Principal Software Developer
Remote Up to 70,000 Newbury

The Role
This is a hands-on Principal role, with around 90% of your work focused on backend development. You’ll be working on a large platform with high-throughput APIs, Azure Cloud and an event-driven architecture.

The business is growing and the volume of work is increasing, so they’re looking for a Principal Software Developer to join a 16-person R&D development team, made up largely of senior engineers.

You’ll remain close to the code while also helping shape technical direction, engineering standards and architecture. You’ll mentor other engineers, evaluate new technologies and work closely with customers and stakeholders to turn requirements into robust technical solutions.

What We’re Looking For

You’ll need strong experience with:

• Java or Kotlin on JVM 11+
• Spring Boot
• Enterprise backend development
• REST APIs and microservices
• SQL and NoSQL databases
• Docker/Kubernetes
• Git and modern development practices

Desirable:

• Telecommunications billing
• Azure
• CI/CD
• Linux
• Redis
• Elasticsearch or additional programming languages

You should also be comfortable operating at Principal level, making technical decisions, solving complex problems and helping other engineers develop.

Working Arrangements & Benefits

This is a remote-first role. The minimum expectation is around 2-3 visits per year to the Newbury office, although you’re welcome to spend more time there if you prefer.
The business also runs monthly and quarterly all-hands events, including summer and Christmas gatherings.
