Senior Software Engineer, AWS Applied AI Solutions

We are seeking an exceptional Senior SDE to own the identity architecture at the foundation of this system. When an agent acts inside a user's desktop session, it inherits that user's identity. Every downstream system then attributes the agent's actions to the human. Solving this means deciding how agent identity is established, propagated across protocol and service boundaries, and preserved through to policy enforcement and audit. These decisions determine whether the rest of the governance stack — attribution, enforcement, approval, evidence — can be trusted at all. You will make foundational architectural calls, write code, mentor the engineers around you, and drive consensus with partner teams whose identity models were built for humans. This is a high-visibility, high-ownership role on a small team solving problems with no established playbook.

* Own the end-to-end identity architecture for agent governance: how agent identity is established, propagated, and preserved across desktop sessions, protocol boundaries, and downstream services

* Design attribution and audit systems that distinguish agent actions from human actions within the same session, at the infrastructure level where agents cannot tamper with the record

* Own policy enforcement architecture, including authorization models that evaluate agent actions before they execute

* Evaluate build-vs-leverage decisions across identity and authorization primitives, including assessments of existing internal and external components for reuse

* Drive technical consensus with partner teams whose identity and permission models predate autonomous agents

* Mentor and develop junior and mid-level engineers through code reviews and design reviews

* Communicate architectural decisions and tradeoffs to senior leadership and non-technical stakeholders
