Our partner is looking for a Senior Product Design Engineer based in Spain. Own core product experiences end to end, combining exceptional product design judgment with strong design engineering skills. The role sits at the intersection of product design, frontend engineering, design systems, and interaction design.

The environment is remote‐first and async, with a high degree of autonomy, direct feedback, and a strong emphasis on craft and thoughtful collaboration. This is an opportunity to shape both the product experience and the design system behind a globally used scheduling platform. Translate product problems and hypotheses into high‐quality designs, prototypes, and production‐ready frontend components.

Build and test working prototypes using modern AI‐assisted development tools such as Claude Code, Cursor, and v0, selecting the fastest approach for answering product and design questions. Deliver components that product engineers can use directly, ensuring correct semantics, complete interaction states, accessibility, and production‐quality implementation. Design, engineer, and maintain custom components and primitives rather than relying on generic third‐party UI libraries.

Apply motion and animation thoughtfully, using it to clarify interactions and improve the experience without adding unnecessary complexity. Refine the details that elevate product quality, including empty states, error messaging, loading behavior, transitions, and other interaction nuances. Collaborate openly with product and design leadership, sharing work early, incorporating feedback, and allowing technical and product constraints to inform design decisions.

Proven experience as a product designer who has evolved substantially into design engineering,



with ownership of complex and ambiguous product areas from problem definition through launch and iteration. Exceptional product design craft combined with strong frontend engineering skills in HTML, CSS, TypeScript, and React. Demonstrated ability to independently turn product and design concepts into polished, working implementations without relying on another engineer to make ideas production‐ready.

Strong experience designing and engineering custom UI components and primitives, rather than primarily consuming third‐party component libraries. Strong understanding of motion design principles, including timing, easing, choreography, and the judgment to determine when animation adds value. Deep familiarity with web standards and browser‐native platform primitives, with the ability to understand what the browser already provides before introducing additional libraries.

Ability to understand the technical architecture behind product experiences, including APIs, data models, application state, and technical constraints. High‐trust, high‐autonomy mindset with the ability to thrive in a remote and asynchronous environment without constant supervision. Open‐source contributions or publicly available side projects demonstrating your design and engineering work.

Familiarity with locale‐ and time‐aware web APIs such as Intl.Fully remote: Work from anywhere in the world. Work in a stable, family‐friendly environment focused on trust, kindness, and sustainable high performance. Use modern AI development tools as part of the everyday product and engineering process.

Shape core product experiences and reusable design infrastructure used by a globally distributed user base. Design and engineering ownership:
