About The Opportunity Our client, a leader in Enterprise Diagnostic Data and Technology, is looking for a skilled Sr. Data Engineer to join their team for a 7-month engagement. This project involves developing and maintaining the data systems and infrastructure that deliver diagnostic results to our customers in near-real-time. This is a high-impact role that requires a self-motivated professional who can hit the ground running and deliver results quickly. Key Responsibilities & Deliverables Streaming Data Pipelines: Build and maintain streaming ingestion, API-based data workflows, and distributed data transformations using AWS services (Kinesis, Lambda, Glue/Spark, EMR, S3). API Development: Develop and maintain REST APIs for data ingestion and consumption. Data Modeling: Develop and optimize data lake and operational data models for near-real-time use cases, supporting downstream loading into Snowflake.

Required Skills & Experience 3+ years of hands-on experience building production data systems or data services. Deep expertise in AWS for building applications, including services like Lambda, S3, API Gateway, IAM, Glue/Spark, and Kinesis. This is not a SQL/ELT or Databricks-notebook-driven role—you need to be a subject matter expert in building production systems. Solid proficiency in Python (and ideally Scala). Demonstrated ability to debug and reason about distributed data systems (streaming pipelines, Spark on EMR/Glue, APIs, queues, storage layers). Practical experience with infrastructure-as-code (Terraform or CloudFormation). Strong communication skills to provide clear and concise status updates to the project team.
