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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
