Key Responsibilities
- Design, implement, and maintain PLC programs, with a primary focus on Structured Text (ST).
- Collaborate with cross-functional engineering teams to define control system requirements and ensure software solutions to meet project objectives.
- Conduct thorough testing, debugging, and validation to ensure reliable and safe operation of automation systems.
- Troubleshoot and optimize existing PLC programs to improve system performance and maintainability through technical analysis and objective data.
- Develop technical documentation including system specifications, test procedures, and user guides.
- Provide on-site and remote support for system commissioning and upgrades.
Who you are:
- You have a BS in Computer Science, Electrical Engineering, or a related discipline with 10 years of experience; OR an MS in the same fields with 8 years of experience; OR a PhD with 5 years of experience.
- You have hands-on experience with Rockwell Automation PLCs.
- You are proficient in IEC 61131-3 Structured Text programming language.
- You have a strong understanding of industrial control systems, automation architectures, and communication protocols such as Ethernet/IP and Modbus.
- You are experienced with configuration management tools (e.g., Git, SVN), collaboration software platforms (e.g., GitLab, Jira), along with associated best practices.
- You have worked in a collaborative team environment as a software developer, software engineer, verification engineer, or a similar role.
- You understand the Department of War (DoW) Systems Engineering lifecycle and the Software Development Lifecycle (SDLC) from requirements management to sustainment.
- You have strong communication skills and the ability to convey difficult engineering or technical challenges to stakeholders.
- You are willing to work 100% of your week onsite at either the SEI or customer facility autonomously with minimal supervision.
- You have a willingness to travel (25%) outside of your office location to other SEI offices, sponsor sites, conferences, and offsite meetings.
- You can pass a background check and obtain and maintain an active Department of War (DoW) security clearance.
Preferred Qualifications
- Experience with C and C++ programming languages, particularly in embedded or industrial software environments.
- Familiarity with additional IEC 61131-3 languages (Ladder Diagram, Function Block Diagram, Sequential Function Chart).
- Experience with Windows OS and common tech stacks for development.
- Proficiency in HMI and SCADA development and integration.
- Knowledge of virtualization technologies (e.g., VMware, Hyper-V, Docker) for testing environments.
- Experience with static code analysis tools and checking compliance with industry standards.
- Understanding of safety instrumented systems and standards (IEC 61508, ISO 13849, etc.).
- Knowledge of multiple PLC platforms and industrial control systems.
- Strong problem-solving skills, with the ability to work independently and in team settings.
