Conjugate Heat Transfer Engineer
Quest Defense Systems & Solutions
Role Description Shape the future of innovation as we tackle cutting-edge projects that make a difference. We’re not just in the business of engineering—we’re building a brighter future. Driven by creativity and a culture of excellence, we believe in the power of engineering to solve today’s challenges and create opportunities for tomorrow. What we do matters. If you’re early in your career and want to work on real gas turbine hardware—not just models sitting in a vacuum—this is one of those roles that actually builds your depth fast. Quest Defense Systems & Solutions is supporting advanced turbomachinery and engine programs, and we’re looking for a Conjugate Heat Transfer (CHT) Engineer who can contribute to CFD and aero-thermal analysis across critical engine components. You’ll be working alongside experienced engineers, building models, running analyses, and helping solve real thermal challenges tied directly to hardware performance and reliability. This isn’t a siloed modeling role. You’ll be part of a collaborative team working closely with the customer—translating problems into analysis, identifying risks, and helping drive solutions that matter. - You’ll work on real gas turbine applications, not just theoretical studies - Exposure to full engine and secondary airflow systems, not just isolated components - Direct interaction with customer engineering teams - Opportunity to grow quickly in CFD, CHT, and aero-thermal analysis This role is remote with up to 10% travel.
