Sr.SoftwareDevelopmentEngineer,AWSDiscounts

The AWS Bill Generation – Discounts team is at the heart of how AWS rewards customer loyalty and drives long-term infrastructure commitments. We own and operate the billing systems that compute all discount-based derived line items for AWS customers worldwide — including Usage Based Discounts (UBD), Private Rate Card discounts (Flat PRC and Tiered UBTD), Cross-Service Discounts (CSD), Prepayment Discounts (DV), and Volume discounts (VPA). Our discounts are applied at both the service level (Service Specific Discount - SSD) and at granular service attribute levels (Attribute Based Discount - ABD), and are delivered through both Out-of-Cycle (OCB) and Anniversary bills. We also own CBAS (Config-Based Billing Automation System) — a solution we built to operationalize our largest and most complex customer contracts — and are actively driving its migration to scalable, standard discounting infrastructure. Our work directly impacts AWS's ability to close enterprise deals, retain strategic customers, and scale discount programs without engineering bottlenecks. As a Senior Engineer on the Discounts team, you will tackle the complexity challenge at the intersection of enterprise contracts, pricing flexibility, and billing accuracy. You will contribute to our roadmap focused on: * Flexibility & Time to Market — Building configuration-based billing infrastructure (BCD) that decouples discount definition from execution, enabling new pricing constructs to go live in days rather than months, and enabling complex discounts for strategic AI partnerships like Anthropic and OpenAI * Architectural Simplification - Consolidating Bill Compute tasks, and eliminating manual bill generation SOPs through automation * Customer Delight — Improving discount transparency, standardizing benefit-sharing features across regions, and reducing customer contacts related to discount charges * Operational Sustainability — Reducing Sev2s, accelerating deployment cycles through CI/CD, and leveraging AI t
