Job description

ABOUT MERCOR

Mercor’s mission is to organize human intelligence for the AI economy. We build the infrastructure that enables frontier AI labs and enterprises to train, evaluate, and improve AI on real-world professional work. More than five million experts have joined our network, and we pay out over $5 million daily for their knowledge and expertise.

We built our training and evaluation infrastructure alongside the world’s leading AI labs. Now, we’re bringing those capabilities to enterprises across industries, enabling them to train, evaluate, and improve AI using their own expertise and standards. Our APEX benchmarks measure how AI performs on economically valuable work, while our enterprise evaluations and post-training capabilities turn those insights into measurable improvements across real-world workflows.

Our work sits at the intersection of frontier AI, human expertise, and real-world application. We’re solving problems few companies have encountered, with the opportunity to influence what the world’s most advanced AI systems become capable of doing. We’re looking for people who bring different perspectives, take ownership, exercise sound judgment, and hold themselves to an exceptionally high standard. You’ll have the opportunity to do consequential work alongside talented colleagues who challenge one another, collaborate openly, and share a commitment to excellence.

Mercor is profitable and recently raised a $750 million Series D at a $20 billion valuation. We work in person five days a week in San Francisco, New York, and London.

ABOUT THE ROLE

We think knowledge workers will need agents that are powerful (same access you have), proactive (do it before you ask it), and personalized (continually learn about you).

We built Indigo, an agent designed to be your coworker. Indigo powers both our internal AI tools and our enterprise agent deployments. You, your colleagues and thousands of customers will spend hours each day on Indigo. Through Slack, the web, or text, Indigo will help them brainstorm, plan, and deliver.

We are looking for engineers who are excited to make agents that help people to achieve more .

WHAT YOU’LL WORK ON

Making a magical experience is really about getting a thousand tiny details right:

• What colors should we use for the status dot to signal “done and unread” vs. “waiting on input”?
• How can we copy the shortcut mappings people are used to on Claude Code when many shortcuts are already repurposed by the browser?
• What happens if users split out 64 panes? What happens if they upload 100 files?
• How much of the thinking trace do people actually want to see?
• Should sending new chat messages automatically scroll the active window down?
• Do chat sidebars scale to agent swarms? What happens when people have 50 parallel agents?

WHAT WE’RE LOOKING FOR

• Detail-obsessed perfectionist
• You think taste cannot be delegated to an agent
• You are comfortable with tight deadlines
• You can invent new experiences that don’t have analogs
• You believe diffusion of agents throughout the economy is one of the most important missions of this decade

HOW WE WORK

• Writing is thinking
• Quality and speed
• Freedom and responsibility
• Ruthlessly outcomes-oriented
• Think in systems
• 5 days/week on-site in SF
