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
- We are a fast-growing start-up with a lot of moving parts. We want someone comfortable working independently, making decisions, and collaborating closely with others
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
