Senior/Staff AI Engineer — Agentic Development (Next.js/Node.js)
Posted 22 days ago
Contract | 40–80 hrs/week
Roles open on a rolling basis - apply to join the talent bench and we’ll reach out when one matches. Expect 40+ hrs once a project starts; timing depends on availability, but we move people in at the earliest genuine opportunity.
We're looking for senior-to-staff+ software engineers to build in a fast-moving, high-ambiguity environment with tight deadlines and demanding KPIs. This is hands-on engineering work for people who know how to move quickly and operate with minimal direction.
What You'll Be Doing
You'll be building agentic applications and tooling at the frontier of LLM-powered development. This means working directly with modern coding agents and LLM infrastructure, shipping fast in an environment where requirements shift, and the bar is high. You'll need to make strong judgment calls under pressure and deliver without hand-holding.
Tech Stack
The core stack is Next.js/Node.js with TypeScript throughout — typed end-to-end, no exceptions. You should be deeply fluent in this ecosystem rather than just familiar with it.
Who You Are
You're a minimum senior-level engineer, though staff+ level is ideal. You have hands-on agentic development experience, including practical knowledge of LLMs and familiarity with the tooling ecosystem for coding agents. You thrive in highly ambiguous environments, work well under tight deadlines, and are comfortable being measured against very high KPIs. You move fast without sacrificing quality.
Nice to Have
RAG application development experience is a plus. A background in reinforcement learning (RL) is also valuable.
