Tech Stack
Tag name is followed by "@" symbol and proficiency level value. About proficiency levels:

1-2 — basic awareness. Minimal hands-on experience, and a rudimentary understanding of the technology's purpose;

3-6 — daily use. Comfortable and regular usage, capable of handling common tasks and challenges related to the technology;

7-9 — you are an expert, you can teach others, you know all the pitfalls and tricks;

10 — exceptional knowledge, comprehensive understanding, and adeptness in all aspects of the technology, including advanced problem-solving. Think twice before claiming or demanding such level.

Details

The team builds AI systems and operates with a focus on engineering excellence, hands-on contribution, initiative, communication, and strong prioritization.

Responsibilities

Build and maintain a lean, high-reliability, Linux-based operating system supporting a supercomputer network fabric.
Write or rewrite high-performance device drivers to maximize the capabilities of network and compute hardware.
Manage the deployment, operation, and production debugging of the platform.
Resolve and root-cause anomalies to continuously improve system reliability.
Develop and 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.

Requirements

Hands-on systems programming experience in C or C++.
Strong operating-systems fundamentals, including scheduling, memory management, and I/O.
Understanding of computer networking, including host operating-system stacks and network devices such as switches and routers.
Excellent written and verbal communication skills.

Preferred Skills and Experience

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