Senior AWS Data Engineer
Gdh Consulting, Inc.

Overview

We're seeking a senior-level data engineer to help design and build a modern AWS-based data lakehouse platform. This role is hands-on and suited for a "builder" who can stand up scalable patterns, work through evolving requirements, and partner closely with engineers, analysts, and data stakeholders.

What You'll Do

• Design data architecture (AWS lakehouse): Build scalable, reliable lakehouse solutions on AWS using Apache Iceberg and cloud-native services.
• Develop and operate data pipelines: Create, automate, and maintain ETL/ELT workflows to ingest data from multiple internal and external sources into AWS.
• Build data access services/APIs: Design and maintain secure, scalable RESTful APIs (and related interfaces) to enable data access for internal applications and teams.
• Implement AWS data services: Use services such as Amazon S3, EMR (Spark), Lake Formation, Lambda, API Gateway, and related tooling to support processing, storage, and analytics.
• Manage Iceberg tables on S3: Build and maintain Iceberg tables enabling ACID transactions, time travel, schema evolution, and lakehouse-style governance.
• Optimize performance: Apply partitioning strategies, compaction, file sizing, and tuning techniques to improve query performance and reliability.
• Ensure data quality and integrity: Implement validation, reconciliation, and error-handling processes to ensure consistent, trusted datasets.
• Security & compliance: Enforce strong access controls and governance (e.g., Lake Formation, IAM/Cognito authorization for APIs, encryption, least privilege).
• Collaborate and document: Partner with cross-functional teams and maintain clear technical documentation for pipelines, processes, and API specs.
• Support & troubleshooting: Provide technical guidance and issue resolution for pipeline operations and data/API endpoints.

Required Qualifications

• Bachelor's degree in Computer Science, IT, or related discipline (or equivalent experience).
• Strong experience in data engineering with significant hands-on work in AWS.
• Hands-on experience implementing Apache Iceberg (design, table maintenance, optimization).
• Proficiency in Python, Java, or Scala.
• Strong SQL skills (querying, modeling, schema design).
• Experience with big data processing using Apache Spark (EMR) and/or Hadoop ecosystem concepts.
• Experience developing and deploying RESTful APIs with attention to performance and security.
• Experience with orchestration tools such as Apache Airflow (or similar).
