EMBEDDED SOFTWARE ENGINEER, LASER MESH ROUTING (STARLINK)

the company was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today the company is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

We design, build, and operate the largest AI supercomputers in the world, from the ground up. As a member of the Platform Core team, you will be responsible for the lowest layers of the software stack on the devices setting the pace for how fast we can push the frontier of AI. Our team’s software interfaces directly with the core hardware of the supercomputer and its network fabric. **

RESPONSIBILITIES:

• Build and maintain the lean, high-reliability Linux-based operating system that underpins our supercomputer network fabric and Starlink laser mesh of satellites.

• Write (or rewrite) high-performance device drivers to extract the maximum physical capability from our network and compute hardware.

• Manage deployment, operation, and debugging of our platform in production, including:

• Rigorous resolution and root-causing of anomalies to ensure the system is constantly improving in reliability.

• Developing and constantly improving our tools for observability and configuration management.

• Collaborate with our hardware teams and external partners to design the next generation of supercomputer hardware and then bring up our OS and software stack on it.

BASIC QUALIFICATIONS:

• Bachelor’s degree in computer science, engineering, math, or science discipline; OR 2+ years of professional experience in software development in lieu of a degree (internship experience is applicable).

• Hands-on system programming experience in C or C++.

PREFERRED SKILLS AND EXPERIENCE:

• Deep knowledge of the Linux kernel and its networking stack or experience with another production-grade kernel.

• Proficiency with debugging tools spanning kernel, network, and userspace (e.g., ftrace, perf, Wireshark/tcpdump, eBPF, gdb, and more).

• Experience bringing up new hardware from scratch — you have flashed bare-metal software on a microcontroller with JTAG, or bootstrapped a Linux kernel and rootfs on new hardware.

• Demonstrated track record of developing and optimizing device/peripheral drivers ideally for high-speed interfaces, or with advanced considerations like DMA and cache coherency.

• Understanding of major peripheral hardware interface standards (Ethernet, PCIe, I2C, SPI, etc.) — you can critically review a schematic, and debug these interfaces if needed.

• Experience with product security, OS/system hardening, and secure boot schemes.

COMPENSATION AND BENEFITS:

Pay Range:Level 1: $125,000.00 - $165,000.00Level 2: $145,000.00 - $200,000.00
