About the role
About Proliferate
Proliferate is the open, harness-agnostic platform for running coding agents- Claude Code, Codex, Gemini CLI, whatever comes next- in parallel, locally and in the cloud. We think the next decade of software gets built by engineers directing fleets of agents, and that layer shouldn't belong to any one model vendor. We're building it.
We're backed by True Ventures, Pear VC, and 50+ YC founders, with plenty of money to keep building through rough patches. We work in person in SoMa, San Francisco.
About me, the founder
I'm Pablo. I finished my master's in AI at 19, joined Onyx (YC W24) as engineer #1, spent a year building enterprise AI search, then started Proliferate. You'd be hire #1- we'd work side by side every day, and there is a lot of room to grow.
How we work
- We ship unusually fast
- Tiny team, absurd ownership: you will build core pieces of product end to end.
- We take health extremely seriously: company-expensed Whoop, wellness stipend, all meals covered, top-tier insurance- and a culture that treats sleep, training, and building a good life as tenets of a good company culture.
Example work
- Build a new core workflow end to end across agent runtime, product UI, and cloud infrastructure.
- Design a new interface for human-agent collaboration made possible by a model capability that landed last week (or earlier today).
- Turn a rough customer pain point into a polished product surface in days.
- Re-think how engineering teams review, redirect, and trust agent work before merge.
You might be a great fit if
- You've shipped products 0→1 and have strong opinions about software
- You use AI tools conscientiously- and have real takes about where they fail
