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?
