Battery Test & Validation Engineer (High Voltage Packs & Modules)

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.
