Senior Software Engineer

We are building a multidisciplinary team to expand our secure, scalable and AI-enabled healthcare software. As a Senior Full Stack Software Engineer, you will bring validated analytical workflows into robust production applications and help shape software used across testing and production settings.

What you will do

• Design, build and operate production Python services and modern web applications on AWS.
• Take analytical workflows into production while preserving expected behaviour through disciplined testing.
• Build reliable APIs, application services and user-facing capabilities for complex healthcare workflows.
• Define and maintain versioned interfaces, automated tests and CI/CD controls.
• Collaborate closely with clinical data science to translate scientific and clinical requirements into software.
• Partner with cloud engineering on security, observability, performance and operational readiness.
• Produce clear requirements, design documentation and verification evidence for regulated development.
• Contribute to technical direction, code quality and product development engagement across the team.

What you will bring

• Typically 3-5 years of professional software engineering experience, or equivalent relevant technical ownership.
• Strong production Python experience, including FastAPI or a comparable API framework.
• Experience with AWS, containers and service-based or event-driven systems.
• Strong API design, automated testing, Git, code review and CI/CD practices.
• Experience moving analytical, scientific or prototype code into maintainable production systems.
• Clear technical communication and the ability to work across disciplines.
• Regulated, safety-critical, medical device or digital-health software experience.
• Healthcare interoperability knowledge, including HL7 FHIR or UK Core.
• Workflow orchestration, SQL, model-serving or data-validation experience.
• Familiarity with infrastructure as code and regulated software lifecycle standards.

How we work

You will join a multidisciplinary environment where engineering, clinical workflows, data science, quality and regulatory thinking come together. We value clear communication, thoughtful challenge, practical delivery and evidence-based decisions.
