate all of it without defaulting to "let me check with legal." you think like a strategist and execute like an operator. you are not a conformist. you didn't follow the standard BD playbook. you invented your own. you built a commercial engine from scratch, or scaled a growth model nobody believed in, or launched a business line everyone told you was too early. you were contrarian

Terra is the connective tissue between the world's health data and the developers building on top of it. We ingest from 500+ upstream sources, normalize everything into a single schema, and deliver 8B+ events/year to 1,000+ developers and AI labs via webhooks, SQL, cloud storage, and queues. The platform is the product. We're building the upstream supplier connector — a new ingestion layer for data suppliers to push directly into Terra. AI labs are consuming at rates we didn't plan for. The pipe needs to get wider, faster, and more reliable. This role exists because the platform needs a dedicated owner. Someone who thinks end-to-end — from a Garmin syncing at 3am to a webhook landing 400ms later. You're not building features. You're building the foundation. What you'll own The full data path from source to destination. Ingestion Pipeline — How provider data enters Terra from cloud APIs (Garmin, Fitbit, Oura) and mobile SDKs (Apple Health, Health Connect). Raw data in, queued for normalization. Normalization Engine — Transforms heterogeneous provider payloads into Terra's standardized models: Activity, Sleep, Daily, Body, Menstruation, Nutrition. The core IP that makes 500+ sources feel like one. Event Delivery — Webhooks, Postgres/MySQL, Supabase, S3, SQS, Kafka. At-least-once delivery, ordering, retries, dead-letter queues. Data reaches destinations reliably. Provider Framework — How new Sources get onboarded. Web-based (OAuth, polling, rate limiting) and mobile-only (on-device SDK, background sync). Adding provider #501 should be as fast as #5. Auth & Connections — Connect widget, custom UI flows, OAuth sessions, Terra User lifecycle, Reference ID mapping. Upstream Supplier Connector — New ingestion surface. Data suppliers push into Terra instead of us pulling. Ground-up build. API Versioning — Backwards compatibility and deprecation across the /v2 surface. Observability — Monitoring and alerting across the full pipeline. You know when a provider degrades before our developers do. What you'll build Scale event delivery to 10x — AI lab consumption is growing exponentially. Redesign the hot path without proportional cost increase. Ship the upstream supplier connector — Schema contracts, auth, validation, rate limiting. The interface for suppliers to push directly into Terra. Redesign normalization for schema evolution — Providers change APIs. Our models evolve. Downstream consumers can't break. Multi-destination fan-out — One event, reliably delivered to webhooks, SQL, S3, and queues simultaneously. Independent retry logic per destination. Provider health dashboards — Real-time visibility into every Source's freshness, latency, error rates, and schema drift. Harden mobile SDK data path — Apple Health and Health Connect are fundamentally different from cloud APIs. On-device processing, background sync constraints, OS-level limits. Make it scale. Who you are A systems thinker — you see data flow and failure modes before you see features. Battle-tested at scale — you've operated platforms processing billions of events. You've fixed production at 2am. Observability-first — monitoring and tracing are part of your design, not bolted on after. Opinionated where it matters — event delivery guarantees, schema evolution, idempotency, API versioning. Opinions earned by shipping. Fast — architecture whiteboard Monday, production deploy Friday. Default yes — hard problems make you lean in. Accountable — you own production, you respond to incidents, you care about uptime. Skin in the game. <h3>Big Plus</h3> You are an athlete. You train, you compete, you push limits — or at the very least, you are obsessed with quantifying your own data. The discipline, ambition, and courage it takes to show up every day and get better is the same energy we run on. If you understand the data because you live it, you'll build a better product.

you know the feeling. you're scrolling, you stop, you watch, you send it to someone. that's not an accident. someone made that happen with a cut, a beat, a frame. that someone is who we're looking for. Terra is the health operating system. we connect 500+ wearables, sensors, blood labs, and health apps into a single API that powers 1,000+ developers and AI labs. we process 15B+ health data events per year. we've sat down with Lance Armstrong, Bryan Johnson, the co-founder of Strava, a Sequoia partner, and the CTOs behind 80M-user health apps — and recorded all of it. we have the raw material. hours and hours of founders, athletes, and scientists saying things that would stop a feed cold. what we don't have is someone who can turn that into the thing people can't scroll past. the work you take long-form content — podcast episodes, conference talks, interviews, demos — and turn it into short-form that spreads. not "clips." not "highlights." pieces that have a reason to exist on their own. the kind that make someone who's never heard of Terra want to know everything about us. you understand pacing. you know that a 90-second clip lives or dies in the first 1.5 seconds. you know when to cut tight and when to let a moment breathe. you know that a pause before a hard truth hits harder than a jump cut. you have an instinct for where the tension is in a conversation, and you build the edit around it. you own the visual language. subtitles, framing, color, motion — you make decisions about all of it. you're not waiting for a brand guide. you're creating the visual identity of how Terra shows up on feeds. LinkedIn, X, YouTube Shorts, TikTok, Instagram Reels — you understand that each platform has its own grammar and you edit accordingly. you think in distribution, not just production. you don't just ask "is this a good edit?" you ask "will this get shared?" you understand hooks, retention curves, and why some videos die at 3 seconds while others get watched twice. you've studied what works — not by reading blog posts about it, but by making things that worked. you create original content too. not just cuts from existing footage. you pitch concepts, storyboard ideas, and produce pieces from scratch when the moment calls for it. a 60-second brand film. a visual essay on why health data is broken. a montage that opens on a heartbeat and ends on a unified API. you think like a filmmaker, not a social media manager. you move fast. we don't have a 3-week review cycle. you edit, you ship, you watch the numbers, you learn, you do it again. the gap between idea and published is hours, not weeks. who you are you have a portfolio of work that stopped people mid-scroll. not corporate sizzle reels. actual short-form content that performed — views, shares, saves, comments. you can point to specific pieces and tell us why they worked. you understand health, fitness, and performance culture. not because you studied it — because you live in it. you know why a clip of someone talking about HRV at 3am after a hard training block hits differently than a generic wellness quote. you know the difference between longevity twitter and CrossFit instagram and you can speak to both. you have a contrarian eye. you don't copy what's trending. you look at what everyone else is doing and find the angle they missed. the best viral content doesn't follow the format — it breaks it just enough to feel fresh while still being legible. you are technically sharp. Premiere, Final Cut, DaVinci, After Effects, CapCut — whatever. the tool doesn't matter. what matters is you can take raw footage with bad audio and inconsistent framing and turn it into something that looks and sounds intentional. you are opinionated about content. you have strong views on what makes a good hook, what makes a good cut, what makes someone hit share. you argue for your edits. you don't just take notes and execute — you push back when the edit would be worse. big plus you are an athlete. you train, you
