Senior Engineer (AI Governance)

About StackOne: StackOne is the AI Integration Gateway for SaaS products and AI Agents. Backed by GV and Workday Ventures ($24M raised), we help builders of SaaS platforms and AI Agents orchestrate hundreds of scalable, accurate, and enterprise-grade integrations. Our platform combines 25,000 pre-mapped actions on 200 connectors, an AI-powered integration development toolkit, plus security by design: a real-time architecture, managed authentication and permissions, and end-to-end observability. Join us on our fast trajectory to build the future of agentic integrations. Own how enterprises govern the tools their agents can reach: the enrollment, provisioning, policy, posture, and identity-bound access layer that does for agent tooling what MDM and EDR (Jamf, Iru, CrowdStrike) do for devices, and what API gateways do for API traffic, at gateway scale. WHY THIS ROLE EXISTS StackOne is the tools gateway for agents: the secure, token-efficient layer through which AI agents reach 200+ enterprise SaaS systems. As enterprises connect agents to real tools and real data, governance becomes the defining problem: who or what may invoke which tool, with which scopes, against which data, under which conditions, and how you catch it when something drifts, misbehaves, or turns into a vulnerability. THE MENTAL MODEL What MDM, EDR, and identity platforms did for devices & software access, and what API gateways did for API traffic, applied to the tools agents use: - Enroll & inventory devices → register and inventory the tools agents can reach (servers, APIs, connected accounts) - Provision apps and configs to devices → provision agent and user access to specific tools and scopes - Compliance baselines and config profiles → policy for tool, scope, and data access, with conditional rules and guardrails - Authenticate, authorize, and rate-limit every API call (API gateway) → authenticate, authorize, and govern every tool call an agent makes through the gateway - Continuous posture and v
