Frontend Software Engineer

About Green Project: At Green Project Tech, we’re building the intelligence layer behind sustainable supply chains. Our UK team leads on Engage50 (supplier engagement for enterprises) and Product50 (efficient PCF / carbon footprint calculation at scale). These tools feed into Account50 and Act50, powering a full-stack sustainability platform used by enterprises and SMEs across the GPT / ACT ecosystem.
ACT, our parent company, is a global leader in sustainable products — giving us reach and credibility, with the autonomy and excitement of a startup.

Green Project is looking for a Frontend Software Engineer to help shape the future of climate tech by building beautiful, high-impact product experiences across Engage50 and Product50. This role is about moving fast, owning your work end-to-end, and using AI tools to deliver world-class interfaces that accelerate our mission to net-zero.

Responsibilities: 

• Build fast, accessible, and intuitive web interfaces in React / TypeScript.
• Work closely with design and backend teams to bring new ideas to life across Engage50 and Product50.
• Use AI-assisted development tools to code faster, ship safer, and raise the bar for quality.
• Take full ownership — write, test, deploy, and monitor your code in production.
• Contribute to shared design systems and components that power the whole GPT ecosystem.
• You’ll collaborate daily with design, backend engineering, product, and sustainability experts — a tight-knit, mission-driven team that ships fast and learns constantly.

Requirements: 

• 3–6 years of professional experience with React / TypeScript
• Strong understanding of web fundamentals (HTML, CSS, accessibility, browser APIs)
• Prior startup experience and comfort with ambiguity
• Curiosity about using AI tools in the development process
• Desire to use code and AI to accelerate the transition to net-zero
• Experience with Go or other typed backend languages (or a desire to learn) is a plus
• Interest in sustainability or climate-tech concepts is a plus

Salary range: 

The base pay range for this position is £70,000 – £90,000 annually + discretionary bonus; however, base pay offered may vary depending on location, job-related knowledge, skills, and experience.     

What We Offer: 

• Competitive salary
• Flexible / hybrid working (London-based preferred, occasional remote)
• Generous annual leave and public holidays
• Budget for learning and conferences
• Collaborative, high-ownership culture built around climate impact
