Senior Principal Engineer , AWS Billing

About the role

How cloud customers experience billing - from the pricing they see, to the costs they manage, to the bills they pay - is foundational to how they trust and grow with AWS. Today, that experience is ready for a transformation: one that brings the commercial simplicity of amazon.com to the cloud, in near real-time, across every customer segment. Are you ready to define the technical strategy that makes that possible?

Key job responsibilities

Define and own the multi-year technical strategy for billing architecture, partnering with engineering leaders and scientists across the organization to guide the next generation of billing systems - more composable, more adaptable, and built to evolve at the velocity the business requires.

• Drive architectural decisions that span multiple organizations across AWS service teams, Marketplace, Sales, and Finance, ensuring alignment on how billing systems transform from batch-oriented financial processing into a real-time platform.
• Provide technical guidance across billing and commerce teams, increasing productivity and effectiveness through deep knowledge of distributed systems, real-time processing, enterprise architecture, and generative AI technology.
• Ensure the quality of architecture and design across billing systems by decomposing complex problems into straightforward, scalable solutions, with a focus on performance optimization and engineering practices that enable systems to scale seamlessly.
• Mentor engineers and the broader community on advanced distributed systems challenges, helping develop technical talent across billing engineering teams while maintaining a pragmatic focus on business outcomes.

A day in the life

You will balance understanding the nuances of how customers - from startups to the world's largest enterprises - interact with AWS billing and cost management, while shaping the architectural vision that makes those experiences seamless.

On any given day, you may lead a design review for a next-generation pricing engine, align with partner teams on integration patterns for a new AWS service launch, or work hands-on with engineers to prototype a real-time billing pipeline. You will navigate competing stakeholder priorities while maintaining a high bar for accuracy, performance, operational resilience, and system efficiency.

You will also play a key role in shaping how the engineering organization leverages AI to accelerate development, testing, and delivery across the billing platform.
