Agentic Product Engineer, Studio Platform

• Design how experts and agents work together. Agents draft the tasks, environments and graders, and experts steer and correct them. Your job is to make steering fast and reviewing easy.
• Build the environment workbench. Create the agentic framework that experts use to author every environment in Studio.
• Make long agent runs easy to follow. An expert should be able to understand a three-hour run in three minutes.
• Turn new environment types into configuration. When a customer asks for something new, it should ship in a day without an engineer writing code.
• Make quality visible. Build the agentic QC views that show what failed and why, and let people fix it where they find it.

• 5+ years of fullstack engineering experience building and shipping production software.
• You love to live in the product experience. You notice when a flow is one click too long, and you fix it without waiting for a spec.
• You’re excellent on the frontend. You know React, TypeScript and Next.js in depth. You’ve built interfaces that create enjoyable visual experiences from complex data.
• You go all the way down the stack. You’re comfortable designing the schema, the API and the background job behind the screen you’re building.
• You’ve shipped products before. You have about five years of building production software, ideally where you own a product area end to end.
• You build with AI. Coding agents are part of how you work, and you care about building the best agentic collaboration experience.
• You turn unsolved problems into a plan. You can take a vague problem from a user or partner team, find the first principles issue, and explain the tradeoffs clearly.

• Experience building tooling for data labeling, annotation, or human-in-the-loop AI workflows.
• Background in design systems, developer-facing APIs, or internal platform engineering.
• Exposure to AI tools, LLM-powered products, or real-time data and visualization.
• Experience at top-tier tech companies or fast-scaling startups.

• Your impact compounds on a massive scale. Experts are paid per task, so a fast experience directly drives the bottom line when the effects are felt across hundreds of thousands of users.
• The feedback loop is tight. Features ship daily, and feedback loops are swift and efficient.
• You see the frontier early. You watch how the newest models fail before the public does.

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.
