ThriftBooks is seeking a Senior Software Engineer with deep technical expertise, a natural curiosity, and a drive to see their work to deliver large meaningful change to our employees and customers. You will focus on developing new tools that re-think how we approach work in our fulfillment centers. Your work will intersect with new technologies in image processing, computer vision, LLMs, full-text search, and robotics. You are a software engineer first but are interested in learning and exploring in other areas as needed.

The ideal candidate will be well-versed in .NET/C#, SQL Server, and front-end frameworks like React. Beyond this core stack, you should also enjoy exploring new technologies, troubleshooting across platforms, and integrating diverse third-party solutions and APIs.

We’re looking for someone who combines technical depth with an eagerness to learn and innovate.

WHAT YOU WILL 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

WHAT YOU WILL NEED:

• 4+ years of hands-on experience in software engineering with a preferred focus on .NET/C#, and JavaScript
• Strong knowledge of relational databases—multi-table querying, grouping, optimization, and schema design
• Experience with front-end frameworks or libraries, such as Blazor, React, or JavaScript
• Familiarity with the “full stack” of development, understanding how back-end and front-end elements interact and function together
• Curiosity and readiness to explore new APIs, tools, technologies, and techniques.

Remote from AZ or WA. If you prefer in-person/hybrid, our offices are in the Seattle area.
