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. 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.

About The Role

As CREW’s Data Engineer, you will lead the architecture, development, and scaling of CREW’s data platform in collaboration with the Science, Product, and Operations teams.

You will play a key role in designing and implementing robust, enterprise-scale data infrastructure that serves as the backbone for carbon removal verification (MRV), operations optimization, and scientific analysis across multiple deployment sites. You will be responsible for building scalable, reliable data pipelines to ingest, process, and standardize diverse data streams from instruments, partner utilities, and SCADA systems, while establishing and enforcing data governance and quality standards that ensure accuracy, reliability, accessibility, and compliance with carbon crediting requirements.

Your work will accelerate CREW’s data velocity and reliability, cementing our position as a leader in the carbon removal industry as we expand in scale and impact. This is an ideal opportunity for a detail-oriented, mission-driven engineer with experience building production-grade data infrastructure for complex, multi-site operations in climate, environmental, or utility contexts.

This position is a full-time role. Location will be remote, working East Coast hours, with optional hybrid work out of our offices in Brooklyn, NY or New Haven, CT.

Responsibilities

• Design, implement, and maintain CREW’s enterprise-scale data platform, ensuring scalability, reliability, and reproducibility across multiple teams and projects.
• Own data governance, naming standards, and metadata standards across CREW’s data infrastructure.
• Build and maintain processing workflows for existing and new measurement streams, improving automated QA/QC processes to check, validate and audit data.
• Stand up a secure, accessible cloud database with reliable ingestion, transformation, and retrieval paths; implement data security, backup, and cost controls.
• Integrate external, industrial-grade cloud systems with CREW’s data infrastructure.
• Package data pipelines and tools as maintainable, production-ready projects with CLI entry points, CI/CD, unit tests, clear documentation and SOPs.
• Partner with Science, Engineering and Operations teams to deliver decision-ready datasets and dashboards for MRV, operations, and analytics.
• Mentor and support teammate contributions to company codebases by leading code reviews, establishing engineering standards, and promoting best practices in software and data engineering

Experience Requirements

• 5-8+ years of hands-on experience in data engineering, software engineering, or equivalent technical roles with production ownership; strong track record leading the design and implementation of enterprise-scale data platforms (utilities/IoT/climate-tech preferred).
• Fluent in Python and SQL; comfortable with schema design, time-series data, and scientific instrument files.
• Built and operated data pipelines/orchestrated workflows on cloud resources (AWS, GCP).
• Pragmatic about data infrastructure and deployment strategies; rigorous about testing, security, documentation, and clear communication.
• Comfortable designing lightweight front-end or dashboard functionality to deliver insights to end-users.
• Experience mentoring and supporting other engineers, guiding code quality, maintainability, and standards.
• Ability to thrive in a fast-paced, startup environment; practices extreme ownership, high empathy, and a growth mindset.

Bonus Qualifications

• Experience integrating SCADA, IoT, or third-party utility systems.
• Experience developing front-end dashboards and visualization platforms.
• Familiarity with MRV, carbon accounting standards, and environmental QA/QC frameworks.
• Experience with scientific software or lab data management exposure, including containerizing models and workflows.
• Familiarity with MLOps and specific frameworks (PyTorch, Apache Spark, TensorFlow).
• Prior experience in climate tech, environmental services, or utility sectors.

Compensation

The annual salary range for this position is competitive and will depend on many factors including experience, education, and expertise. We offer a competitive benefits package with insurance, vacation, retirement, and equity options.
