Key job responsibilities
EtherCAT Network Architecture & Topology
Define and maintain the OneMHS EtherCAT controls architecture, including topology, ring and cable-redundancy design, segmentation, and device-order rules
Develop architecture diagrams, and network topology drawings, and establish network design limits such as device counts per segment, cycle-time and latency budgets, and safety-connection capacity
Define addressing, naming, and identification standards for devices, ports, and cables
Establish network diagnostics, fault isolation, and troubleshooting practices for operations and maintenance teams
Device Selection, Qualification & Component Standards
Select, specify, and qualify controls hardware for the architecture, including industrial PCs, couplers, I/O, MDR controllers, VFDs, IO-Link masters and devices, safety devices, scanners, sensors, and controls power supplies
Own the approved component list, including exact part numbers, firmware/hardware revisions, and device profiles
Evaluate new and alternate components for technical fit, compliance (e.g., UL, Class 2/LVLE), cost, availability, and lifecycle risk
Partner with suppliers on technical requirements, certification status, product roadmaps, and obsolescence management
Develop substitution and change-approval criteria for vendors and integration partners
Functional Safety Integration
Define the integration of safety devices and safety-over-fieldbus (e.g., FSoE) into the controls architecture
Establish safety-controller allocation, safety-zone, and E-stop integration rules in coordination with Safety and Controls teams
Support compliance with applicable functional safety standards (e.g., ISO 13849, IEC 62061)
Hardware Development, Prototyping & Validation
Build and maintain test benches and lab environments to validate devices, topologies, and failure modes
Lead prototype testing, interoperability testing, and production-readiness validation of new hardware and architectures
Support factory acceptance testing, site acceptance testing, and commissioning of controls hardware
OneMHS Program Specifications
Author and maintain controls architecture specifications, device integration requirements, and cabling standards
Define vendor deliverables for controls hardware, including device schedules, topology drawings, and bills of material
Review integrator and OEM designs for compliance with OneMHS architecture and component standards
Drive continuous improvement of specification templates and documentation for scaled deployment
Standards & Code Compliance
Ensure controls hardware designs comply with NEC/NFPA 70, NFPA 79, UL 508A, and applicable IEC standards
Serve as subject matter expert on industrial networking, controls hardware, and low-voltage controls requirements
Conduct design reviews and audits to identify compliance gaps and safety risks
Stay current with EtherCAT Technology Group guidance, industry standards, and regulatory changes
Technical Collaboration & Knowledge Sharing
Mentor junior and mid-level engineers and designers
Lead design reviews for controls architecture and hardware at site and program levels
Collaborate with Controls Software, Operations, Facilities, Construction, WWDE, and Safety teams
Build consensus across stakeholders, suppliers, and integration partners on architecture decisions
A day in the life
Collaborate with Controls Software, integration partners, and suppliers to define and refine the EtherCAT architecture for upcoming fulfillment center projects. Review vendor topology drawings and device schedules, evaluate a new device for inclusion in the approved component list, and work through an integration question with a supplier's engineering team. Validate a new topology or device in the lab before it reaches the field, and support a site team troubleshooting a commissioning issue.
Develop mechanisms that make controls hardware implementations repeatable across multiple simultaneous projects while maintaining the highest standards of safety, reliability, and performance.
