About the Role

The Mercor Enterprise Platform is used by enterprise customers and Applied AI engineers to build and run complex agents. It is deployed into customer environments and hosted by Mercor. This role is a pure platform and infrastructure engineering position, focusing on enterprise-grade security, routing, isolated execution, and the intelligence plane that improves production runs. You will work closely with Applied AI engineers embedded with customers. The quality of this platform is critical to the business's success. This is an opportunity to help define how agent platforms are built in production.

Responsibilities

  • Design, build, and operate platform services including authentication, authorization, credential brokering, routing, sandboxing, and orchestration.
  • Design interfaces for other engineers to build agents against, ensuring a clear and easy-to-follow path.
  • Build an event-driven backbone to ensure idempotent ingestion as services scale horizontally.
  • Own the deployment model, supporting hosted offerings, customer VPCs, and multi-cloud environments without bespoke builds.
  • Ensure tenant isolation by construction, preventing runs from accessing or spending beyond their allocated quotas.
  • Manage latency, throughput, and cost per run as volume increases, including production debugging.
  • Set the strategic direction for owned platform components, not just their implementation.
  • Collaborate closely with Applied AI engineers on complex deployment challenges, owning the platform while they manage customer relationships.

Requirements

  • 5+ years of experience building high-scale, complex software systems.
  • Experience building and operating a platform relied upon by other engineers, with ownership of architectural decisions.
  • Hands-on experience with primitives such as authentication, authorization, secrets management, isolation, orchestration, egress, and durable state across multiple clouds.
  • A drive to continuously improve system speed and cost-efficiency.
  • Demonstrated ability to work independently on ambiguous, loosely defined problems.
