REQUIRED QUALIFICATIONS - Strong experience with systems programming (such as with Linux, BSD, etc), including meaningful work in the kernel (drivers, core subsystems, or platform enablement) and operating systems. - Professional proficiency in C, C++ for low-level systems development. - Experience building or maintaining core OS services and platform software (system services, daemons, init/service management, device management, logging/telemetry pipelines). - Track record of debugging complex issues across kernel/userspace boundaries using tracing, profiling, and structured root cause analysis. - Familiarity with security fundamentals in OS design: isolation boundaries, privilege separation, secure IPC, attack surface reduction, and vulnerability mitigation practices. STRONGLY PREFERRED - Production experience with Rust in systems contexts (kernel-adjacent tooling, userspace services, security-sensitive components, or performance-critical libraries). - Experience with OS security hardening: SELinux/AppArmor policy, sandboxing, seccomp, namespaces/cgroups, secure boot chains, exploit mitigations. - Experience setting up and operationalizing observability: eBPF-based tooling, perf pipelines, automated regression detection. - Performance and power optimization experience, including measurement methodology (power rails, battery instrumentation, thermal constraints) and closed-loop tuning. - Experience supporting application or UI frameworks at the OS boundary (Wayland/compositors, graphics pipeline performance, input latency, lifecycle/permission models). NICE TO HAVE - Hardware bring-up exposure (bootloader/early boot debugging, device tree/ACPI, board revisions, peripheral enablement), even if not your primary background. - Experience with OTA/update systems, partitioning strategies, rollback/health checks, and update security (signing, provenance). - Experience contributing to upstream open source projects (Linux kernel, system components) and managing long-lived downstream patches responsibly. WHAT SUCCESS LOOKS LIKE - The OS is secure by default, privacy-preserving, and designed for least privilege. - Performance and power characteristics are measurable, repeatable, and continuously improved with low regression rates. - Debugging is fast: tracing, logs, crash artifacts, and metrics make issues diagnosable in development and in the field. - Application and UI teams have stable, well-documented system interfaces that enable high-quality product experiences. WORKING STYLE - You take ownership across boundaries: kernel, services, tooling, and the interfaces that applications rely on. - You are comfortable making careful tradeoffs between security, privacy, performance, power, and developer velocity. - You communicate clearly with partner teams and can translate low-level findings into actionable changes.
