Embedded Software Engineer, Laser Mesh Routing (Starlink)

SpaceX•Palo Alto, CA

About The Position

As a member of SpaceX’s Platform Core team, the Embedded Software Engineer will work on the lowest layers of the software stack for devices supporting the Starlink laser mesh and supercomputer network fabric. The role involves building and maintaining a lean, highly reliable Linux-based operating system, developing high-performance device drivers, and operating and debugging the platform in production. The engineer will also work with hardware teams and external partners to design next-generation hardware and bring up the OS and software stack on it.

Requirements

Bachelor’s degree in computer science, engineering, math, or a science discipline, or at least 2 years of professional software-development experience in lieu of a degree; internship experience is applicable.
Hands-on system programming experience in C or C++.

Nice To Haves

Deep knowledge of the Linux kernel and its networking stack, or experience with another production-grade kernel.
Proficiency with debugging tools across kernel, network, and userspace, such as ftrace, perf, Wireshark/tcpdump, eBPF, and gdb.
Experience bringing up new hardware, such as flashing bare-metal software on a microcontroller with JTAG or bootstrapping a Linux kernel and root filesystem on new hardware.
A demonstrated track record developing and optimizing device or peripheral drivers, ideally for high-speed interfaces or with advanced considerations such as DMA and cache coherency.
Understanding of major peripheral hardware interface standards, including Ethernet, PCIe, I2C, and SPI; ability to critically review schematics and debug these interfaces as needed.
Experience with product security, operating-system or system hardening, and secure boot schemes.

Responsibilities

Build and maintain a lean, high-reliability Linux-based operating system for the supercomputer network fabric and Starlink laser mesh.
Write or rewrite high-performance device drivers to maximize the capabilities of network and compute hardware.
Manage deployment, operation, and debugging of the platform in production.
Resolve and root-cause anomalies to continually improve system reliability.
Develop and improve observability and configuration-management tools.
Collaborate with hardware teams and external partners to design next-generation hardware and bring up the operating system and software stack on it.
