About the Role

We’re looking for a Senior BAS / Controls Technician who thrives on complex retro-commissioning, logic rebuilding, and BACnet diagnostics. You’ll be the point person for system startups, troubleshooting, and integration across commercial HVAC sites.

If you can tune a PID loop blindfolded and explain BBMD routing in plain English — we want to talk.

Responsibilities

• Perform DDC system startups and retro-commissioning for AHUs, VAVs, and hydronic systems.
• Rebuild and optimize control logic from written sequences of operation.
• Analyze and tune PID loops, reset strategies, and control curves.
• Diagnose BACnet/IP, MSTP, and Modbus communication issues (device bindings, BBMDs, routing).
• Configure trends, alarms, and energy-saving sequences in Niagara or Alerton/Honeywell systems.
• Mentor junior techs on checkout, calibration, and documentation.

Qualifications

• 5–10 years experience in BAS / HVAC Controls.
• Proficiency in Tridium Niagara, Distech, Alerton, or Honeywell.
• Familiar with IP networking, VLAN basics, and switch diagnostics.
• Strong grasp of HVAC mechanical systems, airflow, and energy management principles.
• Able to read schematics, write commissioning reports, and interface with clients.

Lingo & Skills

If the following terms make sense to you — you’re exactly who we’re looking for:

• PID loop tuning
• P2P checkout
• Device binding / I/O mapping
• BBMD / BACnet routing
• Trend and alarm optimization
• VFD commissioning

Why Join Us

You’ll work alongside pros who care about doing things the right way — not the fastest way. Expect challenging projects, excellent pay, and a team that values technical excellence and mutual respect.
