About the role

Join us in building safe, compliant software for patient care

We're looking for a Senior Software Developer to join our Clinical Scientific Computing (CSC) service, taking the prototype and in-house software developed within Medical Physics and turning it into quality, production-ready systems that meet UK requirements for Software as a Medical Device (SaMD). You will do this within the framework of our ISO 13485-certified Quality Management System, helping to validate, test and maintain the software we already use, as well as the new systems we build. This is a hands‑on development role; therefore, if you enjoy writing good quality code, take pride in getting the detail right, and want your software skills to make a real, tangible difference to patients, this could be the role for you.

Working for our organisation

As one of the largest acute teaching Trusts in England, we offer learning and development opportunities to help you achieve the career you aspire to. UHS is rated ‘Good’ by the CQC and in the latest national NHS Staff Survey, we were in the top 10 acute trusts for staff engagement and for staff recommending the hospital as a place to work or receive care.

We support flexible working and will consider requests taking into account the needs of the service.

• UHS employees are able to access a range of NHS discounts
• are entitled to a minimum of 35 days paid holiday (pro rata)
• we offer a generous pension scheme.

Southampton is an attractive place to live and work situated on the south coast, with an international airport and direct trains to London. The New Forest National Park and beaches of the Jurassic coast are also right on our doorstep. The city offers living costs 30% lower than London and 17 schools rated outstanding by Ofsted.

We believe that using technology wisely shows strong time management and commitment to innovation. However, personalising your recruitment application to highlight your unique skills and experiences is crucial. Relying too heavily on generic, AI-generated content instead of drawing from your own strengths and accomplishments may lead to your application being rejected if multiple candidates present identical or similar information.

We are a multidisciplinary, close-knit team where clinical scientists, computer scientists, and software engineers work side by side. Together, we design, build, and maintain bespoke clinical and healthcare software, collaborating closely with healthcare scientists and clinicians across the Trust. We combine the rigour of a regulated, ISO 13485-certified QMS with the pace and creativity of modern software development—giving you the chance to work on genuinely novel in-house systems, rather than off‑the‑shelf configuration.
Our team values autonomy, technical depth, and continuous learning. We have won several grants and innovation competitions for the software products we have designed and delivered. You will be working alongside experienced developers and clinical scientists, with plenty of opportunity to build your knowledge of regulated software development and grow with the team. Furthermore, we maintain strong links with the University of Southampton and proudly run the STP training programme in Clinical Scientific Computing, alongside bespoke work experiences, internships, and fellowships.

This role sits within the CSC software development stream directly reporting to the Lead Computer Scientist – Software Development and accountable to the Head of Clinical Scientific Computing.

What you'll be doing

• Developing production-quality software, taking prototype code from within CSC and implementing, re‑coding or refactoring it so that it meets the current regulations for Software as a Medical Device (SaMD).
• Turning user requirements into a technical plan, from new design work to substantial redesign of existing systems, including modifying code in older technologies where needed.
• Validating, testing and documenting our software, including risk assessment and change control, and managing your own development through the QMS with version control and disaster recovery in place.
• Supporting Medical Physics computing systems, providing first‑line troubleshooting for SaMDs and any relevant computer systems in line with our Service Level Agreements.
• Training and advising colleagues in Medical Physics on the use of computing equipment and software, and on good practice in software quality management.

What we're looking for

• A good (1st or 2nd class) honours degree in computer science, physics, engineering, or a related subject (a higher degree, such as an MSc, in computing science or software engineering is desirable).
• Experience working with databases; experience with both SQL and NoSQL (e.g. MongoDB) databases is desirable.
• Experience developing software within a regulated industry, compliant with ISO/IEC software standards, including formal software risk assessment, validation and testing.
• Direct experience of working with a software quality management system and of using and managing version control; experience with continuous integration, continuous deployment and provisioning tools is an advantage.
• A logical, collaborative approach, with the initiative to work autonomously, good attention to detail, and experience of working in multidisciplinary teams (experience of Agile teams is desirable).
