  • Functional, stress, performance, and corner-case testing
• Translate hardware specifications into structured, parameterized test plans
• Guide the team in:
  • Selecting appropriate tools.
  • Defining workload models and parameter configurations
• Establish standards for:
  • Test case definition (parameters, metrics, pass/fail criteria)
  • Result validation and reporting
• Experience with multi-core and parallel programming, including workload scaling and CPU affinity management
• Review Python-based automation, orchestration, and analysis
• Collaborate with hardware, firmware, and system teams to debug issues

Candidate Profile

Essential:

• Strong knowledge of Arm SoC architecture and Linux systems.
• 8+ years of experience in system validation, performance engineering, or low-level systems development.
• Deep understanding of CPU architecture, cache coherency, memory systems (DDR, HBM, NUMA), and high-speed I/O technologies such as PCIe.
• Proven ability to define validation strategies, coverage models, and validation methodologies.
• Hands-on experience using and tuning benchmarking tools such as stress-ng, fio, and iperf.
• Strong Python programming skills for process automation, system coordination, and data examination.
• Experience working with performance analysis software including perf and PMU counters.
• Strong analytical, problem-solving, and ability to collaborate in multi-functional environments.

Desirable:

• Experience working with large-scale or data center systems.
• Strong programming skills in C/C++ and Python for system-level development.
• Previous technical leadership or mentoring experience.
• Experience with scalable validation infrastructure and automation frameworks.
• Knowledge of AI infrastructure or hyperscale compute systems.
