Job Description — Lead Data Engineer

Role Overview

You will own the design, development, and optimization of large-scale data pipelines and platforms. This role needs someone who can combine strong engineering fundamentals with hands-on expertise in Python, distributed data processing (Spark), cloud architecture (AWS), and modern container/orchestration stacks (Docker, Kubernetes). You will guide the data engineering strategy, enforce best practices, and lead complex initiatives end-to-end.

Key Responsibilities

• Architect, build, and maintain scalable batch and streaming data pipelines using Spark (PySpark preferred).
• Develop robust, modular, production-grade Python services for ingestion, transformation, and ML-adjacent workflows.
• Optimize Spark jobs for performance, cost efficiency, and reliability in large datasets (TB-scale).
• Lead the design of data lake, lakehouse, or warehouse architecture (S3 + Glue + Athena, EMR, Redshift, or similar).
• Implement CI/CD pipelines for data services using tools like GitHub Actions / GitLab / Jenkins.
• Manage containerized workloads using Docker and deploy/operate them on Kubernetes (EKS preferred).
• Enforce data quality, lineage, governance, and schema management standards.
• Collaborate with ML engineers and data scientists to productionize models, ensuring scalable feature pipelines and deployment workflows.
• Perform code reviews, mentor team members, and uphold engineering best practices.
• Drive architectural decisions, capacity planning, and platform scalability.

Required Skills & Experience

• 6–10+ years in data engineering, software engineering, or distributed systems.
• Strong Python fundamentals: modular design, testing, async patterns, performance profiling.
• Advanced Spark/PySpark experience (RDDs, DataFrames, structured streaming, tuning, partitioning strategies).
• Strong AWS knowledge:
  • S3, EMR, Glue, Lambda, Step Functions
  • IAM policies & security
  • EKS experience is a strong plus
• Hands-on Docker and Kubernetes (K8s operators, manifests, Helm is a plus).
• Solid understanding of distributed systems concepts (fault tolerance, parallelization, memory management).
• Experience designing data models, ETL frameworks, and metadata management.
• Working knowledge of ML workflows (feature engineering pipelines, model deployment, feature stores).
• Experience with monitoring (Prometheus, Grafana), logging (ELK), and alerting systems.
• Strong problem-solving ability and the ability to cut through noise.

Nice to Have

• Experience with Delta Lake / Iceberg / Hudi.
• Terraform or CloudFormation for IaC.
• CI/CD for ML (SageMaker pipelines, MLflow, Kubeflow, or similar).
• Real-time streaming platforms (Kafka, Kinesis).
• Security and compliance experience (PII handling, encryption-at-rest/in-transit).

Soft Skills (the practical ones)

• Drives clarity, not chaos.
• Communicates architecture decisions clearly and defends them with logic, not buzzwords.
• Can mentor mid-level engineers without hand-holding.
• Can operate independently and handle ambiguity.
• Pushes back when something is poorly defined or technically unsound.
