This is a staff-level IC role for someone who thrives in ambiguity, moves fast, and raises the bar for everyone around them. You’ll work across systems, infrastructure, and product surfaces — partnering closely with engineering, product, and leadership to scale what’s already working and build what’s next. This is not a “ticket taker” role. You’ll define problems, design solutions, and ship. KEY RESPONSIBILITIES Own the design and evolution of core platform and systems architecture.

Direct influence on product and company direction. A small, high-caliber team with very little process drag. Problems that matter — to customers, revenue, and scale.

You can learn complex topics (AI, telephony, APIs) and explain them simply. Bonus: you have technical skills or experience writing for dev audiences. PORTFOLIO ASK When applying, please include a portfolio. Specifically, we’d love to see a before-and-after example : a technical changelog, release note, or product update that you turned into a polished, world-class announcement. Include the original raw input and the final version you shipped. Tell us the customer value behind it — why should anyone care?

What Retell does Retell is the voice AI platform for production phone agents. Enterprise call centers use us to deploy AI agents that handle real calls — inbound and outbound — at scale. 50M+ conversations/month. YC-backed. ~20 people. What this role is You make Retell's community into a growth channel. Here's what that means concretely. We already have the scaffolding: a Certified Partner Program with tiers, a growing roster of agency partners, an app partner directory, a Discourse forum, and YouTube creators making Retell content organically. What we don't have is someone who owns all of it full-time and turns it into a compounding growth engine. What you'll do Scale the partner ecosystem. We have certified partners building voice agents for clients across healthcare, restaurants, real estate, insurance, and more. You'll be the person who activates this ecosystem — recruiting new partners, keeping existing ones engaged, making sure they have what they need (early access, co-marketing, referral tracking, templates), and tracking which partners are actually driving revenue. The goal is to make "build it on Retell" the default choice for every AI agency and consultant in the voice space. Build the creator and content flywheel. Retell tutorials are already showing up on YouTube organically. Your job is to accelerate that — find the creators, give them a reason to keep producing (affiliate structure, featured placement, verified status, early access), and build the pipeline so we're getting a steady stream of third-party content every month. Not by writing it yourself. By making it worthwhile for others to create. Own community infrastructure. Take over Discourse. Fix the support experience. Build the culture where builders help each other. Run regular community touchpoints — hangouts, builder spotlights, newsletters, contributor recognition. Make it the place people come to learn how to build voice agents, not just to file support tickets. Drive community-sourced SEO. Every partner case study, every creator tutorial, every forum thread answering "how do I build an AI phone agent for X" is a long-tail landing page. You should be thinking about how every community action you enable creates organic discovery. What makes someone great at this You've taken an early-stage partner or creator program and scaled it — not just launched one, but made it produce measurable output over time You've worked with technical creators and know what it takes to get someone to choose your platform as the subject of their next video or tutorial You understand affiliate and referral economics. You can design incentive structures and tell which relationships are worth doubling down on You've run a technical community (Discourse, forum, Slack) past the phase where the company is answering every question You get SEO at a practical level — community content that ranks Bonus: you've been inside a PLG ecosystem (automation tools, developer platforms, no-code/AI tools) and know how these flywheels work from the operator side

We'll give you the roadmap, not a daily standup. Details: • Contract, remote • Flexible hours based on content pipeline • Start ASAP To apply: Send 2-3 examples of SaaS tutorials you've created (video or written) + a short note on how you'd explain a voice AI integration to a non-technical audience.

We want someone who can write, ship, measure, and iterate fast. What You'll Do Own and grow Retell's organic search channel end-to-end, including technical SEO, content strategy, and AI answer engine optimization (AEO). Set keyword and topical authority strategy across our core verticals: voice AI, call center automation, AI agents, and industry-specific terms.

