Imagine working at the forefront of innovation in fluid-flow technology, with over 1,400 colleagues across the globe and eight manufacturing facilities on four continents. Armstrong Fluid Technology is a community of the brightest and most creative minds, driven by a shared mission to engineer the future and safeguard our planet.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 standardsWhat We’re Looking ForEducation 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 solid assetTechnical 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 verificationSoft 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.Why Armstrong Fluid Technology?By joining us, you’ll become part of a global community pushing the boundaries of fluid-flow technology while upholding Armstrong’s commitment to sustainability. Together, we’ll build tomorrow’s solutions today.#J-18808-Ljbffr
