Sr. Software Development Engineer, AWS Discounts

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 to enhance builder productivity

Key job responsibilities
Design and build distributed systems that apply discount logic at AWS scale - processing billions of usage events and generating discount line items across UBD, PRC, ABD, CSD, EDP, and other discount mechanisms
Build configuration-driven discount systems that allow sales, service, and finance teams to structure new discount constructs without requiring engineering changes
Enforce accuracy as a non-negotiable bar - every discount must be correctly applied, fully auditable, and traceable from contract terms to invoice line item
Partner with AWS sales, finance, and service teams (EC2, Marketplace, Bedrock, APN) to translate complex enterprise deal structures into scalable, durable billing constructs
Mentor engineers and raise the bar for code quality, operational excellence, and engineering rigor across the team
BASIC QUALIFICATIONS - 5+ years of non-internship professional software development experience
- 5+ years of programming with at least one software programming language experience
- 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
- Experience as a mentor, tech lead or leading an engineering team
PREFERRED QUALIFICATIONS - 5+ 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
- Experience building complex software systems that have been successfully delivered to customers
