Embedded Software Engineer

Loft Orbital builds and operates reliable, shareable satellites for customers seeking faster access to orbit. As an Embedded Software Engineer, you will develop low-level software that brings spacecraft hardware to life, focusing on hardware abstraction layers, device drivers, and hardware interfaces while collaborating with hardware, FPGA, and systems engineers to integrate and debug complex electronics.

• 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

• 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 Space Wire
• 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

• 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
