WHAT WE ARE LOOKING FOR

Tealium is expanding its Insights engineering team with a Senior Software Engineer to help design and implement scalable production systems and AI agents built on large language models. The team is focused on building Tealium products that provide analytics, recommendations, AI-assisted decision-making, and workflow automation for our customers.
