Who We AreAtlan is building the missing context layer for data and AI, helping enterprises close the AI value chasm and finally move AI pilots into production. Today, 95% of AI pilots fail because AI systems don’t understand the context behind data: what it means, how it’s governed, and how it should be used.Atlan unifies this context by connecting to every part of the data and AI stack, enabling teams to build, collaborate on, and activate shared context across data, business, and AI workflows, including for AI agents.Trusted by global enterprises like Mastercard, Workday, General Motors, Unilever, Ralph Lauren, FOX, Nasdaq, and Medtronic, we’re backed by world-class investors including GIC, Insight Partners, Meritech, Peak XV, and Salesforce VenturesWhat will you do? 🤔We're looking for a Senior Cloud Security Engineer to join our Security team and play a critical role in securing Atlan's cloud infrastructure.
