About the Role

We’re looking for a strong Software Engineer with a frontend focus to build and scale high-performance scheduling and booking experiences. You’ll work across the stack — primarily on frontend systems like booking widgets and calendar views, while also contributing to APIs and backend integrations that power them.

This role requires strong execution, end-to-end ownership, and the ability to navigate ambiguity while delivering scalable, reliable systems.

Responsibilities:

1. Build and ship high-quality frontend features using Vue.js and Nuxt
2. Own projects end-to-end: requirements → design → implementation → testing → deployment → monitoring
3. Develop performant, responsive, and accessible UI components and booking flows
4. Optimize frontend performance (SSR, hydration, lazy loading, Core Web Vitals)
5. Design and integrate with backend APIs for scheduling, availability, and booking workflows
6. Contribute to backend services where needed (API design, data modeling, performance)
7. Break down complex problems into clear, actionable tasks and drive them to completion
8. Collaborate closely with Product, Design, and Backend teams to deliver intuitive user experiences
9. Proactively identify tech debt and improve system reliability

Requirements:

1. 3–6 years of software engineering experience (frontend-heavy)
2. Strong proficiency in Vue.js, Nuxt (2 or 3), and modern JavaScript/TypeScript
3. Solid understanding of browser rendering, performance optimization, and responsive design
4. Working knowledge of backend systems (APIs, databases, system design fundamentals)
5. Experience building scalable, maintainable systems across frontend and backend boundaries
6. Ability to independently drive features from idea to production

How You Work

1. Operate with ownership: take goals, define the approach, and execute independently
2. Communicate proactively on progress, risks, and trade-offs
3. Navigate ambiguity and make pragmatic decisions without waiting for perfect specs
4. Balance speed with long-term maintainability and scalability
5. Write clear design docs, PRs, and contribute to thoughtful code reviews

Team Impact

1. Contribute to improving frontend architecture, performance, and developer experience
2. Raise the bar on code quality, testing, and best practices
3. Help drive a culture of ownership, accountability, and continuous improvement

Why Join Us?

1. Build high-scale, high-impact systems used in real-world workflows
2. Own problems end-to-end across frontend and backend
3. Work in a fast-moving, high-ownership environment
4. Tackle complex product and engineering challenges with real user impact
