Responsibilities will include, but are not limited to:

  • Reviewing Critical Digital Asset (CDA) determinations and assessments for technical accuracy.
  • Addressing related plant corrective actions and notifications. 
  • Confirming the configuration of devices installed at the site based on network diagrams and system documentation. 
  • Supporting installation of software and hardware on plant digital systems.
  • Performing tasks for changing device settings to implement cyber security controls. 
  • Performing technical supports requested by the Digital Engineering and Cyber Security supervisors.
  • Performing other tasks as related to Cyber Security.

  • You are expected to lead others in taking engineering problems from issue to solution by setting expectations for using data and modern tools such as automation and AI to improve workflows, reduce rework, and deliver cost-effective designs.
  • Leaders in these roles often direct automation and process-improvement work, for example, how teams automate calculations, summarize technical documents, or generate design documentation and guiding when and how AI or agentic AI tools are used while ensuring results are checked.
  • Overseeing engineers who program or script (e.g., Python, MATLAB, advanced Excel) to automate engineering tasks, with review of automated outputs, is valued but not required.
  • We also value additional learning, such as a minor, certificate, or other experience in Computer Science, Artificial Intelligence, Software Engineering, or related fields that enables effective oversight of automation and agentic AI-enabled engineering workflows.
