interface.ai
San Francisco, CA Full Time
POSTED ON 12/21/2025
AVAILABLE BEFORE 1/20/2026
interface.ai is the industry's-leading specialized AI provider for banks and credit unions, serving over 100 financial institutions. The company's integrated AI platform offers a unified banking experience through voice, chat, and employee-assisting solutions, enhanced by cutting-edge proprietary Generative AI.

Our mission is clear: to transform the banking experience so every consumer enjoys hyper-personalized, secure, and seamless interactions, while improving operational efficiencies and driving revenue growth.

interface.ai offers pre-trained, domain-specific AI solutions that are easy to integrate, scale, and manage, both in-branch and online. Combining this with deep industry expertise, interface.ai is the AI solution for banks and credit unions that want to deliver exceptional experiences and stay at the forefront of AI innovation.

At interface.ai, we are at the forefront of a seismic shift in how banking experiences are imagined and delivered. As the first Principal Product Designer in our fast-growing startup, you will be leading the design revolution for a new era of banking defined by Agent AI. We envision the future of banking as a fully AI-powered, multi-modal experience—where traditional point-and-click (WIMP: Windows, Icons, Menus, Pointer) interfaces give way to seamless, conversational, and intuitive interactions. This is your opportunity to shape a digital companion that redefines financial well-being for customers (our 'BankGPT') and enhances workforce productivity for employees. You will not only own and evolve the product experience but also influence the cultural and creative DNA of our design team.

Responsibilities:

  • Lead the design process from concept to delivery, collaborating closely with product managers, engineers, and other cross-functional teams.
  • Conduct user research, gather insights, and translate findings into actionable design solutions.
  • Develop wireframes, prototypes, and high-fidelity designs for web and mobile applications, with a keen focus on usability and accessibility.
  • Design conversational interfaces for AI-driven interactions, leveraging natural language processing (NLP) and machine learning to deliver personalized and efficient user experiences.
  • Iterate on designs based on user feedback, usability testing, and data-driven insights to continuously improve product performance.
  • Establish and maintain design guidelines, patterns, and best practices to ensure consistency across all digital touchpoints.
  • Mentor and provide guidance to future members of the design team as the team grows, fostering a culture of creativity, collaboration, and continuous learning.
  • Drive the design vision for multi-modal interfaces that integrate voice, text, and visuals, eliminating legacy UI paradigms and enabling next-gen Agent AI experiences.
  • Collaborate with AI and engineering teams to redefine how customers interact with their bank and how employees work within the bank.

Requirements:

  • Bachelor's or master's degree in Design, Human-Computer Interaction, or a related field.
  • 10 years of experience in product design, with a strong portfolio showcasing expertise in conversational AI and banking products (experience in fintech is preferred).
  • Proficiency in design tools such as Sketch, Figma, Adobe Creative Suite, etc.
  • Deep understanding of user-centered design principles and methodologies, with a proven track record of delivering innovative and user-friendly digital experiences.
  • Experience designing conversational interfaces and familiarity with AI platforms (e.g., Dialogflow, IBM Watson, etc.).
  • Knowledge of banking industry trends and best practices is preferred.
  • Excellent communication and collaboration skills, with the ability to effectively articulate design decisions and rationale to stakeholders at all levels.
  • Strong problem-solving skills and a passion for tackling complex design challenges in a fast-paced, agile startup environment.
  • Skill in using prompt engineering techniques to enhance productivity, drive efficiency, and decision-making with generative AI tools.

Benefits:

  • Health: medical, dental, and vision insurance and wellbeing resources and programs
  • Time away: Public holidays and discretionary PTO package for flexible days off with manager approval
  • Financial: 401K, ESPP, Basic life and AD&D insurance, long-term and short-term disability
  • Family: Parental leave
  • Development: Access to internal professional development resources.
