Job description

We are currently looking for a Flight Software Engineer to join the team in Delft and work on advanced satellite systems.

You will join a team whose work spans mission integration, Earth Observation, secure communications, and space systems engineering. As a Senior Flight Software Engineer, you will design, develop and verify the on-board software that routes and processes data on satellites.

Responsbilities

• You will develop code that integrates several complex interfaces and routes data between them.
• You will design software architecture that optimizes performance within the hardware constraints
• You support systems engineering with the requirement generation and functional flow-down.
• You create unit tests, perform system-level testing, and support hardware-in-the-loop setups to verify software functionality.
• You write clean, maintainable code and produce clear technical documentation to support design reviews and system audits.
• You work closely with other engineering teams to deliver integrated solutions (electrical, mechanical, and systems engineering).

Requirements

• You have at least 10 years of experience in embedded/low level software development.
• You have experience with real-time applications, such as Linux and RTOS.
• You have experience with spacecraft flight software, or comparable vehicle software requiring a high level of reliability.
