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.
You'll lead one of their core teams, diving deep into production systems, identifying bottlenecks, and driving long-term architectural decisions that support scale, resilience and product growth.
What You'll Do
- Own and evolve platform architecture across distributed systems.
- Analyse production systems to uncover and resolve performance issues.
- Lead backend design using Kotlin (or JVM), supporting a polyglot mindset.
- Collaborate across engineering to improve practices, tooling, and system design.
- Mentor and influence technical direction company-wide.
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.
- Clear communicator who enjoys cross-functional collaboration and technical ownership.
