Lead Data Engineer

• Serve as the technical authority for data architecture across the organization, making high-impact decisions on data lake design, streaming topologies, storage formats, partitioning strategies, and data modeling patterns
• Design, build, and maintain production-grade data pipelines - batch and real-time - from ingestion and transformation to serving and consumption
• Own the data platform: build and evolve the foundational infrastructure that engineering, ML/AI, and analytics teams depend on for reliable, governed, and performant data access
• Partner closely with ML/AI engineers to ensure training data, feature pipelines, and model serving data are accurate, fresh, and efficiently delivered - you are the upstream enabler for every model in production
• Collaborate with backend and full-stack engineers to design event-driven architectures, define data contracts, and ensure application data flows cleanly into the data platform
• Lead technical design reviews, architecture discussions, and RFC processes for data initiatives - driving alignment across engineering teams
• Identify and resolve systemic data issues: pipeline failures, data quality degradation, schema drift, latency in streaming systems, cost inefficiencies in storage and computing, and gaps in data observability
• Define and champion data engineering best practices: data modeling, schema evolution, data contracts, testing strategies, lineage tracking, cataloging, and governance
• Design and implement data quality frameworks - validation rules, anomaly detection, freshness checks, and alerting - so downstream consumers can trust the data without asking
• Collaborate closely with Engineering Managers, Product, Data Science, and Analytics to shape data roadmaps and ensure the platform evolves with business needs
• Mentor and grow engineers at all levels through code reviews, pairing, design feedback, and technical guidance on data engineering topics
• Contribute to hiring by conducting technical interviews and helping define what great looks like for data engineering at TFS
• Proactively communicate technical risks, tradeoffs, and recommendations to both engineering and non-technical stakeholders

• Bachelor's degree in Computer Science, Data Engineering, Information Systems, or related field, or equivalent practical experience
• 7+ years of software or data engineering experience, including 3-5 years focused specifically on data platform and pipeline engineering at scale, with a track record of operating at a principal or staff engineer level
• Deep expertise in designing and building data lake and Lakehouse architectures on AWS, including:

• S3 as the foundation for data lake storage, with strong opinions on partitioning, file formats (Parquet, Avro, ORC), and lifecycle management
• AWS Glue for ETL/ELT jobs, crawlers, and the Data Catalog
• Amazon Athena for serverless SQL analytics over the data lake
• Lake Formation for fine-grained access control, governance, and cross-account data sharing
• Amazon Redshift or Redshift Serverless for data warehousing and high-performance analytical queries
• Amazon EMR or EMR Serverless for large-scale Spark, Hive, or Presto workloads

• Production experience with real-time and streaming data architectures, including:

• Amazon Kinesis (Data Streams, Data Firehose) for real-time ingestion and delivery
• Amazon MSK (Managed Kafka) or self-managed Kafka for event streaming at scale
• EventBridge, SQS, or SNS for event-driven integration with application services
• Lambda for lightweight stream processing and event transformation
• Apache Flink (via Amazon Managed Service for Apache Flink) or Spark Structured Streaming for stateful stream processing

• Strong proficiency in Python and SQL - you write production-quality pipeline code, not just ad-hoc scripts, and you can optimize a complex query as fluently as you can design a DAG
• Experience with workflow orchestration tools: Step Functions, Apache Airflow (via Amazon MWAA), or similar - you know how to build reliable, observable, and recoverable pipeline DAGs
• Solid understanding of data modeling for both analytical and operational use cases: star schemas, slowly changing dimensions, wide tables, event sourcing, and CDC (change data capture) patterns
• Experience with data quality and governance tooling and practices: Great Expectations, Deequ, or custom validation frameworks - plus data cataloging, lineage tracking, and access control
• Strong understanding of Infrastructure as Code using AWS CDK, CloudFormation, or Terraform for data infrastructure
• Experience with observability and monitoring for data systems: pipeline health dashboards, data freshness tracking, SLA monitoring, and alerting on failures or anomalies (CloudWatch, Datadog, or similar)
• Strong understanding of security best practices for data: IAM policies, Lake Formation permissions, encryption at rest and in transit, data masking, and PII handling
• Deep experience debugging complex issues across data systems - pipeline failures, data skew, schema mismatches, streaming lag, and storage cost runaway
• Experience with testing strategies for data pipelines: data validation, schema contract testing, integration testing, and pipeline idempotency
• Strong written and verbal communication - you can write a clear RFC, lead a design review, and explain a data architecture tradeoff to a non-technical stakeholder

Added bonus if you have

• Master's degree in Computer Science, Data Engineering, or related field
• Experience in the financial services, banking, or insurance industry
• Experience with open table formats: Apache Iceberg, Delta Lake, or Apache Hudi for ACID transactions, time travel, and schema evolution on the data lake
• Experience with feature store design and implementation for ML/AI use cases (SageMaker Feature Store, Feast, or custom)
• Familiarity with dbt or similar transformation frameworks for analytics engineering and data modeling
• Experience with real-time analytics serving layers: Amazon OpenSearch, DynamoDB, or ElastiCache for low-latency data access
• Experience designing multi-account AWS data architectures with proper governance and guardrails (AWS Organizations, Control Tower, cross-account data sharing via Lake Formation)
• Hands-on experience with data mesh or data product patterns - decentralized ownership with centralized governance
• Experience with CDC (change data capture) tools: AWS DMS, Debezium, or similar for streaming database changes into the data lake
• Experience with cost optimization for data workloads: storage tiering, compute right-sizing, spot instances for Spark, and query optimization
• Experience with GenAI data pipelines: preparing training datasets, building RAG knowledge bases, embedding generation, and vector store population
• AWS certifications (Data Analytics Specialty, Solutions Architect, Database Specialty)
• Experience with CI/CD pipelines for data infrastructure and pipeline deployment (CodePipeline, GitHub Actions, or similar)
• Experience contributing to or maintaining open-source data engineering projects
• Experience defining engineering standards, writing ADRs, or leading org-wide technical initiatives
