LOCATION: Stamford Bridge, London

CONTRACT: Permanent, Full Time

JOB FUNCTION: Deliver the Club's digital product roadmap by building world-class digital experiences for supporters.

About the Role:

We're hiring a Senior Full Stack Engineer to design, build and deliver digital features end-to-end. We are looking for someone with a Strong product engineering mindset, with experience working directly with Product Managers and Designers to discover, prototype, test and deliver fan-facing digital experiences. Able to use AI-assisted development tools to accelerate delivery while maintaining high standards of quality, security, accessibility and performance.

You'll own the journey: technical approach, implementation, testing, accessibility, performance and security. AI accelerates the work; you remain accountable for it. Your code is handed to our external development partner for review and release, so the bar is production quality from day one.

This is a role for a full stack developer who enjoys ownership, product thinking and building well — not just shipping fast. You'll help us experiment quickly, validate ideas with real users and turn successful concepts into production-ready experiences.

What you'll do:

• Partner with Product Managers to turn requirements into technical solutions and delivery plans
• Rapidly prototype ideas using AI-assisted tooling to validate solutions before committing to production development
• Build responsive, accessible, production-ready web experiences for our app, desktop, mobile browsers and web views, on top of our design system
• Design and integrate with Contentful and contribute to content model design where needed
• Build and consume APIs, and integrate third-party services
• Use AI-assisted development tools to accelerate delivery while critically validating all AI-generated outputs
• Write automated tests and instrument features for analytics and experimentation
• Prepare code for review by our external development partner and collaborate through the release process, addressing feedback and supporting deployment
• Contribute to our engineering standards, reusable components and ways of working

What you'll bring

Essential

• Strong commercial experience shipping modern web and app applications end-to-end
• Excellent TypeScript and React. Familiarity with Next.js or similar modern React frameworks is a plus
• Experience with React Native
• Experience with headless CMS platforms (Contentful preferred) and API integration
• Solid grasp of software architecture, testing, accessibility, security and performance
• Confident using modern AI-assisted software development tools (e.g. Claude Code, Cursor, GitHub Copilot or equivalent) as part of daily delivery, with the judgement to validate their output.
• Demonstrated ability to use AI-assisted development workflows to accelerate delivery, automate repetitive tasks, improve code quality and rapidly validate concepts. Comfortable working within design systems and shared component libraries
• Proven ability to balance technical excellence, user experience and business outcomes when making implementation decisions. Git, CI/CD and collaborative code review workflows

Desirable

• Experience designing Contentful content models
• Experience interpreting designs from Figma and rapidly converting them into working prototypes
• Experience collaborating directly with Product Managers and Designers in discovery and validation activities
• Cloud experience (AWS, Azure)
• Familiarity with ASP.NET Core, C# or similar enterprise web backends
• Working alongside external development or engineering partners
• Automated testing frameworks (unit, integration, E2E, visual regression)
• Understanding of security, privacy and responsible use of AI tools when working with proprietary code, supporter data and confidential information
• Analytics/experimentation tooling
• Agile product delivery

About you

You take ownership from idea to production and enjoy the product conversation as much as the code. You treat AI as a force multiplier for good engineering, never a substitute for it, and you handle confidential information, IP and security with the care a brand of our scale requires.

Our Expectations:

• To embody the club’s BLUE behaviours (Brave, Lead, Unity, Edge) in the approach to work and interaction with others
• To adhere to the club’s policies and procedures, including Health & Safety, Financial Authorisation, Confidentiality and GDPR.
• To act as an ambassador for diversity, equality, and inclusion, and demonstrate a positive commitment by treating others fairly in line with our Equality, Diversity & Inclusion Policy and reporting any acts of discrimination through appropriate channels
• To create a safe environment and act to protect all young people and vulnerable adults that are either in your care or attending club premises, and report any concerns to the Safeguarding Lead
• To report any misconduct or suspected misconduct to the HR Department

Our commitment to Equality, Diversity and Inclusion: 

At Chelsea we recognise that the diversity of our people is one of our greatest strengths and we are taking positive action to ensure our existing colleagues and job applicants can fully be themselves and bring their own unique experiences and perspectives to Chelsea FC. This means giving full and fair consideration to all applicants regardless of age, disability, gender reassignment, race, religion or belief, sex, sexual orientation, marriage and civil partnership, and pregnancy and maternity.   

If you need reasonable adjustments made to the recruitment process, please reach out to your recruiter, who will be able to advise and support you.

Chelsea FC is fully committed to ensuring the safety and well-being of all children, young people and adults at risk (vulnerable groups). We therefore require all successful applicants to complete a DBS Check prior to starting employment. Depending on the role, successful applicants may also be required to undergo other child protection screening where appropriate. 

This is not intended to be exhaustive; the duties and responsibilities may therefore vary over time according to the changing needs of the Club.
