The Senior Software Engineer (CALC engine) is a specialised role working on a complex Java based high-performance OLAP engine. Our engine is a multi-dimensional calculation engine with its own modelling language. The model declaration is dynamically compiled into efficient runtime objects.

We use AI-driven development innovation a little differently on the engine because the complexity of the code is often beyond what the AI tooling is capable of. That said, Claude Code is a major part of our lifecycle and is used to focus more efforts on the key areas that drive customer value.

The successful candidate will be working right in the core of the engine, where correctness and quality are as important as calculation performance.
