This is a senior technical field position—not a formal supervisory or people-management role.

Compensation is based on experience, technical proficiency, BAS knowledge, commissioning and startup capability, certifications, and demonstrated ability to independently execute and lead field assignments.

Position Summary

The Senior BAS Field Installer is responsible for the safe, accurate, and efficient installation, startup, checkout, documentation, and field-level troubleshooting of commercial Building Automation Systems.

The role works closely with Project Management and Applications Engineering and may periodically serve as the senior CMS field representative on smaller projects or defined portions of larger projects.

Core Technical Responsibilities

Independently perform and support commercial BAS field execution, including:

• Install, terminate, configure, label, and check out DDC controllers, control panels, sensors, transmitters, actuators, relays, VFD and equipment interfaces, control wiring, communication networks, and third-party field devices.
• Work from control and mechanical drawings, wiring diagrams, sequences of operation, points lists, submittals, network diagrams, specifications, and other construction documents.
• Perform point-to-point checkout; verify controller power, inputs and outputs, sensors, actuators, equipment enable/disable functions, addressing, communications, and basic controller or device configuration before commissioning.
• Install, verify, and troubleshoot field-level BACnet MS/TP, BACnet/IP, Modbus RTU/TCP, RS-485, controller-to-controller communications, and third-party interfaces, including polarity, termination, addressing, and basic IP architecture.
• Diagnose and resolve field-level wiring, power, I/O, device, communication, addressing, equipment-interface, and installation issues; determine whether problems originate in field installation, mechanical equipment, programming, engineering, networking, or another trade.
• Apply practical knowledge of commercial HVAC systems, including AHUs, RTUs, VAV boxes, fan coils, heat pumps, chillers, boilers, cooling towers, pumps, VFDs, and ventilation systems, to verify controls operation.
• Maintain accurate checkout records, red‑line markups, device labeling, deficiency documentation, and field information needed for as-builts, punch lists, closeout, and turnover.
• Follow approved design, scope, codes, manufacturer requirements, and CMS standards; identify discrepancies, scope gaps, constructability concerns, material shortages, and schedule or labor impacts early.
• Clearly document and elevate advanced programming, engineered design or sequence changes, complex integration or networking, mechanical repair, and potential additional work before proceeding whenever practical.

Field Leadership & Accountability

When assigned, the Senior BAS Field Installer may lead day-to-day field execution on smaller projects or defined portions of larger projects while remaining primarily a senior technical contributor.

• Coordinate field priorities, sequencing, access, materials, routine trade interactions, milestones, checkout, and completion for assigned work.
• Communicate field conditions, quality concerns, scope risks, schedule impacts, labor impacts, and obstacles promptly to the Project Manager or appropriate CMS resource.
• Inspect work, correct field-quality deficiencies, protect installed equipment and customer facilities, minimize rework, and use labor and materials responsibly.
• Provide hands‑on technical guidance to developing installers; demonstrate proper installation and checkout practices, reinforce CMS standards, and share troubleshooting methods.
• Represent CMS Controls professionally and maintain a safe, clean, organized work environment.

Role boundary: Field leadership and technical mentorship do not create formal supervisory authority. Unless specifically authorized, this position does not own employee performance, hiring or discipline, project budgets, contracts, pricing or change orders, customer commercial commitments, engineered design, programming strategy, or overall project management.

Requirements

Required Qualifications

• 5+ years of Building Automation, HVAC Controls, DDC Controls, or closely related field experience.

• Maintain accurate documentation, minimize rework and punch-list items, and use labor and materials responsibly.
