- Four or more years of hands-on Apache Spark development experience in enterprise production environments.
- Strong proficiency in PySpark, Scala, or Spark SQL for distributed data processing.
- Deep understanding of Apache Spark architecture including RDDs, DataFrames, Datasets, Catalyst Optimizer, DAG execution, and Tungsten engine.
- Strong experience with distributed computing concepts including partitioning, shuffling, caching, broadcast joins, and fault tolerance.
- Advanced SQL skills with databases such as SQL Server, Oracle, PostgreSQL, Snowflake, or Teradata.
- Experience working with Hadoop ecosystem technologies including Hive, HDFS, YARN, and Parquet.
- Experience processing streaming data using Spark Structured Streaming, Apache Kafka, or Event Hubs.
- Hands-on experience with cloud platforms including Azure Databricks, AWS EMR, AWS Glue, Azure Synapse Analytics, or Google Dataproc.
- Experience integrating Spark applications with Delta Lake, Apache Iceberg, or Apache Hudi.
- Strong understanding of data warehousing concepts, dimensional modeling, and data lake architecture.
- Experience using Git, CI/CD pipelines, Azure DevOps, GitHub Actions, or Jenkins.
- Strong debugging, troubleshooting, and Spark performance tuning skills.
- Experience working in Agile Scrum development environments.
Nice To Haves
- Experience building enterprise Lakehouse architectures using Databricks or Delta Lake.
- Familiarity with Apache Airflow, Azure Data Factory, AWS Step Functions, or Control-M for workflow orchestration.
- Experience with machine learning workflows using Spark MLlib, MLflow, or feature engineering pipelines.
- Knowledge of Kubernetes, Docker, and containerized Spark deployments.
- Experience implementing Data Quality frameworks using Great Expectations or Deequ.
- Familiarity with Apache NiFi, Apache Flink, Trino, or Presto.
- Experience working with cloud object storage including Amazon S3, Azure Data Lake Storage (ADLS Gen2), or Google Cloud Storage.
- Knowledge of Infrastructure as Code using Terraform or ARM templates.
- Experience with enterprise monitoring tools including Prometheus, Grafana, Datadog, or OpenTelemetry.
- Cloud certifications in Azure, AWS, Databricks, or Apache Spark-related technologies are highly desirable.
Responsibilities
- Design, develop, and maintain high-performance distributed data processing applications using Apache Spark.
- Build scalable batch and real-time ETL/ELT pipelines processing large volumes of enterprise data.
- Develop Spark applications using PySpark, Scala, or Spark SQL for data transformation, aggregation, and analytics.
- Optimize Spark jobs for memory utilization, partitioning strategies, shuffle performance, and execution efficiency.
- Process structured, semi-structured, and streaming data from enterprise databases, APIs, Kafka, cloud storage, and data lakes.
- Develop reusable Spark libraries, data processing frameworks, and metadata-driven ingestion pipelines.
- Collaborate with cloud engineering teams to deploy Spark workloads on Databricks, EMR, Azure Synapse, or Kubernetes.
- Implement data quality validation, reconciliation, monitoring, and automated error handling across distributed pipelines.
- Integrate Spark applications with enterprise data warehouses, lakehouses, and reporting platforms.
- Participate in architecture reviews, code reviews, technical design discussions, and Agile development activities.
- Troubleshoot production issues involving distributed processing, cluster performance, resource utilization, and data quality.
- Support cloud migration initiatives by modernizing legacy ETL workloads into Spark-based architectures.
