Enjoy being hands-on and thrive in fast-growing, product-led environments?🌍🌱
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 Technical Lead, you will manage a small pod while remaining hands-on with day-to-day coding.

What You'll Do
- Design, build and evolve platform architecture across distributed systems.
- Lead a small squad (technical leadership and people management)
- Contribute to backend design using Kotlin (or JVM), supporting a polyglot mindset.
- Collaborate across engineering to improve practices, tooling, and system design.
- Grow and shape your team
Tech & Environment
- Kotlin (JVM), distributed systems, microservices, CI/CD
- Cloud-native platforms (AWS/GCP), modern engineering culture
What They're Looking For
- Deep JVM/backend experience; Kotlin a bonus, but not required.
- Strong systems thinker with a track record of architectural leadership.
- Experience scaling production systems in fast-moving product environments.
- Experience with leading, technical ownership and people management
