## Job description

## 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

You’re joining at an inflection point. Our usage has grown 40x in the last 6 months and our customers view us as their enterprise AI partner and want us to transform their operations across different lines of business. To help support that we are founding our product team and hiring for leaders to own product for one business vertical each. You will start by partnering closely with customers to build new features for our existing originations agents, guide deployments, support adoption and ensure they have the tools and insight they need to achieve meaningful outcomes. Overtime you will own the product strategy, product execution, integrations, and partnerships for the originations vertical to deliver an end-to-end AI originations platform.

## WHAT YOU'LL DO

- 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.

## WHAT WE'RE LOOKING FOR

- 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. We'll teach you originations faster than we can teach product instinct.

## HOW WE'LL MEASURE SUCCESS

Whether our origination agents beat the best human baseline on the same work — conversion, cycle time, touches per file, error rates. Whether customers are live, adopted, and expanding on both agents.

## HOW WE WORK

Small team, high bar. You'll have full ownership of a product line with top 10 lenders live on it from day one.

## Why join Kastle

- Opportunity to work with a world class team building a generational AI company that will redefine how every loan in America is made and managed
- Ability to move fast while your work impacting millions of customers. Add a new feature in a few days and ship it to top 10 lenders the next week.
- Competitive Compensation + Meaningful Equity at a high growth company
- High ownership and direct input on product direction, company culture, and how the FDE function scales

Other Perks and Benefits

- Covered Health and Wellness Memberships
- Robust medical, vision, & dental coverage
- 401(K) plan offering
- Paid Company Meals
- Company offsites to get to know the team

## About Kastle

## Core Business
- **Primary industry**: Consumer lending / Mortgage servicing technology (Fintech)
- **Target customers**: FDIC-insured banks, independent mortgage banks (IMBs), and large consumer lenders (B2B, Enterprise)
- **Mission or purpose statement**: To help traditional financial services companies better interface with their customers by automating high-volume phone calls with compliant AI agents.

## Products & Services
- **Avery (Servicing Agent)**: AI voice agent that handles borrower inquiries, payment collection, escrow questions, and loss mitigation. Integrates with ICE’s MSP system.
- **Collections Agent**: Automates payment reminders, engages delinquent borrowers early, and recovers past-due accounts.
- **Compliance Agent**: Monitors and scores every interaction against regulations (FDCPA, TILA, UDAAP, RESPA, TCPA) for 100% QA coverage.
- **Loan Officer Assistant**: Qualifies new loan inquiries and automates pre-qualification calls.
- **Sentinel (QA & Compliance Agent)**: Real-time monitoring and automated scorecards for borrower calls and servicing documentation.
- **Agent Builder**: Allows lenders to turn SOPs into AI agents using natural language, with no-code configuration.
- **Platform features**: Omnichannel support (voice, SMS, email, chat), simulation testing, transparent observability, and integration with existing contact center, payment processor, and LMS systems.

## Market Standing
- **Valuation**: Not disclosed (private startup)
- **Key Metric**: Total funding of $510,000 (Pre-seed round led by Y Combinator, June 2024)
- **Notable Investors/Partners**: Y Combinator (lead), ICE Mortgage Technology (integration partner)
- **Growth Signals**:
  - Headcount: 10 employees (+66.7% YoY)
  - Won LendingTree’s 2024 Innovation Challenge (Nov 2024)
  - Featured in a16z’s February 2025 fintech newsletter on voice AI
  - Integration with ICE’s MSP servicing system (April 2026)
  - Most deployed AI voice agents in the mortgage industry (per website)
  - Active job postings: 8 positions, with 300% yearly increase in listings

## Competitive Advantages
- **Purpose-built for compliance**: Pre-trained on key lending regulations (FDCPA, TILA, UDAAP, RESPA, TCPA) with a proprietary Compliance Engine.
- **Enterprise-grade integrations**: Direct connectivity with ICE’s MSP (the dominant mortgage servicing system) and other core systems.
- **Fast time to value**: Go-live in days with out-of-the-box agents that map to existing workflows.
- **Transparent AI**: All responses are fully explainable with built-in reasoning, enabling audit-ready operations.
- **Battle-tested track record**: Claims to have the most deployed AI voice agents in the mortgage industry, with proven metrics (70% lower cost per call, 40% lower handle time, 90%+ CSAT).

## Strategic Focus
- Deepening integrations with core mortgage systems (e.g., MSP) to reduce friction for large lenders.
- Scaling the AI agent workforce across the full lending lifecycle (origination, servicing, collections, compliance).
- Expanding from voice to true omnichannel (SMS, email, chat) and adding more pre-built agent types.
- Growing the enterprise customer base among FDIC-insured banks and IMBs.

## Why Work Here
- **Culture**: Early-stage YC startup with a small, high-agency team (10 people). Founders have strong product/engineering backgrounds (Redfin, Verkada). Emphasis on building mission-critical AI for a regulated industry.
- **Work policy**: Based in San Francisco (185 Channel Street). Likely in-office given the early stage and need for close collaboration.
- **Notable perks/engineering culture**: Opportunity to work on proprietary inference technology, compliance engine, and real-time AI systems. Roles span applied AI, forward deployment, and product management. High ownership and impact from day one.
- **Growth trajectory**: Rapid headcount growth (66% YoY), multiple open roles, and strong market traction suggest significant career growth potential.
