Senior Mechanical/Thermal Engineer

Leidos is hiring a Senior Mechanical/Thermal Engineer to support its Directed Energy team in Albuquerque, NM. In this on-site role, you will own mechanical design work from concept through test, while leading thermal control responsibilities such as cooling requirements, thermal analysis, and verification. Salary range is USD 107,900 - 195,050 per year, with the possibility of occasional telework.

Role focus: build robust mechanical hardware and thermal control systems, quantify heat loads, and support testing and troubleshooting to verify performance for directed energy applications.

Responsibilities

• Take mechanical designs from concept through detailed design, fabrication, assembly, integration, and test.
• Work independently while communicating effectively across technical disciplines and coordinating with machinists, fabricators, vendors, and other engineers.
• Capture cooling requirements for directed energy systems.
• Develop thermal control systems that meet cooling requirements and supervise construction of cooling/thermal control systems.
• Conduct testing and troubleshooting on cooling equipment to verify performance.
• Document designs, present results to customers, and document test results.
• Create bills of materials and coordinate purchases; audit as-built systems for compliance to design.
• Create 3D solid models and detailed mechanical designs for innovative hardware, equipment, and systems, carrying designs from requirements and concepts through fabrication, assembly, integration, and testing.
• Perform engineering analysis to support design decisions and verify mechanical performance.
• Create and maintain engineering drawings, including dimensions, tolerances, and manufacturing requirements aligned with company standards and customer specifications.
• Design for manufacturability, including material selection, machining, welding, fabrication, assembly, and maintenance considerations.
• Collaborate with Leidos machinists, fabricators, technicians, and external vendors to develop, procure, and support mechanical components and assemblies.
• Resolve design, fabrication, assembly, and testing issues by developing practical mechanical solutions.
• Support hands-on assembly, integration, troubleshooting, modification, and testing of prototype and experimental hardware.
• Collaborate with engineers and scientists across technical disciplines to develop mechanical interfaces and integrated system solutions.
• Manage multiple engineering tasks and projects while balancing technical requirements, schedules, and priorities.
• Communicate technical concepts, design decisions, and status to engineering teams, project leadership, customers, and manufacturing personnel.
• Provide technical leadership for significant mechanical subsystems or projects, including establishing mechanical approaches, interfaces, and solutions for complex multidisciplinary problems.
• Collaborate with customers, engineers, and technicians to develop cooling requirements.
• Conduct FEA thermal analysis to quantify heat loads and cooling needs.
• Design cold plates and heat exchangers to manage heat flow.
• Conduct CFD analysis to calculate flow rates, pressure drop, and heat removal; size commercial heat exchangers, fluid pumps, and fans to meet thermal requirements.
• Develop 3D models, drawings, and flow diagrams to document thermal control system designs.

Requirements

• Bachelor’s degree in mechanical engineering or closely related field with 8+ years of experience or a Master’s degree with 6+ years of experience with mechanical or thermal systems.
• US Citizen status required.
• Must meet eligibility to obtain and maintain a Secret Clearance.
• Demonstrated experience developing mechanical hardware from concept through detailed design, fabrication, assembly, integration, and testing.
• Proficiency with SolidWorks, including 3D part and assembly modeling and creation of detailed engineering drawings; experience with PDMWorks.
• Working familiarity with cooling components such as heat exchangers, chillers, pumps, and cooling fans.
• Experience applying mechanical design principles, material selection, tolerancing, and design for manufacturability for fabricated hardware.
• Ability to work independently and collaborate effectively with machinists, fabricators, technicians, engineers, and scientists.
• Experience with thermal measurement diagnostics such as thermocouples, flow gauges, and pressure sensors.
• Strong written and verbal communication skills, including the ability to lead meetings with large groups.
• Demonstrated ability to develop practical solutions to complex mechanical design, fabrication, assembly, and testing problems.
• Ability and willingness to adhere to government and company safety requirements.
• Ability to manage multiple projects or engineering tasks while maintaining schedules and priorities.
• Work location is predominantly Albuquerque, NM; candidate must be a resident of, or willing to relocate to, Albuquerque, NM.
