[Remote] Conjugate Heat Transfer Engineer

Note: The job is a remote job and is open to candidates in USA. Quest Defense Systems & Solutions is supporting advanced turbomachinery and engine programs, and they’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 to build models, run analyses, and solve real thermal challenges tied directly to hardware performance and reliability.ResponsibilitiesUse computational tools to perform thermal and/or CFD analysis for gas turbine components and turbomachineryLead the effort in development of geometry and mesh for analysis models along with the necessary model setup and analysis of those modelsPost-process and prepare high-quality presentations of resultsPrepare and present reports on findings on formal technical reviewsCreate, support and maintain secondary airflow system models and whole engine modelsDevelop and participate in root cause and/or risk failure mode and error analysis (FMEA) for gas turbine enginesSupport test and fielded hardware verification and validation effortsSkillsThe successful candidate is detail oriented and highly collaborative. There will be a significant amount of interaction with the customer's teams.
