As agents become the primary interface for advertisers and partners, we need infrastructure that gives every agent a unique identity, scoped permissions, and a complete audit trail - while giving advertisers full control over what agents can do on their behalf. This is a new strategic investment area and we're assembling the team., Design and build authorization infrastructure that evaluates agent permissions at the API layer, enforcing capability-scoped access in real time at low latency and high availability. - Own the technical vision for agent authentication flows including delegation mode, autonomous mode, and machine-to-machine auth with short-lived tokens. - Build the agent registry system that issues unique identities to 1P and 3P agents, captures declared capabilities, and integrates with downstream enforcement. - Design agent-to-agent delegation protocols including scoped tokens and chain-of-trust verification. - Drive operational excellence across Tier-1 services handling millions of authorization decisions daily. Influence the broader system architecture across 10+ dependent teams, ensuring authorization integrates cleanly with the Ads Agent platform. - Use AI-powered development tools daily to accelerate your own engineering work. A day in the life You might start the morning reviewing a design for how 3P agents authenticate under their own identity rather than borrowing a user's OAuth token. Mid-morning you're in a design review with the Ads Agent Orchestrator team, aligning on how capability-scoped permissions get enforced when an agent invokes MCP tools. After lunch you're writing code - building the authorization decision engine that evaluates whether "PacVue Bid Optimizer" can adjust bids on advertiser X's campaigns but not touch their creative assets. You close the day pairing with a teammate on load testing the new memcached cluster that needs to handle 400K+ accounts post-backfill without degrading latency. Your stakeholders include the Ads Agent platform team, Developer Experience (DX), partner-facing teams, and 3P integrators like PacVue and Teikametrics who are building agents on our platform. You'll work closely with the PMT defining the product and the SDM leading the team. About the team The Ads Agent Identity and Authorization Infrastructure (AI²) team owns identity and access management for Amazon Ads - for both humans and AI agents. We manage registration, account management, permission controls, and ad-product eligibility serving 5K+ partners and 2M+ advertisers globally with 800K+ registrations per year. We shipped agent registry and agent authorization for 1P agents in Q1 2026 and are now extending to 3P. We are a team that ships fast, uses AI tooling in our own workflows, and operates with founding-team energy backed by Amazon Ads scale. We're based in New York (JFK19). ## Related Videos - [Fireside Chat - In conversation with Werner Vogels, CTO of Amazon.com](https://www.wearedevelopers.com/videos/100265-fireside-chat-in-conversation-with-werner-vogels-cto-of-amazon-com) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Resilient by Design: Building Robust Architectures in High-Stakes Financial Systems](https://www.wearedevelopers.com/videos/2106-resilient-by-design-building-robust-architectures-in-high-stakes-financial-systems) - [Are Code Reviews Worth It?
