Full job description

Description

At System C, we build technology that supports better outcomes across health and care. We are looking for a Senior Software Developer to join our CIS Oncology product suite, working on ChemoCare, a market leading system that supports the safe and effective management of chemotherapy treatment across the NHS.

This is a senior individual contributor role for an experienced developer who enjoys hands on work and taking ownership of complex technical areas. You will play an important role in ensuring reliable delivery, strong engineering practice, and the ongoing evolution of a product that clinicians depend on every day.

What you will do

Design, develop, and maintain software within the CIS Oncology (ChemoCare) product suite.
Own complex features or technical areas from design through implementation, testing, and release.
Make informed technical decisions, escalating risks or trade offs when appropriate.
Contribute to the technical direction of the product, balancing near term delivery with long term maintainability.
Work closely with QA colleagues to support effective testing, defect resolution, and overall product quality.
Write clear, maintainable, and well tested code in line with agreed development standards.
Review code written by others and provide practical, constructive feedback.
Support and mentor less experienced developers as part of day to day team working.
Provide shared third line support, investigating and resolving complex production issues when required.

What you will bring

Significant commercial experience operating as a senior software developer.
Strong professional experience with C#.
Experience contributing to or supporting a mobile application built with React Native.
Experience with modern web development, including JavaScript and CSS.
A track record of designing and building maintainable software in a team environment.
Experience working with complex or long lived codebases.
Confidence contributing to technical design and making thoughtful trade offs.
Experience reviewing code and supporting quality through good development practices.

Nice to have

Experience building and maintaining ASP.NET MVC applications.
SQL Server experience, including writing and optimising SQL for production systems.
Experience using GitHub for source control and collaboration.

At System C, you will join a collaborative, mission driven team that values ownership, integrity, and continuous improvement. We offer flexible benefits, a strong focus on professional development, and the opportunity to work on technology that genuinely makes a difference.

Apply today and help shape software that supports better care.
