The role

You will develop low-level embedded software that brings spacecraft hardware to life. The work focuses on hardware abstraction layers, device drivers and hardware interfaces, working with hardware, FPGA and systems engineers.

What you will do

• Design, develop and maintain hardware abstraction layers (HALs), device drivers and board support packages (BSPs).
• Develop and optimize hardware interfaces, peripherals and data transfer mechanisms.
• Lead hands-on board bring-up, hardware/software integration and low-level debugging.
• Write reliable, maintainable C/C++ software for embedded Linux and/or RTOS platforms.
• Diagnose complex issues using hardware documentation, debugging tools and direct hardware testing.
• Develop unit and integration tests to validate software on target hardware.
• Collaborate with hardware, FPGA and systems engineers to deliver robust, flight-ready solutions.

Required qualifications

• 5+ years of professional embedded software development experience in C and/or C++.
• Strong hands-on experience designing and developing HALs and low-level device drivers.
• Experience with BSPs, register-level programming and hardware/peripheral configuration.
• Proven experience with board bring-up, hardware/software integration and low-level debugging.
• Experience with embedded Linux and/or RTOS platforms.
• Understanding of hardware interfaces and protocols such as UART, SPI, I²C, DMA, Ethernet, LVDS or SpaceWire.
• Experience with debugging tools such as GDB, JTAG, logic analyzers or oscilloscopes.
• Ability to read schematics and datasheets and troubleshoot issues across hardware and software.
• Strong problem-solving skills, ownership and ability to work across multidisciplinary teams.

Nice to have

• Linux kernel internals, kernel-space driver development and device trees.
• Embedded Linux build systems such as Yocto or Buildroot.
• ARM-based SoCs and FPGA integration.
• Aerospace, spaceflight or safety-critical software experience.
• Radiation mitigation techniques, including Single Event Upset (SEU) handling.
• Embedded virtualization or hypervisor experience.

Benefits

• 100% company-paid medical, dental and vision for you and your dependents
• 100% company-paid life, AD&D and disability insurance
• Fully paid parental leave: 16 weeks for birthing parents, 10 weeks for non-birthing parents
