Responsibilities
- Design and implement low-level systems software including kernel interfaces, runtime libraries, networking subsystems, and storage layers.
- Own the architecture of platform systems and evaluate performance, reliability, maintainability, and operational trade-offs.
- Profile and optimize systems to address latency, throughput, and resource-efficiency bottlenecks.
- Build observability infrastructure including service level objectives, dashboards, alerting pipelines, and runbooks.
- Lead root cause analysis for complex systems failures involving concurrency, memory corruption, and kernel-level faults.
- Improve reliability through failure-point reduction, safe rollouts, resiliency testing, overload testing, and fault injection.
- Collaborate with hardware and infrastructure teams to co-design platform software for new compute, memory, and networking capabilities.
- Incorporate privacy, security, and integrity principles into systems designs and platform safeguards.
- Mentor engineers and contribute to recruiting and technical program initiatives.
- Author design documents, facilitate architecture reviews, and communicate technical trade-offs across teams.
Requirements
- Bachelor's degree in Computer Science, Computer Engineering, a relevant technical field, or equivalent practical experience.
- 6+ years of systems software engineering experience involving operating systems, runtime environments, distributed infrastructure, or low-level platform software.
- Experience designing and owning complex systems architecture and evaluating performance, reliability, and operational trade-offs.
- Experience debugging systems-level issues involving memory management, concurrency, kernel interactions, or network stack failures using advanced tooling and instrumentation.
- Experience building and operating production systems at scale, including service level objectives, monitoring, alerting, incident response, and retrospectives.
- Preferred: high-throughput or low-latency optimization experience using profiling tools such as perf, flamegraphs, or hardware performance counters.
- Preferred: kernel development, hypervisor internals, eBPF, open-source systems software, or collaboration with hardware and silicon teams on firmware, drivers, or platform software.
- Preferred: ongoing AI skill development, responsible AI practices, and use of AI tools to improve workflows.
