About The Position

Join a data integration and orchestration team responsible for moving enterprise data from multiple source systems into modern destinations used for reporting, analytics, and business operations. The team works with APIs, SQL Server, SFTP, flat files, SharePoint, cloud storage, and destinations such as Azure Blob and Snowflake. This is a hands-on, fast-paced environment that values practical engineering, reliable data movement, and independent delivery. This contract-to-hire opportunity focuses on backend data integration rather than UI-heavy application development. The selected developer will build and enhance C#/.NET console applications, support existing ETL workflows, and help the team prepare for future Azure Data Factory work. The role is onsite four days per week in South Park, Charlotte, North Carolina, and is W2 only. The position may also provide future exposure to Python, Palantir Foundry, and AI-enabled data quality initiatives.

Requirements

At least 2 years of hands-on C#/.NET console application development experience.
Direct experience building C# console applications, not solely supporting applications built by others.

Experience with data integration workflows and large-volume data.
Understanding of API endpoints, requests, responses, pagination or limits, and data retrieval.
Experience with SSIS or another ETL/integration tool, such as Informatica.
Basic SQL knowledge.
Strong listening, communication, problem-solving, and ownership skills.
Comfort working onsite four days per week in South Park, Charlotte, NC.
