About the Team
The Data & AI team is responsible for building B Lab's data platform, delivering on business priorities, and scaling AI adoption across the organization. The team reports directly to the CTDO. The Data & ML Platforms team owns the data platform, ML infrastructure, and the foundational data models the rest of the Data & AI team depends on - the supply-side capability layer that Business & Data Priorities and AI Enablement build on.
About the Opportunity
As a Junior Data Engineer within the Data & ML Platforms pillar, you build and maintain the data pipelines and infrastructure the rest of the Data & AI team depends on.
Your first priority is unblocking the onboarding of new data sources - currently one of the team's top hiring priorities, paused pending this hire. You will absorb data engineering work currently split between the Senior Machine Learning Engineer and the Pillar Lead, freeing them to focus on ML infrastructure and platform strategy respectively.
You will work closely with the Senior Analytics Engineer on core data modeling and with the Data Governance Lead on data standards, definitions, and compliance.

Platform Support & Cross-Team Collaboration (35%):

• Support Foundational Data Models: Work with the Senior Analytics Engineer to maintain the core data models the rest of the team depends on.
• Ensure Data Availability for Consumers: Make sure the data needed by Data Analysts and the Senior Machine Learning Engineer is reliably available.
• Follow Data Governance Standards: Apply the data standards, definitions, and sensitivity classifications set by the Data Governance Lead.

Strategic Innovation & Business Impact (10%):

About B LabB Lab™ is the nonprofit behind Certified B Corporations™, a community of businesses that meet verified social, environmental, and governance standards. Together, our movement is working towards a more inclusive, equitable, and fair economic system.
Our historyB Lab began in 2006 with the idea that a different kind of economy was not only possible - it was necessary. Our founders Andrew Kassoy, Bart Houlahan, and Jay Coen Gilbert believed there was a better way to do business: better for workers, better for communities, and better for the planet. When our movement's first 81 Founding B Corps signed the Declaration of Interdependence in 2007, they were not just proposing a better way of doing business. They were proposing a different definition altogether.
What we've achievedB Lab became known for certifying B Corporations™, companies that meet verified standards of social and environmental performance, accountability, and transparency. But we do much more than that. We help mobilize a global community of businesses committed to collective action on society's most critical challenges. In 2010, B Lab was part of successfully drafting and passing benefit corporation in Maryland, the first U.S. state to do so. This created a legal framework that allows companies to keep their values of care and community, not just shareholder value, at the forefront. Today, benefit corporation legislation is active in 52 jurisdictions around the world.
Our futureIn 2024, leaders from across the network agreed to evolve into a more integrated organization that embodies interdependence. This next iteration of our global network will balance global coherence with local agency to achieve our vision of economic systems change. We are now building this future together.
