About the role
About Kastle
Kastle is building the AI employee for banks. We work with some of America's financial institutions, 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 $2 billion in transactions and are backed by Insight Partners and Y Combinator. 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.
We just raised a $24M Series A and are growing fast!
About the Role
As a Forward Deployed Engineer at Kastle, you re-program entire companies.
You are not measured by technical complexity nor lines of code, but by ownership of business outcomes. Agency, judgment, and customer understanding are equally if not more valuable in this role as strong software engineering ability.
You will be driving a fundamental shift in how enterprises operate and how the largest banks in the world operate. You will own our most strategic customers to build and deploy automation and software that was previously impossible. These are not incremental improvements; you'll be replacing load-bearing workflows in production that previously consumed hundreds of thousands of human hours.
This role sits at the intersection of engineering, customer partnership, and operational excellence. You'll go deep into complex enterprise workflows, architect robust Agents using the Kastle Platform.
This role will be the best role for you if you are someone that is excited by business and solving real problems instead of only deriving value from writing code.
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 3 years of engineering experience, and 1 year of customer facing experience.
-
Proficiency in Python, Java, or similar; comfortable building APIs and backend systems.
