BuildMEP’s take: Why these roles now?
At BuildMEP, we sit between MEP practice, controls, and procurement, and we see hiring signals every week. The roles leading automation engineering careers 2025 are:
- Industrial Controls (PLC–SCADA)
- Automation Project Engineer / Systems Integrator
- Robotics & Mechatronics (incl. RPA)
- AI/ML for Manufacturing & Utilities
- Building Automation (BAS/BMS)
They win because plants and buildings are chasing uptime, quality, and energy savings with OPC UA interoperability, IEC 61131-3 PLC stacks, BACnet/Modbus, and ISA/IEC 62443 security now considered “table stakes.”
BuildMEP note: If you’re already strong in MEP/HVAC, Controls and BAS/BMS are your fastest on-ramps.
1) Industrial Automation / Controls Engineer (PLC–SCADA)

Publish a project playbook repo with templates for URS/FDS, I/O list, FAT/SAT checklist, and a risk register.
3) Robotics & Mechatronics Engineer (incl. RPA)
What you’ll do
Specify, program, and deploy robot arms/cobots, AMRs/AGVs, vision, and flexible cells; or automate digital drudge work with RPA where it fits the plant.
Day-one toolkit
- Robot programming (FANUC/ABB/UR), path planning, safety
- Vision & sensors, kinematics, end-effectors
- PLC/fieldbus basics; OPC UA/SCADA handshakes to MES/quality
Certs worth having
OEM robot and vision credentials.
BuildMEP portfolio idea
URSim pick-and-place or vision defect-detector sim with cycle-time and OEE notes.
4) AI & Machine Learning Specialist (Manufacturing/Quality)
What you’ll do
Build models for visual inspection, predictive maintenance, anomaly detection, and energy optimization in plants and utilities.
Day-one toolkit
- Python, pipelines, time-series from historians/MES
- MLOps at the edge (containerized inference, drift monitoring)
- Integration with PLC/SCADA via OPC UA information models
Certs worth having
Cloud ML badges (AWS/GCP/Azure), domain courses in industrial AI.
BuildMEP portfolio idea
Edge-deployable anomaly detector for a pump/fan with confusion matrix, drift chart, and simple CMMS integration note.
5) Building Automation Engineer (BAS/BMS)
What you’ll do
Deliver smarter HVAC, lighting, metering—with analytics and AI-assisted optimization for comfort, efficiency, and grid readiness.
Day-one toolkit
- Protocols: BACnet/IP, Modbus, MQTT
- Supervisory platforms; KPI dashboards for IEQ, energy, FDD
- OT security hygiene (62443 mindset, patching, segmentation)
Certs worth having
Vendor BAS credentials (Siemens/Schneider/Johnson), energy auditing add-ons.
BuildMEP portfolio idea
BACnet trend logging with a live kW/ton widget and IAQ alarms—document sequence of operation and point list.
Bonus career: OT/ICS Cybersecurity
Every plant and building now needs defenders with process safety + network security instincts. Start with asset inventory, zones/conduits, remote-access MFA, backup/restore testing, and patch strategy—aligned to ISA/IEC 62443.
Skills & Standards recruiters keep listing
- IEC 61131-3 PLC languages (Ladder/FBD/ST)
- OPC UA (IEC 62541) for interoperable plant/building data
- Industrial networking + safety (SIL/PL)
- Basic ISA/IEC 62443 cybersecurity practices
- Recognized certs: ISA CCST/CAP, vendor PLC/robot/BAS, cloud ML
90-Day Break-In Plan (BuildMEP template)
First month: Days 1–30 — Foundations
- Rebuild core Ladder/FBD/ST skills; finish 2 mini PLC projects
- Add OPC UA publish → dashboard demo (trends + alarms)
- Draft a 1-page zones & conduits risk checklist (62443 mindset)
Secomd month: Days 31–60 — Portfolio
- Ship one micro-project: URSim pick-place or BACnet/IP trend logger with an energy KPI

FAQs
Q1: What’s the fastest on-ramp for MEP engineers?
BAS/BMS or Controls—your HVAC sequencing and commissioning experience transfers immediately.
Q2: Is AI/ML realistic without a CS degree?
Yes. Start with Python + time-series, build one vision or vibration demo, and earn one cloud ML badge.
Q3: What portfolio wins interviews?
A repo showing PLC → OPC UA → dashboard, plus either a robotics sim or BAS KPI demo—2 minutes of screen-recorded proof.
Q4: Do I need cybersecurity if I’m not a security engineer?
Basic 62443 hygiene is now expected: backups, segmentation, access control, and a patch cadence.
Q5: CCST first or vendor PLC first?
For broad recognizability, do CCST; if you’re targeting a vendor-specific shop, start with their PLC badge.
