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.
