Original job description

Every time an advertiser runs a campaign on Amazon, they want to know: did it drive sales at Target, Walmart, Costco, and hundreds of other retailers? Omnichannel Metrics (OCM) answers that question - and we're just getting started. We build the ML-powered attribution systems that connect billions of ad impressions to real-world purchases across the entire retail landscape, processing massive-scale panel data to give advertisers measurement insights no competitor can match. OCM is one of Amazon Ads' highest-growth products, directly responsible for unlocking advertiser investment by proving the full omnichannel value of Amazon media.

Right now, we're shipping some of the most ambitious projects in MADS: Fine-Grained OCM that breaks attribution down to category and retailer level for the first time, OCM for Autos bringing omnichannel measurement to the automotive vertical, OCM Local building location-based foot traffic measurement for restaurants and retail, a Combined Methodology that unifies our Panel and Circana measurement into a single omnichannel view, and international expansion of the Unified Panel to 8 new marketplaces. Looking ahead to 2027, we're building real-time streaming attribution, integrating LLMs for agentic report generation and automated campaign optimization, expanding into healthcare and home services verticals, and launching causal incrementality measurement. The problems are genuinely hard - privacy-safe identity resolution at scale, calibrating ML models across sparse panel data, building streaming systems that produce daily estimates from weekly ground truth - and the ambiguity is high. You won't be handed a spec; you'll be defining what to build and how.

As an SDE II, you will own the architecture and delivery of major system components end-to-end. You'll make technology choices that shape how OCM scales from thousands to tens of thousands of active studies, design distributed data pipelines processing billions of events in Spark/EMR, and build the AI-powered features that transform OCM from a reporting tool into an autonomous measurement platform. You'll work across Scala, Java, and Python, with deep expertise in big data technologies (Apache Spark, Kestrel, EMR), AWS infrastructure (Lambda, DynamoDB, Step Functions, CDK), and data modeling for both relational and non-relational systems.

You will lead technical design reviews, mentor engineers, and raise the engineering bar across the team. You'll partner directly with applied scientists on ML model productionization and with product managers to translate ambiguous customer problems into scalable technical solutions. This is a team where an L5 engineer has outsized impact - we're small enough that your architectural decisions become the system, and high-visibility enough (S-team and VP-level goals) that leadership sees the results.

The ideal candidate thrives in ambiguity, has a track record of delivering complex distributed systems in fast-moving environments, and gets energized by problems that sit at the intersection of big data, ML, and product. You're not just looking for a job - you're looking for a team where you can shape the technical direction of a product that's redefining how the advertising industry measures success.

Key job responsibilities
- Design and build scalable data pipelines processing billions of ad impression and panel receipt events using Spark/EMR on Kestrel, powering omnichannel attribution for thousands of active advertiser studies
- Lead architecture decisions for OCM's calibration, report generation, and data processing systems spanning multiple pipelines across multiple AWS accounts
- Own end-to-end delivery of major product features - from technical design through production launch - including real-time streaming attribution, AI-powered report generation, and new vertical measurement frameworks
- Drive operational excellence across OCM's distributed systems: improve observability, eliminate silent failures, and build self-healing capabilities to meet advertiser SLAs
- Mentor junior engineers, raise the bar on code quality through design reviews and CRs, and establish engineering best practices across the team
- Partner with applied scientists and product managers to translate ML model requirements into production-grade systems that serve advertiser-facing measurement products

A day in the life
You might start your morning reviewing the overnight calibration pipeline run, investigating why a study's attributed sales look anomalous. After standup, you pair with an applied scientist to optimize a Spark job that processes panelist receipt data against ad exposure signals. In the afternoon, you lead a design review for a new streaming architecture that will reduce OCM's reporting latency from weeks to days. You close the day reviewing a CR from a teammate building LLM-powered receipt data extraction. Your work directly impacts how major brands like Procter & Gamble, Hasbro, and Scotts Miracle-Gro measure and optimize billions in advertising spend across Amazon and beyond.

About the team
Omnichannel Metrics (OCM) is part of MADS (Measurement, Ad Tech, and Data Science) within Amazon Ads. We answer the question every advertiser asks: "Did my Amazon ad drive sales at Target, Walmart, and other retailers?" Our team builds the ML-powered attribution systems that measure off-Amazon impact using panel data from millions of shoppers. We're a high-impact team in startup mode - shipping features that directly unlock advertiser investment and competing head-to-head with Google and Meta's measurement offerings. We value ownership, technical depth, and moving fast. Basic Qualifications: - 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
- Experience programming with at least one software programming language Preferred Qualifications: - 3+ 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
