Senior GPU Systems Engineer: Kernel, Runtime & Diagnostics

ByteDance; San Jose (CA); On-site; USD 162,000 - 388,000; Full time

Job summary

ByteDance is seeking a systems software engineer to design and optimize low-level GPU software that keeps modern accelerators usable, observable, and reliable in production. You will work across kernel drivers, runtime components, firmware interfaces, and telemetry to own technically challenging features end-to-end.

Responsibilities include building kernel-driver and host-management components, profiling performance, and collaborating with hardware, compiler, and platform teams to ensure robust,

Qualifications

• Bachelor’s degree in CS, CE, EE, or equivalent practical experience.
• 3+ years of C/C++ low-level or kernel software experience.
• Experience diagnosing failures with traces, logs, profilers, or debuggers.
• Experience delivering production-friendly features across HW and SW teams.

Responsibilities

• Design, implement, and maintain production GPU system software, including kernel-driver, runtime, firmware-interface, host-management components, debugging tracing and profiling tools, and GPU system performance measurement tools
• Own accelerator features from proof of concept and architecture through implementation, pre-silicon or emulation validation, bring-up, qualification, and deployment.
• Debug complex failures involving GPUs, CPUs, memory, PCIe or interconnects, IOMMU, firmware, operating systems, runtimes, and distributed workloads.
• Profile workloads and remove bottlenecks in initialization, memory movement, scheduling, synchronization, communication, recovery, and device utilization.
• Build automated tests, telemetry, dashboards, health checks, and diagnostic tools that make failures reproducible and regressions visible.
• Partner with silicon, firmware, compiler, library, machine‑learning framework, platform, validation, and production teams to deliver compatible system behavior.
• Improve resilience through error detection, isolation, retry, reset, repair, graceful degradation, and clear operational procedures.
• Review low‑level designs and code, document hardware/software contracts, and share practical performance and debugging methods with peers.
