Senior Frontend Engineer

Own the Engineering. Make the Scheduling Magic happen.

Doodle is a B2B SaaS platform used by millions of professionals to coordinate meetings and collaboration. We are expanding from a scheduling product into a broader productivity and coordination platform, creating meaningful technical challenges ’re more than a Frontend engineer; you’re a feature owner, UX champion, and a continuous learner who thrives on shipping impactful user experiences. You’ll contribute to our design system and component architecture, playing a pivotal role in ensuring the frontend is accessible, blazing fast, and optimized for scale.

As a Senior Frontend Engineer, you’ll be instrumental in shaping our application’s future, focusing on architecture, performance, and developer experience.

• Architecture & Standards:
  Define the technical direction for our frontend stack. You’ll lead the implementation and governance of our Design System and Component Library, ensuring modularity, consistency, and reusability across teams.

• Performance Leadership:
  Own and enforce Core Web Vitals. You will optimize bundle sizes, build speeds, and asset delivery, while implementing advanced rendering techniques like React Server Components (RSC) within Next.js.

• Data & State Strategy:
  Architect solutions for efficient, localized state. You will champion Local State and React Context as the primary tools, strictly minimizing external state libraries. For highly complex atomic state flows, you will leverage lightweight solutions like Jotai. You will also master the Apollo Client cache to handle API data fetching.

• Developer Experience (DX):
  Act as the internal customer for the frontend platform. You’ll improve CI/CD pipeline efficiency, enhance local development tooling, and ensure high-quality documentation.

• Code Quality & Mentorship:
  Lead by example through rigorous code reviews. You’ll enforce Type Script best practices, mentoring mid-level engineers to foster a culture of technical excellence.

We are looking for an engineer who sees the frontend as a critical platform for product delivery.

• System-Level Thinking: 6+ years of frontend experience (4+ with React/Type Script). You have designed, owned, and shipped complex, multi-system features that define the technical direction for a product area.

• Performance Guru:
  Proven ability to diagnose and dramatically improve application performance under high load (browser runtime, network profiling).

• Foundational Mastery:
  Expert-level understanding of Vanilla JavaScript, HTML, CSS, and browser APIs. You can write robust code without a framework and understand how React works under the hood.

• Data Flow Mastery:
  Expert knowledge of Graph
  
  QL and Apollo Client. You prefer simple API contracts and know when to avoid unnecessary client-side complexity.

• Communication: A track record of collaborating effectively with Product and UX/UI to translate business goals into high-impact technical solutions.

• Technical Interview (Based on Case Study)

• Exec Interview
