  • Evaluate and compare multiple synthesis routes, manufacturing scales, and multiple asset options.
  • Complete techno-economic evaluations of a variety of processes and chemistries.
  • Have a safety focus during evaluations, highlighting concerns and extra capital that may be required to mitigate potential safety events.
  • Communicate clearly with project teams and management about model results and recommendations both verbally and in writing.
  • Actively participate in multifunctional project teams to guide new product development and decision making throughout the product development cycle.
  • Apply engineering and scientific fundamentals to existing and new areas of interest.
  • Document discoveries in technical reports and potentially contribute to invention disclosures.
  • This role is primarily in the office, however guiding and learning from laboratory efforts is also part of the role expectations.
  • Generate techno-economic tools that are user friendly and enable decision making.
  • Leverage expertise and fundamental knowledge to deliver insights to product teams in the face of uncertainty.
