Senior Agent Engineer at Mercor
posted 5 months agoSenior Agent Engineer | $500/hr | Worldwide Remote
Mercor is seeking experienced engineers who have shipped production AI agents to join a high-impact, remote engagement. If you've built orchestration frameworks, eval harnesses, tool-use runtimes, multi-step workflows, or retrieval systems that agents call into — we want to hear from you.
What to Expect
- An async AI screening (~20 minutes) covering agent architectures, eval practices, and a walkthrough of recent work
- A live follow-up session for top candidates
Ideal Background
Any one of the following qualifications is sufficient:
- Individual contributor who built an in-house agent framework or cloud-agents runtime
- Experience building eval infrastructure for agents — offline and online, regression detection, cost/latency SLOs
- Hands-on work with tool-use, MCP, or orchestration layers
- Experience with memory, retrieval, or state-passing primitives for agents
Engagement Details
- Format: Fully remote, one-time commitment
- Rate: $500/hr — reflecting senior-to-staff engineering compensation bands
- Scope: Both frontier-lab and applied-product backgrounds are welcome
This is an opportunity to work at the cutting edge of AI agent development with a team that values deep technical expertise and real production experience.
