Job description

Location: Wilmington, DE Description:
Job Title: Senior Java Data Engineer (AWS)
Job Overview
We are looking for a Senior Java Data Engineer with strong experience building and supporting large-scale batch data processing systems on AWS. This role focuses on ETL-style data pipelines, data warehousing concepts, and high-volume analytics platforms. The ideal candidate is a hands-on engineer who can independently debug complex issues and work closely with analytics, risk, and platform teams.
This is not a real-time or streaming role-the environment is heavily batch-oriented.
Key Responsibilities
  • Design, develop, and maintain Java-based batch data processing applications
  • Build and support ETL pipelines operating at scale in AWS
  • Work extensively with AWS EMR for distributed data processing
  • Develop and maintain integrations using:
    • Amazon S3
    • AWS Glue (Glue Tables)
    • AWS Athena
    • AWS Lambda (where applicable)
  • Debug and resolve complex production issues independently
  • Support data warehouse-like environments and analytical workloads
  • Collaborate with analytics, fraud risk, and platform teams to ensure data accuracy and reliability
  • Improve operational efficiency through automation
  • Leverage AI productivity tools (e.g., GitHub Copilot) responsibly to improve development quality and reduce risk
  • Follow engineering best practices for reliability, scalability, and compliance

Minimum Qualifications (Must Haves)
  • Strong hands-on Java development experience
  • Solid experience working with AWS, specifically:
    • Amazon S3
    • EMR (primary and heavily used)
    • AWS Glue (Glue Tables)
    • AWS Athena
    • AWS Lambda
  • Proven experience with batch processing systems (non-real-time)
  • Strong debugging and troubleshooting skills with the ability to work independently
  • Experience building ETL-style data pipelines
  • Background working in data warehouse or analytics platforms

Preferred Qualifications (Nice to Haves)
  • Experience with Apache Spark or Java Spark
  • Exposure to Snowflake (basic understanding required; deep expertise not expected)
  • Experience with automation frameworks or tooling
  • Exposure to AI-assisted development tools (e.g., GitHub Copilot or similar)
  • Experience with Terraform (currently used, though being phased out)
  • Background supporting fraud risk, financial data, or analytics platforms
  • Awareness or prior exposure to PySpark (acceptable, though role is Java-focused)
