Senior Mechanical​/Thermal Engineer

Description

Leidos is seeking a Senior Mechanical/Thermal Engineer to join our Directed Energy team in Albuquerque, New Mexico. The ideal candidate will haveabackground in thermal analysis, engineering design, and thermal controls.

The successful candidate will work with a multidisciplinary team of engineers, scientists, technicians, and fabricators in a research and development environment supporting advanced directed energy technologies, including high‑power microwave, RF, electromagnetic, and pulsed‑power systems.

Please note:This position is located on‑site in Albuquerque, NM. There may be opportunity to telework occasionally.

Primary Responsibilities:

The engineer will be responsible for taking mechanical designs from concept through detailed design, fabrication, assembly, integration, and test. The position requires an individual who can work independently, communicate effectively across technical disciplines, and collaborate closely with machinists, fabricators, vendors, and other engineers to develop robust, manufacturable hardware.

Secondary responsibility for capturing cooling requirements for directed energy systems, developing thermal control systems that satisfy those requirements, supervising their construction, and conducting testing and troubleshooting on cooling equipment to verify performance. Duties may include documenting designs and presenting them to the customers, generating bills of materials and coordinating their purchase, auditing as‑build systems for compliance to design, and documenting test results.

• Create 3D solid models and detailed mechanical designs for innovative hardware, equipment, and systems, carrying designs from initial requirements and concepts through fabrication, assembly, integration, and testing.
• Perform appropriate engineering analysis to support design decisions and verify mechanical performance.
• Create and maintain engineering drawings, including appropriate dimensions, tolerances, and other manufacturing requirements, in accordance with company standards and customer specifications.
• Design hardware with consideration for manufacturability, material selection, machining, welding, fabrication, assembly, and maintenance requirements.
• Work directly with Leidos machinists, fabricators, technicians, and external vendors to develop, procure, and support fabrication of mechanical components and assemblies.
• Resolve design, fabrication, assembly, and testing issues by developing practical and effective mechanical solutions.
• Support hands‑on assembly, integration, troubleshooting, modification, and testing of prototype and experimental hardware.
• Collaborate with engineers and scientists from multiple technical disciplines to develop mechanical interfaces and integrated system solutions.
• Manage multiple engineering tasks and projects while effectively balancing technical requirements, schedules, and priorities.
• Communicate technical concepts, design decisions, and status effectively 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 in accordance with thermal requirements and analysis.
• Develop 3D models, drawings and flow diagrams to document the design of thermal control systems.
