Lead Big Data Developer

The primary business objective of this project is to modernize and scale the enterprise data platform by migrating the existing on-premises HDFS and Hive-based ecosystem to a cloud object storage solution.

This transition aims to reduce infrastructure maintenance overhead, improve scalability, and support advanced analytics through Apache Iceberg, which offers improved performance, versioned datasets, and native compatibility with modern data processing engines.

Responsibilities

• Lead and mentor a team of data engineers, providing technical direction and career guidance.
• Define the target data platform architecture for migrating from on-prem HDFS/Hive to Cloud Object Storage (e.g., AWS S3, Azure Data Lake Storage, or GCP Cloud Storage).
• Select and integrate cloud-based compute and query engines (e.g., Spark).
• Lead the design of ingestion, transformation, and storage patterns optimized for scalability, cost-efficiency, and performance in the cloud.
• Define security, encryption, and compliance controls for sensitive enterprise data in the cloud.
• Develop and own the migration roadmap, including phased transition from on-prem to cloud while minimizing business disruption.
• Oversee data migration strategies (bulk historical loads, incremental sync, and cutover).
• Define and enforce coding standards, CI/CD pipelines, and automated testing for data pipelines.
• Partner with Data Architects, Cloud Engineers, and Security teams to align platform design with enterprise standards
  
  

Requirements

• Proven experience leading data engineering teams, including distributed teams across multiple geographies and time zones.
• Effective in managing cross-team collaboration with architects, product managers, and operations.
• Knowledge of Scala and Python
• Experience with Apache Spark (batch & streaming)
• Deep knowledge of HDFS internals and migration strategies.
• Experience with Apache Iceberg (or similar table formats like Delta Lake / Apache Hudi) for schema evolution, ACID transactions, and time travel.
• Running Spark and/or Flink jobs on Kubernetes (e.g., Spark-on-K8s operator, Flink-on-K8s).
• Experience with distributed blob storages like Ceph or AWS S3 and similar
• Building ingestion, transformation, and enrichment pipelines for large-scale datasets.
• Infrastructure-as-Code (Terraform, Helm) for provisioning data infrastructure.
• Strong communication skills
• Availability to join evening calls (till 21:00 EET)
  
  

Nice to have
