🏢 About CREW

CREW is a unique company that combines wastewater treatment with carbon sequestration, using advanced chemistry, natural minerals, and AI to create more efficient and environmentally impactful solutions. They focus on process intensification technology with decarbonization at its core, making them an attractive employer for engineers passionate about sustainability and innovation in environmental engineering.

About This Role

As a Senior Engineer - Wastewater, you'll be responsible for developing process flow diagrams, mass/energy balances, and dosing system designs while serving as technical lead during partner engagements. This role directly translates lab results and field data into actionable insights, making it impactful by driving both operational efficiency and CREW's decarbonization mission through technical documentation and cross-team coordination.

💡 A Day in the Life

A typical day might involve developing process flow diagrams for new wastewater treatment systems, analyzing field data from ongoing projects to optimize dosing systems, and coordinating with Technology and Operations teams to translate findings into actionable insights. You'd also spend time creating technical documentation and preparing for partner engagements where you'll serve as technical lead on wastewater process and process-mechanical support.

🎯 Who CREW Is Looking For

  • Has 5+ years of experience in wastewater process engineering with demonstrated expertise in process flow diagrams and mass/energy balances
  • Possesses strong technical documentation skills and experience translating lab/field data into engineering designs and recommendations
  • Has experience serving as technical lead in client or partner engagements, particularly in process-mechanical support roles
  • Shows understanding of decarbonization technologies or sustainable wastewater treatment methods, aligning with CREW's mission
