Lead Controls Engineer

Role Overview The Lead Controls Engineer designs and develops the full control system for a next‑generation critical infrastructure product. This role covers closed‑loop control, safety interlocks, alarms/events, HMI, secure communications, energy optimization, and product cybersecurity.

You will work in a structured R&D; product development setting, maturing standardized control architectures from concept through production. Products are manufactured at scale, requiring consistent, version‑controlled software and formal change management. Collaboration spans electrical, mechanical, hydraulic, and embedded engineering.

Key Responsibilities
Design and tune closed‑loop pressure, flow, and temperature control
Define control architecture, sequences of operation, and alarm/event logic
Develop production‑grade embedded control software and firmware
Integrate with building/facility systems using BACnet, Modbus, MQTT
Implement cybersecurity practices, secure updates, and authentication
Build intuitive HMIs with role‑based access
Drive standardization from prototype through production
Define factory test and controls checkout procedures
Lead technical reviews and mentor engineers





Required Qualifications Education & Experience
Bachelor’s degree in Electrical, Controls, Mechatronics, or Computer Engineering
P.Eng designation required
10+ years’ experience developing control systems for industrial, mission‑critical, or HVAC/thermal‑hydraulic products
Experience working in an R&D; or product development setting
Proven closed‑loop control design for pumps, valves, or thermal‑hydraulic systems
Experience with secure device communications and embedded cybersecurity
Background in engineering change management, BOM/drawing release, and configuration control
Experience with chillers, heat pumps, boilers, or variable‑speed pumping is an asset

Technical Skills
Closed‑loop control (pressure, flow, temperature)
HVAC sequences of operation (ASHRAE Guideline 36)
MATLAB/Simulink model‑based design
