Staff Engineer, Thermal Engineering (R6172)

What you'll do:

Required qualifications:

• B.S. in Mechanical Engineering, Aerospace Engineering, or a related discipline.
• Minimum 8 years of professional experience in avionics or electronics thermal engineering, including technical ownership of thermal solutions carried through qualification and into production.
• Expert knowledge of heat transfer (conduction, convection, radiation) and fluid mechanics, with the ability to validate complex models using first-principles calculations.
• Proven experience defining and integrating active and passive cooling solutions at component, subsystem, and system level.
• In-depth knowledge of thermal management design elements, including TIMs, spreaders, heat sinks, cold plates, vapor chambers, heat pipes, and fans, and how they are selected, qualified, and manufactured.
• Advanced proficiency with thermal analysis and CFD tools (e.g., ANSYS Icepak, FloEFD, STAR-CCM+), including setting up, reviewing, and correlating models against test data.
• Experience with CAD design tools such as NX, SolidWorks, or similar, and with PLM-controlled design release.
• Demonstrated experience planning and executing thermal qualification and verification testing, including instrumentation and data acquisition.
• Track record of technical leadership: leading trade studies, presenting at design reviews, and influencing cross-functional design decisions.
• Experience mentoring engineers and reviewing their technical work.
• Excellent written and verbal communication skills, including the ability to communicate technical findings clearly to engineering teams, program leadership, and customers.
• Proven ability to self-direct, prioritize without oversight, and deliver in a fast-paced, startup environment.

Preferred qualifications:

• M.S. in a relevant engineering discipline.
• Experience with high-altitude aircraft avionics cooling and thermal design.
• Experience with aerospace environmental and airworthiness requirements, including MIL-STD-810, MIL-HDBK-310, RTCA DO-160, and MIL-HDBK-516.
• In-depth knowledge of aircraft integration constraints (power, weight, volume, maintainability, safety).
• Knowledge of materials and manufacturing methods relevant to thermal management, including machined, cast, additively manufactured, and bonded thermal hardware.
• Experience with transient and duty-cycle thermal analysis, and with system-level thermal budgets across multiple avionics units.
• Experience with supplier development and technical oversight of thermal hardware suppliers.

Responsibilities

• Serve as technical owner and authority for avionics thermal management across V-BAT, from concept through design, analysis, qualification, and production.
• Define avionics thermal architecture, derive thermal requirements, and establish thermal environments and interface requirements for avionics bays, enclosures, and components.
• Develop, review, and approve analytical, numerical, and computational heat transfer and fluid flow models using hand calculations and CFD tools such as FloEFD. Set modeling standards, assumptions, and margin policies for the team.
• Lead trade studies, system architecture decisions, and risk assessments. Balance thermal performance against power, weight, volume, cost, maintainability, and schedule.
• Define qualification and verification strategy. Lead test planning, instrumentation, and data analysis, and correlate models with test data. Support environmental qualification to standards such as MIL-STD-810 and RTCA DO-160.
• Influence electrical and PCBA design direction early, including component placement, power dissipation budgets, and thermal design rules.
• Author thermal specifications and statements of work. Evaluate suppliers and provide technical direction to them for thermal hardware such as heat sinks, cold plates, heat pipes, vapor chambers, and fans.
• Lead thermal content at design reviews and produce clear, traceable technical reports and analysis records.
• Mentor and develop junior and senior engineers. Review their analyses and test plans and guide cross-disciplinary teams in applying thermal and fluid fundamentals.
• Identify program-level thermal risks early, propose mitigations, and drive them to closure.
