Pay: $77,000–$104,000 per year, based on experience

Job Type: Full-time

Location: Central Ohio – Primarily on-site at customer facilities, with potential travel

Experienced in HVAC, Mechanical Systems, or Commissioning? Ready to Take the Next Step?

TechSite is growing, and we're looking for a Mechanical Commissioning Engineer II who enjoys hands-on technical work, troubleshooting complex systems, and taking ownership of commissioning activities in mission-critical data center environments.

This is an opportunity for someone who has developed a solid foundation in mechanical systems and is ready to take on greater responsibility. You'll independently execute commissioning test procedures, identify and troubleshoot system issues, work directly with contractors and customers, and help guide less-experienced engineers in the field.

We're especially interested in candidates with direct experience performing mechanical functional performance testing and integrated systems testing. However, we also recognize that strong candidates may come from HVAC service, equipment startup, mechanical controls, or other related technical backgrounds.

You don't need to be a senior engineer or have formal management experience. We're looking for someone who understands mechanical systems, can work independently, communicates effectively, and is ready to continue developing their expertise in commissioning.

If you enjoy solving technical problems, working with complex equipment, and seeing projects through from testing to successful completion, we'd like to talk with you.

• Troubleshoot failed test steps and help identify whether issues are related to equipment installation, controls, or testing conditions.
• Coordinate with contractors, vendors, and other technical personnel to address deficiencies and complete testing.

Develop Test Procedures and Document Results

• Review mechanical drawings, equipment specifications, submittals, and Sequences of Operation.
• Assist with developing and updating mechanical commissioning test scripts and checklists.
• Identify potential issues or inconsistencies in system documentation before testing begins.
• Collect and analyze field data, equipment readings, and system trend information.
• Maintain accurate commissioning documentation, including test results, photographs, and deficiency reports.
• Track open issues and coordinate corrective actions through verified resolution.
• Prepare technical reports and documentation for customer review.
• Provide accurate updates on testing progress, outstanding issues, and project completion.

Provide Technical Direction and Support

• Provide day-to-day technical guidance to entry-level commissioning engineers working on assigned projects.
• Assign testing activities, review work, and help ensure procedures are followed correctly.
• Mentor less-experienced engineers in equipment testing, troubleshooting, documentation, and site safety.
• Serve as a technical point of contact for contractors, vendors, and other site personnel.
• Participate in customer commissioning meetings and communicate progress on assigned systems.
• Maintain a safe work environment and follow all site-specific safety requirements.

This position includes technical leadership responsibilities but does not require formal personnel management.

Manage Your Assigned Work and Continue Developing

• Take ownership of assigned commissioning activities from initial setup through testing, documentation, and closeout.

• Monitor progress against project schedules and communicate potential delays or concerns.
• Track time and resources associated with assigned commissioning work.
• Continue developing technical knowledge of mission-critical mechanical systems and commissioning practices.
• Pursue relevant professional development and commissioning certifications.

What We're Looking For

Our ideal candidate has:

• 2–4 years of relevant technical experience, including approximately 1–2 years of direct mechanical commissioning experience, OR 3+ years of closely related experience in HVAC, mechanical controls, equipment startup, test and balance, or mechanical field engineering.
• Hands-on experience with commercial or industrial HVAC and mechanical cooling systems.
• Ability to independently execute mechanical functional performance tests, including setup, testing, troubleshooting, and documentation.
• Familiarity with mechanical systems commonly used in data centers and other mission-critical facilities.
• Working knowledge of BMS/BAS controls and the ability to interpret system operating sequences and trend data.
• Experience using field testing equipment, such as temperature and humidity probes, airflow measurement devices, manometers, and power meters.
• Ability to read and interpret mechanical drawings, specifications, and technical documentation.
• Strong troubleshooting and problem-solving skills.
• Ability to communicate effectively with customers, contractors, vendors, and other engineers.
• Strong organizational skills and attention to detail when documenting technical work.
• Ability to work independently and take responsibility for assigned projects.
• Valid driver's license and ability to meet customer site access and security requirements.

An engineering degree is NOT required. An associate or bachelor's degree in Mechanical Engineering, HVAC technology, or a related technical field is valued, but equivalent hands-on technical experience will be considered.
