Apply and review process models using tools such as GPS-X, BioWin, SUMO, and Visual Hydraulics to assess alternatives, troubleshoot complex issues, and optimize treatment performance.
Review process flow diagrams, P&IDs, calculations, specifications, equipment selections, and technical reports to uphold quality and consistency across project deliverables.
Lead technical workshops and clearly communicate recommendations to clients, operators, vendors, and multidisciplinary design teams.
Guide permitting, contract administration, commissioning, and construction-support activities throughout the project lifecycle.
Strengthen our technical community by providing QA/QC, mentoring junior and intermediate engineers, leading proposals, and supporting trusted client relationships.

Strong knowledge of process controls, instrumentation, plant operations, commissioning, permitting, contract administration, and construction-support services.
Proven ability to independently lead technical work, complex proposals, and multidisciplinary project teams in a consulting environment.
Strong technical writing, presentation, client communication, proposal-development, and problem-solving skills.
A valid driver’s licence and willingness to travel periodically to client sites and project locations.
