About the role

Kastle is building the AI employee for consumer lending. The Senior Product Manager will own the originations product line end-to-end, work with AI engineers on autonomy and eval criteria, manage deployments and customer adoption, and drive product strategy for the originations vertical.

Responsibilities

  • Own the originations product line end to end — roadmap, prioritization, and delivery for both of our AI origination agents
  • Work directly with AI engineers on failure modes, eval criteria, and the judgment calls of autonomy — when the agent acts, when it asks, when it escalates
  • Own deployments of your product: project-manage post-sale implementations, drive customer adoption, and be the reason the exec sponsor's rollout worked
  • Close the loop from field reality back into the roadmap
  • Own originations product marketing. Positioning, demo narrative, case studies from live deployments.

Qualifications

  • 4+ years in product management, or equivalent ownership as a founder, engagement manager, or operator who shipped real product
  • You've built with LLMs hands-on — you can write and critique prompts, reason about evals, and engage engineers on how, not just what
  • A metrics habit: every claim you make about your product traces to instrumentation you made sure existed
  • You've owned customer-facing outcomes, not just internal roadmaps — deployments, implementations, or embedded work with enterprise customers
  • You write persuasively enough that an EVP forwards it internally
  • Comfort in fast-moving, ambiguous environments where you shape the solution as much as you build it
  • Experience in mortgage, lending, or another regulated industry is a plus, not a requirement.

About Kastle

AI agents for mortgage servicing

Kastle is an AI voice agent for mortgage servicing. We help servicers collect payments, verify new borrowers, and qualify new loan inquiries over the phone. Rishi and Nitish met at UIUC where they graduated with degrees in systems engineering and computer science. Rishi was the founding Product Manager for Redfin’s Mortgage Marketplace at 22 and grew the business from $3M to $6M in revenue in 9 months. Nitish patented Verkada’s motion search system and was the youngest tech lead at the company at 23. While building Redfin's Mortgage Marketplace Rishi realized traditional lenders didn't have the infrastructure to service online inquiries and were losing customers. Nitish and Rishi are building Kastle to help traditional financial services companies better interface with their customers.
