About The Position

Mainstream Engineering is seeking a Senior Thermal Engineer to develop advanced thermal management technologies for military, government, and commercial applications. This R&D-focused role involves taking ideas from concept through prototype, testing, and production. The engineer may identify technologies, develop proposals, design and build experimental hardware, conduct testing, analyze results, work directly with customers, and support the transition of successful technologies into production. Current applications include thermal systems for hypersonic vehicles, high-power laser systems, and power-dense aerospace platforms, with an emphasis on reducing size, weight, and power while improving system performance. Technologies include microchannel cooling, additively manufactured 3D cooling passages, single-phase pumped fluid loops, vapor-compression and other refrigeration cycles, radiation thermal management, heat exchangers and electronics coldplates, thermal energy storage, oscillating heat pipes, and advanced experimental cooling techniques.

Requirements

Master's or PhD in Mechanical Engineering or Aerospace Engineering.
Minimum GPA of 3.3 for all completed degrees.
At least 10 years of professional engineering experience.
Strong understanding of heat transfer, thermodynamics, and fluid mechanics.
Hands-on laboratory, prototype, or experimental testing experience.
Experience developing thermal systems, components, or technologies.
Ability to independently lead technical projects and solve complex engineering problems.
U.S. citizenship due to ITAR requirements.
