About the role

Key responsibilities & impact

Serve as the senior-most technical authority for PLC engineering standards, architecture, programming practices, and complex technical decisions.
Set and maintain PLC programming standards, code review expectations, documentation requirements, reusable code libraries, templates, naming conventions, and best practices.
Lead architectural decisions for new, complex, high-risk, or highly visible projects.
Define scalable PLC control strategies, redundancy approaches, I/O structures, network design principles, alarm strategies, and system recovery methods.
Serve as the final technical escalation point for complex PLC programming, troubleshooting, commissioning, integration, and field issues.
Stay current on major PLC platforms, automation technologies, control system trends, and relevant innovations that can improve Divcon’s engineering capabilities.
Own the technical quality bar for PLC engineering deliverables across the team.
Establish and improve code review processes, design review practices, technical validation methods, and project turnover standards.
Conduct or oversee technical reviews at key project milestones.
Ensure PLC solutions are reliable, maintainable, scalable, supportable, and aligned with Divcon standards and customer requirements.
Drive continuous improvement in how the PLC Engineering team programs, tests, documents, commissions, and delivers PLC solutions.
Partner with SCADA, SCA, field, commissioning, project management, and other engineering counterparts to ensure technical consistency at integration points.
Take ownership of the most technically demanding, complex, ambiguous, or highest-risk PLC engineering challenges.
Provide technical complexity assessments during project scoping, estimating, and planning.
Support project teams in defining control strategies for large-scale data center, central plant, HVAC, mechanical, electrical, and critical infrastructure systems.
Guide resolution of severe or time-sensitive technical issues during start-up, commissioning, customer acceptance, and post-deployment support.
Advise Lead PLC Engineers on technical approach, architecture, project risk, and issue resolution.
Provide advanced technical mentorship to Lead PLC Engineers, Senior PLC Engineers, PLC Engineers, and Associate PLC Engineers.
Act as a dotted-line technical coach for the PLC Engineering team while remaining outside the people-management chain.
Partner with the PLC Engineering Manager to identify skill gaps, define development priorities, and build structured technical development plans.
Lead or organize internal technical training sessions, code walkthroughs, architecture reviews, lessons-learned sessions, and best-practice discussions.
Create an environment where engineers feel comfortable bringing forward difficult technical problems, design questions, and escalation needs.
Support onboarding and technical ramp-up for new PLC Engineering team members.
Represent Divcon’s highest level of PLC technical expertise in client-facing meetings, design reviews, technical escalations, and strategic discussions.
Partner with project managers, engineering managers, SCADA engineers, SCA engineers, field technicians, commissioning teams, vendors, contractors, and system integrators to ensure seamless delivery.
Translate complex technical issues into clear recommendations for both technical and non-technical stakeholders.
Influence technical decisions without relying on formal management authority.
Help build Divcon’s reputation for technical excellence in PLC engineering, critical infrastructure controls, and data center automation.
