## About the role

Build agentic infrastructure. Our agents don’t answer a question and disappear. They take on units of work that run for hours or days, change hands, and keep driving toward completion. You’ll build the runtime that creates continuity for that work: long-running sessions that survive failures, durable workflow state, lifecycle and cancellation, and workflows that track each piece of work across every stage and every party involved. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- A builder mindset. You own projects end to end, think carefully about data models, performance, and maintainability, and have taken prototypes to production with a clear sense of the reliability and scale tradeoffs
- 3–5+ years building backend systems, ideally real-time, stateful, or event-driven workloads, with strong distributed systems fundamentals: message queues (Pulsar, Kafka), distributed locks, pub/sub, and their failure modes
- Experience building infrastructure for LLMs in production: tool calling, streaming, token budgets, or evaluation harnesses, and a sense of what agents need from the systems beneath them
- You keep work moving. You balance speed of execution with code quality, unblock yourself when you can, and pull in the right people at the right time when you can’t
