Principle Design Engineer
Mentions vibe coding explicitly as an optional support; emphasizes prototyping-in-code and use of AI copilots (Claude Code) to accelerate design/dev workflows.
About the Role

You will prototype and ship GUI and programmatic interfaces, collaborate with product and engineering, and help define product direction for developer tools and platforms.
Job Description
Role
We are hiring a hands-on Design Engineer to shape the developer experience across our products. This role blends visual UX and frontend engineering: you will prototype in code, iterate rapidly from low- to high-fidelity, and help define product strategy for both GUI and programmatic interfaces (APIs, CLI). You will work on our open-source framework (MooseStack) and our commercial hosting platform.
Team & Reporting
You will start reporting to the Co-founder/CPO and work closely with the founding team, product management, product marketing, and core engineering. This is an individual-contributor role with opportunities to mentor a designer on the team and to grow into a function lead.

- Leverage AI tooling to accelerate workflows and focus on differentiated human design skills
Qualifications
