R&D Mechanical Engineer

Radiance Technologies, a rapidly growing employee‑owned company, is seeking an R&D Mechanical Engineer to support various ongoing programs within the Scientific and Technical Intelligence Group.

Responsibilities

• Design, develop, and integrate mechanical and thermal systems for circuit‑card mechanical assemblies and supporting technologies.
• Conduct analyses of complex problems using first‑principles methods.
• Contribute to complex engineering projects while working within a multidisciplinary team.
• Produce technical documentation for assigned projects.
• Perform hands‑on work in a laboratory setting with a highly multidisciplinary team.
• Collaborate closely with electrical engineers, computer engineers, and technicians to design, build, and test microelectronics solutions and their physical support systems.
• Execute mechanical and thermal design and analysis, prototype and low‑rate production builds, and failure analysis.

Required Qualifications

• U.S. citizenship with the ability to obtain a security clearance.
• Bachelor’s degree in Mechanical Engineering or a closely related discipline.
• Minimum GPA of 3.2 (out of 4.0) listed on the résumé.
• 2+ years of mechanical engineering experience in a laboratory, R&D, test, prototyping, or experimental environment (a Master’s in Mechanical or Aerospace Engineering can substitute for the experience).
• Self‑motivated and able to work well within a research and development team.
• Hands‑on prototyping experience through events/organizations such as design/build/fly, Formula SAE, CubeSat, or similar.
• Experience with CAD software (e.g., SolidWorks, Fusion 360, CATIA, NX, or similar).
• Proficiency in Geometric Dimensioning and Tolerancing (GD&T), tolerance stack‑ups, and design for manufacturing.
• Experience in heat‑transfer mechanics and thermal systems, preferably in electrical systems.
• Familiarity with standard electrical laboratory equipment (oscilloscopes, function generators, multimeters, power supplies).
• Ability to create engineering drawings, CAD models, bills of materials (BOMs), and fabrication documentation.

Desired Qualifications

• Master’s degree in Mechanical Engineering or a closely related discipline.
• Machine‑shop or hands‑on fabrication experience (lathes, mills, 3D printers, etc.).
• Experience with multiphysics analysis tools such as COMSOL or PLECS.
• Background in high‑voltage engineering, circuit‑card mechanical assemblies, pulsed power, prime power, power electronics, RF, and/or antenna development.
• Experience integrating PCBs, connectors, cabling, thermal components, and mechanical structures.
• Familiarity with VPX, chassis, card guides, cold plates, heat spreaders, or conduction‑cooled electronics.
