đź“‹ Description
- • As a Networking Operating System Firmware Engineer at OpenAI, you will help bootstrap and scale the switching layer of AI supercomputers by building and maintaining custom NOS images from scratch using open source components like SONiC, SAI, and FRR.
- • Day to day, you will design, implement, test, and debug production NOS software across platform drivers, routing and control-plane state, ASIC programming, observability, and fleet integration, while working with hardware teams to validate ASIC configurations and bring up new switch platforms.
- • You will join OpenAI’s Hardware organization, which develops silicon and system-level solutions for advanced AI workloads, collaborating closely with software and research partners to co-design hardware tightly integrated with AI models.
- • In this role, you will deepen your expertise in networking, NOS internals, switch hardware, and production systems, while driving feature development across software, hardware, and vendor boundaries in ambiguous, open-ended technical challenges.
🎯 Requirements
- • Proven experience working with SONiC or comparable NOS stacks such as FBOSS, Cumulus Linux, Arista EOS, Junos PFE-level integration, or equivalent platform software
- • Strong software engineering fundamentals: clear interfaces, data models, state-machine design, error handling, testing, observability, performance debugging, and maintainable C/C++, Python, Go or Rust code
- • Experience with Linux kernel internals, network device drivers, platform drivers, hwmon, I2C/SMBus, CPLDs, or board-level platform software
- • Experience integrating or debugging Broadcom, Marvell, NVIDIA, Intel, or comparable switch ASIC SDKs and SAI implementations
- • Understanding of L2/L3 forwarding, ECMP, RoCE, BGP, QoS, PFC, buffer tuning, and telemetry
- • Experience with platform bring-up and board-level debugging across thermal, fan, power, transceiver, LED, watchdog, CPLD, or OSFP CMIS flows
🏖️ Benefits
- • Hybrid work model of 3 days in the office per week
- • Relocation assistance to new employees
- • Opportunity to work on cutting-edge AI supercomputing infrastructure at OpenAI
- • Access to collaborate with hardware, software, and research teams on AI-native silicon design
- • Exposure to open source networking stacks and custom design tools that accelerate hardware innovation
- • Support for factory bring-up and qualification through mass deployment of AI systems
