Junior Software Engineer - Scan Team (Connectivity & Ingestion)

Since day one, DataGalaxy has been guided by a simple conviction: data creates value when people align on it, adopt it, and turn it into business outcomes. Metadata is not the destination. It is the foundation that makes this possible. That’s why DataGalaxy built the value governance platform, a business-first approach that connects data and AI strategy to execution, IT teams to business teams, and metadata to business outcomes. The platform includes two core products: DataGalaxy Catalog and DataGalaxy Portfolio Center. Catalog is a metadata center to provide context, build trust, and ensure compliance. Portfolio Center is a product management tool to show value creation from initiatives and champion alignment from C-levels to business stakeholders. Founded in France and expanding rapidly across Europe and the United States, DataGalaxy is trusted by over 200 global enterprises, including Dior, Airbus, and SwissLife. The company is committed to driving data culture and literacy by helping organizations deliver metadata to the agents and value to the people.
Our values: Be intentional. Be clear. Be bold. Be humble.
