SCADA Engineer III - Critical Infrastructure

Smart Tech Contracting delivers turnkey BAS & EPMS solutions for mission-critical colocation and hyperscale data centers operating at national program scale. As a Master Systems Integrator (MSI), we unify controls construction (DDC, PLC, SCADA) with software engineering, optimized graphics / UI standards, and program-level governance.

Complex integrations are delivered cleanly, consistently, and fast. Our teams thrive in high-stakes environments where quality control and uptime matters, schedules are compressed, and coordination is everything.

Join us and be part of a team where your voice matters, your work makes an impact, and your growth is a shared priority.

SCADA Engineer III – Critical Infrastructure

Remote – United States; limited project-based travel required (On-site presence primarily for design reviews, FAT, IST, commissioning strategy, or critical technical escalations) OR Atlanta, GA OR Dallas, TX

The Senior SCADA Engineer – Level III is a high-level individual contributor responsible for designing, developing, and supporting SCADA systems across mission-critical infrastructure projects. This role focuses on system design, development, integration, and execution
, operating under established standards and architecture while contributing technical expertise across multiple projects. Senior SCADA Engineers are expected to work independently on complex scopes while escalating higher-risk architectural decisions as needed.

While predominantly remote, this role includes on-site engagement during critical milestones such as factory acceptance testing (FAT), integrated systems testing (IST), commissioning, and high-risk troubleshooting events.

• Design and develop SCADA systems in accordance with project requirements and STC standards
• Translate design intent, sequences of operation, and operational requirements into maintainable SCADA configurations, scripts, and logic
• Develop SCADA code, templates, and reusable components as assigned
• Configure alarms, graphics, and data models consistent with established architecture
• Review and refine SCADA implementations for performance, reliability, and consistency

• Coordinate SCADA engineering efforts with Project Managers, Engineers, Field Leadership, and commissioning teams
• Participate in design reviews, coordination meetings, and commissioning planning
• Support integration with third-party systems, packaged equipment, and external vendors
• Identify technical risks within assigned scope and propose mitigation strategies

• Support FAT, IST, and commissioning activities as required
• Perform peer reviews of SCADA configurations and development work within assigned scope
• Assist with troubleshooting during commissioning and live system cutovers
• Ensure implementations align with standards, safety requirements, and design intent

• Provide guidance and technical support to junior engineers as assigned
• Contribute to internal documentation, standards, and best practices
• Participate in knowledge sharing and continuous improvement initiatives

Performs Other Related Duties as Assigned

• 4–6 years of experience engineering or developing SCADA systems in mission-critical, industrial, utility, or infrastructure environments
• Demonstrated experience designing and developing SCADA systems (not solely configuring HMIs)
• Strong understanding of:
  • SCADA architecture and data modeling
  • Alarm management and HMI/graphics philosophy
  • System integration and communications
  • Commissioning…
