Member of Technical Staff, Product Designer

About Us
We are a small team of researchers and engineers focused on pushing the frontier of what agents are capable of. We believe the next leap in agent performance will come not from bigger general models, but from specialization and continual learning: agents that get better at their specific job the more they do it. We build the systems that make this possible, turning real-world usage into lasting improvement.

Summary
We are looking for an experienced product designer to shape how engineers and researchers build, train, evaluate, and improve agents on our platform. You will design for technical users across a web app, APIs, CLI, and SDKs, and you will make complex systems feel clear and easy to use. As our first designer, you will set the design direction for the company and work closely with engineering, research, and our forward-deployed team. You will also design the experience of how agents improve over time, which is a new problem with no established playbook.

Responsibilities

• Own the end-to-end product experience for our platform, from first use to running agents in production.

• Design workflows for creating evaluations, launching training runs, comparing results, and deploying models.

• Design clear ways to show what an agent is doing and how it is improving, including traces, metrics, experiment results, and model versions.

• Shape the developer experience across the web app, CLI, APIs, SDKs, and documentation.

• Build working prototypes in code to test ideas quickly and explore technical constraints.

• Talk directly with customers and internal users to understand their workflows and find the biggest problems to solve.

• Create and maintain a design system that scales as the product grows.

• Work closely with engineers through implementation, and hold a high bar for quality and detail.

• Help define our brand and visual identity as we come out of stealth.

Qualifications

• Product design experience, with a strong focus on developer tools, infrastructure, or other highly technical products.

• A portfolio that shows complex technical products made simple, with clear thinking about workflows and systems, not just screens.

• Excellent interaction, visual, and UI design skills.

• Comfortable building prototypes in code with modern tools such as Cursor, Claude Code, or v0, and comfortable reading APIs and code.

• A good understanding of how developers work, including the terminal, Git, APIs, and debugging.

• Experience designing data-heavy interfaces such as dashboards, observability tools, or experiment tracking.

• Able to work independently with a lot of ambiguity, and to make good decisions with limited information.

• Clear written and verbal communication.

Nice to Have

• Experience designing for ML engineers or researchers, such as training, evaluation, or experiment-tracking tools.

• Experience shipping AI or agent products, including workflows that move between human review and autonomous action.
