System Software Engineer

OpenAI is looking for a System Software Engineer to design, implement, and debug the foundational software that enables our products. You’ll work across the OS stack—kernel, drivers, and userspace daemons—and own pipelines for building and updating device images. Your work will span performance tuning, security hardening, and deep system debugging.We’re looking for engineers who thrive in complex, cross-disciplinary environments, can take ownership from concept to release, and are passionate about shipping robust, production-grade systems.In this role, you will:Design, implement, and debug kernel modules, device drivers, and userspace daemonsConfigure and maintain the OS: kernel, initramfs, init services, udev rules, networking, and security hardeningBuild and operate image/OTA pipelines (Yocto/Buildroot, package management, A/B updates, dm-verity)Instrument and analyze performance with perf, eBPF, ftrace; optimize CPU, memory, I/O, and power usageOwn system observability and reliability: logging, crash capture, watchdogs, and field diagnosticsCollaborate with hardware, camera/vision, and application teams to define interfaces and deliver featuresEstablish strong engineering practices: code review, CI, reproducible builds, and release managementWork with vendors and support system builds in the factoryYou might thrive in this role if you:Have deep experience shipping Linux-based products on hardware devices (arm64 or x86)Are proficient in C/C++ and comfortable with embedded Linux internals (drivers, IRQs, power management, filesystems, networking)Have strong systems debugging skills with gdb, strace, perf/eBPF, jtag, and kernel logsUnderstand kernel device tree overlays, I2S, I2C, SPI, CSI/DSIAre fluent in userspace foundations: systemd, D-Bus, sockets/IPC, udev, networking tools, shell/PythonHave experience building OS images and packages (Yocto/Buildroot, Debian/RPM, Docker) and OTA updatesBonus points for:Upstream contributions to Linux or major subsystemsExperience with secure boot, platform security, SELinux/AppArmor, TrustZone/OP-TEEGraphics/ISP or accelerator driver exposure (GPU, V4L2, media/codec, DMA, shared memory)Wireless connectivity stack experience (Wi-Fi/BLE, NetworkManager, wpa_supplicant)Production observability at the edge (symbolized crash reports, metrics, remote diagnostics)Experience in robotics, mobile, or other resource-constrained devicesFamiliarity with on-device ML accelerators, audio pipelines (ALSA, DSP, WebRTC, gstreamer)Knowledge of protobuf and other serialization formatsAbout OpenAIOpenAI is an AI research and deployment company dedicated to ensuring that general-purpose artificial intelligence benefits all of humanity.
