• Build Scalable Pipelines: Design, develop, and optimize robust big data pipelines using Python, Apache Spark, and Apache Airflow.

• Cloud Infrastructure: Deploy and manage Spark jobs on Kubernetes (K8s/EKS) and utilize AWS services (S3, EMR, Glue, Athena) to build highly scalable data architectures.

• Ensure Security & Governance: Implement and maintain top-tier security standards across the Hadoop ecosystem and AWS infrastructure.

• Technical Leadership: Act as the ultimate technical authority on the project, mentoring senior engineers, driving best practices, and collaborating closely with stakeholders to meet RFP requirements.

• Modernize Data Formats: Implement and optimize data storage using Apache Iceberg.

Qualifications

• Extensive Experience (8+ years): Proven track record in data engineering with a focus on large-scale distributed systems and data migrations.

• Cloud Expertise (AWS): Deep knowledge of AWS data services, including S3, EMR, Glue, and Athena. Experience running Spark jobs on K8s or EKS is highly desired.

• Data Processing: Exceptional, hands-on experience with Apache Spark and strong programming skills in Python.

• Orchestration: Solid experience building and managing complex DAGs with Apache Airflow.

• Modern Table Formats: Production experience with Apache Iceberg.

• Security: Strong understanding and practical experience with Hadoop Ecosystem Security.

Would be a plus

• Hands-on experience with the legacy Hadoop stack (YARN, HDFS, Hive).

• Prior experience acting as a technical lead in enterprise-level Data Migration RFPs.

We offer

• Opportunity to work on bleeding-edge projects.

• Work with a highly motivated and dedicated team.

• Competitive salary.
