Who are Greenpixie?

Greenpixie Ltd is an innovative tech start-up dedicated to measuring and reducing the environmental impact of cloud computing. We build trusted methodologies and practical tools that help organisations understand and reduce their cloud emissions.

Our products are data-heavy and technically complex, which makes clarity, usability, and design quality absolutely critical.

What are we looking for?

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.

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.

What will you be doing?

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.

What skills are we looking for?

Essential

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

Nice to have

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

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.

What We Offer?

⌛️ Flexible working hours with hybrid office space in Central London.
🍃 The opportunity to contribute to a meaningful project with a real-world impact.
🚀 Working with a fun, passionate team in a company that is growing quickly.
☁️ Exposure to cutting-edge cloud technologies and large-scale data systems.
🌍 Opportunities to attend global conferences in the tech and sustainability sectors. (even speaking opportunities if that floats your boat!)
🏝️ Build up an extra day of holiday for every year you spend with us
🎒 2 weeks global remote working allowance
💰 Competitive salary package.
📈 Share options scheme.
