Mercor is organizing human intelligence to power the AI economy. We are powering frontier research, AI benchmarks, and AI agent training at scale for the top AI labs and enterprises. Backed by General Catalyst and Menlo.
About the role
The Mercor Enterprise Platform is what enterprise customers and our Applied AI engineers use to build and run complex agents. It is both deployed into customer environments and hosted by us. It is also the central platform for every internal agent at Mercor, scaling to several thousand agent runs per day, and still growing.
What they're looking for
- 5+ years of experience building high scale, complex software systems
- You have built and operated a platform other engineers depended on, and owned the architectural calls on it rather than only the implementation
- Hands-on with several of these primitives: authn and authz, secrets, isolation, orchestration, egress, and durable state, in more than one cloud
- A drive to keep making systems faster and cheaper after they already work
- Demonstrated ability to work independently on ambiguous, loosely specified problems
- Bonus: experience with LLM applications, agent frameworks or harnesses, evals, or deployed software
