Review code and provide constructive, practical feedback
Support and mentor less experienced developers as part of everyday team working
Contribute to shared 3rd line support, investigating and resolving complex production issues when required

Experience using GitHub for source control and collaboration
Strong analytical and problem-solving skills both at a strategic and tactical level
Strong SQL Server experience, including writing and optimising production queries
Experience working with complex or long-lived codebases
Confidence contributing to technical design and making informed trade-offs
A pragmatic, calm approach when dealing with ambiguity or pressure
Clear communication, including explaining technical constraints to non-technical stakeholders

Nice to have

Experience with React Native
Experience in writing automated unit tests using NUNIT
Good understanding of waterfall, agile and scrum development methodologies, and their practical application.
Experience in .NET 10 and other latest technologies including AI integration
Experience in TypeScript

Why join System C?

You will work on software that genuinely matters, alongside people who value collaboration, ownership, and integrity. We support flexible working, encourage reflective practice, and value those who are comfortable navigating change while keeping quality and patient safety at the forefront.
