Junior Front End Developer jobs in Manchester

Help build one of the world’s first AI-driven output checking systems for health research.

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 what is believed to be the world’s first automated output checking system for trusted research environments using AI and cloud-native technologies to help ensure researchers can only export files regarded as safe.

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:

• Building and maintaining 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.
• Developing responsive and accessible user interfaces using modern front-end frameworks (e.g., React with TypeScript)
• Assisting in implementing CI/CD pipelines and automated deployment processes
• Ensuring appropriate logging, monitoring, and basic observability are implemented within developed components.
• Participating 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
• Developing backend development using Python frameworks such as FastAPI, Flask, or similar
• Frontend applications using TypeScript and frameworks such as React or Vue
• Working with cloud platforms, preferably AWS
• Microservices and API-based architectures
• SQL and/or NoSQL databases
