Software Engineer – Polyglot-Friendly Team, Big Impact on Clean Energy
Location: 2 days onsite in London (Zone 1)
Are you a JVM engineer curious about Kotlin – or already loving it?
Want to solve complex problems that contribute to a greener, more sustainable world?
Join a high-calibre engineering team building modern, customer-facing and energy-focused systems in one of the UK’s most exciting clean tech companies.
As the Software Engineer, you will:
- Design and build well-structured backend systems using Kotlin (or learning it quickly if you’ve worked with other languages before).
- Collaborate closely with product and design teams to ship high-impact features to thousands of customers.
- Contribute to a culture that values curiosity, bold thinking and raising the bar – whether you’re an introvert or love a whiteboard.
- Champion clear communication and collaborative problem-solving within a modern engineering setup.
- Help shape a product that’s transforming energy usage at scale, from the inside out.
Tech Stack: Kotlin (JVM), modern backend architectures, CI/CD, microservices, cloud-native platforms (e.g. AWS, GCP)
What we\’re looking for:
- Either hands-on Kotlin or JVM experience with a proven ability to learn and use other languages.
- Experience in modern tech companies with good engineering practices.
- Strong communicator – you don’t need to be loud, just clear and thoughtful in how you express ideas.
- Appetite to challenge the status quo, take ownership and improve systems and ways of working.
- We’re not the right place for engineers coming from highly structured, slow-moving environments – they are looking for Engineers who like to take risks!
This is a brilliant opportunity to join a team where your ideas are valued, your skills are stretched and your work genuinely makes a difference in the fight for a more sustainable future.
Curious? Excited?
Apply now and let’s build the future of clean energy together.
