We are seeking a hands‑on Data Engineer to take ownership of the day‑to‑day development and reliability of our data environment. You will help evolve an existing, relatively flat data structure into a more scalable and performant analytics warehouse while ensuring current pipelines and integrations remain reliable.

This role will focus primarily on data ingestion, SQL development, data modeling, normalization, and Snowflake‑based analytics solutions. You will work closely with the Director of Software and Data, gradually assuming ownership of the technical data responsibilities currently managed by that role.

The ideal candidate has a genuine background in data engineering, can work independently without extensive oversight, and understands how to structure data for reliable analytical use. Over time, the position may also contribute to predictive analytics and machine‑learning use cases supporting logistics and resource‑planning decisions.

• Take ownership of the day‑to‑day development and support of the company’s data environment.
• Build, enhance, and maintain data pipelines that ingest information from SQL Server, PostgreSQL, SaaS platforms, internal applications, APIs, and file‑based sources.
• Support data replication and ingestion using tools such as Hevo, Azure Data Factory, Azure Blob Storage, and Snowflake tasks and stages.
• Continue developing the company’s Snowflake‑based analytics warehouse and supporting analytical structures.
• Replace or improve existing flat data structures by designing more scalable, performant, and maintainable data models.
• Design data models that support increasingly complex analytical and operational business requirements.
• Write and optimize SQL queries, transformations, and data‑processing workflows.
• Perform data acquisition, cleaning, normalization, validation, and preparation for downstream analytics.
• Monitor existing pipelines and troubleshoot data ingestion, transformation, or reliability issues when they arise.
• Integrate new data sources as business and reporting requirements evolve.
• Ensure data quality, consistency, integrity, and availability across the data environment.
• Prepare reliable datasets and analytical models for business users working within Sigma.
• Document data sources, pipelines, transformations, models, and technical processes.
• Collaborate with software engineering and business teams on products that require analytical data solutions.
• Contribute to future predictive analytics and machine‑learning initiatives as the data platform matures.
• Provide after‑hours support when necessary to address critical data‑pipeline issues.

• At least 4 years of hands‑on experience in data engineering, analytics engineering, or a closely related data‑focused role.
• Strong SQL skills, including the ability to develop, troubleshoot, and optimize complex queries and data transformations.
• Strong understanding of data architecture, data modeling, normalization, and analytical data structures.
• Hands‑on experience building and maintaining ETL/ELT pipelines.
• Experience working with Snowflake or a comparable cloud data warehouse.
• Experience integrating data from relational databases, particularly SQL Server and/or PostgreSQL.
• Experience with data‑replication or integration tools such as Hevo, Fivetran, Stitch, or similar platforms.
• Experience working with Azure Data Factory or a comparable cloud‑based data…
