Job Description
Aza is Amazon"s primary internal AI assistant, serving 1.5M+ employees globally across HR, IT, pay, benefits, and workplace domains. We"re not wrapping an LLM with a chat UI - we"re building a full-stack agentic platform: 60+ production sub-agents, multi-turn orchestration, real-time skill routing, MCP-based tool integrations, and enterprise-grade evaluation systems.
We"re looking for an SDE-II who wants to build AI-native systems from the ground up.
What makes this role unique:
- You"ll build the agent, not just use one. Aza 2.0 is built on Strands SDK with dedicated ECS Fargate compute, custom orchestration, and a plugin architecture spanning 60+ sub-agents. You"ll own real components of this system.
- Greenfield Gen AI engineering. We"re actively shipping: agentic inline workflows, voice-enabled agents, RAG pipelines, progressive skill loading, and a self-service developer platform for 50+ away teams building on Aza.
- Complex, high-stakes domain. Aza handles questions about pay, benefits, leave, HR policies - across every jurisdiction Amazon operates in. Correctness matters. This is where AI reasoning meets real-world constraints.
- Scale that doesn"t exist elsewhere. Millions of conversations monthly. Sub-3-second response latency. Production reliability with Sr. PE-level architectural standards.
- Visibility and mentorship. SVP-level visibility, Sr. PE driving architectural vision, and a fast-shipping team where engineers own end-to-end features in production.
Key job responsibilities
Design and build agentic systems: orchestration, skills, sub-agents, MCP tools, evaluation frameworks
Ship features end-to-end from design through production deployment
Work across the stack: LLM integration, distributed systems, real-time APIs, infrastructure-as-code
Collaborate with Sr. PE, PEs and Sr. engineers on architecture decisions that shape the platform"s future

It’s Always Day 1
At Amazon, it’s always “Day 1.” Now, what does this mean and why does it matter? It means that our approach remains the same as it was on Amazon’s very first day – to make smart, fast decisions, stay nimble, invent, and stay focused on delighting our customers. In our 2016 shareholder letter, Amazon CEO Jeff Bezos shared his thoughts on how to keep up a Day 1 company mindset. “Staying in Day 1 requires you to experiment patiently, accept failures, plant seeds, protect saplings, and double down when you see customer delight,” he wrote. “A customer-obsessed culture best creates the conditions where all of that can happen.” You can read the full letter here
