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

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