At Northrop Grumman, you’ll have the resources, support, and team to do some of the best work of your career.

We are looking for you to join our team as a Principal/Senior Principal Thermal Analysis Engineer based out of Linthicum, MD.

This position may be filled as a Principal Thermal Analysis Engineer or a Senior Principal Thermal Analysis Engineer.

What You’ll Get to Do:

The thermal design team supports programs across the sector, including the airborne, ground mobile, ground stationery, and surface based naval applications, and across a variety of length scales ranging from ECS systems, sensor and radar systems, chassis, CCAs, and device levels.

• Design advanced electronics thermal management solutions using heat transfer principles to optimize thermal performance
• Perform electronics thermal analysis, requiring experience in heat transfer, including liquid cooled, air-cooled, two-phase flow, and refrigeration thermal solutions for Mission Systems platforms such as airborne, ground based, and naval applications
• Lead thermal designs by owning thermal requirements, thermal architecture, and thermal performance of the design, while mentoring less experienced thermal engineers
• Provide oral and written presentations to internal and external customers and stakeholders

This position is contingent upon the ability to obtain an active US Government Secret Clearance or the successful transfer of an active US Government Secret Clearance prior to start.

Basic Qualifications for a Principal Thermal Analysis Engineer:

Bachelor’s Degree with 5 years of experience, master’s degree with 3 years of experience, Ph.D. with 1 years of experience in Science, Technology, Engineering, Mathematics or related technical fields.

• U.S. citizenship is required.
• Ability to obtain and maintain a US Government Secret security clearance.
• Ability to work onsite daily at the Linthicum, MD (Baltimore area) facility.
• 5+ years of experience in electronics design with emphasis on thermal analysis and optimization of mission‑critical electronics systems (e.g., airborne, ground, or maritime platforms).

• 5+ years of experience applying thermal engineering principles to challenging air cooled, liquid cooled, and conduction cooled hardware in high power density environments.

Basic Qualifications for a Senior Principal Thermal Analysis Engineer:

Bachelor’s Degree with 8 years of experience, master’s degree with 6 years of experience, Ph.D. with 4 years of experience in Science, Technology, Engineering, Mathematics or related technical fields.

• U.S Citizenship is required.
• The ability to obtain/maintain a US Government Secret clearance.
• The ability to work onsite daily at the Linthicum, MD/Baltimore facility.
• 8+ years of experience in electronics design with a primary focus on thermal architecture, analysis, and optimization for defense or other safety/mission‑critical systems.
• 8+ years of experience applying thermal engineering principles to challenging air‑cooled, liquid‑cooled, and conduction‑cooled hardware in high‑power‑density environments.

Preferred Qualifications:

• Active DoD Secret (or higher) security clearance.
• Advanced degree in Mechanical or Aerospace Engineering with a concentration in Heat Transfer and Fluid Dynamics.
• Hands‑on experience (2+ years) with one or more of the following tools: ANSYS Icepak, ANSYS Thermal Desktop, ANSYS Fluent, or similar electronics cooling / thermal analysis codes.
• 2+ years leading the end‑to‑end thermal design of hardware for defense platforms (airborne, ground mobile, ground stationary, or naval), from requirements definition through verification.
• Proven experience advising programs on system‑level thermal trades and collaborating within multidisciplinary teams (systems, mechanical, RF, electrical, reliability) from concept through detailed design.
• 2+ years of experience designing hardware to meet transient thermal conditions
• Experience advancing next‑generation electronics thermal management solutions (e.g., high heat‑flux interfaces, two‑phase or advanced convective cooling, compact high‑power electronics).
• Knowledge of advanced convective and two‑phase thermal management for high heat‑flux / high power‑density applications, including analytical, high‑fidelity numerical, and experimental methods.
• Prior experience leading thermal design at multiple levels of integration (system, chassis, CCA, and microelectronics) for defense or aerospace hardware.
• Experience planning and executing thermal design verification testing, including correlation of analysis to test data and updating models based on results.
