Infravision is seeking an Automation & Controls Engineer to design, develop, integrate, test, commission, and support industrial automation and control systems for purpose-built ground systems used in critical infrastructure modernization. Based onsite in Buda, Texas, you will report to the Lead Automation and Controls Engineer and work across controls, electrical systems, industrial networking, software integration, and field commissioning.
This is a hands-on engineering role requiring comfort moving between PLC/HMI development, control-system hardware, industrial networks, software interfaces, and real-world troubleshooting. You will help build reliable, maintainable, secure automation solutions from requirements and architecture through factory testing, deployment, and lifecycle support.
Infravision combines aviation, robotics, and field technology to help modernize the power grid safely, efficiently, and at scale. The technology is deployed in real-world field environments, helping utilities and infrastructure partners improve safety, reduce risk, and accelerate delivery of critical energy infrastructure.
Key responsibilities include:
- Design, program, test, and maintain PLC-based industrial control systems using IEC 61131-3 languages (Ladder Diagram, Structured Text, Function Block Diagram)
- Develop and configure HMI and SCADA applications, including operator displays, alarms, trends, data logging, diagnostics, and integration with PLCs, databases, gateways, and enterprise systems
- Develop or review control-panel layouts, electrical schematics, I/O and loop drawings, network drawings, cable schedules, instrumentation documentation, and bills of materials
- Configure and troubleshoot industrial communications using EtherNet/IP, Modbus TCP/RTU, OPC UA, CAN/CANbus, EtherCAT, MQTT, serial communications, TCP/IP, VLANs, routing, and network segmentation
- Build scripts, utilities, and interfaces using Python, C/C++, C#, SQL, PowerShell/Bash, JSON/XML, REST APIs, messaging systems, and databases to connect controls with external applications
- Integrate PLCs, sensors, RTUs, gateways, and industrial computers with edge and cloud architectures, including telemetry, data processing, remote diagnostics, and local web applications
- Apply practical industrial cybersecurity principles, including segmentation, firewall and access-control configuration, secure remote access, credential/certificate management, and logging
- Develop and execute unit, I/O, integration, FAT/SAT, communications, failure-mode, alarm/interlock, performance, and regression testing; commission systems in the field and perform root-cause troubleshooting
- Create and maintain functional and software design specifications, architectures, I/O lists, PLC/HMI documentation, interface-control documents, test and commissioning procedures, and as-built records
Requirements:
- Bachelor's degree in Electrical Engineering, Controls Engineering, Automation Engineering, Mechatronics, Computer Engineering, or closely related engineering discipline
- Approximately 3+ years of professional experience in industrial automation, controls engineering, systems integration, or related discipline, with demonstrated PLC programming experience
- Hands-on experience with common industrial PLC platforms and HMI/SCADA systems (Rockwell/Allen-Bradley, Siemens, Ignition, FactoryTalk, Wonderware, VTScada, or similar)
- Strong working knowledge of Ethernet and TCP/IP networking and experience with industrial protocols (EtherNet/IP, Modbus, OPC UA, CAN/CANbus, EtherCAT, MQTT, or similar)
- Working knowledge of instrumentation, sensors, actuators, VFDs, motor controls, industrial electrical systems, and ability to interpret electrical schematics, P&IDs, wiring diagrams, and technical specifications
- Working capability with one or more general-purpose programming or scripting languages (Python, C/C++, C#, SQL, PowerShell, or Bash) and familiarity with APIs, databases, Git/version control, and structured software-development practices
- Hands-on experience testing, commissioning, and troubleshooting multidisciplinary systems using engineering and diagnostic tools (DMMs, oscilloscopes, network analyzers, protocol analyzers, packet captures)
- Strong analytical problem-solving, documentation, and communication skills with ability to work effectively across software, electrical, mechanical, technician, operations, vendor, and customer teams
