Development Operations is seeking a Principal Mechanical Design Engineer to join the Test Systems Engineering (TSE) Family. TSE is responsible for the design of new mechanical, electrical, and physical infrastructure systems required to meet test objectives for research and development of jet engines and component testing within Pratt & Whitney’s Development Operations. The Principal Engineer will contribute to a portfolio of commercial and military programs, as well as capital infrastructure improvement initiatives. This role demands strong proficiency in mechanical design, product definition, and manufacturing to produce engine and rig adaptive systems that simulate aircraft conditions such as engine inlets, exhausts, mounts, liquid and gaseous systems, cooling and heating carts, and overall test stand configuration and construction. Typical project execution includes interpreting project requirements, developing conceptual designs, performing detailed engineering analyses, and producing high‑quality product definition deliverables. Projects must be executed with a strong focus on safety, code compliance, budget, schedule, feasibility, and environmental considerations. The Principal Engineer will also collaborate closely with BOM CIPTs, Test Operations, FCS, and Data Recording departments to ensure smooth STE integration.

The ideal candidate is a proactive, customer‑focused self‑starter who brings strong organizational skills and the confidence to communicate technical concepts to audiences. They will play a key leadership role—guiding teams, ensuring collaboration, and solving complex design issues.

• →Work closely with cross-functional teams Test Operations, CIPTs, and regulatory departments to develop and refine requirements that clearly define the design objectives of Special Test Equipment.
• →Develop complex design solutions independently or while leading multidisciplinary teams of design engineers.
• →Partner closely with civil/structural, electrical, and project engineering teams to deliver practical, cost‑effective solutions that meet program objectives.
• →Openly communicate within and outside of the Test Systems Engineering department to progress STE design and competently discuss and demonstrate the capabilities of the design.
• →Lead and support technical design reviews with stakeholders and chief engineers.
• →Create professionally executed product definition documentation, including drawings and models.
• →Generate assembly documentation and actively lead field verification and validation plans to ensure the equipment’s compliance with design requirements.
• →Provide coaching and mentoring to junior engineers.
• →Incorporate Engineering Standard Work (ESW) into everyday design practices.
• →Support occasional domestic travel (up to 10%) for site coordination and project execution.

• Development Operations provides services to support future products for global commercial airlines, industrial partners and military customers. Services include Assembly, Instrumentation and Test of engines and rigs and the associated facilities, hardware, data systems, software and technology to support this. Development Operations delivers our services in a safe, efficient and sustainable environment.
