Full job description

At CGI, you will play a key role in shaping intuitive, high-performing digital experiences that deliver real value to clients and end users. As a React Developer, you will contribute to building scalable front-end solutions that support business transformation and innovation across industries. Working within a collaborative and forward-thinking environment, you will have the opportunity to take ownership of your work, contribute creative ideas, and help deliver impactful outcomes. CGI empowers you to grow your expertise, work with modern technologies, and make a meaningful difference while being supported by a strong, inclusive team culture.

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.

Due to the secure nature of the programme, you will need to hold UK Security Clearance or be eligible to go through this clearance. Our teams operate within a flexible hybrid working model, however on-site requirements vary by project, so the ability to travel as required to meet client needs is essential. Initially the majority of this work will need 1/2 days a week on site in Glasgow.

Your future duties and responsibilities

In this role, you will design, build, and enhance modern web applications using React, contributing directly to solutions that drive client success. You will take ownership of key features and components, working closely with designers, backend engineers, and product teams to translate requirements into scalable, high-quality code. You will be encouraged to deepen your technical expertise, share knowledge, and continuously improve development standards while contributing ideas that shape how solutions are delivered.

You will play an important role in balancing delivery and technical development, taking responsibility for your work while being supported in progressing toward more senior responsibilities.

Develop responsive, scalable applications using React.js
Build reusable components and front-end libraries
Collaborate within cross-functional agile teams
Integrate front-end solutions with APIs and backend services
Improve application performance, accessibility, and usability
Review code quality through peer reviews and best practices
Troubleshoot technical issues effectively
Learn modern tools, frameworks, and approaches

Required qualifications to be successful in this role

You will bring hands-on experience in React development and modern JavaScript, with the ability to deliver high-quality front-end solutions. You should be comfortable taking ownership of your work while continuing to grow your technical depth within a collaborative team environment.

You should have commercial experience developing applications using React.js
Strong proficiency in JavaScript (ES6+) and core front-end principles
Experience with HTML5, CSS3, and responsive design techniques
Familiarity with RESTful APIs and integration patterns
Proven ability to write clean, maintainable, and testable code
Experience using Git and modern development workflows
Understanding of debugging, performance optimisation, and best practices
Ability to collaborate effectively and contribute to continuous improvement