About Retell AI Retell AI is a Y Combinator-backed voice AI platform that powers AI phone agents for enterprise call centers. We're at ~$36M ARR with a team of ~20. Our customers replace legacy IVR systems and human agents with conversational AI that actually sounds human. We sell to call centers with 100+ agents. Our buyers are VP of Operations, CX leaders, and contact center directors at companies like insurance carriers, healthcare orgs, financial services firms, and BPOs. The Role We don't need another SDR who sends 500 emails a week. We need someone who treats outbound like a lab. You'll own the full experimentation cycle for creative prospecting — designing new outreach plays, running them, measuring results, and scaling what works. You report directly to the CEO. This is not a "set up sequences in Outreach and optimize subject lines" role. Here's a sample of experiments on our roadmap: IVR teardowns: Call a prospect's 1-800 number, record the experience, build a side-by-side with what Retell sounds like, and send it to their VP of CX Permissionless pilots: Build a working demo of a prospect's use case before they ask for one, and send it cold Physical gifting: Send cookies, handwritten notes, or a relevant book with a sticky note to decision-makers who won't respond to digital LinkedIn voice messages: Record personalized 60-second voice notes to prospects Community infiltration: Find where call center ops people hang out (Slack groups, Reddit, CX forums) and become a trusted voice before ever pitching Champion-building from below: Reach agent supervisors who feel the pain daily, arm them with materials to push the conversation up VidYard walkthroughs: Record a personalized video showing the prospect's exact use case on the Retell platform, including how the AI voice sounds on a real call Warm path engineering: Map mutual connections, YC network ties, and board-level relationships to broker warm intros Signal-based triggers: Monitor job postings, tech stack changes, funding rounds, and earnings call language to time outreach perfectly MS Teams / Slack Connect messages: Find and reach people on platforms they actually check You'll also own the tracking infrastructure — what experiment ran, to whom, what happened, and what we learned. We want a system, not a spreadsheet of hunches. What We're Looking For Must-haves: You've done outbound before and know what "normal" looks like — so you can go beyond it You think in experiments: hypothesis → test → measure → iterate You can write. Your emails, notes, and scripts need to sound like a human who did their homework, not a template You're resourceful and scrappy — you'll figure out how to get handwritten notes sent, how to find someone's direct line, how to get into a niche Slack group You can self-manage. We'll set goals together but you run your own calendar Strong signals: You've used tools like Clay, Apollo, LinkedIn Sales Nav, Sendoso, Vidyard, BuiltWith, or similar — but more importantly, you've stitched tools together into workflows that actually produced pipeline You've worked at a startup where outbound was the primary growth lever You've sold or prospected into call centers, BPOs, or enterprise CX teams You've done something creative in outbound that actually worked and can tell us the story Not looking for: Someone who only knows email sequences and cold calling Someone who needs a playbook handed to them Someone uncomfortable with ambiguity or running plays that might not work How This Works Start as a contract (30-40 hrs/week). If it's working, we convert to full-time. You'll work directly with the CEO and our outbound SDR. First 2 weeks: audit our current outbound, pick 3 experiments, and run them. We evaluate based on experiments launched, quality of execution, and pipeline generated. To Apply Skip the generic cover letter. Instead, tell us: One creative outbound play you've run that actually generated meetings or pipeline. What was it, why did it work,

ABOUT RETELL AI Retell AI is using the first principles to reimagine the call center with cutting edge voice AI. Since launching 18 months ago, thousands of companies now utilize Retell’s AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by Y Combinator, Alt Capital, and other leading investors, we have scaled to $36M ARR with a team of 20 people, up from $5M at the start of 2025. Our vision for 2026 is to build a modern CX platform where entire contact centers are powered by AI. Instead of basic automation that needs constant human tuning, we’re creating intelligent AI “workers” that can act as frontline agents, QA analysts, and managers — continuously executing, monitoring, and improving customer interactions.

Manage cloud deployments across AWS/Azure/GCP and coordinate with on-prem infrastructure teams; standardize with IaC (e.g., Terraform). Implement robust observability (metrics, logs, traces), SLOs/error budgets, and automated rollback/one-click restore. Partner with compliance to integrate SOC 2 / ISO 27001 / HIPAA controls into pipelines (artifact signing, SBOMs, change management, access/keys). Deploy at customer sites (cloud or on-prem), collaborating with client teams for integration, runbooks, and handover. Lead incident response & postmortems; drive resilience, cost, and performance improvements. Document release processes and platform conventions; codify best practices into tooling and templates. YOU MIGHT THRIVE IF Have 3+ years of deep experience with a major cloud (AWS, Azure, or GCP) and container orchestration (Kubernetes, Helm). Build production-grade CI/CD with GitHub Actions / GitLab CI / Jenkins (or similar), including complex rollout strategies. Have shipped both SaaS and on-prem solutions, navigating networking, security, and environment drift. Can integrate compliance and security into delivery (secret management, image signing, policy-as-code). Are comfortable with networking fundamentals, security hardening, and performance tuning. Communicate clearly, move fast in ambiguity, and enjoy being the responsible adult in prod.
