Battery Testing Engineer

Role As a Test Engineer at SES, you’ll turn complex questions into meaningful data. This role blends mechanical and electrical engineering fundamentals with hands‑on testing and system operation in a dynamic, industrial laboratory environment. You’ll plan and execute custom tests, design fixtures and methods, instrument hardware, collect high quality data, and transform results into clear, actionable insights. Battery projects span testing and analysis of cells, modules, and packs in diverse applications across various sectors, focused on proving whether a system performs as expected. Key Responsibilities Develop custom and specialized test plans, fixtures, and test methods. Execute tests safely and efficiently while monitoring live data. Collect, analyze, and document high quality test data. Interpret results and produce clear, concise technical reports. What Success Looks Like Successful Test Engineers at SES are adaptable problem solvers who thrive in both independent and collaborative environments. You’re hands‑on, mechanically curious, and comfortable working with electrical, mechanical, and chemical systems. You can safely navigate a heavy industrial lab setting, juggle competing priorities, and keep projects moving forward—even when tests don’t go as planned. Strong communication skills are essential, as you routinely interact with teammates and clients, translating technical details into clear verbal explanations and well‑written test methods and reports. A Day in the Life Morning discussions refine test concepts or identify instrumentation and risk considerations. You may review drawings, finalize a test plan, or troubleshoot unexpected challenges. In the lab you instrument hardware, coordinate with technicians, monitor live data, and adapt on the fly—sometimes pushing systems to their limits to uncover critical insights. Safety, schedule, and performance are balanced while managing real‑time risk. The day ends with tangible progress: data collected, questions answered, and a complex test successfully executed. Basic Qualifications BS in Mechanical Engineering with 3–5 years of experience in testing or manufacturing/industrial equipment operations. Experience with electrical/mechanical testing methods and instrumentation. Hands‑on aptitude and comfort working with physical systems. Experience with data acquisition and test control systems. Ability to conceptualize and develop test methods, fixtures, and equipment with attention to accuracy and repeatability. Strong technical writing and communication skills. Highly motivated, self‑starter with strong critical thinking and problem‑solving abilities. Familiarity with statistical techniques for reliability, capability analysis, regression, ANOVA, and sample size justification (plus). Experience with CAD software (SolidWorks or similar). Professional Engineer license or willingness to obtain one. U.S. citizenship required; ability to obtain a U.S. government security clearance. Preferred Qualifications MS in Engineering or more than 5 years of relevant experience. Knowledge of material properties and failure mechanisms for metals and polymers under mechanical, thermal, electrical, and environmental loading. Experience with electrochemistry and battery energy storage fundamentals. Experience developing test plans and reports suitable for verification, validation, and compliance documentation. Experience validating test methods for repeatability and reproducibility. Familiarity with hazard and risk assessment tools such as FMEA or fault tree analysis. Experience with battery safety standards and regulations (e.g., UL, IEC, UN, SAE). Experience or familiarity with numerical simulation methods such as finite element or computational fluid dynamics analysis. Benefits Competitive compensation aligned with experience and market benchmarks. Medical, dental, and vision coverage. Paid time off and paid holidays. A collaborative, inclusive, and technically challenging environment. High autonomy, high impact technical work. Direct influence on real‑world safety and performance. Collaboration with world‑recognized subject matter experts. Supportive, entrepreneurial, employee‑owned culture. Thought leadership, shaping the field.
