Building Automation Engineer (BACnet/Modbus/PLC)

Building Automation Engineer (BACnet / Modbus / PLC)

Uriel Management — Dallas/Fort Worth, TX (Hybrid)

Full-time | $95,000 – $135,000 per year, based on experience

AI is coming to building controls, and we're the ones putting it in the building. Uriel Management is a technology company bringing AI-driven control to commercial buildings across Texas, backed by a 45-year HVAC and controls contractor. You'll work on real equipment in real buildings, not demos.

We need an engineer who can walk into a site running Trane Tracer, Niagara, Metasys, Distech, or a no-name gateway, get it talking to our AI over BACnet or Modbus, write the control sequence, and commission it.

Why you'll want this job

• You own the whole problem. From getting a device to show up on the bus, to the sequence running and proven on a trend, it's yours end to end. Nobody hands you a spec and walks away.
• New equipment every week, not the same building for three years. A dozen BAS brands, hundreds of sites, every gateway ever made. If you like the puzzle, you'll never run out.
• Small team, direct line to the CTO. Your integration goes live the week you finish it. No ticket queue, no six layers of review.
• Top-of-market pay: $95,000 – $135,000 plus performance bonus. We pay for engineers who can actually make the network talk.
• Code counts here. Python, protocols, and PLC logic in the same role, a combination that makes you more valuable everywhere you go next.
• Controls meets AI. You'll work where control sequences and machine learning overlap, a skill set almost nobody in this industry has yet.
• Remote most days, DFW site visits when the panel needs eyes. No forty hours a week of windshield time.
• 45 years of HVAC and controls behind you. Real customers, real equipment, real problems worth solving.

What you'll do

• Integrate our systems with existing building automation platforms at customer sites over BACnet/IP, BACnet MSTP, Modbus TCP, and Modbus RTU
• Write, test, and commission control sequences for HVAC and building equipment; tune loops and validate points end to end
• Configure and program PLCs, DDC controllers, and gateways; build device drivers and point maps for equipment we haven't seen before
• Script integrations and tools in Python (or similar) against controller and vendor APIs
• Diagnose communication faults remotely and on site: device discovery, addressing, termination, register maps, trend and alarm review
• Build and support demand response sequences: load-shed and setpoint strategies, event execution, and verification from trend data
• Work directly with our CTO on integration work and with field techs on installs; produce control narratives, point lists, and as-builts

You must have

• 3+ years programming and commissioning PLCs or DDC controllers, and you can name the platforms and tools you used
• Hands-on BACnet, both IP and MSTP, including troubleshooting discovery and addressing problems
• Hands-on Modbus, both TCP and RTU, including register mapping and byte-order problems
• Working code in at least one general-purpose language (Python preferred; C/C++, C#, or JavaScript fine), plus Structured Text or Ladder
• Commissioning experience: point-to-point checkout, loop tuning, FAT/SAT, sequence validation
• Familiar with AI: you use AI tools daily for code, docs, and troubleshooting, and you understand how machine learning models consume and act on building data
• Willingness to be on site in DFW as needed; most work is remote

Nice to have

• Trane Tracer SC+ / Ensemble energy management systems; Niagara N4 certification; Distech, JCI Metasys, Siemens Desigo, or Honeywell experience
• Allen-Bradley Studio 5000 or Siemens TIA Portal
• MQTT, OPC UA, REST APIs, Linux, SQL
• Demand response or utility program experience
• Applied machine learning or data analysis in Python (pandas, scikit-learn, time-series forecasting)
• Experience supporting controls across many sites rather than one large building

Pay & benefits

• $95,000 – $135,000 per year, based on experience
• Performance bonus
• Health, dental, and vision insurance
• Paid time off and paid holidays
• Additional benefits package
• Hybrid: remote most days, DFW site visits when a job needs eyes on the panel
