What You’ll Do

• Design and develop software tools that drive efficiency, automation, and scalability within our fulfillment centers
• Create solutions using .NET/C# and SQL Server that enhance operational performance across the environment
• Collaborate with fulfillment center stakeholders to gather requirements, identify pain points, and deliver impactful, user-centered tools
• Take ownership of projects from concept to production—integrating, troubleshooting, and delivering solutions end-to-end to ensure smooth, reliable deployment and performance
