• Software and Hardware Integration: Assist in integrating software applications with hardware infrastructure, including setting up servers, virtual environments, and configuring networking equipment (Ethernet switches, routers, firewalls).
• Design and Documentation: Interpret design documents and control strategies to develop functional code and logic. Document programming workflows, software configurations, and testing procedures for project records.
• Construction Support and Commissioning: Participate in Engineering Services During Construction (ESDC) tasks including field testing, submittal review, troubleshooting, and site-based programming adjustments, with reduced assistance from group leads.
• Mentorship and Collaboration: Begin to mentor Staff Programmers and provide technical support within the project team. Coordinate with process, electrical, and instrumentation engineers to align programming with overall system design.
• Process Improvement: Contribute to the development and refinement of programming standards, object libraries, and internal tools aimed at improving team efficiency and software consistency.

• Programming Fundamentals: Working knowledge of Microsoft Office and basic familiarity with at least one programming language (e.g., Python, C#, VB.NET).
• Control Systems Exposure: Basic understanding of control system components (PLCs, HMIs, RTUs, PACs) and industrial automation concepts.
• Technical Aptitude: Ability to read wiring diagrams and P&IDs. Comfortable learning new software and technical systems quickly with support.
• Infrastructure Awareness: Introductory knowledge of networking equipment and system architecture relevant to SCADA (servers, switches, virtualization platforms).
• Team-Oriented Mindset: Strong communication skills and ability to take direction. Willingness to collaborate and contribute within a multidisciplinary project team.
• Reliability and Follow-Through: Demonstrates good time management, attention to detail, and ability to track and complete assigned tasks with accountability.

• Education: Associate degree in Computer Science, Electrical/Controls Technology, Mechatronics, or a related technical field. Relevant certifications such as Control Systems Technician (CST), Siemens Mechatronic Systems Certification Program, or PLC training are a plus.
• Project Experience: Internship or hands-on experience with industrial control systems, including exposure to SCADA/HMI software, PLC logic, or plant automation projects.
• Platform Familiarity: Exposure to software platforms such as Rockwell Studio 5000, FactoryTalk View, AVEVA System Platform, or Ignition is a plus. Basic awareness of protocols such as Modbus, OPC, or Ethernet/IP is desirable.
• Additional Strengths: Initiative in learning new technologies, problem-solving capabilities, and a growth mindset toward developing deeper expertise in automation and controls.
