About the role

Software Engineer on the Automations team building autonomous systems for Mercor’s internal operations and scaleable external applications. Not a research role; design and ship production agents, end-to-end ownership from server design to evaluation frameworks, with real-world impact.

Responsibilities

  • Build and maintain MCP servers that give agents structured access to Mercor’s platform reading project state, taking management actions, and triggering communications.
  • Design and implement evaluation frameworks to measure agent decision quality and drive continuous improvement through feedback loops.
  • Develop action queues and playbook orchestration systems that allow agents to execute multi-step workflows with conditional logic.
  • Instrument agent systems end-to-end — capturing outcomes, closing feedback loops, and enabling hill-climbing on eval metrics.
  • Collaborate directly with operators to identify high-leverage automation opportunities and translate them into robust agent behaviors.
  • Debug and harden agent systems in production, designing for reliability at scale.
  • Contribute to foundational patterns and infrastructure that the rest of the company will build on.

Qualifications

  • Strong backend engineering fundamentals in Python (or equivalent modern language).
  • Experience building with LLM APIs — including tool use, structured outputs, and multi-step reasoning workflows.
  • Comfort designing evaluation frameworks and thinking rigorously about agent failure modes.
  • Ability to ship quickly and iterate on systems that interact with the real world.
  • Understanding of distributed systems, APIs, and production infrastructure.
  • Full-stack experience is a plus — owning features end-to-end will increase your impact.
