Job Summary

We are looking for a visionary UI Architect with deep expertise in React to lead the design and development of user interfaces for our next-generation, cloud-native SaaS enterprise platform. You will define the frontend architecture, ensure best-in-class performance, and drive seamless user experiences across complex business workflows.

This is a critical role where you'll architect scalable solutions that power enterprise-grade features for thousands of global users.

Key Responsibilities

1. Frontend Architecture & Engineering

• Design and evolve a React-based architecture for a large-scale, multi-tenant SaaS platform deployed in the cloud.
• Create and enforce design principles for modular, reusable, and scalable UI components using tools like React, TypeScript, and Tailwind CSS/Emotion.
• Architect and guide implementation of component libraries, design systems, and theming strategies for consistent branding and UX across products.
• Optimize application performance, bundle sizes, and render strategies (e.g., lazy loading, code-splitting, SSR/CSR as needed).

2. Cloud-Native Focus

• Build for cloud-native environments, focusing on high availability, scalability, and multi-tenant architecture.
• Partner with DevOps and Platform teams to integrate CI/CD pipelines, cloud deployments (AWS/GCP/Azure), and monitoring tools.
• Embrace 12-Factor App principles and design UIs that work with distributed backend systems.

3. Leadership & Collaboration

• Lead and mentor a team of frontend engineers across multiple squads.
• Define and promote React development standards, best practices, and architecture blueprints across the organization.
• Work cross-functionally with Product, UX, Backend Engineering, and QA teams to ensure cohesive delivery and a unified customer experience.

4. Governance, Security & Quality

• Ensure accessibility (WCAG 2.1), internationalization (i18n), and performance benchmarks are consistently met.
• Establish frontend testing strategy using tools like Jest, React Testing Library, Cypress, etc.
• Partner with security teams to implement secure-by-design frontends aligned with SaaS compliance needs (e.g., OWASP, SSO, GDPR).

Required Qualifications

• Bachelor’s or Master’s in Computer Science, Software Engineering, or equivalent.
• 10+ years in frontend development with at least 4+ years of React-based architecture experience.
• Expertise in React, Hooks, Context API, TypeScript, and related frontend tools.
• Solid experience designing and maintaining cloud-native SaaS platforms.
• Hands-on with component libraries, monorepo tools (e.g., Nx, Turborepo), and state management (MobX, Zustand, Redux, or React Query).
• Familiar with REST, GraphQL, and real-time data streaming (e.g., WebSockets, SSE).
• Experience building for multi-tenant, micro-frontend architectures (preferred).

Nice to Have

• Familiarity with accessibility standards (WCAG 2.1) and implementation of ARIA roles and semantic HTML.
• Experience supporting localization and internationalization (i18n/l10n) at scale, including RTL layouts, regional formats, and dynamic translation frameworks.
• Knowledge of design tokens, Storybook, and headless UI libraries like Radix or Headless UI.
• Exposure to micro frontend architecture (e.g., Module Federation or Single-SPA).
• Experience with cloud-native DevOps tooling: Docker, Kubernetes, AWS/GCP deployments.
• Proficiency in analytics and observability tools like Sentry, Datadog, or LogRocket.

Soft Skills

• Strategic thinker with strong problem-solving and decision-making skills.
• Ability to work in fast-paced, agile environments with cross-functional teams.
• Clear communication and documentation skills for technical and non-technical stakeholders.

If you're a React expert passionate about shaping the future of cloud-native SaaS applications, and you thrive in a fast-paced, high-impact environment, we want to hear from you! Join us to architect experiences used by thousands of enterprise users around the world, and help define the next frontier of scalable, accessible, and beautiful enterprise software.
