Responsibilities

Monitor the work of assigned staff on technical matters pertinent to project assignments; maintain assigned tasks within schedule and budget to fit the needs of the projects
Prepare and review complex calculations
Prepare and review mechanical systems/equipment designs
Prepare documented design input for drawing production (i.e., P&IDs, machine layouts, general arrangements, etc.)
Prepare and review equipment specifications
Communicate with vendors via clearly written and complete specifications
Prepare and review reports/studies
Develop single-discipline/simple-scope project budgets, schedules, and project work plans; monitor own work to ensure it is completed within budget and on schedule
Interface directly with customers in project meetings
Mentor junior engineers
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.
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.
Oversee engineers who program or script (e.g., Python, MATLAB, advanced Excel) to automate engineering tasks, with review of automated outputs.
