Senior Design Engineer
Quick Summary
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,
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 flexible 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.
-
Build, develop, and ship production-ready user interfaces across the core platform, customer-facing connection experience, and website, working directly in the codebase.
-
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.
-
Help shape the team's use of AI for prototyping, exploration, development, and workflow improvement, while recognizing its limitations.
-
Take ownership of projects from early concepts through implementation and release, contributing to a high standard of design and engineering craft.
