Software Engineer (Infrastructure)

About Centralize

Enterprise sales runs on relationships, and every tool built to manage them is a database from 2005. Reps lose seven-figure deals because they can't see who actually matters inside an account. We're building the system of intelligence that replaces the CRM.

Centralize is the relationship intelligence platform for enterprise revenue teams. Webflow, Intercom, Brex, Cognition, LangChain, and Cresta use us to close their largest deals. We've grown 5x since last year, and customers are pulling us forward faster than we can ship.

We just raised a Series A led by NEA, bringing our total funding to $17M+ alongside Salesforce Ventures, Y Combinator, and operators including Cal Henderson (Co-Founder, Slack), Noah Weiss (former CPO, Slack), and sales leaders from Figma, Box, Dropbox, Anthropic, and Notion.

Centralize was founded by Rachit Kataria, a founding engineer on Facebook Shops who helped scale it to 250M MAUs, and Will Wang, who led the launch of Slack Huddles, the fastest-growing product in Slack's history.

Our Bar

We stay small on purpose. No passengers, no politics, no waiting for permission or for someone else to fix what's broken.

We own the unglamorous work alongside the exciting work. The 9pm customer request, the integration buried three layers deep, the bug nobody wants to touch. You go after it because it needs to get done, and because the next thing you build is better for it.

You won't have the answers handed to you. The roadmap, the architecture, the right call on a customer request, you'll be the one figuring it out. We hire people who are energized by ambiguity, not slowed down by it.

Your work shapes what Centralize becomes.

The Role

We are hiring an infrastructure engineer to own scalability across Centralize. Our system processes millions of events per day from integrations across our customers' tech stacks and writes hundreds of millions of records into our pipeline. The infrastructure that makes that possible is yours to design, harden, and scale.

You'll own Postgres, our job queue infrastructure, our backend architecture, and the systems that move data from customer integrations into the product. You'll work in AWS, OpenSearch, and Redis, and you'll be the person who decides how we scale from tens of thousands of concurrent jobs to whatever comes next.

This role is well-suited to engineers who have already scaled fast-growing systems through their hardest growth phases and want to do it again, this time with full ownership and a small team that ships quickly.

What You Will Do

Own the architecture and scalability of our backend systems, including Postgres, job queues, OpenSearch, Redis, and the data pipelines that move events between customer integrations and our product.

Scale our infrastructure from tens of thousands of jobs to orders of magnitude more, ahead of customer demand rather than behind it.

Make the tradeoffs that determine whether infra work takes weeks or months. We need someone who knows when to ship the duct-tape fix that buys six months and when to invest in the rewrite that buys five years.

Set the bar for reliability, observability, and operational excellence. You decide what "production-ready" means at Centralize.

Partner with Will on architecture decisions and with product engineers on the systems they build on top of yours.

What Success Looks Like

Day 30: First major scalability win shipped, with measurable impact on throughput, latency, or cost.

Day 60: Owning the on-call rotation, observability stack, and capacity planning for our core systems.

Day 180: Our infrastructure handles 10x the load it does today, and you're already planning for the next 10x.

What We Are Looking For

Demonstrated experience owning and scaling fast-growing production systems that process millions of events per day and hundreds of millions of writes. We need someone who has lived through the hard growth phases, not someone who has read about them.
