Role

Who you are

We’re looking for someone who is strongest on the frontend, with solid backend experience and curiosity to go deeper where needed
7+ years of software engineering experience at a SaaS or technology company with a strong focus on UX engineering and design systems
Significant experience with modern frontend development, including:
Building complex, production-grade UIs with React and TypeScript
Comfort with state management, routing, forms, and asynchronous data fetching (e.g., Redux Toolkit, RTK Query, or similar patterns)
Strong grasp of CSS-in-JS or modern styling approaches, component libraries, and design systems
A focus on performance, accessibility, and responsive design
Hands-on backend experience, such as:
Implementing REST or GraphQL APIs in Node.js, Ruby on Rails, or a similar web framework
Working with relational databases (e.g., PostgreSQL) and understanding how schema and query design affect performance
Familiarity with service-oriented or microservice architectures, including how frontend and backend collaborate across service boundaries
Ability to work closely with designers, PMs, and other engineers; you explain tradeoffs clearly and can drive decisions to closure
Proven ability to deliver complex projects on time, including delegating to other engineers and cross-team collaboration
Experience using AI coding assistants (Copilot, Cursor, etc.) as productivity tools, with a clear understanding of generated code and the ability to defend implementation choices
Availability for participation in an on-call rotation, ensuring prompt and effective responses to business-critical alerts outside of regular working hours
Authorized to work lawfully in the United States of America as Calendly does not engage in immigration sponsorship at this time

What the job involves

Calendly’s Scheduling group is responsible for the core experiences that power how millions of people book, manage, and join meetings. We’re modernizing the Meetings Page and surrounding workflows, building richer UIs, and evolving our architecture toward a service-oriented, federated GraphQL world
We’re looking for a frontend-leaning Full Stack Engineer who loves crafting delightful, accessible, and performant user interfaces, and who is also comfortable working across backend APIs and services
You’ll report to an Engineering Manager in the Scheduling group and own end-to-end experiences that span from React components down through our API layer and services
You’ll help define and build the next generation of Calendly’s scheduling experience while keeping quality, reliability, and simplicity at the center of everything you ship
Own end-to-end features across the stack, with a strong emphasis on frontend: from collaborating on UX flows and designs, to building React/TypeScript UIs, to wiring those experiences into backend APIs and services
Collaborate closely with Product, Design, and other engineers to break down problems, refine requirements, and ship incremental value behind feature flags and experiments
Contribute to backend APIs and services: extend existing endpoints or services (e.g., in Node.js or Rails), design new data contracts, and ensure that backend changes are observable, well-tested, and resilient
Write automated tests across the stack (unit, integration, and UI tests) to protect critical user flows and keep regressions out of production
Review code and technical designs, giving and receiving feedback that raises the bar for clarity, maintainability, and performance
Mentor and coach other team members
In this role, you will spend the majority of your time coding and architecting systems, while simultaneously raising the bar for frontend development on the team

Our take

Calendly is a cloud-based scheduling service that is straightforward to use. It allows around 10 million customers per month to connect and make appointments based on their availability without having to send emails back and forth.

The platform offers four plans, allowing individuals, small companies, and large enterprises alike to make use of these services. Organic strategies have driven Calendly's growth. Its invites become links to Calendly itself, so people who like it can, and do, start to use it.

There are a handful of competing products on the market, including offerings from Doodle and Microsoft, but Calendly's customer-friendly design has won it attention and helped it to carve a space in the field. Impressive funding has contributed to the company's expansion, and its capitalised on the increasing popularity of home and hybrid working.
