Our partner is looking for a Senior Design Engineer based in Spain. We are looking for a hands-on Design Engineer who bridges the gap between product design and front-end development. You will turn ideas and designs into polished, production-ready interfaces across a platform used by energy retailers and developers, customer-facing connection flows, and the company website. Working closely with designers, engineers, and product managers, you will help shape the tools and experiences supporting the transition to a smarter, more versátil energy system. You will have significant ownership in a small, senior team where your work moves directly into production. The role also offers an opportunity to influence design systems, front-end practices, and the practical use of AI in creative and engineering workflows. Contribute significantly to the design system in collaboration with front-end engineers, developing and maintaining components, design tokens, and documentation.
- Keep the design system aligned across Figma, code, AI-assisted tools, and other workflows.
- Create interactive prototypes in code to explore concepts, test ideas with customers and colleagues, and validate directions before full implementation.
- Improve the quality of user experiences by refining interactions, motion, accessibility, performance, and interface details.
- Collaborate with engineering teams to improve front-end development, review, and release processes, ensuring design intent is consistently reflected in production.
- Work with engineers on API design and improvements,



helping make developer-facing interfaces clear, intuitive, and easy to integrate.
- Develop tools and prototypes that strengthen collaboration between design and engineering.
- Take ownership of projects from early concepts through implementation and release, contributing to a high standard of design and engineering craft.

Requirements:
- At least 5 years of experience building user interfaces in design engineering, front-end development, or a design-focused engineering role.
- Deep knowledge of React and TypeScript, alongside strong foundations in HTML, CSS, and web accessibility.
- Solid understanding of APIs, including the ability to interpret documentation, work with real data, understand developer needs, and contribute to API design decisions.
- A portfolio demonstrating both design work and implemented, production-quality interfaces.
- Recent practical experience using AI in design and engineering workflows, with a clear understanding of where AI adds value and where it falls short.
- Experience contributing to a design system that is actively used by product or engineering teams.
- Strong collaboration and communication skills, with the ability to explain design decisions to engineers and technical constraints to designers.
- Excellent written communication skills, particularly important in a remote-first working environment.
- Strong attention to detail and a passion for refining the finer aspects of interface quality, including transitions, spacing, and edge cases. -
