Remote AI Engineer

Job Description

Senior AI Engineer New York (Hybrid)

A recently minted unicorn — valued at $1.5B and backed by top-tier growth investors — is building the AI infrastructure that powers human-led creator commerce at scale.

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.

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 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

Strong TypeScript, Node.js, and relational database fundamentals
~ Real experience building systems that 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

Bonus Points
You’ve shipped agent systems, worked with frameworks like LangGraph or the Claude Agent SDK, written MCP servers, or built eval harnesses
S. citizen or green card holder (this company cannot sponsor visas).
