About The Role As a Full Stack Engineer on the Agent Passport & Assurance team, you’ll build the user-facing and platform experiences that make AI agents trustworthy, observable, and governable. Agentic AI is moving into HR and Finance workflows, and enterprises need to know what their agents are doing, what they’re allowed to do, and whether they can be trusted. That’s the problem we’re solving. Agent governance and security is a new and fast-evolving field. There is no established playbook, so you’ll help define it. You’ll work in a small, cross-functional pod to design and ship full stack solutions, from intuitive front-end experiences to resilient backend services that cover runtime guardrails, policy enforcement, agent inspection, evaluation, and red teaming. You’ll collaborate closely with machine learning engineers, product managers, security partners, and platform teams, owning features end to end and seeing your work run in production. If you enjoy building real products, solving problems with no existing answer, and working with people who care about quality and craft, you’ll feel right at home here.

Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in-office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you'll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together.
