Packaging Mechanical Engineer Radiant is seeking a Packaging Mechanical Engineer to own packaging and integration of turbomachinery and electrical systems from requirements capture through operation lifecycle.This role is crucial for ensuring the nuclear microreactor meets structural and safety requirements while optimizing for cost, efficiency, manufacturability, and serviceabiilty. You'll join a dynamic team focusing on the design and development of power conversion and electrical systems converting heat generated from a nuclear reactor to clean, abundant electricity for customers. This role requires strong communication and collaboration skills to work effectively with various teams within engineering, manufacturing, and validation. You'll play an instrumental role in building Earth's first mass-produced nuclear reactors. Responsibilities and Duties: Contribute to the strategy and packaging of the Powertrain System to meet structural and safety requirements. Apply communication and negotiation skills to facilitate discussions between hardware engineering teams. Use attention to detail in GD&T analyses and installation drawings to convey assembly intent. Promote the use of CAD methods and standard processes within the Powertrain department. Define and complete necessary hardware integration verification activities, including CAE, physical mockups, and hardware testing. Required Skills and Qualifications: BS in Mechanical or Aerospace Engineering. 2+ years of experience in integrating, designing, and/or building mechanical and electrical systems. Strong capabilities in 3DX/CATIA/NX/Solidworks for the development of mechanical designs and prototypes. Experience in integration and packaging of electrical power plants, eVTOL, EVs and complicated high voltage electrical systems. Desired Skills and Qualifications: Demonstrated strong mechanical engineering fundamentals across a broad range of topics. Design packaging of electrical systems into an aircraft, EV, spacecraft, gas turbine, microturbine, Wind Turbine or nuclear reactor. Experience drafting, piping, and updating instrumentation schematics. Experience creating drawings like P&IDs, ICDs, and GADs for electrical systems, cooling loops, seal gas systems, and related rotating equipment. Additional Requirements: Must be willing to work extended hours and weekends as necessary to achieve company goals.
