Science Annotation Ops Analyst

Description
Are you passionate about building scalable data pipelines and dashboards that power machine learning innovation? Do you thrive at the intersection of data engineering, AWS cloud architecture, and automation? Join the Worldwide Returns, ReCommerce & Sustainability team where your technical expertise will directly support high-quality training data that fuels ML models—helping Amazon achieve zero waste, zero cost of returns, and zero defects.
As a Science Annotation Operations Analyst, you'll own end-to-end data pipelines that extract, validate, and consolidate annotation metrics from AWS and SageMaker. You'll build production dashboards, create custom annotation interfaces, and automate critical workflows—all while collaborating with Program Managers, Science Specialists, and cross-functional teams. This role offers you the opportunity to leverage Python, AWS services, and web development skills to solve real problems that impact both customers and the planet.
Key job responsibilities
Design and maintain scalable data pipelines that extract, parse, validate, and consolidate annotation metrics from AWS and SageMaker, ensuring data quality and auditability throughout the lifecycle
Build and operate production dashboards on EC2 covering the full data lifecycle (ingest, validate, score, publish) using technologies like Plotly Dash or Streamlit
Implement secure, least-privilege cross-account AWS integrations using IAM, STS, Lambda, and API Gateway to enable seamless data ingestion from multiple source accounts
Develop custom SageMaker Ground Truth labeling templates using HTML and JavaScript with conditional logic that transform written SOPs into validated annotation interfaces
Automate recurring manual processes including monthly consolidation, historical backfills, and scheduled jobs while maintaining alerting, backups, and deployment workflows to improve operational efficiency
A day in the life
You'll collaborate with Program Managers, Leads, and Science Annotations Specialists to tackle technical challenges that span the data lifecycle. You could start with debugging a Python script that processes annotation metrics with pandas and boto3, followed by deploying a new dashboard feature to EC2. Later, you could be writing SQL queries to validate data quality, configuring IAM policies for secure cross-account access, or building a new annotation UI template in HTML and JavaScript. You'll use Git for version control and Linux command-line tools to manage deployment workflows, all while serving as the technical POC for your team.
