Data Engineer-II

JOB DESCRIPTION

• We need a senior contractor to design and build the data foundation for our B2B marketing in HubSpot.
• You will own the data model that connects the people, accounts, locations, and other records we market to.
• That model determines who our campaigns can target.
• You will also load data from our warehouse and other source systems into HubSpot and keep those syncs running and accurate.
• You will work closely with the Campaign Architect, whose Iterable-to-HubSpot migration depends on having the right properties, events, and associations in place.

Key Responsibilities

• Own the design of the HubSpot data model, including objects, custom objects, associations, and association labels for many-to-many relationships.
• Make and document the design decisions.
• Agree on source-of-truth tables, definitions, and refresh schedules with data engineering and analytics.
• Build and maintain syncs from the warehouse into HubSpot using Hightouch or native integrations.
• Map source fields to HubSpot properties, and define keys, deduplication rules, and update logic for each sync.
• Monitor sync health, with alerts for failures, volume changes, and schema changes.
• Fix issues quickly.
• Own data quality end to end, covering deduplication, standardization, validation, enrichment, and automated cleanup.
• Plan and run the move of Iterable user attributes, events, and subscription status into HubSpot.
• Set data governance standards, including access controls, consent fields, retention rules, and PII handling.
• Document the model, field mappings, and runbooks, and keep them current.

Required Skills

• 5+ years in data engineering, analytics engineering, marketing operations, or revenue operations, including 2+ years working hands-on with HubSpot data.
• Has designed a HubSpot data model with custom objects and associations and knows the platform limits that affect design.
• Advanced SQL, including profiling, transforming, and validating data in a warehouse such as Snowflake.
• Hands-on experience with reverse ETL (Hightouch, Census) and ETL/ELT tools (Fivetran, dbt, Airflow).
• Working knowledge of REST APIs and webhooks, including the HubSpot CRM and Associations APIs.
• Has led a large data migration that preserved relationships between records.
• Clear documentation habits and the ability to explain data concepts to marketers.
