Thermofluids Engineer

Working pattern: Full-time, hybrid (3 days onsite on average). Relocation assistance is available.

About the role

As a Thermofluids Engineer within the Global Mechanical Systems Capability function, you will apply Fluids and Thermo-mechanical sub-skills to definition, analysis, validation, and verification activities for integrated power systems, sub-systems, and components. Your work will support AE engine programs in the Defense business, spanning capability acquisition, new product introduction, and in-service product support. You will collaborate within a Project Deployed IPT and with central engineering capability teams, operating in accordance with Rolls-Royce Management System (RRMS) policies and processes.

Responsibilities

• Define requirements for thermo-fluid systems and thermo-mechanical analysis, ensuring accurate flow-down and capture of higher-level requirements for system, sub-system, and component modeling.
• Integrate thermo-fluid systems through cross-functional collaboration to optimize deployment alongside complementary systems and components, working with Project Engineers, Validation and Verification Engineers, and program design and functional chiefs.
• Perform technical analysis of thermo-fluid system functionality, temperature, and thermo-mechanical behavior at whole-engine, sub-system, and component levels using appropriate methods and tools, tailored to each stage of the product lifecycle.
• Conduct verification and validation activities to ensure requirements are met, including test specification, model calibration against measured data, and uncertainty quantification.
• Manage technical approval of thermofluid systems and modeling through certification/qualification, including process compliance, model auditing, and documentation approval within structured review processes.
• Support in-service products through ongoing technical analysis, root-cause analysis, resolution, and modifications as required.

Requirements

• Bachelor’s degree in STEM/Engineering with 1+ years’ experience in thermodynamics, gas dynamics, fluid mechanics, and/or engine design; or
• Master’s degree in STEM/Engineering; or
• PhD in STEM/Engineering.
• Eligibility to obtain and maintain security clearance (USA Citizenship required).

Preferred Qualifications

• Proactive, self-motivated, and customer-focused with the ability to work independently.
• Experience in computer programming languages such as FORTRAN, Visual Basic, and/or C++.
• Experience in heat transfer/thermals modeling and analysis.
• Experience in gas turbine secondary air system, oil system, fuel system, or thermal management system design, modeling, and analysis.
• Experience with Thermofluid Systems analysis tools (SPAN, SC03, AMESim, Simscape, Fluent, STAR-CCM+, NPSS, Simcenter).
• Experience with workflow automation (Preliminary System Design and/or Component Design Systems).
• Experience in gas-turbine engine development, production, overhaul test analysis, and troubleshooting.

Benefits

• Comprehensive Total Rewards package including base pay and discretionary bonus plan.
• Health, dental, vision, disability, life, and accidental death & dismemberment insurance.
• Flexible spending account and health savings account.
• 401(k) retirement savings plan with company match.
• Employee Assistance Program.
• Paid Time Off, holidays, and parental/family care leave.
• Tuition reimbursement.
• Long-term incentive plan (eligibility varies).
