Mortgage Cadence delivers enterprise-grade loan origination software that powers some of the most respected lenders in the mortgage industry. Our platform handles complex, high-volume workflows across the full origination lifecycle, and we are continually modernizing it to meet the demands of a dynamic market. Join a team where the code you write directly impacts how millions of borrowers finance their homes.

Position Overview

We are looking for a Mid/Senior .NET Software Developer to join the team behind Document Center, our mission-critical loan origination document generation service. Document Center sits at the heart of the lending workflow—responsible for producing, managing, and delivering the documents that move loans from application to close. You will work across the stack to deliver well-designed features, maintain the reliability our lenders depend on, and contribute to architectural conversations as we continue modernizing the service. You’ll operate within a small Agile team and collaborate closely with product, QA, and senior engineers to ship dependable software at enterprise scale.

Key Responsibilities

• Develop, test, and maintain features across the .NET-based platform, from APIs to user-facing interfaces.
• Write clean, well-tested C# code and contribute thoughtful peer code reviews.
• Build efficient SQL Server queries, stored procedures, and data models in support of feature work.
• Work with internal services and external third-party integrations as part of feature delivery.
• Diagnose and resolve defects across development and production environments.
• Partner with senior engineers on design and architecture; bring ideas and pushback when warranted.
• Contribute to documentation, automated testing, and continuous improvement of the engineering process.

Requirements

• 5+ years of professional software development experience on the Microsoft technology stack.
• Proficiency in C# and the .NET framework / .NET Core.
• Solid experience with ASP.NET for building web applications and services.
• 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.

Preferred Qualifications

• 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.
• Experience working with internal and external services and integrations.
• Exposure to Redis for caching and distributed data.
• Exposure to RabbitMQ (RMQ), Azure Service Bus (ASB) or similar messaging platforms.
• Experience developing and deploying workloads on Microsoft Azure.
• Experience contributing to large enterprise applications.

What You'll Bring

• Curiosity and a willingness to dig into unfamiliar parts of a large codebase.
• A self-starter attitude—you can take a story and run with it, asking the right questions along the way.
• Care for craft: readable code, sensible tests, and thoughtful design.
