Job description

About the Role

Join a growing product team building AI infrastructure for creating and evaluating reinforcement learning environments. You will combine full-stack engineering and product design to make technically complex workflows clear, useful, and actionable for users.

What You'll Do

  • Design and build interfaces across the platform and marketplace, taking ideas from early concepts through launch.

  • Make agent runs, evaluation results, reward signals, and quality feedback understandable and actionable.

  • Partner with research and engineering teams to turn complex reinforcement learning and evaluation workflows into useful tools.

  • Talk with users, observe where they struggle, and improve the product based on feedback.

  • Create thoughtful interaction patterns and maintain high standards for usability, visual quality, and implementation.

What We're Looking For

  • At least 3 years in design engineering, product design, or a similar role, with a track record of shipping product interfaces.

  • Primarily full-stack engineering experience, including front-end skills and demonstrated design-engineering work that turns designs into working interfaces.

  • A portfolio showing shipped work and strong visual design, plus experience improving products through user feedback.

  • Technical education or strong technical fundamentals, with the ability to understand complex concepts and explain them clearly.

  • Experience working closely with engineers and researchers; familiarity with developer tools, data-rich products, research software, AI agents, evaluations, reinforcement learning, or training data is useful.

  • Good product judgment, clear communication, and the ability to work independently in an early-stage environment. Experience creating reusable interface patterns is also valuable.

Compensation & Benefits

Base salary range: $130,000 to $225,000 USD annually. Visa sponsorship is available.

Location

On-site in San Francisco, California, with remote work also available in the United States or Singapore.
