Senior Full Stack Engineer, AI Scheduling

Responsibilities

• Calendly’s AI Scheduling team is building AI-native solutions on top of our best-in-class scheduling product, creating new ways for customers to automate scheduling, reduce coordination work, and get more value from Calendly.
• We’re looking for a Senior Fullstack Engineer who is equally comfortable building polished React and TypeScript experiences and designing the backend APIs, services, data flows, and integrations that power them. You’ll report to the Engineering Manager on the AI Scheduling team and own meaningful customer outcomes.
• This is a high-ownership role in a fast-moving, 0-to-1 product environment. You’ll turn ambiguous problems into pragmatic solutions, lead projects independently from discovery through launch, and help grow the product’s user base by improving activation, reliability, and trust; fixing customer-facing issues; and adding valuable new capabilities. You’ll partner closely with our ML engineers, who own much of the model and agent behavior, and flex into prompts, evaluations, guardrails, or AI-service work as needed.
• Collaborating within your team to build new features that are targeted at our highest impact enterprise customers
• Meeting regularly with Product and Design to fine tune requirements
• Reviewing implementation plans and pull requests from your peers
• Significant experience with modern frontend development, including:
• Building complex, production-grade user interfaces with React and TypeScript or similar technologies.
• Working with state management, routing, forms, asynchronous data fetching, component libraries, and design systems.
• Designing and implementing REST or GraphQL APIs in Node.js, Ruby on Rails, or a similar web framework.
