Principal Wastewater Process Engineer

Are you ready to join Connecticut Innovation’s vibrant community of innovators? Connecticut Innovations (“CI”) is Connecticut’s strategic venture capital arm, and we are passionate about serving our portfolio of 220+ companies across various industries, with strengths in life sciences, technology, and climate tech.

Come join one of our quickly growing portfolio companies, Home | CREW Carbon!

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. Today, we help wastewater treatment facilities and operators:

• Stabilize pH & alkalinity 24/7
• Eliminate hazardous chemicals & cut costs
• Avoid $100M+ infrastructure upgrades
• Capture & Store CO2

We are currently deploying this technology across the US and Europe. In addition, we’ve signed $30M+ in carbon removal offtake agreements with leading corporations looking to meet their climate goals, supercharging geographical CREW’s expansion.

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

We are funded by Counteract, ReGen, Ponderosa, Connecticut Innovations and others. We've secured large contracts with the premier buyers of carbon credits through the Frontier Climate Fund (Stripe, Shopify, Autodesk, McKinsey, among others) and have been selected by the Department of Energy as one of the few potential suppliers of high-quality carbon credits to the federal government.

AAs Principal Wastewater Process Engineer, you will serve as the primary technical authority on the integration of CREW’s process optimization & decarbonization solution within biological treatment at utilities across the country and world. You will go beyond the typical engineering design process to drive CREW’s technical strategy. This is a leadership-critical role designed for a senior expert who can interpret complex data to drive internal R&D and 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 municipal wastewater resource recovery facilities (WRRFs).

Through deep analysis of deployment data, you will generate the clear, credible interpretations needed to demonstrate our technology’s operational and economic value to utilities and other stakeholders via improved biological treatment, process intensification, and greenhouse gas removal. You will oversee experimental and analytical design for lab and field teams, ensuring that every experiment and data stream directly supports technical validation, operational readiness, and scale-up of CREW’s process optimization and decarbonization solutions.

This position is a full-time role. Location will be onsite at our office in Brooklyn, NY or New Haven, CT.

• Lead Technical Strategy: Lead the technical strategy and implementation of CREW’s solution at the intersection of biological nutrient removal (BNR), chemical dosing, and downstream processes.
• Expert Data Interpretation: Analyze operational data from CREW’s deployments, identify metrics to track performance, and drive actionable decisions toward operational improvements or new solutions.
• Experimental Oversight: Direct the Tech and Operations teams on experimental protocols and data collection requirements to rigorously validate process performance.
• Stakeholder Engagement: Serve as the subject matter expert in client engagements to support Commercial Team by providing the scientific rigor and operational confidence required to influence decision makers, engineering staff, plant supervisors, and operators.
• Process Modeling & Design: Support the development…
