MJI Energy is looking for a skilled Building Automation Systems (BAS) Technician to join our growing team. In this role you'll install, program, commission, and maintain building automation systems for commercial properties across the New York Metro area. This is hands-on, technically demanding work at a modern BAS company built on 30+ years of real mechanical expertise — and one of the best opportunities in the region for a controls technician who wants to do more than just maintain legacy systems.

- Integrate mechanical and electrical systems using BACnet, Modbus, and other industry-standard protocols
- Conduct system startup, commissioning, and functional performance testing
- Develop and maintain accurate as-built documentation, sequences of operations, and system schematics
- Provide on-site client training on BAS platform operation and monitoring dashboards
- Collaborate with project managers, mechanical teams, and fellow technicians on active installations
What We're Looking For
- 2+ years of hands-on experience in building automation, DDC controls, or HVAC controls
- Working knowledge of Niagara Framework / Tridium or comparable BAS platforms
- Familiarity with BACnet, Modbus, or other BAS communication protocols
- Ability to read and interpret mechanical, electrical, and control drawings
- Strong troubleshooting and problem-solving skills
- Valid driver's license and reliable transportation
- Ability to work independently and manage activity across multiple job sites
- Professional communication skills for direct client interaction
Nice to Have
Not required — but these will make you stand out.
- Johnson Controls platform experience (Metasys, FX series, or similar)
- Niagara N4 Certification
- Experience with energy management or demand-response systems
- Commercial HVAC mechanical background
What We Offer
- Competitive salary commensurate with experience
- Profit sharing — the people building MJI Energy benefit from MJI Energy's growth
- Health benefits
- Company vehicle or mileage reimbursement for field travel
- Ongoing training and certification support (Niagara, Johnson Controls)
- Direct growth path in a company that is actively expanding
