About the Project
Transforming the leisure and tourism photography experience: Powered by patented technology, our platform combines advanced association methods with an AI learning engine to enable real-time media streaming at scale, without compromising guest privacy.
The platform uses AI to recognize individuals within crowded and dynamic environments such as amusement parks and events, allowing guests to simply upload a selfie to match it with media captured in real time. The platform automatically associates all relevant photos and videos with a user and delivers them directly to their device.
The Role
We're seeking a highly motivated Senior Full-Stack Developer with deep frontend expertise to join our R&D team as our frontend Subject Matter Expert (SME). You'll work closely with cross-functional teams to deliver modern, user-centric solutions that drive our journey toward next-generation, market-leading technologies.
This is an opportunity to shape the user experience of platforms that serve millions of guests worldwide, creating intuitive and performant interfaces for photo and video redemption, viewing, and sharing experiences.
While this is a frontend-focused role, the candidate should be comfortable understanding backend services and contributing when needed, but will not be a primary backend owner.

Frontend Expertise: Advanced proficiency in React and/or Vue.js with deep understanding of modern frontend architecture. Own frontend technical decisions end-to-end, from design through production and iteration

State Management: Experience with Redux, Vuex, Zustand or similar state management solutions
Performance Optimization: Proven track record of building highly performant, scalable frontend applications
Programming Languages: Advanced proficiency in TypeScript and JavaScript
Backend Integration: Experience integrating with RESTful APIs and microservices
AWS Knowledge: Familiarity with AWS services (Lambda, API Gateway, S3, CloudFront)
Database Understanding: Working knowledge of SQL and NoSQL databases (DynamoDB, MongoDB, MySQL)
Modern Tooling: Experience with build tools, bundlers (Webpack, Vite)
Testing Practices: Experience with unit, integration, and E2E testing (e.g., Jest, Testing Library, Cypress, Playwright)
Scalability Mindset: Demonstrated ability to implement scalable, maintainable frontend solutions
Nice to Have
Additional Languages: Java for backend services
Frontend Architecture Leadership: Defining frontend architecture standards, patterns, and conventions across multiple teams or products
CSS Frameworks: Tailwind CSS, styled-components, or CSS-in-JS solutions

Design Systems: Experience building and maintaining component libraries
Progressive Web Apps: PWA development experience
WCAG / accessibility standards in production applications
