Software Engineer (Infrastructure)

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.

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.

Deep expertise in Postgres at scale, including query optimization, indexing strategy, replication, and the failure modes you only learn the hard way.

Strong fluency with job queue infrastructure, AWS, OpenSearch, and Redis. You know where each one shines and where each one breaks.

A sharp instinct for tradeoffs. Infra projects can take months. The best infra engineers know how to ship the 80% solution that captures most of the value in a fraction of the time, and how to recognize when the 100% solution is actually worth it.

Excitement about the scaling problem in front of us. You should want to take a small startup's infrastructure and turn it into something that handles massive scale, and you should want to do it as the person making the calls, not as one engineer on a team of fifty.

Excellent written and verbal English communication. You can document an architecture decision in a doc another engineer can read in five minutes.

You want to work on infra at a company that already has it figured out. Centralize doesn't, and that's the point.

You prefer to specialize in one layer of the stack. Our infra engineer touches Postgres, queues, search, cache, AWS, and the integration layer.

You optimize for the perfect long-term solution at the expense of shipping. Infra at Centralize is graded on impact per week, not architectural elegance.

You want a slower pace. We work hard and move quickly. Please only apply if that excites you.

You'll work directly with Rachit and Will, alongside former founders and engineers from Coinbase, Gusto, Modern Treasury, and C3 AI.
