In this role, you will design and develop the complete control system at the heart of a next-generation critical infrastructure product - serving one of the fastest-growing and most demanding applications in our industry. The scope spans the full controls stack: closed-loop pressure and temperature control, state management and safety interlocks, alarm and event management, HMI, secure communications, energy-efficient operation, and product cybersecurity.
This is a standardized product development role, not a one-off project role. Our products are manufactured at scale, so control systems must behave consistently across every unit - released as version-controlled software baselines with standard configurations and formal change control. You will help mature products from concept through production, working alongside electrical, mechanical, hydraulic, and embedded software engineers.
Key Accountabilities
- Controls
- Design and implement closed-loop control strategies for fluid systems - such as pump/flow control and temperature control
- Architect system control topology
- Design the alarm, event, and parameter framework
- Implement secure communications and integration with building/facility management systems and customer equipment, using standard industrial protocols.
- Optimize control strategies for energy efficiency and equipment performance
- Embedded
- Develop control software as a standard, repeatable product
- Provide ongoing firmware support as units are deployed in the field.
- Security
- Embed cybersecurity best practices into the product, including secure firmware update processes, certificate-based authentication, and alignment with recognized industry security frameworks.
- HMI
- Develop an intuitive HMI for commissioning, diagnostics, manual overrides, and standalone operation, with role-based access control.
- Standardization & Release
- Mature the design through proof-of-concept, pre-production, and production phases, incorporating lessons learned while protecting the standard architecture.
- Define controls checkout and factory test procedures so that every production unit is verified consistently.
- Collaborate with electrical, mechanical, hydraulic, and embedded software teams, and represent controls design in technical reviews.
- Provide technical leadership, mentor engineers, and set controls design standards
What We're Looking For
Education and Experience
- Bachelor's degree in electrical, Controls, Mechatronics, or Computer Engineering;
- Eng designation is required.
- Minimum 10 years of experience developing control systems for industrial or mission-critical products (thermal, hydraulic, or rotating equipment)
- Proven experience designing and tuning closed-loop control for pumps, valves, or thermal-hydraulic systems
- Experience implementing secure device communications and embedded product cybersecurity practices.
- Demonstrated experience with engineering change management, BOM and drawing release, and configuration control within a formal product development lifecycle.
- Critical infrastructure, mission-critical, or HVAC controls product experience - including chillers, heat pumps, boilers, or variable-speed pumping - is a strong asset
Technical Skills
- Controls
- Closed-loop control design and tuning for pressure, flow, and temperature
- Sequences of operation for HVAC systems, including ASHRAE Guideline 36
- Model-based control design and simulation (MATLAB/Simulink)
- Redundant sensor handling and fault management
- Embedded
- Embedded controller and PLC development
- Embedded programming in C/C++ and IEC 61131-3
- Firmware lifecycle: version control, upgrade procedures, and compatibility matrices
- HMI
- HMI design and development for commissioning, diagnostics, and operation
- Communications & Security
- Secure device communications and integration using standard building/industrial protocols (BACnet, Modbus, MQTT)
- Alignment with recognized cybersecurity standards, including IEC 62443
- Event logging, telemetry, and remote diagnostics design
- Standards & Verification
- HVAC energy and efficiency standards, including ASHRAE 90.1
- Product safety and regulatory compliance (UL/CSA 60730, EMC)
- Hardware-in-the-loop (HIL) testing and control system verification
Soft Skills
- Ability to simplify complex problems and provide clear, well-reasoned recommendations.
- A product mindset - designing for repeatability, reliability, and scale, with the discipline to follow standard documentation and release processes.
- An ability to communicate openly and authentically in all situations.
