About the role

Platform and infrastructure engineering role focused on building, operating, and scaling Mercor Enterprise Platform across hosted and customer environments. Pure platform work with close collaboration to Applied AI engineers, aimed at delivering enterprise-grade security, isolation, and efficient agent execution.

Responsibilities

  • Design, build, and operate the services the platform is made of: authn and authz, credential brokering, routing, sandboxing, and orchestration.
  • Design the interfaces other engineers build agents against, and keep the paved path the easiest one to follow.
  • Build the event-driven backbone so that ingestion stays idempotent when services scale horizontally.
  • Own the deployment model itself, from hosted offering to customer VPCs and multi-cloud, so a new deployment needs no bespoke build.
  • Keep tenants isolated by construction, so one run cannot reach or spend beyond its own quota.
  • Own latency, throughput, and cost per run as volume grows, along with production debugging that comes with them.
  • Set the direction for the parts of the platform you own, not just the implementation.
  • Partner closely with Applied AI engineers on the hardest problems coming out of deployments. They own the customer relationship, you own the platform.

Qualifications

  • Bachelor’s Degree in Computer Science or a related technical degree such as Electrical Engineering, Physics, Mathematics, Computer Engineering, Information Systems or Statistics
  • 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.
