About The Role

The Data Engineer will design, build, and operate scalable data pipelines and curated datasets that power analytics products, reporting, and advanced modeling. Working closely with the Lead and cross-functional partners (Product, Data Science, and Platform teams), this role focuses on reliability, performance, data quality, and governance across batch and (where applicable) streaming workloads.

Key Responsibilities

• Build and maintain robust ETL/ELT pipelines for ingestion, transformation, and aggregation of large-scale datasets on Hadoop and enterprise data platforms.
• Develop high-performance data processing jobs using PySpark/Spark, Python, and SQL (including engines such as Impala where applicable).
• Partner with Product and Analytics stakeholders to translate requirements into reusable, governed data models (facts/dimensions, curated layers, and semantic-ready datasets).
• Implement and automate data quality checks, reconciliation, lineage documentation, and monitoring to ensure trust in downstream analytics and AI use cases.
• Optimize pipeline performance and cost through partitioning, file formats, compute tuning, and efficient query patterns.
• Optimize pipeline performance and cost through partitioning strategies, columnar file formats (Parquet, ORC, Delta), compute tuning, caching, and efficient query patterns.
• Contribute to CI/CD for data workflows (testing, code reviews, deployment automation), promoting engineering best practices and maintainable codebases.
• Support data governance, privacy, and security requirements (PII handling, access controls, auditability) in collaboration with platform and risk partners.
• Collaborate with data scientists to publish analysis-ready and ML-ready datasets, including feature generation and repeatable data preparation processes.
• Troubleshoot production issues, participate in on-call/operational rotations, and drive root-cause fixes to improve reliability.
• Communicate data platform capabilities, limitations, and trade-offs clearly to technical and non-technical stakeholders.
• Strong problem-solving skills with ability to debug complex distributed data issues independently.
• Clear written and verbal communication with both technical engineers and non-technical business stakeholders.

All About You

• Strong hands-on experience in data engineering building production-grade pipelines on big data platforms (Hadoop ecosystem and/or cloud data platforms).
• Strong hands-on experience in data engineering building production-grade pipelines on big data platforms (Hadoop ecosystem: HDFS, Hive, Impala, YARN, Oozie).
• Proficiency in PySpark and Python and strong SQL skills across distributed and relational data stores.
• Experience with orchestration/integration tools such as Apache Airflow, Apache NiFi, Azure Data Factory, Pentaho, or Talend.
• Solid understanding of data modeling, incremental processing patterns (CDC, SCD Type 1/2), and building curated datasets for analytics and reporting
• Experience with cloud services (Azure/AWS/GCP) for data lakes, compute, and storage is preferred.
• Proficiency in columnar and open table formats: Parquet, ORC, Delta Lake, Apache Iceberg, or Apache Hudi.
• Strong knowledge of distributed computing patterns: partitioning, bucketing, broadcast joins, shuffle optimization.
• Working knowledge of DevOps/CI-CD practices: version control (Git), automated testing, release pipelines, and observability.
• Strong problem-solving skills with the ability to debug complex data issues and communicate clearly with technical and non-technical stakeholders.
• Bachelor’s degree in computer science, Engineering, or equivalent practical experience.
• 2.5-4 years of relevant experience in data engineering or big data analytics engineering (flexible based on depth of expertise).

GenAI / LLM Data Enablement (Preferred)

• Experience preparing curated, governed datasets (including semi-structured/unstructured) for AI/GenAI consumption with attention to privacy, quality, and reproducibility
