The Senior Software Engineer will join our Systems, Development and Data team to grow our software engineering function and support our expansion as we support the rapidly growing business in providing market-leading onboarding, support, and account management experiences.

You’ll work on our estate of Python microservices (and related Rust modules), web applications, and API integrations - as well as working to integrate and configure our SaaS and hosted platforms - to build new features, understand and resolve issues, and design future work. You’ll also build web frontends for some applications and internal tools, and take ownership of full-stack end-to-end delivery.

We do interesting stuff, as well as the more straightforward bits of data plumbing - numerical routing and allocation optimisation, AI image analysis from field engineers, sentiment analysis, network analysis, low-level network monitoring, and lots of interesting geospatial bits and pieces.

As our senior software engineer, you’ll support junior engineers and help them develop into great software engineers. You’ll also help ensure that we keep our quality standards high, and that we’re developing the right tools to solve the business’ long-term challenges, even where requirements and demands are unclear or changeable.
