Apolink is looking to solve the problem of building the world’s most interoperable satellite relay network in low Earth orbit, by developing a reliable and interoperable embedded and flight software stack for their relay spacecraft platforms.
Requirements
- Proficiency in C/C++ for real-time and resource-constrained systems
- Experience with RTOS (FreeRTOS, VxWorks, RTEMS, or similar)
- Strong debugging skills with CI/CD, automated testing, and hardware bring-up
- Hands-on experience with embedded communication protocols (CAN, UART, I²C, SPI, RS-422, etc.)
- Familiarity with spacecraft operations, comm protocols, and avionics integration
- Comfortable working with vendor SDKs and adapting them to flight software needs
- Experience with embedded/flight software development (space, aerospace, or robotics)
Responsibilities
- Architect and implement real-time flight software for satellite command and control
- Develop embedded software for avionics, SDRs, and optical/RF payload subsystems
- Build hardware abstraction layers, device drivers, and telemetry/telecommand interfaces
- Read and integrate vendor SDKs into the flight stack for bus and payload components
- Implement autonomy features, including fault detection, isolation, and recovery (FDIR)
- Build and maintain software-in-the-loop (SIL) and hardware-in-the-loop (HITL) frameworks
- Design spacecraft-to-ground communication protocols with authentication and security
Other
- B.S. in Computer Science, Computer Engineering, Electrical Engineering, or related field
- 5+ years of experience in embedded/flight software development (space, aerospace, or robotics)
- Ability to work in-person or willingness to relocate to Palo Alto, CA
- Must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State
- Passion for building reliable systems that operate in extreme environments
