Senior Software Engineer, Billing Data Services

We make AWS billing data trustworthy at the source. As a Software Development Engineer II on the Billing Data Services (BiDS) team, you will build and operate the foundational systems that capture, store, and serve the billing facts that AWS billing services rely on.

Our services sit upstream of bill computation systems. We ingest billing data from across AWS (such as pricing, subscriptions, and entitlements), persist it as a single source of truth, and serve it to the teams and pipelines that join it with usage to synthesize customer-facing billing artifacts. We operate at the scale of all of AWS, where correctness is non-negotiable and a single bad record can ripple into thousands of customer bills.

As a senior software engineer on this team, you will lead the technical direction for large-scale distributed systems built on AWS services. You will design durable storage and serving paths, and build the data layer that hundreds of AWS teams depend on. Your work will impact millions of external customers and sit on the critical path of Billing.

Key job responsibilities
- Design high-quality, efficient, and testable code in Java and other object-oriented languages.
- Build large-scale, highly available distributed systems for ingesting, storing, and serving authoritative billing data at the scale of all of AWS.
- Design storage and serving paths that meet demanding freshness, accuracy, and latency requirements for downstream billing pipelines.
- Partner with downstream teams on schema and data contract changes, making sure migrations are backward compatible and do not disrupt their pipelines.
- Own and operate the systems you build, holding a high bar for data quality, correctness, and operational rigor.
- Contribute to planning, design, implementation, testing, operations, and process improvement as a member of a Scrum team.
- Collaborate with product managers and engineers across Commerce Platform teams to deliver features and drive the adoption of best practices.

A day in the life
You might start the morning reviewing ingestion and data quality dashboards before joining a design review for a new storage or serving path. By midday, you are working with a downstream team on a schema or data contract change, making sure the migration is backward compatible and won't disrupt their pipelines. In the afternoon, you are deep in an approach to cut serving latency or raise ingestion throughput, then aligning with a partner team on an upstream event format change. You balance long-term platform investments with the immediate needs of the teams that depend on your data.

About the team
We own the systems that hold and serve the authoritative billing facts for AWS Commerce Platform services. BiDS delivers timely and consistent operational billing data to support near real-time bill computation and cost and usage monitoring for AWS, giving billing teams a high-performance, queryable, and cost-effective data layer to store and access operational billing data.

Because we sit upstream of the bill computation systems, our data quality and freshness affect SLAs for the systems downstream. We treat correctness and operational rigor as first principles, but we move quickly when downstream teams and customers need us. We solve problems at the intersection of large-scale data systems, durable storage, and the trust customers place in their bill. This is a space where being right matters more than anything, and where the data we own touches every Billing team.
