Senior Software Engineer (C++)

We're looking for a Senior Software Engineer to design, build, and maintain high-quality software at the heart of our health technology products.

You'll work closely with product, clinical, and engineering teams to deliver software that is reliable, secure, and built to the standards that healthcare demands. You'll contribute to technical decisions, champion best practices, and support the growth of engineers around you, all without losing sight of what matters most: shipping great software.

This is a hands-on role for someone who takes pride in their craft, thrives in a collaborative environment, and understands the real-world impact of getting it right in health tech.

This is a hybrid role based out of our Birmingham HQ, with the expectation that the successful candidate will attend the office 1–2 times per month as required.

• Software Development: Design, develop, test, and maintain software solutions for health products across the full development lifecycle.

• Architecture and Design: Contribute to the design of scalable, secure, and maintainable systems, with a focus on healthcare requirements and data integrity.

• Code Quality: Write clean, efficient, and well-tested code. Participate in code reviews and uphold engineering best practices.

• Health Domain Delivery: Build systems that support clinical workflows, patient data, and regulatory compliance.

• Collaboration: Work closely with product managers, clinicians, designers, and other engineers to deliver high-quality features.

• Problem Solving: Diagnose and resolve complex technical issues in production and development environments.

• Continuous Improvement: Improve existing systems through refactoring, modernisation, and automation.

• Mentorship: Support and guide junior engineers through technical feedback and day-to-day collaboration.

• Technical Experience: Strong commercial experience as a Senior Software Engineer delivering production systems.

• Programming Skills: Proficiency in C++

• Health or Regulated Systems Experience: Experience working on healthcare, life sciences, or other regulated software environments is desirable.

• System Design: Experience contributing to system design, APIs, and integration of complex systems.

• Quality Focus: Strong understanding of testing, reliability, and maintainability, with attention to detail.

• Collaboration and Communication: Ability to work effectively with cross-functional teams and communicate technical concepts clearly.

• Adaptability: Willingness to learn new technologies and adapt to evolving product and regulatory needs.

• Continuous Learning: A mindset of ongoing learning and professional development.
