Software Engineer, Automation

Job summary

Responsibilities

As a Software Engineer on the Automations team at Mercor, you’ll join a small, high-leverage engineering group building the autonomous systems that run Mercor’s internal operations — and eventually, operations at scale for the companies we serve.

• 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.

What they're looking for

• 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.
