  • Backed by Peak XV, Bessemer, Kleiner Perkins, M12, Y Combinator, and more with $72M raised

  • Try talking to Vapi now!

Why We’re Hiring This Role:

  • We’re hiring a senior frontend engineer in San Francisco to raise the quality of the experiences customers use to build and operate voice AI agents.

  • This role will shape frontend experiences across call health and LLM observability, reporting, and analytics - a broad product surface with significant room for ownership.

  • You’ll shape data-heavy dashboards and call logs used by thousands of monthly active users, making complex, real-time workflows fast, accessible, and trustworthy.

What You’ll Do:

  • 30 Days: Ramp up on Vapi’s frontend stack and Agent Loop/Observe. Build context with engineering, product, and design, learn how dashboards and call logs connect to backend services, and ship a meaningful improvement.

  • 60 Days: Take end-to-end ownership of a core workflow in call health/LLM observability or reporting and analytics. Deliver production React, TypeScript, and Tailwind work with strong API integration, testing, and measurable improvements to performance, accessibility, or usability.

  • 90 Days: Become the primary frontend owner for your area. Establish reusable patterns in the design system and Storybook, improve how data-intensive and real-time interfaces scale, and help the team use agentic coding without compromising craft.

Who You Are:

  • 5+ years of professional software engineering experience with deep frontend expertise and a record of shipping customer-facing products.

  • Strong command of React, TypeScript, JavaScript, HTML, CSS, browser APIs, and integrating frontend applications with backend services and APIs.

  • Strong web performance and accessibility fundamentals, including tools such as Chrome DevTools and Lighthouse.

  • A test-driven approach spanning component, visual, and end-to-end testing, plus experience with Storybook and design systems.

  • Excellent product and UX judgment and strong collaboration with product and design in fast-moving environments.

  • Production experience with agentic coding tools and Tailwind CSS. Data-intensive dashboards, complex tables, pagination across millions of rows, or real-time interfaces are a plus.

How We Work:

  • Build something worthy of love

    • Craft matters. We aim to build products and experiences customers genuinely love, not just tolerate.

  • Commit and follow through

    • We finish what we start and build trust by being people others can count on.

    • Why not today?

      • We value urgency and momentum. The fastest path to customer value usually wins.

      • Seek raw input

        • We go directly to customers, data, and teammates instead of relying on summaries or assumptions.

        • It’s our problem

          • We operate as one team. We share credit, own mistakes together, and support each other when things get hard.

          • Be direct and kind

            • We give feedback clearly, respectfully, and without delay.

              • Why Vapi:

              • Generational impact: Build the human interface for every business

              • Ownership culture: Many of us are previous founders

              • Kind team: The founders, Jordan and Nikhil, are Canadians

              • Tier-1 Investors: YC, KP seed, Bessemer

              What We Offer:

              • Real stake: We offer a competitive salary and excellent equity ownership

              • Comprehensive health coverage: medical, dental, and vision plans

              • Team love: We love hanging out, and we do quarterly off-sites

              • Flexible time off: take what you need

              • More: catered meals, transportation, equipment, and a $10k annual L&D budget
