About us
We're a small, talent-dense, YC-backed team building a new kind of AI-native workspace. Our platform lets knowledge workers orchestrate hundreds of thousands of agents in one click, compressing days of research into seconds. Our investors and advisors include founders of some of the best-known developer-tools companies.
The problem
Our infrastructure processes millions of tokens per minute across 100,000+ parallel agents. You'll work on problems that only show up at this scale:
Preventing race conditions when 10^5 agents write to a shared data model at once
Streaming agent outputs in real time across every service to the client
Optimizing write throughput and in-memory footprint per agent
You'll own large pieces of the product end to end, from design through production, and help define how knowledge workers use AI.
What you'll do
Design, build, and ship backend and distributed-systems code that powers the core product
Take a whole project as the primary IC and drive it to production
Work across the stack, with a backend and distributed-systems lean
Be the go-to person for debugging hard problems
Explain complex concepts clearly and help the team align on hard decisions
What we're looking for
5+ years as a software engineer
A record as the primary IC on several medium to large projects
Production experience designing, deploying, and managing distributed services (go,C++, or similar)
Visible technical depth, such as custom indexing, concurrency, or low-level systems work, not just business impact
A hands-on builder profile, with a strong, upward career trajectory at top-tier engineering teams or high-growth startups
Seen by peers as a resource for debugging and answering questions
Bonus points
Big tech followed by high-growth startup experience
Experience with Go, Redis, PubSub, RPC, Postgres, S3, or Temporal
Product-led work, strong competitive programming results, or original code you can show
Benefits
Health insurance, 401(k), PTO, meaningful equity, and a high-ownership, in-person team.

Skills
C++, PostgreSQL, Redis

Experience
5+ yrs
