Original job description

Decima International is a professional services company, providing project management and controls services to clients in the United States and the Middle East. Our mission is to become the premier professional services provider across all industry sectors we are engaged in. To accomplish this, Decima International’s founders established a simple yet powerful formula:

Approach each client engagement as a partnership, create an environment that attracts the most talented professionals and allows them to flourish, and regulate growth to maintain excellence in our service standards.

If you are interested in a long and rewarding career working with high-profile clients on some of the most challenging projects in the world, then Decima is where you belong. At Decima, you will be able to explore incredible growth and professional development opportunities.

We are seeking a Mechanical Commissioning Engineer to lead the technical commissioning of mechanical systems on data center projects, from design review through Integrated Systems Testing. In this independent, owner-engaged role, you will develop test procedures, direct the field team, assess results against design intent, and report findings to the owner.

The ideal candidate will combine strong data center commissioning expertise with the ability to lead field testing, resolve technical issues, mentor technicians, and communicate findings objectively to owners, designers, contractors, and operators.

RESPONSIBILITIES:

Review mechanical designs, specifications, and submittals against the owner’s project requirements, and identify commissioning concerns before equipment procurement.
Develop commissioning plans, test procedures, and acceptance criteria for chilled water plants, heat rejection equipment, air handling systems, liquid cooling systems, and related equipment.
Witness factory acceptance tests and lead site inspections, pre-functional checks, and Level 4 functional performance testing.
Plan and lead the mechanical scope of Integrated Systems Testing, including cooling failure scenarios, restart sequences, and thermal ride-through under load.
Review sequences of operation and controls integration with the controls engineer.
Analyze test data, resolve technical disputes, and determine whether results meet design requirements and acceptance criteria.
Track deficiencies through closure, report commissioning progress to the owner and project leadership, and prepare test reports.
Lead and mentor commissioning technicians and coordinate activities with contractors, designers, and operators.
Follow site safety procedures and applicable testing and permit requirements.
Maintain accurate and independent reporting in accordance with Decima’s conflict-of-interest and independence policy, without influence from contractors or equipment suppliers.

QUALIFICATIONS

Required Qualifications:

7 to 10 years of commissioning experience on mechanical systems.
At least 5 years of experience on data center projects, including participation in at least one Integrated Systems Test.
Bachelor’s degree in mechanical engineering or a related field, or equivalent experience.
Strong knowledge of chilled water, heat rejection, air handling, pumping systems, and data center cooling design.
Ability to develop test scripts and procedures and interpret mechanical drawings, P&IDs, and sequences of operation.
Strong written and verbal communication skills, including the ability to report technical findings clearly and objectively when they challenge project expectations.
Authorization to work in the United States and ability to pass a background check and drug screen.
Ability to travel 50–75%, work extended site assignments, lift 50 lbs, and wear required personal protective equipment (PPE).

Preferred Qualifications:

Experience with liquid cooling and high-density AI deployments, including coolant distribution units (CDUs), facility water loops, and fluid quality.
Professional certification or license, such as PE, CxA, or CPMP.
Familiarity with ASHRAE Guidelines 0 and 1.1 and Uptime Institute practices.
Experience supporting multiple owner programs or international projects.

POSITION DETAILS:

Primary Location (On-site): Project sites across the United States. Position: Mechanical Commissioning Engineer. Travel: 50–75%, including extended assignments of three weeks or more. Travel, lodging, and per diem are provided per company policy. Site Rotation: Planned before each project; typically, two to three weeks on site and one week off site, subject to project requirements and delays. Working Conditions: Active construction and data center environments, including work at heights, in mechanical and electrical rooms, and in hot or noisy areas. Decima International is an Equal Opportunity Employer that is committed to the safety and well-being of all. All qualified applicants will receive consideration for employment without regard to race, religion, creed, color, national origin, ancestry, sex (including pregnancy, childbirth, breastfeeding, or medical conditions related to pregnancy, childbirth, or breastfeeding), age, medical condition, marital or domestic partner status, sexual orientation, gender, gender identity, gender expression and transgender status, mental disability or physical disability, genetic information, military or veteran status, citizenship, low-income status or any other status or characteristic protected by applicable law.
