Lead Data Engineer

What You'll Do

Drive Data Architecture: Own the data architecture and modeling strategy for AI projects. Define how data is stored, organized, and accessed. Select technologies, design schemas/formats, and ensure systems support scalable AI and analytics workloads.
Build Scalable Data Pipelines: Lead development of robust ETL/ELT workflows and data models. Build pipelines that move large datasets with high reliability and low latency to support training and inference for AI and generative AI systems.
Ensure Data Quality & Governance: Oversee data governance and compliance with internal standards and regulations. Implement data anonymization, quality checks, lineage, and controls for handling sensitive information.
Provide Technical Leadership: Offer hands?on leadership across data engineering projects. Conduct code reviews, enforce best practices, and promote clean, well?tested code. Introduce improvements in development processes and tooling.
Cross?Functional Collaboration: Work closely with engineers, scientists, and product stakeholders. Scope work, manage data deliverables in agile sprints, and ensure timely delivery of data components aligned with project milestones.

What You'll Bring

Extensive Data Engineering Experience: 812+ years in data engineering or backend engineering, including senior/lead roles. Experience designing end?to?end data systems, solving scale/performance challenges, integrating diverse sources, and operating pipelines in production.
Big Data & Cloud Expertise: Strong skills in Python and/or Java/Scala. Deep experience with Spark, Hadoop, Hive/Impala, and Airflow. Hands?on work with AWS, Azure, or GCP using cloud?native processing and storage services (e.g., S3, Glue, EMR, Data Factory). Ability to design scalable, cost?efficient workloads for experimental and variable R&D environments.
AI/ML Data Lifecycle Knowledge: Understanding of data needs for machine learningdataset preparation, feature/label management, and supporting real?time or batch training pipelines. Experience with feature stores or streaming data is useful.
Leadership & Mentorship: Ability to translate ambiguous goals into clear plans, guide engineers, and lead technical execution.
Problem?Solving Mindset: Approach issues systematically, using analysis and data to select scalable, maintainable solutions.

Required Skills

Education & Background: Bachelor's degree in Computer Science, Engineering, or related field. 8-12+ years of proven experience architecting and operating production?grade data systems, especially those supporting analytics or ML workloads.
Pipeline Development: Expert in ETL/ELT design and implementation, working with diverse data sources, transformations, and targets. Strong experience scheduling and orchestrating pipelines using Airflow or similar tools.
Programming & Databases: Advanced Python and/or Scala/Java skills and strong software engineering fundamentals (version control, CI, code reviews). Excellent SQL abilities, including performance tuning on large datasets.
Big Data Technologies: Hands?on Spark experience (RDDs/DataFrames, optimization). Familiar with Hadoop components (HDFS, YARN), Hive/Impala, and streaming systems like Kafka or Kinesis.
Cloud Infrastructure: Experience deploying data systems on AWS/Azure/GCP. Familiar with cloud data lakes, warehouses (Redshift, BigQuery, Snowflake), and cloud?based processing engines (EMR, Dataproc, Glue, Synapse). Comfortable with Linux and shell scripting.
Data Governance & Security: Knowledge of data privacy regulations, PII handling, access controls, encryption/masking, and data quality validation. Experience with metadata management or data cataloging tools is a plus.
Collaboration & Agile Delivery: Strong communication skills and experience working with cross?functional teams. Ability to document designs clearly and deliver iteratively using agile practices.

Preferred Skills

Advanced Cloud & Data Platform Expertise: Experience with AWS data engineering services, Databricks, and Lakehouse/Delta Lake architectures (including bronze/silver/gold layers).
Modern Data Stack: Familiarity with dbt, Great Expectations, containerization (Docker/Kubernetes), and monitoring tools like Grafana or cloud?native monitoring.
DevOps & CI/CD for Data: Experience implementing CI/CD pipelines for data workflows and using IaC tools like Terraform or CloudFormation. Knowledge of data versioning (e.g., Delta Lake time?travel) and supporting continuous delivery for ML systems.
Continuous Learning: Motivation to explore emerging technologies, especially in AI and generative AI data workflows.
