We are looking for strong React developers that have a keen eye for design and responsiveness, and a well-rounded experience across the stack. Bonus points for candidates that have backend experience in Java, Kotlin, Python, Go, or NodeJS, and a solid understanding of SQL and/or NoSQL databases.

Requirements

• Outstanding problem-solving, communication, and analytical abilities.
• Ability to bootstrap and architect a new React + Typescript application based on loosely defined designs and requirements. The candidate should possess well-founded perspectives on front-end project architecture and be able to articulate the advantages and disadvantages of various paradigms.
• Capable of selecting the appropriate React framework for specific tasks, drawing from a comprehensive understanding of the current React ecosystem, frameworks, and APIs/hooks.
• Knowledgeable in OAuth2 with a functional grasp of implicit and authorization code grant strategies, and able to implement these within a React client-side and/or SSR application.
• Familiar with responsive design principles—including media queries, container queries, CSS Grid, flexbox, masonry layouts—and capable of designing and implementing applications optimized for tablets, mobile devices, and desktop browsers, all while ensuring accessibility.
• Possess a substantial understanding of the intricacies related to cross-platform and cross-browser compatibility and deployment.
• Able to discern when to apply imperative versus declarative styles in React to integrate seamlessly with server-side REST APIs.
• Experience in developing design systems independently, without external dependencies. Familiarity with modern browser APIs such as MutationObserver, PopoverAPI, and WebRTC is essential.
• Expertise in the subtleties of semantic markup, including the appropriate use of diverse nodes and understanding their accessibility implications.
• Knowledgeable about the critical components of a React application to test, with experience using at least two recent testing frameworks such as Jest, Vitest, or Playwright.

Bonus points for:

• Design skills, including design thinking, wireframing, prototype development, leading meetings, and converting design concepts into executable implementations.
• Hands-on experience with AWS or other cloud-based platform development and integration.
• Practical proficiency in one or more application development frameworks/platforms, such as Node.js with Express/HAPI, Java with Spring/Spring Boot, or Python with Django/Flask/FastAPI.
• Working knowledge of configuring and/or utilizing a monorepo system such as pnpm or yarn.
• Experience with real-time data handling via WebSockets or other APIs.
