Candidates should have solid and recent experience building web applications using React.Vite: Vite is preferred but not mandatory. We can consider candidates with other modern React build tools if they have strong React experience.Web Development: The role is primarily web-focused, so candidates with strong web application development experience should be prioritized over candidates whose experience is primarily mobile-focused.Cloud Experience: Candidates must have hands-on cloud experience. The specific platform is flexible — AWS, Azure, or GCP are all acceptable.Mobile: The team also has a React Native application, so React Native experience would be a strong plus; however, the primary focus remains web development.Full-Stack: Candidates should have back-end/full-stack experience as well, but the priority should be on strong front-end engineers who can also contribute to the back end.Ideal Candidate ProfileThe ideal candidate would have:React + JavaScript + strong web development experience + cloud experience (AWS/Azure/GCP) + back-end/full-stack experience.React Native experience is a plus, particularly for candidates who have worked across both web and mobile applications.Based on these points, we can be flexible on Vite and the specific cloud platform, while keeping React, JavaScript, strong web experience, and cloud experience as the primary screening criteria.About the RoleWe are looking for a Senior Full Stack Developer with hands-on experience designing, building, and deploying responsive, end-to-end web applications.
