**Facilities Mechanical Engineer – Mission-Critical Facilities Design**

Leidos is seeking a driven and detail-oriented Facilities Mechanical Engineer to support the planning, design, and analysis of mechanical systems—primarily Heating, Ventilation, and Air Conditioning (HVAC)—for secure, mission-critical operations. This is a growth-focused role where you’ll work alongside senior engineers to develop high-performance, energy-efficient, and code-compliant systems that support 24/7 operations. You will be expected to provide engineering level support for existing systems and work with other disciplines to resolve site issues.
