About The Position

Build the Infrastructure That helps Move the Mortgage Industry Forward. What if your code helped millions of Americans qualify for a home? At CreditXpert, that's not a marketing line, it's what we ship. For over 20 years, we've been quietly powering one of the most consequential decisions in a person's financial life: homeownership. And right now, we're in the middle of something big. We're expanding our API-first platform at the intersection of FinTech, advanced analytics, and AI and we need a sharp, motivated full-stack engineer to help us get there. You won't get lost in a sprawling org chart or buried in meetings. You'll be part of a small team of top performers who own their work end-to-end, ship things that matter, and push each other to grow. Here's what makes this role different: Design and ship production-grade REST APIs at the core of our platform strategy. Contribute to open-source MCP servers and CLI tooling with real external reach. Work in a purposeful, well-supported stack: C# .NET Core + React + AWS. Bring your curiosity about AI/LLM and agentic frameworks to a team actively building in that space (we use Claude Code daily). Do it all in service of a mission that genuinely improves people's financial lives. If you're a builder ready to grow fast, contribute meaningfully, and do work worth pointing to... keep reading. The Mid-Level Software Engineer (Full-Stack) will play a key role in building and evolving CreditXpert's product ecosystem. Operating with a high degree of autonomy within a supportive mentor/mentee relationship with their Technical Lead, this engineer will be instrumental in designing and delivering robust REST APIs, contributing to agentic tooling, and advancing workflow capabilities and user experience for CreditXpert's customers. At CreditXpert, you will be part of a small team of top performers who are passionate about our core values and excited about our mission. Job Mission: To build innovative, scalable, and reliable applications that enable mortgage lenders to leverage advanced analytics for risk management and decision support, helping make homeownership more accessible and affordable through cutting-edge FinTech solutions.
