The posting

Location: Remote Company Website: www.is.fun

About “is” “is” is a new kind of social content platform built around the concept of “Linked Micro-Content.” Instead of traditional posts or videos, users create short, expressive statements called “Isms” — small bursts of language and emotion that link together to form dynamic networks of thought, humor, news, and creativity. Each Ism can be styled, remixed, and transformed through AI-driven modes that affect visuals, motion, and tone. Our platform blends art, language, and machine intelligence into a living, collaborative content ecosystem.

We’re a small, ambitious team building the next frontier of creative expression — where AI, design, and human imagination meet.

Role Overview We’re looking for a highly skilled Front-End Web Developer specializing in React to help craft and evolve the is.fun user experience. You’ll build interfaces that are fast, dynamic, and visually expressive — enabling users to create and interact with “Isms” and AI-driven visual content in new ways. This role blends technical precision with creative flair, working closely with designers, back-end engineers, and AI teams to bring interactive features, motion, and seamless performance to life across browsers and devices.

Key Responsibilities · Develop, test, and optimize front-end components using React and modern JavaScript frameworks · Collaborate with designers to translate Figma prototypes and creative concepts into production-ready interfaces · Implement responsive layouts, animations, and dynamic transitions using React hooks, CSS modules, and modern styling libraries · Integrate RESTful and GraphQL APIs to connect data, content, and AI-driven services · Work with backend engineers to ensure reliable and secure front-end communication with the API layer · Contribute to the continuous improvement of performance, accessibility, and maintainability across the codebase · Participate in code reviews, sprint planning, and release cycles · Troubleshoot, debug, and resolve front-end issues in collaboration with QA engineers · Maintain consistency and scalability within our evolving design and component system

Qualifications · 5+ years of professional experience in front-end web development · Proficiency in React, TypeScript, and modern front-end build systems (Vite, Webpack, or similar) · Experience consuming RESTful or GraphQL APIs · Strong understanding of UI/UX principles and responsive design · Proficiency in HTML5, CSS3, and modular component architectures · Experience with Git, CI/CD workflows, and agile development practices · Strong debugging and performance optimization skills · Comfortable working in a fast-paced startup environment with shifting priorities

Nice to Have · Experience with Next.js or server-side rendering · Familiarity with WebGL, Three.js, or motion libraries like Framer Motion · Experience integrating AI or media processing workflows · Knowledge of automated testing (Playwright, Jest, Cypress) for front-end validation · Experience with cloud hosting environments such as Azure or AWS

Who You Are You’re a software front-end creative technologist who thrives at the intersection of design and engineering. You care deeply about interface quality, polish, and performance. You enjoy building components that feel alive — responsive, fast, and full of personality. You love collaborating with designers, experimenting with animation, and pushing what’s possible in the browser.

How to Apply 1. Visit www.is.fun and sign up for a free account. 2. In the top right, 'co-create' a new ism — a short statement or idea you’d feel proud sharing publicly. It can be about politics, entertainment, the news, or really anything or anyone - so long as it follows the linked micro-content format of subject-verb-predicate. 3. Attach an image or visual to your Ism to express it creatively. 4. Once published, copy the URL of your ism. 5. Submit your application here, including the link to your published ism in the provided field.

We review all applications that include a real, live Ism from the platform. Once you complete the steps above, you can follow up at the email address of [email protected].

  • How it was written, and how the review scored it

  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
