Overview of Role
The Senior Software Engineer (.NET) will play a key role in designing, developing, and maintaining backend services and APIs that power Care Control’s platform. This role includes significant responsibility for backend architecture, coding standards, and improving engineering practices across the team. The engineer will work with modern .NET Core patterns, contribute to SQL development, and collaborate closely with frontend teams to enable high-quality product delivery. This role will help strengthen Care Control’s backend foundation as we mature our SDLC and engineering capabilities
Role Responsibilities
* Design, develop, and maintain backend services and APIs using C# and .NET Core.
* Take ownership of backend architecture and evolve coding patterns, documentation, and technical standards.
* Write efficient SQL queries and stored procedures, contributing to database performance and reliability.
* Collaborate closely with frontend engineers to design robust, well-structured API contracts.
* Participate in code reviews, ensuring adherence to quality, maintainability, and architectural standards.
* Work with the Engineering Manager to improve backend development practices and support the growth of the engineering function.
* Provide technical mentorship to junior and mid-level engineers as the backend team expands.
* Collaborate with offshore developers to align delivery and maintain quality across distributed teams.
* Design and maintain data access layers using appropriate ORM patterns (e.g. Entity Framework Core, Dapper), ensuring performance, maintainability, and clear separation between application and database logic.
* Understand containerisation and AKS concepts to support the future deployment model and ensure backend services are cloud-ready.
What Success Looks Like / Key Metrics
* High-quality, maintainable backend code delivered consistently.
* Reliable API functionality supporting frontend and mobile applications.
* Improved database performance through efficient SQL and stored procedure design.
