Mid-Level Full Stack Developer

At UK Biobank, we’re developing new technologies that will help researchers safely access and use some of the world’s richest biomedical datasets.

This role sits within a team building a world-first automated output checking system using AI and cloud-native technologies to help improve how trusted research environments securely manage research outputs at scale.

It’s a rare opportunity to work on something genuinely new, technically challenging, and mission-driven.

Can you do it?

You’ll join a growing engineering team focused on developing and integrating the Automated Output Checking System across UK Biobank’s internal and external research platforms.

Working across backend services, frontend applications, APIs, and cloud infrastructure, you’ll help build secure and scalable integrations between access management systems, research analysis platforms, trusted research environments, and supplier-built services.

This role combines full-stack engineering, cloud technologies, and emerging AI-driven approaches, giving you exposure to modern system design while contributing to technology that supports global research.

You will be responsible for:

• Build and maintain scalable, secure, cost-efficient and maintainable full-stack applications using Python (backend) and TypeScript (frontend), including relational and non-relational database management systems on AWS.
• Develop responsive and accessible user interfaces using modern frontend frameworks (e.g., React with TypeScript)
• Assist in implementing CI/CD pipelines and automated deployment processes
• Ensure appropriate logging, monitoring, and basic observability are implemented within developed components
• Participate in development of AI-driven validation and rule-based decision logic under guidance

Is this you?

To be successful, you will have:

• Experience in full-stack software development within a product or delivery team
• Experience developing backend development using Python frameworks such as FastAPI, Flask, or similar
• Experience developing frontend applications using TypeScript and frameworks such as React or Vue
• Basic experience working with cloud platforms, preferably AWS
• Experience with microservices and API-based architectures
• Knowledge of SQL and/or NoSQL databases
