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.

You’ll take technical ownership of LLM‑powered features end‑to‑end, including architecture design, prompt engineering, context retrieval workflows, tool use, data privacy, guardrails, evaluation, and monitoring.

The ideal candidate knows how to efficiently iterate from prototypes to production‑grade solutions, thinks about end‑user experience and business goals, and loves learning and sharing knowledge.

You will contribute to AI expertise within the team and the company, and collaborate closely with senior engineers and other product and platform teams to build robust, well‑integrated solutions.

In this application‑layer role, you’ll work with existing foundational models rather than training custom ones.

As a Senior Software Engineer, you’ll also set and supervise technical direction, review other people’s designs, and help the team get better at using harnesses, code generation, and other AI tools for efficient development.
