SW / Integration Engineer | Claims & Policy System Rebuild | Remote (UK) | £50,000-£65,000 This is a hands-on delivery role with a defined path to architecture. You will own all inbound integration delivery on a ground-up rebuild of a core Claims and Policy Record system, working within a small, focused team alongside a Senior Software Engineer, BA, Data Engineer and Infrastructure Engineer.
The role is explicitly positioned as the internal successor to the Enterprise Architect seat, with the rebuild providing the platform to build that breadth over time. If you want visible, meaningful output from day one, use AI tools like Claude Code as a serious part of your engineering practice rather than a novelty, and want a genuine long-term pathway rather than a lateral move, this is worth reading.
You will
Design and build all inbound integrations: Boom, Dayinsure and ShareDo. Own the claims import pipeline end-to-end. Build the notes and flags features within the new system. Work with the Senior Data Engineer on mapping specifications so integration inputs align with pipeline requirements.
Write clean, maintainable, well-documented code and contribute to technical standards in code review. Use AI coding tools (e.g. Claude Code) to improve output quality and speed, applying strong prompt engineering without compromising on sound engineering principles, testing or code ownership.
Support UAT, go-live and post-go-live BAU transition. WHAT WE'RE LOOKING FOR 3+ years in software or integration engineering, with proven production experience building REST API integrations end-to-end. Strong .NET / C# development: clean, maintainable, well-documented code, able to work independently on discrete workstreams.
Microsoft SQL Server (MSSQL 2022): T-SQL, schema design, query optimisation and data mapping across source systems. Experience designing and building document import pipelines, managing end-to-end data ingestion from multiple sources.
Data mapping and transformation experience, including producing mapping specifications in collaboration with Data Engineers. PII handling and data redaction: privacy-by-design applied to integration builds. Comfortable using AI coding assistants (e.g.
Claude Code, Copilot) independently, with an appetite for good prompting practice grounded in solid fundamentals, not a substitute for them. Nice-to-have Experience in insurance, financial services or another regulated i...
