Role
Who you are
- We are looking for a design-led UI / Frontend Developer with strong engineering fundamentals and some backend experience
- This role is for someone who cares deeply about how products look, feel, and behave, not just whether they technically work
- You should be comfortable shaping interfaces from rough ideas, improving flows, and building intuitive UI for complex information
- Strong experience building modern front-end applications with React (and ideally Next.js)
- Excellent visual and interaction design instincts. You notice spacing, hierarchy, and behaviour issues instinctively
- Experience managing React state/caching (such as: useContext, TanStack Query, Redux)
- Strong HTML, CSS, and modern JavaScript / TypeScript skills
- Experience working with APIs and a solid understanding of backend concepts
- Confidence designing UI from rough inputs using component libraries (not just implementing finished designs)
- Clear communication and a product-focused mindset
Desirable
- Backend experience using Python (FastAPI, Flask, or similar)
- Experience with data-heavy or B2B products
- Familiarity with AWS or modern cloud platforms
- Experience contributing to or maintaining a design system
- Interest in sustainability and reducing the environmental impact of cloud computing
What the job involves
- You’ll work closely with product, data, and backend engineers, owning the front-end experience end-to-end while contributing backend changes where appropriate
- This is a product-minded role with real ownership and influence
- Owning and improving the front-end experience across Greenpixie products
- Designing and building UI as you go, extrapolating from rough concepts rather than relying on polished Figma files
- Developing front-end applications using React and Next.js
- Using modern UI frameworks such as shadcn and Tailwind UI to build thoughtful, consistent interfaces
- Turning complex data and sustainability metrics into clear, usable, human-friendly experiences
- Working closely with backend APIs and contributing small backend changes where it helps unblock or improve UX
- Collaborating with product, platform, and data teams to shape features, not just implement them
- Shipping iteratively, polishing details, and responding quickly to user feedback
- Helping evolve shared UI patterns and components rather than rebuilding one-offs
- Documenting decisions and implementation clearly and pragmatically
- AI development tooling such as Claude Code and Cursor is encouraged. Our technical tests will assess candidates both with and without AI support
