Job Description/ Responsibilities

1. Identity & Entitlements: Integrate the API layer with AWS IAM Identity Center (IdC) and build a policy engine to enforce data boundaries (SRE vs. App Team vs. Business Unit). This includes integrating Omni into the client's existing identity-federation model - an established custom credential-vending / SAML broker on the primary landing zone plus existing IdC adoption for console access.

2. Cross-Account Data Routing: Implement and automate links to aggregate logs, metrics, and traces across multiple AWS Organizations.

3. End-to-End Feature Delivery: Build, test, and deploy features from the AWS infrastructure layer (CloudWatch / Omni / IAM) up through the API layer that serves the UI, using CloudWatch cross-account capabilities. May include writing high-performance APIs (in Go, Python, or Java) to query CloudWatch, CloudTrail, and flow logs, and implementing efficient caching strategies.

4. Infrastructure as Code (IaC): Automate the deployment of all resources using Terraform or AWS CDK, leveraging AWS CloudFormation StackSets to deploy source links to 15,000 accounts.

5. Enablement: Produce clear architecture and integration documentation and enable the client's teams to operate and extend the Omni identity and routing model, working as an embedded SME alongside the client's SRE and observability leadership.
