Software Engineer II, Leo Regulus

About the role

We are a team building the AI infrastructure that makes Amazon Leo's 100-country launch possible. Our entire stack is AI-native - every system we build either is an agent, powers an agent, or feeds an agent. We don't maintain legacy test frameworks or manual runbooks. We build autonomous systems and point them at problems that would otherwise require hundreds of engineers.

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
• 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
• 2+ years of Android development experience
• Amazon is an equal opportunity employer and does not discriminate on the basis of protected veteran status, disability, or other legally protected status.

Additional Information

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 -nwe 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. Export Control Requirement: Due to applicable export control laws and regulations, candidates 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.
