Who You Are
You are a highly motivated and methodical software engineer with experience in complex, distributed or mission-critical systems. You are comfortable working across application software, interfaces, test environments and operational infrastructure, and you can translate system-level requirements into practical integration and validation activities.
You demonstrate:
Strong analytical and problem-solving skills, with the ability to investigate complex integration issues and anomalies
A structured and methodical approach to software integration, testing, validation and maintenance
A strong understanding of distributed systems, APIs, asynchronous messaging and operational software
The ability to work across application, infrastructure and system boundaries
A high level of autonomy and responsibility in ensuring software quality, reliability and operational readiness

Participate in the validation of the MCC functions including resource orchestration and planning, control-plane orchestration, component management and control, mission analysis and monitoring
Participate to the testing of the MCC interactions with other Ground Segment components (operational organs and common tools)
Collaborate in building and maintaining representative test environments on containerized Ground Segment infrastructure, including distributed deployments across geographically separated sites
Support scalability and resilience testing, including progressive deployment, gateway and satellite scaling, and recovery from site or component failures
Support cybersecurity verification activities covering authentication integration and confidentiality/integrity of communications, including interfaces
Coordinate defect investigation, change requests and regression testing with software developers, architects, system engineers and external suppliers
Maintain IVV documentation.
Contribute to software packaging, deployment and release validation, ensuring that only required software/services/components are deployed and that COTS and Open Source Software usage remains properly documented
Supervise and manage lifecycle activities from early integration and derisking through deployment, operational qualification, LEOP/IOT support and in-service evolution
Collaborate with contractors and technology providers to ensure technical follow-up (enhancements and licenses updates), delivery quality and compliance with applicable requirements.
Participate to customer demonstrations and formal acceptance activities.
What You’ll Need
Degree in Computer Science, Software Engineering, Electronics, Telecommunications, Aerospace engineering or a related engineering discipline
Proven experience (three years or more) in software integration, verification, validation or testing for complex, distributed or mission-critical systems
Experience with system-level IVV, integration laboratories, test benches or operational software environments
Strong understanding of distributed software architectures, interfaces, APIs, asynchronous messaging and state/stream-based data exchanges
Practical experience with REST APIs and structured message/schema validation
Experience with containerized application environments and distributed deployment architectures; knowledge of container orchestration is highly desirable
Experience with Linux and software scripting/automation for test execution and environment management
Knowledge of configuration management concepts and configuration management driven system implementation

Familiarity with satellite communications, 5G, Software Defined Networking, network control or Ground Segment systems is a strong plus
Knowledge of ECSS-oriented software/product assurance or equivalent quality frameworks is a plus
Experience working with external suppliers and multidisciplinary engineering teams
Fully fluent English written and spoken; French and Spanish are a plus
Strong organisational skills, team player and attention to detail

Where You’ll Work
You will be based in Issy-les-Moulineaux, Paris (France), in a highly technical environment dedicated to IRIS² Ground Segment and Mission Control Centre engineering within the Engineering Department, working closely with software, system, network, infrastructure and operations teams.
The role involves:
Cross-functional collaboration with engineering, IVV, operations, infrastructure and cybersecurity teams
Technical interaction with external software suppliers and Ground Segment partners
Integration and validation activities spanning laboratory, test and operational environments
A dynamic environment combining software engineering, system integration, testing and operational readiness
