Software Engineer II, Leo Regulus

Amazon • Redmond, WA

8d • $143,700 - $194,400 • Onsite

About The Position

Amazon Leo is launching satellite-based connectivity in 100+ countries. Every country launch requires validation across tax, accounting, disbursement, legal, trade, and core commerce — thousands of test cases, dozens of teams, months of sequential human work. We're replacing that entire process with orchestrated AI agent squads that execute in parallel, share cross-domain context, and learn from every launch. Leo Regulus is an AI-native team building autonomous agents that compress Amazon Leo's ecommerce launch lifecycle from months to minutes. We don't write test cases — we build agents that write, execute, diagnose, and remediate them. We don't configure financial systems — we build agents that learn accounting rules and produce correct configurations. We don't coordinate cross-team handoffs — we build agents that do it for each other.

Requirements

• 3+ years of non-internship professional software development experience
• 2+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• 2+ years of full stack development experience
• Must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Nice To Haves

• 3+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• Bachelor's degree in computer science or equivalent

Responsibilities

• Design and build autonomous AI agents that execute end-to-end ecommerce validation without human intervention
• Build orchestration systems that coordinate dozens of domain-specific agents working in parallel
• Create knowledge base architectures that ground agent behavior in accounting, tax, and compliance rules
• Solve novel problems at the intersection of AI, distributed systems, and financial domain complexity
• Designing, building, and operating autonomous AI agent systems that automate the end-to-end ecommerce launch lifecycle — from requirements generation through financial configuration, test execution, and validation — enabling Amazon Leo to scale country and feature launches across 100+ markets without proportional headcount growth.
