## About the Role

* Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, Software Engineering, or a related field; a two-year technical program in a related field, combined with relevant hands-on experience, is an acceptable alternative
 * 3+ years of software development experience, including industrial controls programming, or strong software engineering experience with demonstrated aptitude to learn PLC platforms
 * Strong programming fundamentals: modular/structured design, state machines, Boolean logic, data structures, and software testing and validation
 * Hands-on experience programming industrial PLCs on Rockwell (Studio 5000) and/or Beckhoff (TwinCAT), or equivalent software experience with a clear path to ramp on these platforms
 * HMI development experience (Beckhoff, Ignition, or comparable)
 * Experience using version control (Git) in a collaborative, multi-developer environment
 * Strong debugging and troubleshooting skills, and a documentation-minded approach to code
 * CI/CD or DevOps practice and automated/structured testing
 * Industrial Automation standard language experience (IEC 61131-1) / structured-text and ladder logic programming
 * Vision systems, servo/motion control, and robotics integration

## Description

* Execute the software design, development, and debug of multi-station automated assembly and test systems
 * Design, structure, and develop PLC application code on Rockwell (Studio 5000), Beckhoff (TwinCAT) or similar - clean, modular, reusable, and well-documented
 * Architect machine software: state machines, sequencing, fault handling, and standard/reusable code frameworks
 * Develop machine HMI applications (Beckhoff or Ignition) for operator interaction, data collection, and traceability
 * Program and integrate peripheral devices (servo/motion drives, robotics, vision and inspection systems, smart sensors, and other field hardware)
 * Design and program equipment to customer and internal build specifications, applying established design standards and techniques
 * Develop software design specifications from requirements
 * Apply software engineering best practices across controls deliverables: version control (Git - GitHub / Azure DevOps), branching/merging, code review, and configuration management
 * Build structured software testing and validation
 * Develop machine-level data, traceability, and integration features for production and audit readiness
 * Translate electrical and I/O designs into robust, maintainable control software, and assist with that design work as project needs require
 * Support customer start-ups and site acceptance testing as necessary
 * Partner with mechanical, project management, and quality teams across the project lifecycle
 * Serve as a software point of contact for customers on controls-related aspects of projects Any other duties as assigned.
