At RTX, the world largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world’s most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world.

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines and auxiliary power systems and has been revolutionizing modern flight for over 100 years. 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
