Software Development Engineer, Ads Core Services

Build the real-time, globally distributed platform that controls billing, budgeting, payments, and promotions for Amazon Advertising — processing multi-million transactions worth 100x in dollar value daily with millisecond SLAs, directly impacting the experience of advertisers worldwide. Your work powers the financial levers behind one of Amazon's fastest growing businesses.

The Iron Mountain platform is the singular system managing all advertiser-facing financial functions — billing, invoicing, accounting automation, budgets, promotions, payments, and Billing Advertiser Experience (AX) — in real-time while being transparent and auditable from the ground up. These systems serve Sponsored Ads worldwide across all advertising displayed on or off Amazon. With international expansion driving 10X traffic growth, you'll solve critical distributed systems challenges: building architecture that scales exponentially, maintains high availability with minimal downtime (where outages directly impact revenue and advertiser business), and guarantees millisecond response times for front-end advertiser experiences. Our team spans Bangalore, Seattle, and New York — truly global in spirit.
