Head of Wastewater Process & Technology

CREW Carbon Overview

CREW’s technology and services make wastewater treatment cheaper and more efficient, while permanently sequestering CO2. Leveraging advanced chemistry, natural minerals, and AI, we’ve developed and are deploying a category-defining process intensification technology, with decarbonization at its core.

We help wastewater treatment facilities and operators:

• Improve the efficiency of existing, legacy infrastructure
• Eliminate hazardous chemicals & reduce operational costs
• Avoid $100M+ infrastructure upgrades
• Capture & Store CO2

Today, we are currently deploying this technology across the US. In addition, we’ve signed $33M+ in carbon removal offtake agreements with leading corporations — including JP Morgan, Google, and Stripe — looking to meet their climate goals, supercharging CREW’s expansion.

CREW has offices and labs in New Haven, CT and Brooklyn, NY.

Position Overview

As Head of Wastewater Process & Technology at CREW Carbon, you will serve as the primary technical authority on the integration of CREW’s wastewater process optimization & decarbonization solution at utilities across the country and world.

This is a leadership-critical role designed for a senior expert who can interpret complex data to drive internal R&D and external operations, while influencing external utility leadership.

You will play a pivotal role in accelerating the application of CREW’s technology by translating data from laboratory studies and full-scale deployments into rigorous, defensible technical insight.

You will quantify and articulate the value CREW delivers through process intensification within biological treatment systems, and you will drive the internal data collection, analysis, and modeling required to support those conclusions and enable scale across treatment facilities.

This role will work closely with CREW Carbon’s world-class Advisory team and CEO to define scientific priorities, mentor science team members, and drive CREW’s mission through innovative research and rigorous analysis.

Experience Requirements

• Bachelor’s degree (required) in Environmental Engineering, Chemical Engineering, Civil Engineering, or a related field; a Master’s or PhD degree is a bonus.
• 10+ years of experience in wastewater process engineering, biological treatment design, or related fields.
• Strong understanding of wastewater treatment processes, including nutrient removal, solids handling, and pH and alkalinity control.
• Experience developing and reviewing PFDs, P&IDs, site layouts, mass balance calculations, and process unit design.
• Exceptional technical writing skills, with the ability to translate complex process science into clear, defensible documents for utility executives, consulting engineers, and other stakeholders.
• Familiarity with process modeling tools (BioWin, SUMO, GPS-X, ASM libraries, or equivalent).
• Familiarity with analytical methods used in wastewater and aqueous chemistry system characterization (e.g., IC, TIC, ICP) and ability to interpret analytical data.
• Experience with statistical programming and modeling (e.g., Python, R, MatLab).
• Comfortable working in a rapidly evolving work setting and able to quickly synthesize new information to proactively adjust focus and maintain high-impact results.
• Ability to travel periodically to project sites.
• You practice extreme ownership (no task is too small).
• You love being in the trenches with your team and working with high empathy.
• You have a growth mindset.

Bonus Qualifications

• Experience with capital improvements, facility expansions, or process upgrades at municipal WRRFs.
• Experience in carbon capture, carbonate chemistry, or water-chemistry-based carbon removal technologies.
• Field experience with pilot systems, process commissioning, or operational troubleshooting is highly desirable.
• Experience integrating instrumentation, controls, and monitoring systems for process optimization.
• Experience with CAD software, including AutoCAD, Civil 3D, or Revit.
