AWS Lakehouse Data Engineer

Guidehouse is seeking an AWS Lakehouse Data Engineer to design, implement, and operate a cloud-native data platform supporting AI/ML, analytics, reporting, and data visualization. The role focuses on building AWS-native lakehouse architectures, scalable batch and streaming pipelines, governance and metadata services, Infrastructure as Code, CI/CD, observability, and cross-team technical collaboration.

Responsibilities:

• Design and implement batch and streaming ingestion from APIs, relational databases, file drops, event streams, and external partners
• Implement, test, and optimize ETL/ELT pipelines using Python and PySpark to produce curated, analytics-ready datasets for reporting, visualization, and machine learning
• Implement incremental processing, change data capture (CDC), data contracts, schema validation, and reusable transformation frameworks
• Improve pipeline reliability through automated testing, orchestration, monitoring, retry handling, and operational runbooks
• Design and implement a Delta Lakehouse-style data platform using AWS-native services to provide Databricks-like capabilities for data engineering, analysis, and data visualization
• Build and manage a scalable lakehouse on Amazon S3 using Apache Iceberg and open columnar formats such as Apache Parquet
• Implement SQL-like table reliability for data stored in Amazon S3, including ACID transactions, schema evolution, partition evolution, snapshot isolation, time travel, and rollback capabilities using Apache Iceberg
• Enable fast, interactive querying of lakehouse data using AWS-native query and compute services such as Amazon Athena, Amazon EMR, AWS Glue, and Amazon Redshift where appropriate
• Optimize performance and cost through partitioning, compaction, file sizing, statistics, caching, lifecycle policies, and efficient separation of compute and storage
• Establish standardized development, test, and production environments with consistent configuration and controlled promotion across stages
• Implement data governance and fine-grained access control using AWS-native services, including AWS Lake Formation, AWS Glue Data Catalog, AWS Identity and Access Management (IAM), AWS Key Management Service (KMS), and related security services
• Implement a managed metadata repository for dataset cataloging, ownership, business definitions, tagging, classification, and discoverability
• Enable end-to-end lineage from source through transformation and consumption to support auditability, impact analysis, and regulatory requirements
• Apply policy-based access, least-privilege permissions, row-, column-, and cell-level controls where required, data classification, retention, encryption, and secure data handling
• Build operational data quality checks for freshness, completeness, uniqueness, validity, consistency, and anomaly detection, and publish measurable SLAs/SLOs
• Implement automated AWS provisioning using Infrastructure as Code (IaC) to create consistent environments and secure-by-default baselines
• Build and enhance CI/CD for data pipelines and lakehouse components, including automated tests, security checks, validation gates, packaging, deployment, promotion, and rollback strategies
• Implement observability with centralized metrics, logs, traces, alerts, dashboards, runbooks, and incident-response procedures
• Continuously evaluate platform performance, scalability, reliability, security, and cost, and implement measurable improvements
• Work closely with data, application, analytics, AI/ML, security, networking, and cloud platform teams to support mission needs and delivery timelines
• Maintain high-quality engineering documentation, including architecture diagrams, data models, SOPs, interface specifications, operational runbooks, and secure configuration baselines
• Present technical findings, trade-offs, risks, and recommendations clearly to technical and non-technical stakeholders

Requirements:

• Bachelor's degree in Engineering, Information Technology, Computer Science, Data Engineering, or a related field, or FOUR (4) years equivalent practical experience in leu of degree
• SIX (6) years of relevant experience
• Hands-on experience implementing AWS-native data lake or lakehouse architectures using Amazon S3 and services such as AWS Glue, Amazon Athena, Amazon EMR, AWS Lake Formation, and Amazon Redshift
• Strong experience developing production ETL/ELT pipelines using Python and PySpark, including data modeling, transformation, testing, performance tuning, and error handling
• Hands-on experience with Apache Iceberg, including ACID transactions, snapshots, schema and partition evolution, time travel, table maintenance, and query optimization
• Advanced SQL skills and experience supporting analytical queries, semantic layers, reporting tools, and data visualization workloads
• Experience implementing metadata management and governance capabilities, including cataloging, lineage, ownership, classification, policy enforcement, and fine-grained access controls
• Experience with AWS security fundamentals, including IAM and least privilege, KMS encryption, secrets management, network security, logging, and secure SDLC practices
• Experience provisioning AWS resources using IaC and operating data platforms across multiple environments
• Experience building or operating CI/CD pipelines for data workflows, including testing, packaging, deployment automation, environment promotion, and rollback
• Ability to troubleshoot distributed data-processing workloads and optimize performance, reliability, and cost
• Ability to Obtain Public Trust
• Hands-on experience with Databricks, Delta Lake, or migrating Databricks workloads to AWS-native services and Apache Iceberg
• Experience with AWS Step Functions, Amazon Managed Workflows for Apache Airflow (MWAA), Amazon Kinesis, AWS Database Migration Service (DMS), AWS Lambda, Amazon MSK, or similar ingestion and orchestration services
• Experience with modern DevOps practices and tools such as Git, Terraform, AWS CloudFormation or AWS CDK, Jenkins, AWS CodePipeline, GitHub Actions, and Docker
• Experience integrating lakehouse data with business intelligence and visualization tools such as Amazon QuickSight, Tableau, or Power BI
• Experience using AI-assisted coding tools, such as GitHub Copilot, ChatGPT, Cursor, or Kiro, to accelerate implementation while maintaining code quality, testing, review, privacy, and security controls
• Knowledge graph and Graph RAG experience, including graph modeling, ontology and taxonomy alignment, entity resolution, relationship extraction, and hybrid retrieval that combines graph traversal with semantic or vector search
