Full job description

At CGI, we build innovative digital solutions that help organisations transform, improve user experiences and achieve lasting business outcomes. As a Senior Front-End Developer, you'll play a key role in growing our Software Development team across the UK, delivering modern, scalable applications for clients across diverse industries. You'll have the freedom to take ownership of technical solutions, explore creative approaches and influence how we deliver exceptional digital experiences. Working alongside talented colleagues in a collaborative Agile environment, you'll contribute your expertise, mentor others and develop your career within a global organisation that values fresh thinking, continuous learning and meaningful impact.

CGI was recognised in the Sunday Times Best Places to Work List 2025 and has been named a UK ‘Best Employer’ by the Financial Times. We offer a competitive salary, excellent pension, private healthcare, plus a share scheme (3.5% + 3.5% matching) which makes you a CGI Partner not just an employee. We are committed to inclusivity, building a genuinely diverse community of tech talent and inspiring everyone to pursue careers in our sector, including our Armed Forces, and are proud to hold a Gold Award in recognition of our support of the Armed Forces Corporate Covenant. Join us and you’ll be part of an open, friendly community of experts. We’ll train and support you in taking your career wherever you want it to go.

You will need to hold UK Security Clearance or be eligible to go through this clearance. This is a hybrid position.

Your future duties and responsibilities

In this role, you'll take ownership of designing and delivering high-quality, scalable front-end applications that create engaging digital experiences for our clients. Working primarily with React, Angular and TypeScript, you'll apply your technical expertise to develop responsive, accessible and high-performing solutions. You'll collaborate with designers, back-end developers and stakeholders throughout the software development lifecycle, contributing fresh ideas and innovative approaches to complex technical challenges.

As a senior member of our growing Software Development team, you'll help shape technical decisions, champion engineering best practices and support the development of colleagues through mentoring and knowledge sharing. You'll be encouraged to explore emerging technologies, influence delivery approaches and continuously enhance the quality of our solutions, supported by a collaborative team that values your expertise and professional growth.

Key responsibilities:

  • Design & Develop: Build and maintain scalable, responsive web applications using React, Angular, TypeScript and modern JavaScript.
  • Lead & Innovate: Take ownership of front-end technical deliverables, contribute to architectural decisions and introduce creative solutions to development challenges.
  • Collaborate & Deliver: Work closely with UX/UI designers, back-end engineers and stakeholders to create seamless digital experiences.
  • Integrate & Optimise: Connect front-end applications with RESTful APIs, GraphQL services and back-end systems, ensuring performance and reliability.
  • Champion Quality: Promote clean code, automated testing, accessibility standards and continuous performance improvement.
  • Mentor & Support: Share technical knowledge, provide constructive code reviews and coach colleagues to strengthen team capabilities.
  • Adapt & Evolve: Explore additional frameworks, including Next.js, Vue.js and Solid, where appropriate to support client requirements.
  • Drive Agile Delivery: Contribute to sprint planning, retrospectives and continuous improvement activities to deliver high-quality outcomes.

Required qualifications to be successful in this role

To succeed in this role, you'll bring extensive experience in modern front-end development, a passion for building intuitive digital experiences and the confidence to take ownership of technical delivery. You'll combine strong hands-on development expertise with a collaborative mindset, helping teams solve complex challenges while continuously improving engineering practices. Your ability to share knowledge, embrace new technologies and communicate effectively will be key to delivering successful outcomes for our clients.

Essential skills and experience:

  • Front-End Development: significant commercial experience developing modern web applications.
  • React / Angular: Strong hands-on experience with React and/or Angular, alongside TypeScript and JavaScript (ES6+).
  • API Integration: Proven experience integrating front-end applications with RESTful APIs and GraphQL services.
  • Technical Leadership: Ability to take ownership of technical deliverables, influence development decisions and mentor colleagues.
  • Software Engineering: Strong understanding of modern development principles, code quality, testing and performance optimisation.
  • Back-End Integration: Knowledge of integrating applications with technologies such as .NET, Java, Python or Entity Framework.
  • Agile Delivery: Experience working within Agile teams using tools such as Jira, Confluence and Git.
  • Communication & Collaboration: Strong interpersonal skills and the ability to work effectively with cross-functional teams and stakeholders.
Desirable skills and experience:
  • Experience working within an IT consultancy or client-facing environment.
  • Familiarity with cloud platforms including Azure, AWS or Google Cloud.
  • Understanding of CI/CD pipelines and automated testing frameworks.
  • Knowledge of UX/UI principles, responsive design and human-centred design methodologies.
  • Awareness of Web Content Accessibility Guidelines (WCAG).
  • Exposure to additional JavaScript frameworks such as Next.js, Vue.js or Solid.
