Banking is being reimagined—and customers expect every interaction to be easy, personal, and instant .

We are building a universal banking assistant that millions of U.S. consumers can use to transact across all financial institutions and, over time, autonomously drive their financial goals . Powered by our proprietary BankGPT platform , this assistant is positioned to displace age-old legacy systems within financial institutions and own the end-to-end CX stack , unlocking a $200B chance and potentially replacing multiple publicly traded companies .

Ultimately, our mission is to drive financial well-being for millions of consumers.

With over two-thirds of Americans living paycheck to paycheck, 50% holding less than $500 in savings, and only 17% financially literate, we aim to put financial well-being on autopilot to help solve this problem.

About the Role

What You Will Do

- Design and build interactive demo experiences and sandbox environments that prospects can explore without sales friction—product-led, not pitch-led.
- Build PLG motion portals and self-serve experiences end-to-end across frontend, backend, and LLM integrations—shipping to real users that drive pipeline.
- Integrate GenAI / LLM pipelines—RAG, tool-calling, structured outputs, and evals—into customer-facing demos and proof-of-concepts.
- Work fluidly across multiple codebases, repos, and the full stack (frontend, backend, infra) to ship features from design to production.
- Be the product expert in sales engagements—answer technical and business questions, deliver custom demonstrations, articulate value, and provide technical competitive differentiation.




- Partner with Account Executives to tailor experiences to specific FI personas (VP Contact Center, VP Lending, VP Collections) with real data and live flows.
- Own technical writing for business-critical RFPs, RFIs, and security questionnaires, and maintain an accurate response library.
- Channel prospect and customer feedback back to Product, Marketing, and Leadership to shape the roadmap.
- Represent interface.ai at client events and tradeshows, and document client expectations and solutions sold for clean handovers to delivery.

What You Will Bring

- 4-10 years of total technical experience, with hands-on full-stack software engineering (frontend, backend, and APIs).
- Demonstrated ability to ship products end-to-end —you build things real users touch, with strong instincts for UX, latency, and the moment a user either “gets it” or bounces.
- Strong B2C product experience ; consumer-grade sensibility applied to enterprise demos and self-serve experiences.
- Comfort working across multiple codebases, repos, and stacks with high autonomy—TypeScript/React and Python preferred.
- High agency—you see a gap in the sales motion, build a tool for it, ship it, and tell the team. You don’t wait for tickets.
- Engineering or computer science background (mandatory).
- Ability to engage in value-driven conversations with CXO-level executives and explain technical concepts to non-technical audiences.
- Excellent written and verbal communication, including technical writing and formal presentation skills.
- Experience in a B2B SaaS startup environment; selling to or building for Financial Services is a plus.
- Skill with prompt engineering techniques to enhance productivity and decision-making with generative AI tools.
