We are seeking a highly skilled and motivated Embedded Software Engineer to join our satellite payload team. You will be responsible for designing, implementing, and optimizing embedded software for advanced satellite payloads, with a strong emphasis on performance, reliability, and real-time constraints. The ideal candidate thrives in fast-paced environments and is passionate about pushing the boundaries of space technology

KEY RESPONSIBILITIES / KEY RESULT AREAS

• Develop and maintain embedded software for satellite payload systems using Rust and C++.
• Collaborate with systems engineers, hardware designers, and mission teams to define software requirements and interfaces.
• Optimize code for real-time performance, low power consumption, and fault tolerance.
• Integrate software with hardware components and conduct hardware-in-the-loop (HIL) testing.
• Participate in code reviews, unit testing, and continuous integration workflows.
• Troubleshoot and resolve issues across the software-hardware boundary.
• Contribute to documentation, including design specifications, test plans, and operational procedures.
