• Day-to-day split. Approximately 80% dbt/transformation and data-modeling work and 20% collaboration with business stakeholders. This is not a ticket-taking role; someone who can receive a project, think critically, and run with it.

Responsibilities

• Design, implement, and support an analytical data infrastructure and working knowledge of Modern Data Warehouse concepts.
• Design, build, and maintain efficient and scalable data pipelines and ETL processes to process large volumes of structured and unstructured data.
• Optimize data storage and retrieval methods to ensure performance, scalability, and cost-efficiency.
• Manage AWS resources including EC2, S3, Glue, Lambda, API’s, IAM, CloudWatch, etc.
• Interface with other technology teams to extract, transform, and load data from a wide variety of data sources using SQL and AWS big data technologies
• Explore and learn the latest AWS technologies to provide new capabilities and increase efficiency
• Collaborate with Data Scientists and Business Intelligence Engineers (BIEs) to recognize and help adopt best practices in reporting and analysis
• Help continually improve ongoing reporting and analysis processes, automating or simplifying self-service support for customers
• Maintain internal reporting platforms/tools, including troubleshooting and development. Interact with internal users to establish and clarify requirements in order to develop report specifications.
• Work with Engineering partners to help shape and implement the development of BI infrastructure including Data Warehousing, reporting and analytics platforms.
• Contribute to the development of the BI tools, skills, culture, and impact.
• Write advanced SQL queries and Python code to develop solutions.
• Working Knowledge of Snowflake.
• Collaborate across teams to align AI initiatives with organizational goals and an understanding of AI concepts
• Knowledge of continuous integration/continuous delivery (CI/CD) pipelines and working on deployments when necessary.

Requirements

• Strong dbt development using SQL and Jinja.
• Strong SQL and Python fundamentals.
• Snowflake experience and an understanding of how modeled data supports reusable data products.
• Data modeling and semantic-model experience, not merely extraction and loading.
• Critical thinking, adaptability, project ownership, and comfort working directly with stakeholders.
• Bachelor's degree in Computer Science, Information Technology, or a related field.
• 3-5 years of experience in data engineering or a related role, with demonstrated success in delivering data solutions.
• AWS Glue, Lambda, S3, EC2, CloudWatch, Cloud Trail.
• Dbt, Snowflake, SQL, Python, Qlik.
• Proficient in SQL, with the ability to write complex queries, perform query optimization, and conduct performance tuning.
• Experience with NoSQL databases, such as MongoDB, Cassandra, or DynamoDB, and an understanding of their appropriate use cases.
• Strong programming skills in Python, Java, or Scala, with experience in data processing frameworks (e.g., Apache Spark, Hadoop).
• Experience with cloud platforms (AWS, Azure, GCP) and data services, such as AWS Redshift, Azure Synapse, or Google BigQuery.
• Knowledge of big data technologies, including Hadoop, Spark, Kafka, and HBase, with experience in distributed data processing.
• Familiarity with data orchestration tools, such as Apache Airflow for scheduling and managing data workflows.
• Experience with data versioning and testing tools, such as DVC (Data Version Control) and dbt (data build tool).
• Understanding of data security practices, including encryption, access controls, and data masking.
• 3-5 years of experience in data engineering or a related role, with demonstrated success in delivering data solutions.
• AWS Glue, Lambda, S3, EC2, CloudWatch, Cloud Trail.
• Dbt, Snowflake, SQL, Python, Qlik.
• AWS Glue and AWS data-lake experience. Azure is acceptable if the candidate understands data-flow and lake concepts.
• Finance, accounting, cash, P&L, or land-data experience shortens the learning curve.
• Iceberg and experience exposing or loading transformed data into Snowflake.
• Power BI awareness, although Rob is intentionally moving away from producing many custom reports.
• Interest in agentic data products and MCP servers.
