Software Engineer, Supercomputer Network (Starlink)

SpaceX•Redmond, WA

23h

About The Position

As a member of SpaceX’s Platform Core team, the Software Engineer will build and maintain low-level software for the company’s AI supercomputers and network fabric, including the Starlink laser mesh of satellites. The role interfaces directly with supercomputer hardware and its network fabric, helping determine how quickly the platform can advance AI capabilities. The position involves developing a lean, high-reliability Linux-based operating system, writing or rewriting high-performance device drivers, and deploying, operating, and debugging the platform in production. The engineer will investigate anomalies, improve system reliability, develop observability and configuration-management tools, and collaborate with hardware teams and external partners to design and bring up software on next-generation hardware.

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 from scratch, 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 of developing and optimizing device or peripheral drivers, ideally for high-speed interfaces or with considerations such as DMA and cache coherency.
Understanding of peripheral hardware interface standards such as Ethernet, PCIe, I2C, and SPI, and ability to review schematics and debug these interfaces.
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 satellite laser mesh.
Write or rewrite high-performance device drivers to maximize the capabilities of network and compute hardware.
Manage platform deployment, operation, and debugging in production.
Resolve and identify the root causes of anomalies to continuously improve system reliability.
Develop and continuously improve observability and configuration-management tools.
Collaborate with hardware teams and external partners to design next-generation supercomputer hardware and bring up the operating system and software stack on it.
