About The Position

Senior Software Engineer (Backend/APIs) Experienced Software Engineers- bring your experience to work for you where people love to shop! Boscov's is a chain of full service department stores serving the total family needs of our customers. For over 100 years, Boscov's has been known for its great values and famous brands, and for offering a broad selection of quality merchandise in its stores and online. We are seeking a Senior Backend Engineer who is driven by ownership and impact. This role involves building and modernizing the systems that power a 100+ year old retail company — untangling legacy complexity, designing clean APIs, and raising the bar for engineering practices across the team. The ideal candidate is prepared to lead technical decisions, mentor others through the delivery of high-quality code, and contribute to the transformation of a stable enterprise into a faster, more modern organization.

Requirements

7+ years building software, with depth in backend/API development
C# / .NET expertise as a primary development platform
SQL proficiency, including writing, optimizing, and troubleshooting complex query plans
Well-developed engineering practices — including SOLID principles, design patterns, and testing strategies — with demonstrated, hands-on application rather than theoretical knowledge alone
Strong system design instincts, with the ability to identify trade-offs and ask the right questions during architectural discussions
Comfort with ambiguity — requirements are not always fully defined, and the ability to clarify, decompose, and drive forward is essential
Prior experience modernizing legacy systems, or a demonstrated enthusiasm for doing so

Nice To Haves

Experience with retail, inventory, or pricing systems
Exposure to mainframe integration (DB2, IBM zOS, etc.)
React, Node, or other frontend frameworks
Cloud platforms (Azure preferred) and containerization

Responsibilities

Design and build backend systems and APIs in C# / .NET with SQL (the position includes integration with DB2 on mainframe — direct mainframe coding is not required, though working knowledge is expected)
Modernize legacy systems — decompose, refactor, and replace where it makes sense
Own technical decisions across patterns, architecture, and trade-offs, bringing sound engineering judgment to all aspects of the role
Contribute to frontend work as needed (this is not a full-stack role, though comfort with HTML/CSS/JS is expected)
Write tests, champion CI/CD practices, and deliver reliable, production-quality code
Mentor team members through code reviews and pairing sessions, contributing to the elevation of engineering standards
