ABOUT A6 LABS

A6 Labs is a technology company building national carbon registries for governments aligned with Article 6 of the Paris Agreement. Our mission is to deliver transparent, efficient, and scalable systems that enable countries to manage and trade carbon credits in line with international climate goals.

You’ll collaborate closely with our frontend and product teams to deliver features end-to-end and ensure smooth integration across the platform.

REQUIREMENTS
