Amazon Ads Tech SDE2 building low-latency, high-concurrency customer search widgets and scalable AWS data/ML pipelines.
IndiaWhat I'm looking for
I build and ship customer-facing search widgets at Amazon Ads Tech in Sponsored Products, leading end-to-end development with Java/Springboot and AWS services like EMR and Sagemaker. I’ve scaled these systems for peak traffic during Diwali windows and owned data generation by reverse-engineering missing SOPs and coordinating across ML and platform teams.
I designed a reusable Apache Spark framework on AWS EMR to remove a dependency on Science-owned pipelines, and I expanded widget rollouts across multiple emerging markets using Sagemaker Theme Model service plus Java-based service integrations. I also architected migrations using Scala and Spark on MWAA to optimize for cost and latency while keeping data consistent.
I’ve built Media History and CI/CD and integration testing frameworks, cutting review time and reducing on-call incidents. I’ve been a primary on-call contributor, resolving 100+ production incidents across EMR jobs, Step Functions, and backend services, and mentoring SDE1s and interns as I promoted to SDE2.
