Staff Embedded Software Engineer

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll collaborate across teams shape decisions and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand and your voice will help define the stories were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Interplanetary Sciences Program was establishedto expand access to scientific exploration across our solar system. Its mission is to make planetary research faster more affordable and more capable than ever before by rethinking how science missions are designed built andoperated. The program aims to enable scientists to send instruments to distant worlds without decades of development or prohibitive costs. By creating a sustainable model for interplanetary exploration we are transforming space science from an occasional event into a continuous process of discovery that accelerates knowledge broadens participation and inspires the next generation of explorers.

About the Role:

• Own the complete storage platform software stack for a space-based data center: custom Linux kernel drivers OpenZFS pool design NFS data serving and automated fault recovery shipping a platform that preserves up to a petabyte of mission data through years of radiation exposure
• Design and implement custom Linux kernel drivers for NVMe fault recovery and GPIO overcurrent protection working across PCI/PCIe block layer and interrupt subsystems to detect and recover from radiation-induced upsets without data loss
• Lead the ZFS pool topology architectural decisions by building quantitative reliability models that balance upset probability resilver risk and capacity over a 6 year mission then validate through fault injection testing
• Develop the integration layer between NVMe controller reset and ZFS ensuring that a drive recovering from a transient fault re-enters the storage pool cleanly bridging driver-level recovery with filesystem-level fault tolerance
• Rapidly prototype on commodity hardware from first boot through sustained 10 Gbps writes with automated fault recovery de-risking the architecture before committing to the target platform then carry the design through integration and launch

About You:

• 5 years writing Linux kernel code actual driver development involving PCI/PCIe devices block storage or interrupt-driven hardware with meaningful time spent in kernel space
• Experience withstorage systems: ZFS or othercopy-on-writefilesystems RAIDNVMeinternals or high-throughput network storage (e.g. NFS)
• Depth in one or more: filesystem internals block layer / device management or storage protocol implementation
• Strong working knowledge of OS internals: virtual memory interrupt context constraints synchronization primitives and I/O stack behavior

Nice to haves but not required:

• Hands-on experienceatthedriverhardware software boundary: DMA coherency MMIO semantics PCIe enumeration and cache behavior
• Strong working knowledge ofdata structures and systems reasoningfor storage (Merkle treesNVMesubmission/completion queue ring buffershash tables radix trees)
• Experiencetestingstorage systems including fault injection (PCIe/NVMeresets error storms) low-level tracing (ftrace/perf/bpftrace)andcrash dump analysis (kdump/vmcore)
• Experiencedesigningsoftware recovery aroundstorage hardwarefault cases whether thats storage firmware autonomous vehicle data systems large-scale distributed infrastructure or embedded platforms
• Familiarity with embedded Linux build systems (Yocto or Buildroot) and cross-compilation
• Hardware lab comfort: serial consoles logic analyzers and willingness to debug PCIe enumeration failures on a prototype board alongside theelectrical engineers
