Role Description We are looking for a Mid/Senior .NET Software Developer to join the team behind Services Center, our non-interactive integration hub that connects the loan origination system to a wide ecosystem of third-party vendors and services. Services Center operates entirely in the background—it has no user-facing interface—and its core mission is reliable, accurate data exchange. - Design and maintain the integration layer that lenders and vendors depend on. - Work through vendor specifications, building robust data pipelines. - Ensure every handoff between systems is precise and traceable. - Operate within a small Agile team and collaborate closely with product, QA, and senior engineers to ship dependable software at enterprise scale. - Design, develop, test, and maintain integration features within the .NET-based Services Center, including service connectors, data transformation pipelines, and vendor-facing APIs. - Write clean, well-tested C# code and contribute thoughtful peer code reviews. - Build and maintain efficient SQL Server queries, stored procedures, and data models, with emphasis on the mapping and transformation schemas that underpin vendor integrations. - Implement and maintain integrations with third-party vendors by interpreting vendor specifications and ensuring accurate bidirectional data exchange. - Diagnose and resolve defects across various environments. - Partner with senior engineers on integration design and architecture; contribute ideas on reliability, retry patterns, error handling, and observability for non-interactive services. - Contribute to documentation (including integration specs and data mapping references), automated testing, and continuous improvement of the engineering process. Qualifications - 5+ years of professional software development experience on the Microsoft technology stack. - Proficiency in C# and the .NET framework / .NET Core. - Solid experience designing and consuming web APIs and working with external vendor specifications to implement reliable data exchange. - Working knowledge of SQL Server, including writing performant queries and stored procedures. - Demonstrated ability to work independently as a self-starter and drive tasks to completion. - Experience working in Agile team structures. - Strong problem-solving, communication, and collaboration skills. Requirements - Experience building or maintaining distributed, high-throughput systems where reliability and performance are non-negotiable. - Demonstrated experience with performance profiling, optimization, and tuning—whether at the application, query, or system level. - Hands-on experience implementing third-party vendor integrations, including interpreting API documentation, handling authentication schemes, and managing field-level data mapping. - Exposure to Redis for caching and distributed data. - Experience developing and deploying workloads on Microsoft Azure. - Experience contributing to large enterprise applications.
