Job Description
Job Description
We’re excited to connect with candidates in Washington DC; however, this role is based in Atlanta, GA or San Jose, CA. The position offers opportunities for travel and relocation, and we’re seeking candidates who are open to this flexibility. Please note that the role is not based in Washington DC. Monthly per diem and mobilization is on offer.
Lead the Systems That Keep Critical Infrastructure Running At FST Technical Services, we ensure the most complex facilities operate exactly as intended. Our Commissioning division partners with clients across data centers and mission-critical environments to validate that systems are designed, installed, and performing at the highest level.
Why This Role Stands Out
This is not a documentation-driven role.
- Owns system performance from design through execution
- Understands how complex mechanical systems operate as a whole
- Can identify and solve issues before they impact operations
You will work on large-scale, mission-critical data center projects where performance, reliability, and precision are non-negotiable.
What You will Do
Project Leadership & Execution
• Lead commissioning activities across the full lifecycle
• Execute functional testing, witness testing, and system validation
• Manage assignments within schedule, budget, and quality expectations
• Evaluate HVAC, chillers, boilers, pumps, and automation systems
• Troubleshoot system performance issues
• Review design documentation
Client Engagement
• Lead meetings and communicate findings
• Build relationships with clients and contractors
Operational Contributions
• Complete reports and manage time and expenses
Team Development
• Mentor junior engineers and support training
What You Bring
Core Qualifications
• Degree in HVACR, Mechanical, Electrical Engineering or related field
• 7+ years experience or 3+ years commissioning
• Data center experience required
Technical Capabilities
• Experience with HVAC, controls, automation, fire safety systems
• Ability to read construction documents
• Strong communication and problem-solving skills
Physical Requirements
• Ability to work in field environments and lift 30 lbs
Preferred
• EIT, CEM, OSHA 30, BIM experience
Travel Requirements
Travel to project sites as needed based on project demands.
Why FST
At FST, we value execution, accountability, and expertise. Engineers have opportunities to gain experience into leadership roles and work on complex, high-impact projects.
