MEP Commissioning Agent

About Salas O’Brien/RFS Engineering:

 

Founded in 1975, Salas O’Brien is 5,000 person employee-owned engineering and professional services firm focused on achieving impact for our clients, our team, and the world. We know that tomorrow’s requirements are today’s opportunities, and we are here to design lasting solutions for pressing challenges.

With roots dating to 1957, RFS Engineering (RFS) is a long-standing northeast regional leader providing consulting engineering and commissioning services for the built environment. In late 2025, RFS joined the Salas O’Brien family. 

Salas/RFS project types include college/university, healthcare, laboratory, private secondary school, public K-12 school, data center, commercial, industrial, government, and historic preservation -- all with a focus on sustainable design. 

The Salas/RFS technical expertise is paired with an exceptional team of business development, human resources, finance and accounting, information technology, and marketing professionals, all of whom play a key role in bringing our commitments to life every day.

 

Position Summary:

The MEP Commissioning Agent position will be within the RFS (New England) Division of Salas O’Brien.  The Commissioning Agent will support the planning, execution, and documentation of mechanical, electrical, and plumbing (MEP) systems commissioning for new construction and renovation projects, and for retro-commissioning of MEP systems in existing buildings. The Commissioning Agent will collaborate with owners, design engineers, contractors, equipment vendors and manufacturers, and facilities staff to verify that MEP systems are installed, started, tested, and documented in accordance with the construction documents.

Position Requirements:

  • 10+ years’ field and/or operational experience involving building automation systems (BAS) construction. (Current BAS field technicians looking for a career pivot, while still applying their professional skills, are encouraged to apply.)
  • Bachelor’s or associate degree in engineering or related field (preferred but not required).

Physical Requirements:

  • Regular field presence on active construction sites.
  • Ability to climb ladders, access mechanical rooms, and work around active equipment.

 

Office Assignment:

  • Primary office assignments in Boston, MA, Laconia, NH, or Portland, ME (candidate choice).

 

Travel:

  • Approximately 50% to 75% depending on workflow, primarily day trips to project and client sites.
  • Occasional overnight stays to accommodate project requirements.

 

Compensation and Benefits:

The expected base salary range for this role is 110,000 - $135,000 USD per year. Actual compensation will be determined based on a number of factors including skills, experience, and qualifications.

This role is also eligible for performance-based bonuses and a comprehensive U.S. based benefits package, including:

  • Medical, dental, and vision insurance
  • 401(k) with company match
  • Paid time off and company holidays
  • Wellness programs and employee assistance resources
  • Professional development support
