Space Software Architect (m/f/d)

CGI is a European leader in Space Ground Segment systems and services in the domains of Earth Observation, Navigation, Satellite Communications, Space Safety and Mission Operations. We provide critical services and solutions to European & national agencies and institutions, the scientific community, the commercial sector, as well as to the wider public. We are both major contributors to, and act as thought leaders in, a number of key European space initiatives including the Copernicus and Galileo programmes, designing and developing cutting edge solutions for our clients. The European Space market is dynamic, evolving and rapidly growing. CGI is now looking to further expand our business in this area, building on our 50 year successful heritage. We are looking for a Senior Software Architect (m/f/d) to design and shape modern software systems for demanding space applications across Europe. This role combines architecture, technical leadership, and hands-on engineering. You will define end-to-end software architectures for distributed systems with a strong focus on private and hybrid cloud environments. In our context, this is not about assembling standard public cloud services, but about building robust, secure, and maintainable platforms in environments where control, resilience, traceability, and long-term operability matter. You will work on solutions such as cloud-based data lakes and data-sharing platforms for satellite data, as well as backend systems that support processing, distribution, and access to mission-related information. Typical technologies include Kubernetes, OpenStack, Spring Boot, messaging systems, databases, and observability tooling. Cybersecurity is an important part of the role: while security experts define the required measures, you will translate them into sound architecture and design decisions. This is a role for someone who wants real ownership. You will work across the full lifecycle, from requirements engineering and architecture design to documentation, customer communication, implementation support, and validation. You will also contribute to proposals and help shape future solutions before projects even begin.
