Senior Frontend Engineer

We’re looking for a Senior Frontend Developer to take a lead role in building and evolving our Shared Design Library - a core set of reusable React components, design tokens, and UX patterns that power our applications. This is a role for someone who is highly technical, self-driven, and passionate about delivering clean, scalable code, but who also excels at communication and collaboration.

You’ll work closely with designers, product managers, and other engineers to define standards, implement best practices, and ensure consistency across our products.

At our company, we're on a mission to change the world by revolutionizing the digital landscape. Our cutting-edge web and mobile applications are designed to enhance user experience and improve customer engagement, with quality and security at the core of everything we do.

We’re a fast-growing, purpose-driven scale‑up where you’ll make an impact, feel empowered, and thrive in a diverse, innovative environment.

• Lead the implementation of a Shared Design Library with reusable React components, design tokens (colors, typography, spacing), and UX patterns used across applications
• Define the foundations of the library: naming conventions, versioning strategy, theming, accessibility standards (WCAG), and contribution guidelines
• Set up and maintain component documentation (Storybook, MDX) with usage guidelines and live examples
• Establish governance for proposing, reviewing, deprecating, and evolving components in partnership with UI/UX Designers and QA
• Define and implement a testing framework/strategy: component unit tests, visual regression, accessibility checks, and integration tests
• Collaborate with Product Designers to translate guidelines into tokenized, testable components, ensuring consistency across apps
• Integrate the library into CI/CD pipelines with automated builds, tests, visual regression, and versioned releases
• Write clean, maintainable, scalable code in Type Script and React, building responsive, reliable, and secure web applications
• Own feature development from idea to deployment, aligning closely with product, design, backend, QA, and BA teams
• Review code, challenge assumptions, and help raise the technical bar across the team
• Mentor less experienced engineers and support team growth through technical guidance
• Help shape frontend architecture and long‑term decisions (modularity, patterns, performance)

• 5+ years of professional experience in frontend development with expertise in Type Script, modern JavaScript, and the React ecosystem (hooks, context, modular design)
• Experience designing or contributing to a design system or shared component library (tokens, theming, accessibility, documentation)
• Solid understanding of HTML5, CSS3, responsive design, web security, performance, and accessibility best practices
• Experience designing or contributing to scalable frontend architectures
• Comfortable in a fast‑paced, iterative, CI/CD environment with agile processes and rapid feedback loops
• Proficient with Git, npm/yarn, and modern frontend tooling
• Strong communication skills, valuing direct feedback and open dialogue
• Supportive team player who actively shares knowledge and mentors colleagues
• Able to navigate ambiguity and adapt to changing priorities, balancing multiple tasks and shifting business needs
