Job description

Job Title: Full-Stack Developer (Sustainability & Decarbonisation Software)

Salary: Competitive + benefits (DOE)

You’re a developer who wants your code to mean something . Not just another feature factory - but software that helps real organisations cut carbon, make smarter energy decisions, and build a more sustainable future.

This is a fully remote Full-Stack Developer role in an Asset Sustainability team building a mature, mission-led platform used to manage and optimise physical assets (think buildings, equipment, distributed energy, and operational data). The product supports long-term capital planning, energy monitoring, and decarbonisation roadmaps - helping users prioritise the changes that will genuinely move the needle.

No sustainability or energy industry experience is required. If you’re strong in Python 3+ , PHP 8+ , and MySQL 8+ and you care about sustainability, you’ll feel at home here.

What you’ll be doing

• Building and maintaining features across front end and back end (web + mobile-deployed web apps)
• Refactoring and modernising an established application while adding new modules and functionality
• Designing database structures and improving performance, quality, and responsiveness
• Collaborating with stakeholders, ops / support, and other devs to deliver scalable, enterprise-ready solutions
• Reviewing code, sharing feedback, and spotting improvements with a positive, pragmatic mindset
• Troubleshooting bugs and strengthening security, accessibility, and maintainability

What you’ll bring

• 5+ years ’ commercial web / software development experience (degree optional if your track record is strong)
• Extensive hands‑on use of PHP 8+, Python 3+, MySQL 8+ (PostgreSQL also welcome)
• Solid fundamentals in HTML, CSS, JavaScript and experience with Angular 18+
• Comfort deploying and managing Unix-based servers, plus CI / CD and Git workflows
• A clear communicator who can work independently in a remote team - and talk through decisions confidently

If you want a remote full‑stack developer role where your work supports decarbonisation and sustainability every day, this is it.
