Senior Financial Analyst , S3​/Glacier Finance

AWS Web Services is a highly reliable, scalable, low‑cost infrastructure platform in the cloud that powers hundreds of thousands of enterprise, government and start‑up businesses and organizations in over 190 countries around the world.

• Driving financial planning & analysis; building complex financial models and analytical tools to support review of S3's costs and capacity
• Developing short and long range financial / operational forecasts of S3's infrastructure footprint
• Develop, track, and report relevant KPIs to shed financial and operational insights into the Cap Ex and OpEx drivers, and influence business decisions using data and communication skills
• Driving ad hoc financial analyses and projects

Your day revolves around cross‑functional collaboration—partnering with engineering, finance, and operations teams to align capacity planning with business objectives while tracking actual usage and Cap Ex spend against plan. You'll spend significant time in meetings and discussions, translating complex technical requirements into financial implications, monitoring variances between forecasted and actual consumption, and communicating trade‑offs to stakeholders. You'll quickly digest and process technical changes to AWS infrastructure to materialize those in financial impact, including investment returns, risk exposures, and discovering potential saving opportunities to provide business teams with meaningful and actionable recommendations.

Throughout the day, you'll coordinate approval workflows, analyze spending trends, provide guidance to team members, and dedicate time to learning AI tools and other internal systems for continuous improvement, driving automation to enhance team efficiency.

The S3 Finance Cost and Capacity Team supports one of AWS's most critical foundational services, directly impacting not only S3 but also driving cost implications across the entire AWS ecosystem. As a high‑profile team working on a service that continues to experience rapid growth, we sit at the strategic intersection of finance, engineering, and operations—translating infrastructure decisions into business impact at massive scale.

Our work influences rack and server landings, procurement strategies, commercial deals, and supports new product pricing decisions. We drive multi‑billion dollar capacity investments and cost optimization opportunities that ripple across AWS services, partnering with engineering and business teams to ensure S3's continued success while maintaining financial discipline in one of the cloud industry's most important and fastest‑growing services.
