Sr Staff OT Systems Engineer (Onsite - Acton)

Job Summary

Join a highly visible global engineering team responsible for connecting advanced manufacturing equipment, industrial control systems, and enterprise technologies across multiple international sites. This role is ideal for experienced OT, automation, controls, industrial networking, and manufacturing systems professionals who enjoy working at the intersection of PLCs, SCADA, industrial data platforms, cybersecurity, and digital manufacturing.

As a technical leader, you'll drive the design and integration of next-generation Operational Technology solutions, helping build secure, scalable, and connected manufacturing environments. You'll partner with Controls Engineering, IT, Cybersecurity, Quality, and Manufacturing teams to solve complex technical challenges, lead global initiatives, and implement technologies such as OPC UA, MQTT, industrial networks, data historians, MES, and cloud-connected manufacturing systems. This position offers the opportunity to influence OT strategy, establish global standards, work with cutting-edge Industry 4.0 technologies, and make a significant impact on manufacturing performance in a highly regulated, world-class manufacturing environment.



Position Overview:

The Sr. Staff OT Systems Engineer will provide technical leadership for the design, implementation, integration, and lifecycle support of Operational Technology systems used in automated manufacturing. This role requires a strong foundation in traditional industrial controls, including PLCs, HMIs, industrial communications, and automated equipment, combined with practical experience supporting distributed OT systems and the infrastructure on which they depend. The team and this role has responsibilities globally including in USA, Malaysia and Costa Rica.

The engineer will work across machine controls, plant-floor systems, industrial networks, servers, databases, data platforms, and manufacturing applications. The role will serve as a technical bridge among Controls Engineering, Manufacturing, IT, Cybersecurity, Quality, equipment suppliers, and system integrators.

The successful candidate will be a hands-on OT engineer who can understand equipment behavior at the PLC and control-system level while also troubleshooting and improving the broader systems that connect, monitor, secure, and support manufacturing operations (databases, supervisory systems, industrial automation software, etc.). The engineer will lead cross-functional projects, establish technical standards, support global manufacturing initiatives, and help deliver OT solutions that are reliable, scalable, secure, maintainable, documented, and appropriately validated.

The Acton MA site is a global business headquarters and product-development site where commercial and business functions, manufacturing, and technical disciplines are co-located. This environment offers broad opportunities to build experience across functions and technologies.

Responsibilities:

• Provide technical leadership for the design, integration, implementation, and lifecycle support of manufacturing OT systems, including HMI and SCADA platforms, industrial networks, data-collection and application servers, databases, and interfaces between manufacturing equipment and plant or enterprise applications.

• Integrate manufacturing equipment into the broader OT environment. Apply working knowledge of PLCs, equipment controls, industrial communications, and machine-level data to define interface requirements and coordinate with controls engineers, equipment suppliers, and system integrators

• Develop and maintain OT system architectures, network diagrams, data-flow diagrams, interface definitions, functional specifications, user requirements, design standards, and supporting engineering documentation.

• Establish standardized and reusable interfaces between manufacturing equipment and higher-level systems, including historians, MES, databases, and other manufacturing applications.

• Design and support industrial data architectures and integrations using technologies such as OPC UA, MQTT, SQL databases, historians, APIs, and managed file transfer.

• Collaborate with IT and Cybersecurity teams to design and support OT networks and infrastructure, including segmentation, switching, routing, firewalls, remote access, servers, virtualization, identity management, backup, patching, monitoring, and recovery.

• Diagnose complex issues spanning equipment controls, communications, infrastructure, software, data flows, and manufacturing applications. Coordinate resolution across Controls Engineering, IT, Cybersecurity, Manufacturing, Quality, suppliers, and system integrators.

• Support the installation, integration, commissioning, qualification, startup, and operational turnover of manufacturing equipment and OT systems, with emphasis on connectivity, data integration, infrastructure readiness, and long-term supportability.
