How to Apply for Principal Wastewater Process Engineer

at CREW

🏢 About CREW

CREW is unique for combining wastewater treatment with carbon sequestration, using advanced chemistry, natural minerals, and AI to create process intensification technology. They're tackling two critical environmental challenges simultaneously—making wastewater treatment more efficient while permanently removing CO₂ from the atmosphere. This dual mission makes CREW particularly appealing for engineers passionate about climate tech and sustainable infrastructure.

About This Role

As Principal Wastewater Process Engineer, you'll lead the technical strategy and implementation of CREW's integrated solution, bridging biological nutrient removal, chemical dosing, and downstream processes. You'll analyze operational data from deployments to drive improvements and validate process performance through rigorous experimentation. This role is impactful because you'll directly influence how wastewater treatment facilities operate while advancing carbon sequestration technology.

💡 A Day in the Life

A typical day might involve analyzing operational data from CREW's deployments to identify performance trends, then designing experimental protocols to validate process improvements. You could spend part of the day collaborating with the commercial team to prepare for client engagements, using your wastewater expertise to influence decision-makers. The role balances technical strategy, data analysis, and client-facing responsibilities to advance both wastewater efficiency and carbon sequestration.
