[Hiring] Senior Data Integration Engineer @EPAM Systems

Role Description

We are seeking a highly skilled, solution-oriented Senior Data Integration Engineer with deep expertise in modern data engineering, cloud-native architectures, and robust pipeline development. In this role, you will be a senior technical driver in creating, optimizing, and modernizing advanced data integration systems. You will collaborate closely with product, engineering, and architecture teams to bridge raw source environments and analytical databases. If you excel in cloud ecosystems, thrive on automating complex data workflows, and value precision, reliability, and data quality above all, we encourage you to apply!

Responsibilities

• Pipeline Architecture & Development: Design, build, and optimize scalable, reliable batch and near-real-time ETL/ELT pipelines using Python, PySpark, SQL, and modern cloud integration engines.
• Orchestration & Automation: Develop and manage complex workflow orchestrations (using Apache Airflow or cloud native schedulers) and automate ingestion routines to minimize manual operations.
• Data Modeling & Warehousing: Design and implement modern data warehouse/lakehouse layers (using Snowflake, ClickHouse, Azure Synapse, or Redshift), establishing optimal partitioning, indexing, and Slowly Changing Dimension (SCD Type 2) patterns.
• Data Quality & Testing Integration: Establish rigorous data quality checks and validation frameworks utilizing tools like dbt (data build tool), Soda, or customized PySpark testing suites.
• Collaboration & Design: Work closely with product owners, business analysts, and systems architects to define data requirements, analyze technical constraints, design Source-to-Target Mappings (STTM), and make critical architectural decisions.
• Code Quality & DevOps: Maintain a clean, modular code repository. Lead code reviews, enforce engineering standards, and configure robust CI/CD pipelines (Azure DevOps, GitLab CI, or GitHub Actions) with Docker containers.
• Technical Documentation: Deliver comprehensive, clear technical specs, metadata lineage documentation, architectural diagrams, and data dictionaries.

Qualifications

• 5+ years of hands-on experience in data engineering, data warehousing, database design, and end-to-end data integration.
• Advanced knowledge of Cloud Integration tools such as Azure Data Factory (ADF), AWS Glue, or GCP Dataflow.
• Proficiency in workflow orchestrators like Apache Airflow and exposure to CDC (Change Data Capture) or real-time streaming tools (e.g., Kafka, Debezium).
• Strong production-level coding skills in SQL (advanced optimization/stored procedures), Python, and PySpark / Apache Spark.
• Experience working with high-performance databases and cloud-native systems (e.g., Snowflake, ClickHouse, PostgreSQL, MS SQL Server, or Azure Synapse).
• Master-level understanding of data modeling practices (OLAP, OLTP, Star/Snowflake schemas, Delta Lake/Lakehouse patterns, and Data staging processes).
• Hands-on experience with version control (Git) and building automated deployment pipelines (CI/CD) for data products.
• Proven ability to articulate complex technical ideas clearly to both business stakeholders and developers. Fluency in English (Upper-Intermediate level or higher).

Nice to have

• Deep knowledge of dbt (data build tool) and schema validation practices.
• Experience using Docker or Kubernetes to package and deploy data applications.
• Experience building lightweight, serverless ingestion services (e.g., using AWS Lambda / Azure Functions and RESTful APIs).
