Embedded Software Engineer

Wanna join the adventure?Loft Orbital is making space simple. We build and operate reliable, shareable satellites that give customers a faster, simpler path to orbit. By combining flight-proven spacecraft platforms with our own hardware and software, we make it easier to deploy missions in space. As an Embedded Software Engineer, you'll develop the low-level software that brings our spacecraft hardware to life.

You'll focus on hardware abstraction layers (HALs), device drivers, and hardware interfaces, working closely with hardware, FPGA , and systems engineers to integrate and debug complex electronics.

This role is ideal for an engineer who enjoys digging into the details, solving problems at the hardware/software boundary, and seeing their code fly in space. ## About this role - 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. ## Must Haves - 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 Haves - 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. ## Some of Our Awesome Benefits - 100% company-paid medical, dental, and vision insurance option for employees and dependents - Flexible Spending (FSA) and Health Savings (HSA) Accounts offered with an employer contribution to the HSA - 100% employer paid Life, AD&D, Short-Term, and Long-Term Disability insurance - Flexible Time Off policy for vacation and sick leave, and 12 paid holidays - 401(k) plan and equity options - Daily catered lunches and snacks - International exposure to our team in France - Fully paid parental leave; 14 weeks for primary caregiver and 10 weeks for secondary caregiver - Carrot Fertility provides comprehensive, inclusive fertility healthcare and family-forming benefits with financial support - Off-sites and many social events and celebrations - Relocation assistance when applicable * Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications.

At Loft, we value respectful debate and people who aren’t afraid to challenge assumptions. We strongly encourage you to apply, even if you don’t check all the boxes. ## Who We Are Loft: Space Made Simple. Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.

We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months.

With more than 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives. With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.
