Senior Thermal Engineer

Senior Thermal Engineer | Lockheed Martin

The Senior Thermal Engineer will execute thermal-analysis activities for aerospace and defense systems under the guidance of senior thermal leads. This role focuses on developing thermal models, performing steady-state and transient heat-transfer analyses, supporting design decisions for propulsion subsystem, and cooling solutions. In this role your responsibilities will include:

• Thermal Modeling & Analysis
• Build and validate 2-D/3-D thermal FEM models using ANSYS Thermal Desktop
• Conduct steady-state, transient, conductive, convective, and radiative heat-transfer studies.
• Generate temperature, heat-flux, and thermal-gradient plots; calculate margins of safety.

Design Integration

• Work with system and subsystem engineers to incorporate thermal constraints early in the design cycle.
• Provide thermal sizing recommendations for subsystem.

Verification and Validation

• Assist in defining test-article requirements, instrumentation layout, and test-procedure development for thermal ground-test and flight-test campaigns.
• Compare test data to predictions, update models, and document correlation results.

Documentation

• Produce clear analysis reports, design briefs, and risk-mitigation documents following LM standards.
• Maintain configuration-controlled CAE files and analysis templates.

Collaboration & Mentoring

• Participate in multidisciplinary design reviews (DDRs, CDRs) and present findings to senior engineers and program managers.
• Provide technical guidance to junior analysts when needed.

Continuous Improvement

• Stay current with emerging thermal-analysis methods, software releases, and industry standards.
• Contribute to internal best-practice repositories and knowledge-share sessions.

Desired skills:

• Master's degree in a thermal-focused discipline.
• Experience with spacecraft, missile, or hypersonic vehicle thermal environments.
• Knowledge of model-based systems engineering (MBSE) tools (SysML, Cameo).
• Prior involvement in design-to-production or Agile development cycles.
