Forward Deployed Engineer

Forward Deployed Engineer ABOUT KASTLE Kastle is building AI operating system for consumer lending, starting with mortgage. We work with some of America's largest mortgage lenders, helping them scale their contact center and compliance operations using AI-driven voice agents. Backed by Y Combinator, Commerce Ventures, and executives from Snapdocs, Google, and WePay, we are redefining lending with AI. ABOUT THE ROLE As a Forward Deployed Engineer, you’ll be the technical owner and project leader of our most important accounts. You’ll embed deeply with customers, translate business workflows into production grade AI agents, and manage the customer relationship and roadmap. RESPONSIBILITIES - Build, configure, and launch AI agents on Kastle’s platform to handle real borrower workflows - Write production-grade backend and full-stack code (Python, Java, TypeScript) to integrate with loan servicing systems, data sources, and telephony platforms. - Own the full agent development life cycle: prototype quickly, set up CI/CD, monitor live usage, iterate to targets, and document best practices to speed up future projects. - Scope ambiguous customer asks, prototype quickly, and iterate into stable deployments. - Act as the technical face of Kastle in key accounts, building trust through speed, empathy, and impact. - Feed customer learnings back into the core product, influencing roadmap and reusable tooling. WHAT WE’RE LOOKING FOR - At-least 1 year of engineering experience, and 1 year of customer facing experience. - Proficiency in Python, Java, or similar; comfortable building APIs and backend systems. - Bias toward outcomes: you care more about unblocking customers and delivering value than perfect abstractions. - Strong work ethic; very high attention to detail; can own a project end-to-end with limited or no guidance. - Customer-centric: confident working directly with business leaders as well as engineers.
