Project Overview

Join the team as a .NET Developer and work on a core platform for a leading UK provider of roadside assistance and insurance. The SMR domain (Service, Maintenance & Replace) supports mechanics and service operations by ensuring the right parts are selected for jobs booked - quickly and accurately.

Your main focus will be to enhance the parts-picking algorithm to improve prediction quality and operational efficiency.

Design, develop, and maintain backend services using C#/.NET
Build and evolve data-driven logic to improve parts prediction and selection accuracy
Integrate and unify data from multiple sources (API/DB/external systems)
Write efficient, maintainable SQL and support data-quality initiatives
Develop and maintain REST APIs used by other services and operational tools
Contribute to architecture decisions with a focus on reusability, scalability, and maintainability
Participate in code reviews, technical workshops, and sprint ceremonies
Improve engineering practices (testing strategy, CI/CD, observability, performance)

Requirements

Min. 5+ years of commercial experience as a Backend / .NET Developer
Strong command of C# and modern .NET (building production-grade services)
Hands-on experience with Azure (e.g., Repos, Pipelines, Key Vault, App Insights or equivalent)
Strong experience with SQL and relational databases (query optimization, data modeling)
Solid understanding of backend best practices (Clean Code, SOLID, design patterns, API design)
Proven ability to work with ambiguous problem spaces - creative, puzzle-solving mindset
Comfortably designing solutions that are not fully specified and require independent ownership
Fluent in Polish and advanced English (B2/C1)

Nice to have:

Experience with Snowflake and/or Microsoft Dynamics integrations
Experience in data-heavy domains, prediction/selection logic, or operational tooling
Strong observability mindset (logs, metrics, traces)
