About Kastle
Kastle is building the AI employee for consumer lending. We work with some of America's largest banks and mortgage lenders, helping them scale their contact center and compliance operations using autonomous AI Agents that process payments, originate loans, and help customers get a world class experience during the biggest financial decisions of their lives. We've processed over $1 billion in transactions and are backed by Y Combinator and Commerce Ventures. If you are interested in building AI that is applied in the real world where precision, reliability, and performance matter and redefine access to credit across the world, apply below.
About the Role
As a Forward Deployed Engineer, you’ll be the technical owner of our most important agents. 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 2 years 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.
Nice to Have
Previous customer-facing engineering role (forward deployed, solutions engineer, etc.).
