Staff Product Performance Engineer

About the role

Responsibilities

• 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

Requirements

• 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
