Job Description
Junior Front-End Developer
CleanTech Start-up | Up to £45k | On-Site (Southampton)
Join a fast-growing CleanTech start-up developing next-generation electric systems for the transport and mobility sector. You’ll be working on cutting-edge hardware and intuitive digital interfaces that help reduce emissions and bring smarter controls to real-world environments.
Following recent investment, the team is growing — and this is your chance to help shape the user experience of a ground-breaking green tech product from the ground up.
What you’ll be doing:
* Building and maintaining cross-platform apps (iOS, Android, Web) using Flutter and React
* Creating responsive, accessible, and visually polished user interfaces
* Connecting frontends to backend systems and embedded hardware via Wi-Fi and REST APIs
* Collaborating with designers, backend devs, and embedded engineers
* Testing your work in real-world conditions (yes, on actual boats)
* Writing clean, testable code and contributing to UI/UX discussions
What they’re looking for:
* 1–2 years' experience in mobile and/or web frontend development
* Solid foundation in HTML/CSS and a willingness to learn Flutter/Dart
* Bonus points for experience with React or hardware-connected applications
* Someone with strong attention to detail and a collaborative, curious mindset
Why join?
* Be part of a purpose-driven team tackling real-world sustainability challenges
* Work hands-on with innovative hardware — not just mockups and prototypes
* Contribute to a product already being deployed in field environments
* Get in early with a growing company that’s just secured funding
Location: On-site in Southampton (5 days/week) (Not open to relocation)
Salary: Up to £45,000
Benefits: Field-testing opportunities, collaborative engineering environment, and a mission-led culture
