Job description

As a Senior Controls Engineer, you will join a leader in veterinary medical device manufacturing, playing a critical role in developing, optimizing, and supporting advanced automation systems that drive manufacturing efficiency, reliability, and innovation. This is your opportunity to design and implement robust control systems, lead large-scale automation projects, and shape the next generation of intelligent, highly automated production equipment.

Why This Role Matters

Manufacturing excellence directly supports IDEXX’s mission to help veterinarians, labs, and pet owners around the world. The automation systems you build and support keep production lines running reliably so our veterinary diagnostic devices reach customers on time and to the highest quality standard. You’ll have the opportunity to shape how the next generation of intelligent, highly automated production equipment is designed and deployed — work that has a visible, lasting impact on the plant floor.

In This Role

• You’ll lead automation controls engineering efforts across production lines and equipment.
• You’ll design, program, test, and optimize PLC- and HMI-based control systems.
• You’ll support machine automation technologies, including motion control, machine vision, industrial robotics, sensors, safety systems, and related control devices.
• You’ll develop control strategies to improve cycle time, reliability, quality, and throughput.
• You’ll write, debug, and implement PLC and HMI applications, primarily in Rockwell Studio 5000 and FactoryTalk platforms.
• Your day-to-day will include developing automation logic, control sequences, interlocks, alarms, and user interfaces.
• You’ll integrate automation equipment with plant-floor systems, including sensors, robots, instrumentation, and data acquisition devices.
• You’ll partner with equipment suppliers, manufacturing engineering, and operations to implement new equipment and upgrades.
• You’ll design control system architectures, control panels, communication networks, and industrial device connectivity.
• You’ll support OT cybersecurity best practices within automation controls environments.
• You’ll lead troubleshooting, root-cause analysis, and support of control systems in live production environments.
• You’ll drive continuous improvement initiatives tied to equipment performance, uptime, and automation maturity.

What You Need To Succeed

• Bachelor’s degree in Electrical Engineering, Controls Engineering, Mechanical Engineering, Computer Engineering, or related discipline—or equivalent experience.
• 7+ years of hands‑on controls engineering experience, including PLC programming, HMI development, and industrial automation support.
• Strong proficiency with Allen‑Bradley PLCs and Rockwell Automation software.
• Solid understanding of industrial control networks and communication protocols (Ethernet/IP, OPC, Modbus, TCP/IP, etc.).
• Experience integrating automation hardware (sensors, actuators, motion control, robotics, drives, etc.).
• Strong analytical and troubleshooting skills with a proven ability to resolve complex automation issues.
• Experience driving projects independently with strong communication and organizational skills.
• Ability to travel up to 5%.
• Preferred:
• Experience with machine vision, robotics, and advanced motion control systems.
• Knowledge of SQL databases, data collection, and basic data integration.
• Familiarity with Python or scripting for automation support tasks.
• Understanding of MES/ERP connectivity or plant‑floor data systems (not required but beneficial).
• Exposure to Industry 4.0 concepts, edge devices, or IIoT connectivity.
• Experience with cloud platforms (AWS, Azure) or modern data tools (Power BI, Tableau) is a plus.
• Understanding of ISA standards such as ISA‑95 or ISA/IEC 62443 (cybersecurity).

What You Can Expect From Us

• $140, 000 - $145, 000 / year, depending on skills and experience.
• Opportunity for annual cash bonus and merit pay increase consideration.
• Health / Dental / Vision benefits from day one.
• 5% matching 401k.
• Paid Time Off.
• Additional benefits including but not limited to financial support, pet insurance, mental health resources, volunteer paid days off, employee stock program, foundation donation matching, and mor.
