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
As an Infrastructure Engineer at Mercor, you’ll build and scale the systems that power our rapid growth. You’ll ensure our infrastructure is highly available, cost-effective, and able to handle explosive traffic and compute demands. You’ll work closely with engineers across product, research, and operations to design scalable architectures, streamline deployments, and improve observability.
What they're looking for
- We care far more about how you reason about systems than which tools you've used. Strong candidates typically have:
- A deep grasp of reliability and scalability fundamentals: failure modes, backpressure, idempotency, capacity planning, and how distributed systems actually break under load
- Experience operating production systems that real users depend on, and the scars to prove it
- Comfort writing code in a language like Python or Go, and reading code in whatever the incident requires
- Familiarity with cloud infrastructure (we're on AWS) and infrastructure-as-code (we use Terraform). You don't need to be an expert, you need to be curious and fast to pick it up
- Working knowledge of containers and how they're deployed. Kubernetes experience is a plus, not a gate
