Amazon Leo Productivity Infrastructure & Engineering (ALPINE) owns and operates the core enterprise infrastructure that enables Amazon Leo's 7,000+ engineering workforce to design, build, test, and ship software. Our portfolio spans Atlassian, SAP, Engineering Test Platforms, Requirements Management, and a License Server Fleet deployed across commercial AWS Gov Cloud environments.

We are looking for a Senior Systems Development Engineer to serve as a senior technical contributor across ALPINE‑managed services while driving AI integration readiness. You will own infrastructure reliability, scalability, and security across our service portfolio while designing and building the interfaces and APIs that allow AI agents to interact with these services safely and at scale.

This role combines deep infrastructure ownership with forward‑looking platform engineering — maintaining Tier‑1 services today while building the foundation for AI‑powered engineering workflows. You will operate within AWS Gov Cloud under FedRAMP High requirements and partner with Amazon Leo Security and Global Trade & Compliance teams.

Own and operate infrastructure across ALPINE's service portfolio, ensuring availability, performance, and security for Tier‑1 services

Design and deploy integration interfaces that expose ALPINE services to AI orchestration layers

Implement authorization controls ensuring AI agents operate within user permission boundaries

Drive infrastructure‑as‑code improvements, pipeline modernization, and deployment standardization across commercial and Gov Cloud environments

Harden workloads with security best practices including network segmentation, TLS enforcement, and minimal‑privilege configurations

Implement authentication and policy enforcement at the integration layer

Participate in on‑call rotations; own operational excellence including runbooks, monitoring, and incident response

Collaborate on architecture reviews, threat modeling, and security compliance reviews

Build and maintain CI/CD pipelines with integrated security gates

Produce architecture documentation and integration specifications

Identify and drive operational improvements through automation and improved observability

Your morning starts with the ALPINE operational dashboards; triaging overnight alarms, verifying AI‑initiated queries respected classification retrieval gates, and confirming deployment pipeline health across the fleet. From there you shift into building: writing CDK to stand up a new MCP server, implementing token flows for transitive authorization, troubleshooting a canary failure caused by a certificate rotation, or designing cross‑partition data paths that satisfy both network segmentation and AI‑platform access requirements.

The afternoon might find you in a design review sketching out how to safely expose SAP transaction data to the AI orchestration layer, rolling out a shared CDK construct across multiple Atlassian deployments, updating runbooks, or reviewing a teammate's PR for a new MCP integration. Every day spans the full stack; keeping Tier‑1 production services healthy while building the connective tissue for AI‑powered engineering workflows.

You will join the ALPINE "Jedi Council," a small group of senior engineers who collectively own the technical direction and operational health of the entire ALPINE service portfolio. The team operates as a collaborative technical council rather than a traditional hierarchy; each member…
