Software Development Engineer, AWS Billing console platform

About the role

The AWS Billing Console Platform team owns the platform, the customer-facing pages, and the data deliverables that AWS customers use to manage their cloud spend. A 2026 reorganization consolidated the surface of three teams onto this one, so we operate at real scale: dozens of customer-facing pages, more than a hundred deployment pipelines, and a production footprint we are actively driving toward lower operational load through automation and legacy-service decommissioning. At the same time we are one of the teams defining how generative AI reshapes the billing console, building the agent interfaces and generated experiences customers will rely on next. That combination, a large operational platform plus a green-field AI mandate, means an engineer here can take on scope quickly and see a clear path to the next level. We operate what we build, hold a high bar for operational excellence, and care about inclusion, mentorship, and work-life harmony, so engineers at every level can do their best work and grow their careers.

Requirements

• 3+ years of non-internship professional software development experience
• 2+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• 1+ years of software development engineer or related occupational experience
• 1+ years of designing and developing large-scale, multi-tiered, multi-threaded, embedded or distributed software applications, to
• design, build, test, and operate billing and cost management services and console experiences used by millions of aws customers.
• build generative-ai cost-management experiences: agent-invokable skills, agent-instrumented console pages, and generated ui, measured against accuracy and customer-outcome bars the team sets.
• deliver contractual cost and usage data exports against strict specifications and timelines.
• help scale a platform that absorbed the operational surface of three teams in a 2026 reorganization: drive down operational load through automation, observability, and legacy-service decommissioning so the team can invest more in new customer experiences.
• own services end to end, including participation in the team's on-call rotation for production support.
• raise engineering quality through design reviews, code reviews, automated testing, and operational excellence, and partner with product managers, designers, and engineering teams across aws billing.

Additional Information

AWS Billing and Cost Management builds the experiences every AWS customer uses to understand, monitor, and optimize what they spend, from individual developers to enterprise FinOps teams managing tens of millions of dollars in monthly spend. The AWS Billing Console Platform team owns the console's hosting platform, its customer-facing billing and cost pages, and the contractual cost and usage data deliverables AWS owes its enterprise customers. The console is at an inflection point. AI agents, Amazon Q and customer-built agents over the Model Context Protocol, are beginning to mediate how customers do their billing work, and this team builds the platform that lets them: the agent-facing interfaces, the generated experiences a customer gets by stating intent, and the human-facing pages underneath. The long-term shape of the console in an agent-mediated world is still being written, and this team is writing it. We are hiring a Software Development Engineer II to help build it. The role starts by delivering a contractual cost and usage data export under strict compliance and delivery requirements, then expands across the team's full surface: customer-facing pages used by millions of AWS customers, the generative-AI cost-management experiences the team is standing up, and the platform that hosts them. You will own services end to end, from design and code through deployment and operations. This position requires that the candidate selected be a U.S. citizen. Key job responsibilities * Design, build, test, and operate billing and cost management services and console experiences used by millions of AWS customers. * Build generative-AI cost-management experiences: agent-invokable skills, agent-instrumented console pages, and generated UI, measured against accuracy and customer-outcome bars the team sets. * Deliver contractual cost and usage data exports against strict specifications and timelines. * Help scale a platform that absorbed the operational surface of three teams in a 2026 reorganization: drive down operational load through automation, observability, and legacy-service decommissioning so the team can invest more in new customer experiences. * Own services end to end, including participation in the team's on-call rotation for production support. * Raise engineering quality through design reviews, code reviews, automated testing, and operational excellence, and partner with product managers, designers, and engineering teams across AWS Billing. A day in the life You start by checking the health of the services you own and clearing anything handed off from on-call, then pick up your current project: maybe an agent skill you are building, where you run its responses through the team's evaluation framework, read where it falls short, and tune the approach. Midday you review a teammate's code, then join a design review where the team weighs a proposed agent experience against customer data before committing to build it. In the afternoon you pair with a product manager on the next milestone and sketch the design for an agent-instrumented page. Across the week you balance net-new AI and platform work against the operational excellence that billing customers depend on, and rotate through on-call. The problems are open-ended, the customer scale is large, and the design space is genuinely new, so there is room to set technical direction and grow into more scope. You will have the support of an experienced team and a manager invested in your growth.
