Senior Design Engineer

About the role

A partner company is looking for a hands-on Senior Design Engineer based in Switzerland, bridging product design and front-end development. You will turn ideas and designs into production-ready interfaces across a platform used by energy retailers and developers, customer-facing connection flows and the company website. You will work closely with designers, engineers and product managers, own projects from concept to release, and help shape design systems, front-end practices and the use of AI in creative and engineering workflows.

Key responsibilities

• Build, develop and ship production-ready user interfaces across the core platform, customer-facing connection experience and website, working directly in the codebase.
• Contribute to the design system with front-end engineers, developing and maintaining components, design tokens and documentation, keeping it aligned across Figma, code and AI-assisted tools.
• Create interactive prototypes in code to test ideas with customers and colleagues before full implementation.
• Refine interactions, motion, accessibility, performance and interface details to improve user experience.
• Collaborate with engineering teams to improve front-end review and release processes, and work with engineers on API design so developer-facing interfaces are clear and easy to integrate.
• Develop tools and prototypes that strengthen collaboration between design and engineering, and help shape the team's use of AI for prototyping, exploration, development and workflow improvement.

Required profile

• 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, with strong foundations in HTML, CSS and web accessibility.
• Solid understanding of APIs, including interpreting documentation, working with real data and contributing to API design decisions.
• Portfolio showing both design work and implemented, production-quality interfaces.
• Recent practical experience using AI in design and engineering workflows, and experience contributing to an actively used design system.
• Ability to take an idea or loosely defined problem through to a shipped feature without a detailed specification, and strong written communication skills in a remote-first environment.
• Interest in the energy transition and electrification.

Required skills

• React and TypeScript
• HTML, CSS and web accessibility
• API design and interpretation

What we offer

• Competitive compensation and an attractive employee stock option program.
• Remote-first working across Europe, with the option to work from an office in Oslo or a co-working pass.
• Dedicated time for AI learning, an internal skills library and a budget for relevant tooling.
• Three team off-sites per year and a home-office setup stipend.
