About the Role
Join a product team at an early-stage AI infrastructure startup to design and build interfaces for tools used to create and evaluate AI agent environments. You will work across product design and front-end engineering, making technically complex workflows clear and actionable while helping shape how people work with AI systems.
What You'll Do
Design and build product interfaces from early concepts through release.
Make agent runs, evaluation results, reward signals, and quality feedback understandable and useful.
Partner with research and engineering to turn reinforcement learning and evaluation workflows into practical tools.
Talk with users, identify where they struggle, and improve the product based on feedback.
Create reusable interaction patterns and maintain strong usability, visual quality, and implementation standards.
What We're Looking For
At least 3 years of experience in design engineering, product design, or a similar role shipping product interfaces.
Hands-on front-end engineering skills and experience turning designs into working interfaces. No specific programming stack is listed.
A portfolio of shipped design engineering work and a track record of learning from user feedback.
Experience working closely with engineers and researchers on product development.
Strong product and interaction design judgment, clear communication, and comfort working with technical concepts.
Experience with developer tools, data-rich products, research software, AI agents, evaluations, reinforcement learning, or training data is valuable.
Compensation & Benefits
Annual salary range: $130,000 to $225,000. Visa sponsorship is available.
