About the Role
Every time someone talks to Flow, they're waiting — mid-sentence, cursor blinking — for their words to appear. 500ms feels like magic. 1000ms feels annoying. People use Flow hundreds of times a day, and they feel every single request. We've scaled our user base faster than our infrastructure could keep up with. We build and deploy our own voice models, and we've tuned our networking stack to hit P50 latencies of 500ms around the globe. We're shipping new surfaces fast, which means the core platform now needs far more rigor and a lot more headroom. We've built for millions of users and thousands of enterprises with a three-person platform team. You'd be on the ground floor, creating the systems that support the next hundred million.
Responsibilities
- Build the seam between product and ML: credentials, proxy, routing, experimentation.
- See the next scaling bottleneck two quarters early and fix it before anyone notices it existed.
- Architect and own whole parts of the platform end to end.
- Make every product engineer faster — dev experience, deploy speed, abstractions.
- Help set technical direction as the team goes from three to eight.
Requirements
- You've rewritten an entire service because you realized the bugs were all coming from bad architecture.
- You've seen systems break, understood why, and now think twelve months ahead.
- You build the foundation patiently so that everything after it ships faster.
- You get excited about complex problems with lots of constraints and edge cases.
- You care as much about the user journey as the technical requirements.
