Job Description
Position Description
The Space, Defence and Intelligence business unit in CGI is a true IT Systems Integrator. We work, build, and operate bespoke, technically complex, mission-critical systems which help our clients keep us all safe and secure. We bring innovation to our clients using proven and emerging technologies, agile delivery processes and our deep expertise across the breadth of space, defence, intelligence, aerospace and maritime, all underpinned by our end-to-end cyber capability. We work collaboratively with global technology companies, cutting edge SMEs and academia to deliver the optimal solution for each client.
CGI was recognised in the Sunday Times Best Places to Work List 2026 and has been named one of the ‘World’s Best Employers’ by Forbes magazine. 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. This position will be a hybrid position, working out of our site in Leatherhead.
Your future duties and responsibilities
Are you a self-motivated front-end engineer with a passion for transforming complex scientific and engineering data into engaging, user-friendly interfaces? CGI’s Secure Space Systems business is expanding rapidly, and we’re looking for an experienced JavaScript developer to join our innovative team. You’ll be working on projects that range from early-stage prototyping to full-scale agile developments—solving challenging problems in Space Situational Awareness, Space Domain Awareness, and Command & Control.
What You’ll Do:
• Develop Engaging Interfaces: Create efficient, high-quality user experiences using JavaScript, TypeScript, CSS, and HTML5.
• Collaborate Across Teams: Work closely with cross-functional teams in dynamic, agile environments (Scrum, SAFe, and DevSecOps) to rapidly adapt to evolving requirements.
• Present Complex Data: Transform intricate scientific and engineering data into intuitive, visually appealing interfaces that empower users.
• Innovate in a Fast-Paced Environment: Engage with diverse projects, learn new technologies, and contribute to cutting-edge solutions in the space sector.
Required Qualifications To Be Successful In This Role
• Technical Expertise: Strong experience in JavaScript, TypeScript, CSS, and HTML5.
• Teamwork & Communication: Excellent collaboration and communication skills to thrive in a dynamic, agile setting where priorities can shift quickly.
• Adaptability: A pragmatic, delivery-focused mindset with a love for learning and adapting to new challenges.
Highly Desirable Skills:
• Angular & Bootstrap: Experience with Angular 12+ and Bootstrap, as well as a strong grasp of the modern JavaScript development tool chain.
• Back-End Exposure: Experience in Java is highly desirable.
Additional Assets:
• UX Design Systems: Familiarity with the Astro Space UX Design System.
• Agile Development: Previous exposure to Agile methodologies or similar technologies (training provided if necessary).
• Advanced Technologies: Knowledge of big data technologies (HBase, Hadoop), machine learning frameworks (Spark), or orbit dynamics is of interest.
Why CGI Secure Space Systems?
Join a team that’s at the forefront of space technology innovation. At CGI, you’ll have the opportunity to work on pioneering projects in a collaborative, fast-paced environment where your skills will directly impact the future of space situational and domain awareness. We’re committed to fostering professional growth and innovation, and we’re looking for talented individuals who are eager to make a difference.
Together, as owners, let’s turn meaningful insights into action.
Life at CGI is rooted in ownership, teamwork, respect and belonging. Here, you’ll reach your full potential because…
You are invited to be an owner from day 1 as we work together to bring our Dream to life. That’s why we call ourselves CGI Partners rather than employees. We benefit from our collective success and actively shape our company’s strategy and direction.
Your work creates value. You’ll develop innovative solutions and build relationships with teammates and clients while accessing global capabilities to scale your ideas, embrace new opportunities, and benefit from expansive industry and technology expertise.
You’ll shape your career by joining a company built to grow and last. You’ll be supported by leaders who care about your health and well-being and provide you with opportunities to deepen your skills and broaden your horizons.
