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.

Responsibilities

The Systems, Development and Data team is key function of the business, responsible for all internal and external facing systems, both third-party (SaaS) and internally delivered solutions. We build key internal and external tools, and make business processes flow smoothly, automating where we can, and making end-user experiences great where people need to be involved. We also own business data management; we deliver complex reporting outputs and maintain our data warehouse and processing pipelines.

We’re a friendly and diverse team, constantly helping each other out and supporting ongoing learning and development. We’re remote-first, and distributed across the UK, with occasional social get-togethers and workshops (usually at most once per quarter).

We do use AI where it makes sense in our workflows, including agentic coding systems and tools, but are thoughtful when it comes to selection of tools and use of automation in our day-to-day activities. The ideal applicant will bring a similar curious-but-sceptical attitude, be happy in a fully remote async-heavy team, and be aligned with our team values of inclusivity, openness, and curiosity.

You’ll have a head for architecture and the big picture but be happy stepping down into the detail to implement required changes. You’ll be a systems thinker, with experience working with distributed systems, business events, real-time systems and engineering reliable systems.

You’ll be confident and happy to work independently, directly speaking with stakeholders and internal customers to ensure you’re delivering what they need, while ensuring we stay compliant and secure. You’ll have good interpersonal skills and be happy thriving in a high-velocity environment, in a rapidly changing industry.
