About Mednet

At Mednet, we believe the best healthcare communications do more than share information. They change how people think, feel and act.

We partner with some of the world’s leading pharmaceutical companies to turn complex science into ideas that are emotionally resonant, strategically sharp and creatively unexpected. Every strategy we build and every story we tell connects rigorous science with deeply human insight and bold creativity. Because better communication leads to better care.

This is a place for curious minds: people who thrive on intellectual challenge, bold thinking and purposeful creativity. If that is you, Mednet is where your ideas can truly make a difference.

What you'll do

• Develop and maintain front-end applications using React and TypeScript.
• Build and manage scalable back-end services using Node.js and Express.js.
• Design, implement and maintain RESTful APIs for scalable, efficient data communication between services and front-end applications.
• Integrate internal and third-party APIs across healthcare, AI and data analytics platforms.
• Support the design and implementation of API management strategies, including authentication, versioning, throttling and monitoring.
• Work with structured and unstructured databases, including PostgreSQL and Cosmos DB, ensuring efficient data storage and access.
• Write unit, integration and E2E tests across the stack: Vitest and React Testing Library on the front end, pytest on the Python/FastAPI services. Prioritise integration tests against real API endpoints.
• Optimise CI/CD pipelines and deployment workflows on Azure.
• Maintain compliance with healthcare data standards (NHS DSPT, GDPR, ISO27001) across everything you build.

What good looks like (first 6–12 months)

• Delivery of scalable, secure and high-performing features across Mednet Health's digital platforms.
• Strong ownership of front-end and back-end development, from design through to deployment.
• Trusted collaboration with the Data & AI team on intelligent, data-driven features.
• Confident handling of API integrations, database work and automated testing without close supervision.
• Positive feedback from the wider engineering team on code quality, reliability and documentation.

Expectations at the 30-day mark

• Strong understanding of Mednet Health's codebase, architecture and compliance requirements (GDPR, NHS DSPT, ABPI).
• Active contribution to sprint work and code reviews, with support from the wider team.

Expectations at the 60-day mark

• Confident ownership of full-stack features across front-end, back-end and API layers.
• Active participation in technical discussions around architecture, data and API design.

Expectations at the 90-day mark

• Acting as a trusted engineering partner to the Data & AI team.
• Leading development on key features with minimal oversight.
• Supporting production systems and helping resolve performance, security or reliability issues.
• Contributing to continuous improvement of CI/CD pipelines and engineering practices.

Must-have experience

• Bachelor's degree (2:1 or above) in Computer Science, Software Engineering or an equivalent technical discipline.
• 2–3 years' experience in full-stack software development.
• Proven experience with React, Node.js, Express.js and TypeScript.
• Strong understanding of RESTful API architecture.
• Experience with one or more databases such as MongoDB, Azure SQL or Cosmos DB.
• Proficiency in API integration and handling third-party services.
• Experience implementing automated testing (unit, integration and E2E).
• Understanding of Azure Cloud Services and CI/CD pipelines (GitHub Actions or Azure DevOps).
• Awareness of secure coding practices and data privacy regulations (GDPR).

Nice-to-haves

• GraphQL experience for complex, data-driven interfaces.
• Familiarity with API management tools such as Azure API Management, Postman or Swagger.
• Knowledge of containerisation (Docker, Kubernetes).
• Familiarity with FHIR/HL7 healthcare interoperability standards.
• Strong collaboration skills, particularly working alongside Data and AI teams.
• Excellent problem-solving, communication and documentation abilities.

Traits that thrive at Mednet

• Technically curious: you enjoy learning new tools and finding the right one for the job.
• Detail-focused: you care about clean, secure, well-tested code as much as working features.
• Collaborative: you work naturally across engineering, data and AI teams to deliver shared outcomes.
• Compliance-minded: you understand that healthcare data needs extra care, and you build with that in mind.
• Agile & adaptable: you love sprint reviews and adjust quickly as priorities shift.
• Values-led: you're motivated by purposeful work, continuous learning and helping make health more whole.
