What is a PLC software engineer?

PLC Software Engineers are professionals who design, develop, and maintain software for programmable logic controllers (PLCs), which are specialized computers used to automate industrial processes. They write and troubleshoot code, configure hardware, and ensure that machinery operates efficiently and safely. PLC Software Engineers often work in manufacturing, energy, automotive, and other sectors where automation is essential. Their skills include programming in languages like Ladder Logic and working with control systems and automation equipment.

What are some typical challenges a PLC software engineer faces when integrating new automation systems into existing manufacturing processes?

PLC Software Engineers often encounter challenges such as ensuring compatibility between new automation systems and legacy equipment, minimizing production downtime during system upgrades, and troubleshooting unforeseen communication issues between devices. Collaboration with cross-functional teams—including electrical engineers, maintenance staff, and production operators—is essential to address these challenges effectively. Strong documentation and version control practices also help manage complex system changes and ensure smooth transitions during integration projects.

What are the key skills and qualifications needed to thrive as a PLC software engineer, and why are they important?

To thrive as a PLC Software Engineer, you need a strong background in automation, electrical engineering, and programming, typically backed by a degree in engineering or a related field. Familiarity with PLC programming languages (such as ladder logic), SCADA systems, HMI development, and certifications from automation providers like Siemens or Rockwell Automation are crucial. Strong problem-solving abilities, attention to detail, and effective communication set top candidates apart. These skills ensure reliable system performance, efficient troubleshooting, and seamless integration in industrial automation environments.

What is the difference between Plc Software Engineer vs Automation Engineer?

AspectPlc Software EngineerAutomation Engineer
CredentialsTypically requires a degree in electrical, computer, or automation engineering; certifications in PLC programming are commonSimilar credentials; often holds degrees in engineering or automation, with certifications in control systems
Work EnvironmentDesigns and programs PLC systems in manufacturing, industrial, or process control settingsWorks on overall automation systems, including PLCs, robotics, and control hardware in industrial environments
Industry UsagePrimarily in manufacturing, process control, and industrial automationUsed across manufacturing, robotics, and complex automation projects

While both roles involve automation and control systems, a Plc Software Engineer specializes in programming and developing PLC software, whereas an Automation Engineer has a broader scope, including designing entire automation systems and integrating various control technologies.

Is PLC software engineering a good career?

PLC software engineering is a stable and in-demand field within industrial automation, involving programming and maintaining programmable logic controllers used in manufacturing and process control. It often requires knowledge of ladder logic, control systems, and related tools, with opportunities for certification and career advancement. The role offers steady employment prospects and the potential for specialization in various industries.

Is PLC still in demand?

PLC Software Engineers are still in demand due to the ongoing need for automation in manufacturing, energy, and industrial sectors. Skills in ladder logic, programming, and familiarity with PLC hardware like Siemens or Allen-Bradley are valuable for these roles.

Job description

About the Role
Are you an engineer who enjoys a challenge? Are you excited about working for an FFRDC focused on areas critical to national security? Do you want to join a collaborative team that develops and uses best-in-class tools to enable end-to-end software development?
We are seeking a PLC Software Development Engineer to join our engineering team. The ideal candidate will have strong hands-on experience developing software for U.S. vendor-based PLC platforms using Structured Text (ST) programming language. This role will play a key part in designing, programming, testing, and maintaining industrial control systems that support mission-critical operations.
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.
