at Credential Engine

🏢 About Credential Engine

Credential Engine is a non-profit organization dedicated to mapping the credential landscape to help individuals find the best pathways for learning and careers. They offer a unique opportunity to work on national-scale data infrastructure that directly impacts education and employment outcomes. Their mission-driven culture and focus on open data standards make them a standout employer for those seeking meaningful work.

About This Role

This role involves designing and scaling software systems that integrate AI into production environments, specifically for extracting and transforming web-based credential data using CTDL xTRA. You'll also build an AI layer for insights and skills-to-jobs matching, leveraging large and small language models. Your work will directly power tools that help millions of people navigate their educational and career paths.

💡 A Day in the Life

A typical day might start with a stand-up meeting with your remote team to discuss progress on integrating an LLM into the data extraction pipeline. You'll then dive into coding, perhaps optimizing a Neo4J query or deploying a new microservice on Kubernetes. After lunch, you might review a colleague's PR for a new AI evaluation framework, then spend the afternoon researching best practices for reducing model bias in credential matching.
