Senior Software Engineer, Agent Platform
New York, NY
Is your CV ready If so, and you are confident this is the role for you, make sure to apply asap.
A recently-minted unicorn — valued at $1.5B and backed by top-tier growth investors — is building the AI infrastructure powering human-led creator commerce at scale, helping brands run performance-driven creator programs with the world’s top creators.
About the Role
This is a rare shot at building an AI infrastructure layer from the ground up — not a chatbot wrapper, but a full agent orchestration platform every internal AI agent runs on. You’ll join a small, elite team defining how autonomous agents get built, evaluated, and trusted in production, inventing the abstractions the company’s AI strategy will run on for years.
What You’ll Do
- Architect the orchestration core powering autonomous, multi-step AI agents — triggers, durable workflows, and runs that can pause and resume around human judgment
- Build the tool layer that gives agents real-world capability: live integrations with Slack, Linear, GitHub, Notion, and MCP, plus a dynamic tool registry
- Build the console agent managers use to create, evaluate, and iterate on agents in real time (React)
- Solve the hard, mostly-unsolved problem of making nondeterministic AI behavior legible — run tracing, evals, feedback loops, cost attribution
- Design and ship APIs in TypeScript/NestJS on Postgres, deployed on AWS
You’re Energized By
- Working at the frontier — durable execution, human-in-the-loop, memory, and evals for nondeterministic AI systems are problems you’ll help define, not inherit
- Platform engineering with your users in the building: feedback on your AI infrastructure arrives in hours, not quarters
- Finding the elegant abstraction that turns a one-off agent into a repeatable capability
- Being early enough that your technical calls become the company’s AI architecture
What We’re Looking For
- Strong TypeScript, Node. xhuatnn js, and relational database fundamentals
- Real experience building systems other engineers build on — internal platforms, frameworks, orchestration or developer tooling
- Genuine hands-on AI/agent experience: tool calling, context and memory design, evaluating nondeterministic behavior
- Experience deploying and operating production services on AWS
- AI-assisted development (Claude Code, Cursor, or similar) as a core part of how you already work
- 5+ years of professional software engineering experience
