Senior C++ Engineer - Satellite Real-Time Control Systems

The role

You will develop and operate real-time embedded software for a SAR satellite constellation. This includes writing modern C++ code, building software layers for sensors and actuators, and driving quality through the full development lifecycle.

What you will do

• Write and optimize modern C++ code for on-orbit execution
• Build and own the software layer bridging sensors, actuators, and control algorithms
• Drive quality across the full development lifecycle from requirements to on-orbit support
• Collaborate with GNC, electronics, ground segment, and mission operations engineers
• Lead architecture evolution through refactoring and optimization
• Investigate anomalies by deep-diving into flight telemetry and rolling out fixes

Required qualifications

• Strong experience writing modern C++ with a clear understanding of production-quality code
• Proven track record of delivering real-time control software for autonomous or safety-critical systems such as satellites, drones, robotics, or automotive systems
• Solid understanding of hard real-time constraints, latency budgeting, and deterministic behaviour
• Experience interfacing with sensors and actuators in embedded Linux environments
• Strong engineering practices including rigorous testing, CI/CD, and clear documentation
• Ownership mindset across the full software lifecycle from concept to on-orbit maintenance
• Clear communicator who collaborates effectively across multidisciplinary teams

Nice to have

• Experience with hardware-in-the-loop and model-in-the-loop testing
• Experience supporting software in operational or mission-critical environments
• Familiarity with satellite GNC or space systems

Before you apply

• Employment is subject to applicable security screening (incl. SUPO, where required)
• Talent Attraction screening
• Hiring Manager interview
• Task and Technical interview
• On-site technical workshop and behavioural interview
