Python Junior Jobs in Seattle, WA (NOW HIRING)

Are you passionate about building data infrastructure that powers real-time logistics decisions for millions of customers? The Global Transportation Services (GTS) Speed team is looking for a Data Engineer II to own critical data pipeline components that drive delivery speed optimization across Amazon's transportation network.
In this role, you will independently design, build, and operate scalable data infrastructure solutions that integrate with multiple heterogeneous data sources. You will own end-to-end pipeline development - from extraction and transformation to loading and serving - ensuring data is delivered reliably and efficiently for reporting, analysis, and machine learning workloads. You will manage multiple Redshift clusters supporting the transportation organization's reporting needs, make technical decisions on data modeling and architecture for your domain, and collaborate with cross-functional teams to translate business requirements into high-impact data solutions.
Key job responsibilities
- Own end-to-end design, development, and operation of ETL/ELT pipelines that extract, transform, and load data from diverse sources using SQL, Python, and AWS big data technologies
- Manage and optimize multiple production Redshift clusters, including performance tuning, capacity planning, and cost optimization to support transportation org reporting needs
- Lead technical design discussions with Product teams, Data Scientists, Software Developers, and Business Intelligence Engineers to define data infrastructure requirements and deliver scalable solutions
- Define and enforce data engineering best practices for your domain, including code quality standards, testing frameworks, documentation, and deployment processes
- Conduct thorough code reviews and mentor junior data engineers on technical problem-solving, coding standards, and AWS best practices
- Proactively identify and resolve scalability bottlenecks, re-designing infrastructure for greater reliability and performance
- Evaluate emerging AWS technologies and lead proof-of-concept efforts to enhance data platform capabilities
- Own production operations including release management, incident response, and continuous improvement of data delivery systems
A day in the life
You start your day reviewing pipeline health dashboards and resolving data quality issues. You collaborate with data scientists and business leaders to translate their requirements into technical solutions. During high-volume periods like Prime Week, you ensure pipelines support real-time decision-making for delivery network optimization. You spend time writing and reviewing code, optimizing query performance, and mentoring teammates on best practices. You also evaluate emerging technologies - building proof-of-concepts for intelligent data discovery and automated solutions that reduce manual effort and enable stakeholders to access insights independently.
