Join us and help shape the future of aerospace and defense. Electric Propulsion System Engineers (EPSE) architect, design, and develop game-changing hybrid-electric propulsion system. EPSE engineers work across all CDS subdisciplines to help achieve program objectives of the CDS CIPT. EPSE engineers apply skills from across a wide range of PW Engineering disciplines such as Performance, Operability, Mechanical Disciplines, Aerothermal Management, to develop, integrate and certify subsystems and hardware for Civil and Military customers.  EPSE engineers work the entire system life cycle from 1) control system technology development, 2) interpreting customer requirements, decomposing them to hardware and software, 3) technical and project oversight of hardware implementation, to 4) ensuring control system compliance across engine, flight and customer compliance testing, and finally, 5) leading system and hardware field issue triage and resolution. EPSE engineers work collaboratively with industry partners, including key suppliers and customers, in a team environment, to advance the technology readiness level of emerging hybrid-electric systems and components. EPSE engineers support the concept design definition, system integration, prototype testing and product detail design development, certification and validation, both for systems and components. EPSE engineers support technical proposals, cost estimates, concept trade-off analysis and modeling, in support of advanced hybrid-electric What You Will Do Systems engineering of electric powertrain systems for aerospace electric propulsion. Development of electrical system and subsystem requirements to meet platform level objectives. Modeling of electric powertrain systems at various levels of fidelity to inform designs and processes. Electrical system protections design including protection strategy, analysis of trip curves and selectivity, insulation coordination, and failure analysis. Development of integrated electric system verification and validation plans. Analysis of simulation and test data, presentation and visualization of results for a diverse audience. Coordination with internal and external customers regarding electric propulsion system content in engine trade studies and designs. Potential to serve as Agile Scrum Master, Product Owner, Product Manager, and/or part of the development team  Qualifications You Must Have Bachelor’s degree in Science, Technology, Engineering or Mathematics (STEM) 5 years of engineering experience, or an Advanced Degree and 3 years’ experience.
