Systems Engineer – Space Systems

Position Description
At CGI, we're helping shape the future of the UK space industry, delivering innovative systems engineering solutions that support critical space programmes and strengthen national capabilities. As a Systems Engineer within our Space business, you'll contribute to complex, mission-critical projects, applying systems thinking and cutting-edge technologies to deliver secure, resilient and high-performing solutions. You'll take ownership of meaningful engineering challenges, bring creative ideas to life and collaborate with multidisciplinary experts to solve complex problems. Supported by CGI's extensive space and technology expertise, collaborative culture and commitment to professional development, you'll have the opportunity to influence technical decisions, expand your capabilities and make a lasting impact on the future of space systems and services.

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. This is a hybrid position, based in Leatherhead, Reading or London.

Your future duties and responsibilities
In this role, you will help design, develop and assure complex systems supporting CGI's Space business, contributing to programmes where reliability, security and operational performance are essential. Working across the full systems engineering lifecycle, you'll translate business, mission and operational requirements into robust technical solutions, from early concept development and systems architecture through to integration, verification and validation.
You'll collaborate with experienced engineers, technical specialists and clients to tackle challenging engineering problems, explore innovative approaches and improve the delivery of complex space-related capabilities. Whether applying Model-Based Systems Engineering (MBSE), developing system architectures or supporting critical technical decisions, you'll have the opportunity to influence outcomes and take ownership of your contributions. You'll be supported by a collaborative environment that encourages knowledge sharing, continuous learning and career progression.

Key responsibilities include:
• Design & Deliver: Apply systems engineering principles throughout the lifecycle, supporting the development of secure, reliable and resilient space systems and associated technologies.
• Analyse & Define: Capture, analyse and manage system, mission and operational requirements, ensuring alignment with stakeholder needs and programme objectives.
• Model & Architect: Develop system models and architectures using MBSE methodologies, digital engineering tools and recognised frameworks.
• Integrate & Validate: Support system integration, verification and validation (V&V), ensuring solutions meet technical, operational and performance requirements.
• Innovate & Optimise: Explore opportunities to improve engineering processes, adopt digital technologies and enhance system performance and efficiency.
• Collaborate & Influence: Work closely with multidisciplinary teams, clients and stakeholders to resolve technical challenges and inform architectural and engineering decisions.
• Assure & Improve: Support technical assurance, risk management and continuous improvement across complex systems and programmes.
• Lead & Develop: For senior-level appointments, provide technical leadership, mentor engineers, guide engineering approaches and contribute to future business opportunities.

• Digital Technologies: Understanding of how systems engineering can be applied within digital environments, including cloud platforms, IT architecture or DevOps.
• Stakeholder Engagement: Strong communication and stakeholder management skills, with the ability to engage and influence technical and non-technical audiences.
• Problem-Solving: Ability to apply systems thinking to complex technical challenges involving evolving requirements and competing priorities.
Desirable experience and qualifications:
• Previous experience working on space systems, satellite technologies, ground systems or space-related programmes.
• Knowledge of capability planning, enterprise design or operational analysis.
• Experience applying artificial intelligence, automation or emerging digital engineering technologies.
• Professional engineering registration, such as Chartered Engineer (CEng) or Incorporated Engineer (IEng).
• Experience supporting cybersecurity, system safety or technical assurance activities.
• Additional qualifications or experience in project management, business analysis or change management.
