Job Description
Industrial Controls & SCADA Engineer Location:
Denver, CO (On-site required initially; hybrid eligible after 6 months) About WSI WSI is a designer and manufacturer of wastewater treatment and water recycling systems serving municipal, industrial, food & beverage, and oil & gas markets. We specialize in integrated treatment systems including DAF pretreatment and biological processes, delivering fully engineered, factory-tested solutions. Our projects span across North America and internationally, with a strong presence in locations such as Hawaii and Western Canada. Position Overview We are seeking a mid-level Industrial Controls & SCADA Engineer to lead the development of PLC, HMI, and plant-wide SCADA systems for packaged and site-built water and wastewater treatment facilities. This role offers end-to-end ownership of control systems—from PLC programming and HMI development through SCADA architecture, factory testing, commissioning, and cloud-based data systems. You will work from established control narratives and tagging structures while collaborating with process and design engineers to deliver complete, high-performance control systems. Key ResponsibilitiesPLC & HMI
Development- Develop PLC programs using Studio 5000 Logix Designer on Allen-Bradley CompactLogix systems
- Design and implement HMI applications using: o FactoryTalk View Studio/ PanelView Plus o Optix o iX Developer/Beijer HMIs
- Implement communication protocols including Ethernet/IP and Modbus TCP
- Execute control strategies based on process narratives and system requirements SCADA System Development
- Design and implement full plant-wide SCADA systems including: o Operator workstations and HMI network architecture o Data collection and historian systems (SQL-based) o Alarm management, trending, and reporting systems
- Develop high-performance
HMI/SCADA
interfaces aligned with modern usability standards- Configure and integrate systems using OPC UA and standard industrial protocols
- Implement secure remote access via VPN and web-based clients
- Support cybersecurity best practices, user access control, and system reliability Cloud Data & Dashboard Systems
- Develop and maintain cloud-based data pipelines and dashboards using: o Node-RED o InfluxDB o Grafana
- Configure MQTT-based data transmission from field systems
- Support infrastructure including Linux systems, Docker containers, VPNs (CloudConnexa / OpenVPN), and NGINX Testing, Commissioning & Startup
- Lead Factory Acceptance Testing (FAT) at WSI's Denver facility
- Develop and execute test procedures for PLC, HMI, SCADA, and network systems
- Travel for system checkout, commissioning, and process startup
- Perform field troubleshooting of controls, SCADA, and communication systems Collaboration & Continuous Improvement
- Work closely with process engineers, design engineers, and project managers
- Provide input on control strategies to improve system performance and operability
- Support legacy systems (including limited Mitsubishi GXWorks platforms) Travel Expectations
- Travel varies based on project phase
- Periods of minimal travel interspersed with commissioning trips (~2 weeks typical)
- Projects may include travel to locations such as Hawaii and Canada QualificationsRequired
- Experience programming Allen-Bradley PLCs (CompactLogix)
- Experience developing HMI systems
- Ability to independently execute controls systems from design through commissioning Preferred
- Experience developing SCADA systems (architecture, historian, alarms, reporting)
- Experience with cloud/data systems (MQTT, Node-RED, InfluxDB, Grafana)
- Electrical Engineering degree or similar technical background
- Experience with industrial water/wastewater or similar process systems
- Familiarity with networking, VPNs, and Linux-based systems Work Environment

- Sick time (6 days/year) What Success Looks Like
- Independently deliver two complete
PLC/SCADA
systems within the first year- Successfully support commissioning and startup of assigned projects
- Develop reliable, maintainable SCADA and cloud-based monitoring systems
- Contribute to improved system performance, usability, and data visibility Why This Role Stands Out
- Full lifecycle ownership: design → build → test → startup → data systems → support
- Exposure to both industrial controls and modern SCADA/cloud architecture
- Hands-on commissioning experience in unique project locations
- Collaborative, multidisciplinary engineering environment Let's Build Something Together!
