Infrastructure Software Engineer

Job summary

Responsibilities

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.

• Design and build the platforms that sit between our engineers and the outside world: multi-tenant services that give dozens of teams isolated capacity, routing, quotas, and…
• Build the internal platforms and solutions that product and research engineers rely on every day, from deploy tooling to on-call automation, and treat them with the same design…
• Scale our multi-tenant services that fronts every model provider we use, so dozens of internal teams and products get isolated quotas, routing, observability, and capacity on…
• Run Temporal, Postgres, MongoDB, and our Kubernetes fleet at a scale where "it worked last month" isn't a guarantee, and design for the next 10x.
• Own the reliability program: define SLOs that matter, kill noisy alerts, make CI/CD deploys boring, and turn every incident into a durable fix rather than a runbook entry.

What they're looking for

• Bachelor’s Degree in Computer Science or a related technical degree such as Electrical Engineering, Physics, Mathematics, Computer Engineering, Information Systems or Statistics
• 2+ years of relevant industry experience
• 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.

Tech stack

• PostgreSQL
• Kubernetes
• Python
• Go
• AWS
• Terraform
