Secure Every Identity, from AI to Human Identity is the key to unlocking the potential of AI. Okta secures AI by building the trusted, neutral infrastructure that enables organizations to safely embrace this new era. This work requires a relentless drive to solve complex challenges with real-world stakes. We are looking for builders and owners who operate with speed and urgency and execute with excellence. This is an opportunity to do career-defining work. We're all in on this mission. If you are too, let's talk. About Okta for AI Agents Okta secures access for 20,000 organizations and billions of users. Okta for AI Agents extends that work to the agentic shift. Deploying an AI agent is not like deploying traditional software. You are putting professional work output into production, and it needs deep integration, continuous tuning, and change management. Every agent needs an identity, a scope, an audit trail, and a way to be shut down when it goes wrong. Most enterprises have not built this yet. We are. We hire builders who see the cracks in enterprise agent identity that everyone else has learned to live with. The Role You are the most senior technical field authority for agent identity at Okta. Where a Senior FDE owns the outcome inside one account, you own the patterns that every account and every FDE inherits. You take the hardest and most strategic deployments yourself, set the reference architecture the team builds from, and turn what the field learns into the direction the product takes. You still write code. You also multiply the people around you, and you are the person product and engineering leadership call when an agent identity problem has no precedent. Responsibilities Own the reference architecture. Define the canonical agent identity, delegation, audit, and kill-switch patterns that Senior FDEs deploy across the portfolio, and keep them current as the standards and the product move. Lead the hardest accounts. Personally own the most strategic, regul

About the role Almost every company can now produce training video at scale. Almost none of them can tell you whether any of it made someone better at their job. We're building the product that closes that gap: an agentic, real-time experience where people practice live, dynamic scenarios, and where organisations finally get signal on genuine readiness instead of a simple metric tied to course completion. This is a 0-to-1 bet on what comes after content, which is practice, and proof. You'll own a domain within it from strategy to ship. Why now: Real-time, agentic AI has only just become good enough to hold a convincing live scenario. The window to define this category is open now, and we intend to own it. The problem you're solving Today, the most you can do to assess whether someone has genuinely learned something is watch them complete a module or pass a quiz. The behaviours that matter in real roles, in real moments, are rarely tested reliably. We have the underlying technology to change that. What we need is a PM who can turn that into a product that an enterprise will use to prepare their people, and that a end user actually wants to engage with.
