Senior Mechanical Commissioning Project Engineer

$130k - $150k

FST Technical Services

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. 

 
We are seeking a Senior Mechanical Project Engineer who brings deep technical expertise, field leadership, and the ability to drive outcomes in high-performance environments. 

Why This Role Stands Out 

This is not a documentation-driven role. 

 
This is a position for someone who: 

  • 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 

 
Technical Expertise & Problem Solving 
• 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 

 
Professional Skills 
• 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. 

Important Notes 

No visa sponsorship available. Candidates must be authorized to work in the United States. 

Salary range: $130,000 to $150,000

FST Technical does not offer employment-based visa sponsorship for this position. Applicants must be legally authorized to work in the United States without the need for employer sponsorship now or in the future.
