Software Development Engineer , Leo Regulus

About the role

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. Leo Regulus is building autonomous AI agents that compress Amazon Leo's ecommerce launch lifecycle from months to minutes by executing in parallel, sharing cross-domain context, and learning from every launch.

Key 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

About the team

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.
