About You

We are looking for a Frontend Engineer that loves building fully optimized, scalable products. We use NextJS and React in the frontend, along with different libraries such as Tailwind and Redux Saga, and interactivity weaved in (drag & drop, keyword events, etc). All in a modern web architecture based on real-time data subscriptions, serverless functions, asynchronous communication through websocket and queues, and scalable cloud services.

While you need to have strong knowledge of NextJS and Javascript in this role, we believe that you can learn the other libraries and technologies on the job if you have the right attitude and are eager to do so.

• Proficiency in NextJS and Javascript.
• Hacker mentality: this is a key startup position where you will be expected to execute fast and with top code and UI quality.
• Experience with React and its ecosystem (Redux, React Router, etc.).
• Familiarity with implementing complex user interactions, including event listeners, drag and drop, scroll control, and other interactive elements.
• Familiarity with modern build tools, package managers and version control systems (webpack, npm, git, etc).
• Polyglot developer: comfortable to constantly get your hands on new libraries, frameworks and technologies.
• Attention to detail: a keen sense of visual aesthetics and the ability to create polished, visually appealing frontend components.
• Team player: comfortable to share knowledge, help your team mates and exchange feedback.

Benefits

• Competitive salary aligned with your experience and impact.
• Flexible compensation plan (transport, restaurants, baby daycare…).
• Hybrid remote flexibility (work part of the week remotely, with periods of full remote).
• The latest tools and tech to do your job.
• High growth opportunity.
