Staff Product Performance Engineer

Own the measurement and tracking of product performance, including power, efficiency, and emissions, against the targets defined in the PRD

Identify gaps between measured performance and PRD targets, and drive cross-functional efforts to close them

Design and execute experiments on Linear Generator test units, working hands-on with technicians and the test team to set up, instrument, and run studies

Build and maintain Python-based analysis tools and pipelines to process large test datasets, quantify performance, and identify trends and root causes

Apply first-principles thermodynamic and heat release analysis to explain observed performance

Communicate results clearly to design engineering teams, and make data-driven recommendations that guide design decisions

Develop and improve test methods, instrumentation, and processes to support performance validation on next-generation products

PhD in mechanical engineering, aerospace engineering, chemical engineering, physics, or a related field, or a Master's degree with several years of applicable industry or research experience

Deep expertise in thermodynamics/power generation, with the ability to apply it to real hardware and experimental data

Excellent data analysis skills in Python (e.g., pandas, NumPy, SciPy), including working with large, noisy experimental datasets

Hands-on experience designing and executing experiments involving instrumentation and emissions testing

Strong communicator with a collaborative mindset, comfortable presenting findings to leadership and working across teams

Strong organizational skills and the ability to manage multiple priorities against deadlines
