Come support the development and engineering support efforts directed at enhancing the Agency's High Performance Computing (HPC) infrastructure, HPC ecosystem, and HPC Storage capabilities as a HPC Test Engineer.
The HPC Test Engineer analyzes system requirements and concept of operations documents, acquisition plans, and system descriptions to develop evaluation and test plans and procedures, prepare for and conduct the data collection and analysis, and report status and results, primarily focused on HPC performance measurement, modeling and analysis, benchmarking, and system optimization/tuning. This position sits at the intersection of several disparate disciplines, including system architecture, test engineering, software development, and data analytics.
- Measure and analyze the performance and scalability of key HPC benchmarks that exercise system components (processor, interconnect, memory, storage, etc.)
- Measure and analyze performance related to platform specific hardware and software, identify bottlenecks and performance tradeoffs, and help tune customer benchmarks.
- Propose remedies to identified bottlenecks via software restructuring and/or architectural improvement with comprehensive understanding of any trade-offs in design, cost, and software engineering effects.
- Investigate/identify performance related issues as they arise and as requested by team leadership
- Prepare timely reports, papers, and presentations describing significant results for dissemination within customer organization.
- Contribute performance-related expertise to cross-team activities that may involve performance tuning of applications, interconnects, and/or storage (I/O).
- Establish best practices for applying lessons learned and optimizations done for a specific system/customer to all future customer engagements.
Eight (8) years experience as a TE in programs and contracts of similar scope, type and complexity is required. Bachelor’s degree in Math, Science, Engineering, Statistics, Engineering Management, or related discipline form an accredited college or university is required. Four (4) years of additional TE experience may be substituted for a bachelor’s degree.
