Thermal R&D Engineer

Thermal R&D Engineer Position Summary AEGIS is seeking a motivated Junior Thermal R&D Engineer to support advanced research and product development in two-phase fluid flow and heat transfer for passive and actively pumped thermal management systems. This role will work closely with senior engineering staff to translate fundamental research into high-performance electronic cooling products, supporting both internal R&D initiatives and collaborative projects with university and national laboratory partners.

This is an excellent opportunity for an early-career thermal/mechanical engineer to develop deep technical expertise in advanced cooling technologies while contributing to real-world product development, experimental research, and customer-facing design work.

Key Responsibilities

Research & Design Support advanced research activities in direct liquid cooling (single/two-phase fluid flow) and heat transfer for passive and actively pumped thermal management systems. Assist in translating fundamental research findings into the development of innovative, high-performance electronic cooling products.

Help evaluate customer application requirements and contribute to physics-based thermal design concepts. Conduct theoretical thermal and mechanical analyses, including design sizing and optimization calculations. CFD Simulation & Analysis Perform multiphase conjugate heat transfer CFD simulations under the guidance of senior engineers; interpret results and help identify effective engineering solutions.

Apply experimental insights to refine and validate CFD models, and support recommendations for design improvements. Experimental Work Participate in the design and execution of heat transfer experiments, including test planning, instrumentation, data acquisition, and uncertainty analysis. Reduce, analyze, and interpret experimental data to validate and improve designs and simulation models.

Collaboration & Communication Collaborate with multidisciplinary engineering teams to solve complex thermal and mechanical design challenges. Support the preparation of technical proposals, marketing materials, and technical publications. Assist in the selection and evaluation of materials and components for advanced cooling systems and products.

Support engagement with academic and research partners under the direction of senior technical staff.

Qualifications

M.S. in Mechanical Engineering, or a closely related field (minimum); Ph.D. preferred. Solid foundation in heat transfer, fluid mechanics, and thermodynamics. Familiarity with CFD and/or FEA software (e.g., ANSYS Fluent or equivalent). Working knowledge of a scripting/analysis tool such as Python/Matlab. Strong analytical, problem-solving, and communication skills.

Ability to work both independently and as part of a collaborative, multidisciplinary team. Preferred: Coursework, thesis, or project experience in two-phase flow, boiling heat transfer, or electronics cooling. Exposure to experimental test setup, instrumentation, or data acquisition systems. Prior internship or research experience in a national lab or university research environment.

Interest in pursuing technical publications and conference presentations.
