  • Support capital, reliability, and debottlenecking projects by contributing to process design elements such as PFDs, P&IDs, mass and energy balances, and equipment specifications
  • Provide technical guidance to operations and maintenance teams, including training on SMR and ammonia process fundamentals.
  • Support the development and application of best practices for ammonia handling, storage, and distribution across assigned facilities.
  • Collaborate with senior engineers and site leadership to drive continuous improvement.
Typical Education
  • Bachelor's degree in Chemical Engineering or a related technical discipline.
Relevant Experience
  • 5-8 years of experience in ammonia production, syngas generation, or closely related chemical processes.
  • Direct experience with steam methane reforming is required, including reformer operation, catalyst performance, and heatbalance fundamentals.
  • Familiarity with OSHA 1910.119 and Process Safety Management principles.
  • Experience with process modeling tools (e.g., Aspen HYSYS) preferred but not required.
  • Strong analytical and problemsolving skills with the ability to work crossfunctionally in operations environments.
