Field Deployment & Commissioning

• Travel to client sites (50-60%) to support deployment, commissioning, and start-up of PLC-based control systems for data center facilities
• Conduct onsite programming, testing, and troubleshooting of PLC systems controlling HVAC, mechanical, and electrical equipment in mission-critical environments
• Provide remote and onsite technical support during installation, commissioning, and post-deployment phases
• Work directly with clients, contractors, and field teams to resolve integration issues, system errors, and performance concerns
• Implement customer-requested modifications and updates to PLC programs and control strategies in live production environments
• Debug and resolve installation issues during static and dynamic commissioning, including PLC logic, hardware, and communication network troubleshooting
• Support field commissioning teams during system start-up, functional testing, and validation activities to ensure systems meet design specifications
• Diagnose and correct system faults in real-time, often under time-sensitive conditions during critical deployment milestones
• Collaborate with engineering, construction, and vendor teams to ensure successful integration of controls, equipment, and subsystems
• Document field changes, programming updates, system configurations, and lessons learned for project turnover and knowledge transfer
• Provide technical training and support to client operations teams during system handoff
• Participate in design reviews and client meetings to provide field engineering expertise and deployment feasibility input

• 5+ years of experience as a PLC Programmer/Engineer with significant field deployment and commissioning experience
• Experience with Studio 5000 / Rockwell Automation software in field and production environments
• Proven hands-on experience commissioning complex chiller or boiler systems (central plants) in the field
• Experience developing and deploying redundancy strategies and programming redundant PLC controller managers
• Strong troubleshooting and problem-solving skills in high-pressure, time-sensitive field environments
• Ability to work independently onsite with minimal supervision and manage multiple concurrent deployment activities
• Excellent communication and client-facing skills for technical discussions and issue resolution
• Willingness and ability to travel up to 50-60%, including potential for extended site assignments
• Strong organization, task management, and documentation skills in dynamic field conditions
• Valid driver's license and ability to travel domestically (and internationally as needed)

• Bachelor's degree in Software, Mechanical, or Electrical Engineering
• Experience with Ignition SCADA, HMIs, or EPMS/BMS integrations in deployed environments
• Data center or hyperscale infrastructure commissioning experience
• Experience with remote support tools and methodologies
• Familiarity with construction and commissioning processes in large-scale facilities
