UI / Front-End Developer

About UsWe are FLiiP, a fast-growing SaaS startup transforming the management of fitness centers and multi-site operators. Our all-in-one platform helps gyms and studios centralize their operations, automate their communications, and maximize member retention. Backed by over CAD $4M in seed funding and participants in the Google for Startups Accelerator, we are experiencing sustained growth across North America. With an AI-first vision and a culture of continuous experimentation, we are a team that truly builds.

The RoleAs part of our platform modernization, we are recruiting a UI/Front-End Developer to build and implement our design system. This is a foundational role: you will be responsible for bridging the gap between design vision and technical implementation, working in close collaboration with our UI/UX designer. The profile we are looking for is a hybrid one: someone who starts from design (Figma, UI), masters CSS, and goes all the way to integration in React. Key ResponsibilitiesDesign System Implementation • Build and maintain a React component library using Storybook, based on our Figma designs. • Create reusable components following atomic design principles. • Establish design tokens, usage patterns, and associated documentation.

Integration & CSS • Deliver pixel-perfect, responsive, cross-browser compatible interfaces (web and React Native mobile). • Write clean and maintainable CSS, taking into account our existing codebase constraints.

Legacy Code Modernization • Progressively refactor HTML/CSS/jQuery/JavaScript code toward modern standards. • Maintain backward compatibility while improving code quality and consistency.

Collaboration & Tools • Work closely with our designer to validate the technical feasibility of designs. • Use AI tools (Copilot, Cursor, etc.) to accelerate repetitive tasks.
