Battery Test & Validation Engineer

At Heart Aerospace we develop the ES-30, a regional hybrid-electric airplane with a capacity of 30 passengers, an electric zero-emission range of 200 km and an extended hybrid range of 400 km. Heart is targeting type certification of the ES-30 by the end of the decade. Your mission Heart Aerospace is seeking a highly motivated and experienced Battery Test & Validation Engineer to join our growing and dynamic team. In this role, you will be a key contributor to the development, testing, and optimization of advanced battery cells specifically designed for the demanding requirements of electric aerospace applications. You will leverage your deep understanding of Test & Validation methodologies and approach to drive innovation and ensure the highest levels of performance, safety and reliability. Key responsibilities include but are not limited to: • Lead the development and execution of comprehensive test plans and procedures for battery modules and high voltage battery packs designed for aerospace applications. • Collaborate closely with the design team to define DFMEA, test requirements and ensure testability of new battery technologies and designs. Support the development of battery system qualification and certification plans. • Create and maintain system and sub-system Design Verification Plans and Reports (DVP&R). Draft and release test plans. Host Test Readiness Reviews. • Execute hands on testing for performance, life cycle, environmental, safety, mechanical (shock and vibe), thermal, electrical and homologation testing. • Design, build and integrate test fixtures, data acquisition systems, and control software to conduct accurate and repeatable testing. • Analyze test data, generate detailed reports, and present findings to cross-functional teams and leadership. • Identify failure modes, perform root cause analysis to enhance battery system performance and reliability. • Manage external testing labs and vendors as needed. You'll Bring These Qualifications for Senior Battery Test & Validation Engineer: • 5+ years of experience in battery testing and validation in high-reliability industries. • Understanding of battery electrochemistry, performance characteristics, and safety requirements for lithium-ion batteries. • Direct hands on experience in high voltage battery system testing and validation for lithium-ion batteries. • Experience running battery testing equipment (e.g., cyclers, environmental chambers, safety test equipment) and data acquisition systems. • Proficiency in data acquisition and analysis tools (e.g., LabVIEW, MATLAB). • Strong problem-solving skills and the ability to perform root cause analysis. • Familiarity with high-voltage systems and safety protocols. You'll Bring These Qualifications for Staff Battery Test & Validation Engineer: • 8+ years of experience in battery testing and validation, preferably within the aerospace, automotive, or other high-reliability industries. • Deep understanding of battery electrochemistry, performance characteristics, failure mechanisms, and safety requirements for lithium-ion batteries. • Direct hands on experience in high voltage battery system testing and validation for lithium-ion batteries. • Experience running battery testing equipment (e.g., cyclers, environmental chambers, safety test equipment) and data acquisition systems. • Proficiency in data acquisition and analysis tools (e.g., LabVIEW, MATLAB). • Strong problem-solving skills and the ability to perform root cause analysis. • Highly efficiency with high-voltage systems and safety protocols. These Qualifications Would Be Nice to Have: • Familiarity with aerospace industry standards, regulatory requirements, qualification and certification processes. • Experience with battery modeling and simulation. • Knowledge of battery management systems (BMS) and control algorithms. Education • M.S. or Ph.D. in Chemical Engineering, Materials Science, Electrochemistry, or a related field. Base Pay Range: $140,000 — $216,000 USD
