Senior BAS Field Engineer | Commissioning | Startup | Controls

Top-tier Building Automation talent is in high demand and we’re looking for someone who wants more than just service tickets.

We’re hiring an experienced BAS Field Engineer who can take ownership of system startup, commissioning, and final turnover on commercial HVAC automation projects. If you’re the person others call when systems won’t integrate, sequences don’t perform, or startups are behind schedule this role is built for you.

This is not a junior technician position. We need a field leader who can walk onto a jobsite, diagnose issues quickly, communicate confidently with contractors and end users, and deliver systems that perform on day one.

What You’ll Own:

  • Full BAS checkout, startup, and commissioning
  • Advanced troubleshooting (DDC, controls networks, low/medium voltage)
  • Sequence validation and performance optimization
  • Client training and turnover documentation
  • Field problem-solving that keeps projects on schedule
  • Direct collaboration with PMs, sales engineers, electricians, and mechanical contractors

Qualifications:

  • Four (4) + years in BAS / HVAC Controls field work
  • Experience commissioning commercial systems
  • Ability to operate independently in the field
  • Experience with DDC systems (Tridium, Niagara, Distech, JCI, Siemens, Honeywell, etc. a plus)

Why make the move?

  • High autonomy
  • Complex, technical projects (not simply service only work)
  • Competitive compensation for proven performers
  • Continued opportunities for career advancement

If you’re currently doing startup/commissioning work but feel underutilized or capped, this is the upgrade you’ve been seeking.

Company provides: Competitive compensation, Company vehicle, Medical, Dental, and Vision insurance, Disability coverage, 401(k), Paid Time Off (PTO), stable work environment with long-term career growth, additional incentives and professional development opportunities

Key Words: (HVAC, Building Automation, Controls, Niagara, JACE, Johnson Controls, BAS, DDC, BAC, BAU, Direct Digital Controls, MRI, LON, Lon Works, BACnet, MODbus, Johnson Controls, ATC Controls, Automatic Temperature Controls, Invensys, Metasys, Niagara AX, Building Automation Graphics, EBI, Symmetre, EMS, BMS, temperature controls)
