UI / Front-End Developer

We 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.

As 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.

Design 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.

Required Skills

• 5+ years of experience in front-end development.
• Advanced CSS skills: responsive, flexbox, grid, animations, cross-browser compatibility.
• Solid experience with vanilla JavaScript and jQuery (reading and modifying existing code).
• Good command of React: functional components, state management, lifecycle.
• Experience with Figma and translating designs into code.
• Comfortable in a startup environment, with legacy code and evolving priorities.
• Good communication skills in French and/or English.

Nice to Have

• Experience with Storybook or equivalent.
• Familiarity with design systems and atomic design methodology.
• Knowledge of CSS-in-JS solutions (styled-components, emotion).
• Use of AI tools in the development workflow.
• Bilingual French/English.
• Ability to present your design work to multiple stakeholders.

• Competitive compensation based on profile and experience.
• 50% coverage of group health insurance premiums.
• Health and wellness support: gym allowance, fitness classes, team sports, and $900/year in telecommunications allowance.
• A 100% remote position in Canada, with only 1 day/month required at our Brossard office.
• The opportunity to directly contribute to the growth of an AI-driven company in a large and underserved market.
• Close collaboration with our leadership team in a culture built on fitness, innovation, and speed.

We are looking for someone who loves clean code as much as the interface it produces, and who wants to leave a lasting mark on a fast-growing product.
