• Implement backup, restore, and cross-region replication strategies
• Manage raw data storage over S3 and apply lifecycle policies

Transactional & Search Database Tuning:

• Optimize sql / no-sql databases
• Maintain petabyte-scale Elasticsearch clusters:
• Design index templates, shard/replica allocation, and rollover policies
• Tune analyzers, mappings, and relevance scoring for low-latency search
• Monitor cluster health and perform rolling upgrades with zero downtime
• Automate database maintenance tasks (vacuum, analyze) and monitor slow queries

ETL Development & Data Migrations:

• Architect, build, and maintain batch and streaming ETL pipelines using EMR/Spark, Glue, Lambda, and Delta Lake
• Lead large-scale data migrations (S3/HDFS ingestion, Redshift migrations, cross- cluster reorgs) with minimal downtime
• Ensure idempotency, data quality, and rollback strategies in all migration workflows

Big Data Storage & Pipeline Maintenance:

• Manage data lakes on S3 and HDFS; implement Delta Lake for ACID transactions and schema evolution
• Oversee EMR/Spark pipelines, ensuring reliability and performance at scale
• Leverage ECS/Fargate for containerized data workloads and ad-hoc processing

Metadata & Governance:

• Manage Glue Data Catalog and Lake Formation permissions
• Establish data lineage, schema version control, and audit processes
• Manage data lifecycle and data governance

Innovation & Technology Research:

• Evaluate and pilot emerging large-scale storage technologies (Apache Iceberg, Hudi,Redshift RA3 & AQUA)
• Prototype next-generation data architectures (data mesh, lakehouse patterns)
• Develop PoCs for modern query engines (Redshift Spectrum, Athena fanning out to

1. Iceberg tables)

Cross-Functional Collaboration & Mentorship:

• Partner with DevOps and Security to enforce IAM roles, encryption (KMS), and network isolation
• Mentor DE II engineers on modeling best practices, ETL patterns, and database troubleshooting
• Champion adoption of new tools and frameworks across the Data Engineering team

What You'll Need:

• 5+ years of hands-on experience in data modeling, ETL development, and database administration
• Deep expertise in dimensional modeling (star/snowflake) and normalization trade-offs
• Proven track record managing Amazon Redshift, PostgreSQL, and Elasticsearch at scale
• Strong experience building and migrating ETL pipelines (EMR/Spark, Glue, Lambda, Delta Lake)
• Proficiency with S3/HDFS architectures and data lake best practices
• Excellent SQL skills and proficiency in Python or Bash scripting
• Demonstrated success in large-scale data migrations with minimal business impact
• Strong communication, documentation, and mentoring abilities

Preferred Qualifications:

• AWS certifications (e.g., Database – Specialty, Big Data – Specialty)
• Experience with additional NoSQL systems (DynamoDB, Cassandra)
• Knowledge of data mesh or data fabric architectures
• Background in DevOps practices (CI/CD for schema and ETL code changes, Terraform/CDK)

Why You'll Love Working Here:

• Shape the backbone of our analytics and ML platforms by leading both modeling and ETL efforts
• Influence data governance, migration strategy, and best practices across the organization
• Competitive compensation, comprehensive benefits, and flexible work options
