AWS Data Engineer - II

Responsibilities

• Lead the next phase of the healthcare data platform modernization
• Implement the evolution from a Microsoft SQL eXtensible Markup Language (MSSQL XML) object store toward a scalable, cloud-native AWS data architecture that enables business stakeholders and analysts to run performant, SQL-based reports and queries against healthcare data seamlessly
• Evaluate and decide the right AWS data strategy for the platform
• Evaluate and recommend the optimal AWS-native data storage and query architecture for the XML object store data, assessing options such as S3 + Athena, Aurora, DynamoDB, Redshift, and OpenSearch based on query patterns, reporting needs, cost, and scalability
• Design and build the reporting and query layer that allows business stakeholders and non-technical users to run relational SQL queries against healthcare data using familiar tooling
• Architect the migration path for XML object store data from MSSQL into the target AWS platform, defining storage formats, partitioning strategies, and data organization for optimal query performance
• Build and maintain AWS data catalog, schemas, and metadata management so that object store data is discoverable and queryable by business users
• Optimize query performance and cost across chosen AWS services – partitioning, compression, file formats, and query pattern tuning
• Work directly with business stakeholders and analysts to understand reporting requirements and translate them into durable, performant data models and query patterns
• Collaborate with back-end C#/.Net engineer to ensure data flows cleanly from Electronic Data Interchange (EDI) processing pipelines into the new data layer
• Implement and maintain CI/CD pipelines for data infrastructure using AWS-native tooling (CodePipeline, CodeBuild, and CodeDeploy)
• Apply Infrastructure as Code (IaC) practices using AWS Cloud Development Kit (CDK), CloudFormation, or Terraform
• Document architecture decisions, data flows, and data dictionaries clearly for both technical and non-technical audiences

Requirements

• 8+ years’ experience in software or data engineering with a strong AWS focus
• Bachelor’s degree or higher in Computer Science, Engineering, or a related technical discipline; equivalent practical experience considered
• U.S. Citizenship required for this specific opportunity
• Must possess or qualify for a Public Trust (MBI) security clearance

Skills

• Proven experience architecting and executing cloud data platform migrations in production enterprise or healthcare environments
• Track record of evaluating and selecting AWS data services to meet business reporting and query requirements
• Experience delivering reporting or analytics solutions that serve non-technical business users
• Deep hands-on AWS experience across data-oriented services – S3, Athena, Glue, Aurora, DynamoDB, Redshift, OpenSearch, Lambda, IAM, and Cloudwatch
• Strong SQL skills with the ability to design relational query layers over semi-structured or non-relational data (XML, JSON)
• Experience working with XML-heavy data stores – parsing, querying, and transforming XML at scale
• Ability to evaluate trade-offs across AWS data services and
