Senior Thermal Analyst

About the Role

Space is a critical domain, connecting our technologies, our security and our humanity. While others view space as a destination, we see it as a realm of possibilities, where we can innovate, invest, inspire and integrate our capabilities to transform the future.

At Lockheed Martin Space, we aim to harness the full potential of space to cultivate innovation, reduce costs, and push the boundaries of what technology can achieve. We’re creating future‑ready solutions, focusing on resiliency and urgency through our 21st Century Security® vision. We’re erasing boundaries and forming partnerships across industries and around the world. We’re advancing spacecraft and the workforce to fuel the next generation.

And we’re reimagining how space can connect us, ensuring security and prosperity.

Join us in shaping a new era in space and find a career that's built for you.

Senior Mechanical Engineer (Thermal Analysis) – full‑time, supporting the Orion thermal analysis team performing preliminary and detailed level analysis on spacecraft components and subsystems (Avionics, Propulsion, etc.).

Responsibilities include:

• Performing comprehensive modeling on the entire spacecraft thermal system using standardized processes and tools (Thermal Desktop, SINDA/Fluint).
• Providing technical memos and input to data packages to support peer and customer reviews.
• Presenting resultant design and analysis data to the spacecraft design/engineering team, customer technical representatives, and Program Office personnel at technical exchange meetings and formal design reviews.
• Reviewing, interpreting, flowing down, and implementing all program requirements.
• Providing thermal engineering planning and support for multi‑week Thermal Cycle or TVAC and On‑Orbit flight data.
• Working interactively with diverse engineering disciplines in a fast‑paced environment to develop cost‑effective solutions to thermal control requirements that also satisfy producibility objectives defined by Manufacturing and Quality.
• Developing solutions to complex problems that require ingenuity and creativity, working without appreciable direction and exercising considerable latitude in determining technical objectives and approaches to assignments.

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related technical field, with 3+ years of related experience and may have a post‑secondary degree or training in a related discipline.
• Thorough knowledge of heat transfer and thermodynamic principles and their practical engineering application.
• Experience executing engineering design, analysis, and verification across the product development lifecycle.
• Proficiency with CAD and thermal analysis tools (e.g., Creo, Thermal Desktop, ANSYS, or equivalent).
• Apply creative and innovative solutions and resolve anomalous performance issues across any component of the thermal system.
• Excellent technical communication skills, including the ability to document and present analytical results to cross‑functional stakeholders.
• Experience with test planning and execution.

• Hands‑on experience with Thermal Desktop and SINDA/FLUINT.
• Experience using Python for scripting, data analysis, or model automation.
• Familiarity with first‑order heat transfer hand calculations.
• Experience designing spacecraft thermal control systems and hardware.
• Strong analytical skills for design and analysis of spacecraft thermal control subsystems, including the ability to lead investigations of complex thermal issues.
• Engineering and operational experience with spacecraft thermal control subsystem hardware and software.
• Experience with testing thermal hardware in complex systems, both planning and execution or appropriate background and aptitude for skill development.
• Exposure to integration and test (I&T) operations, such as MLI blankets installation and inspection of passive/active thermal control features.
• Ability and willingness to perform technical tasks during non‑standard shifts, including 24/7 Thermal Cycle, TVAC, and launch support, with occasional extended hours.
• Skilled in Microsoft Office (Excel, Word, PowerPoint).
