We want to create the infrastructure that allows business owners to launch their company seamlessly. And also operate it hassle-free while keeping it compliant. Today, the infrastructure and services are at our hands to build these software layers, but we need a great engineer to help us deliver on this promise.

Knowledge: You’re familiar with current trends and best practices in frontend architecture, including performance, security, and usability. Experience with GraphQL is an added advantage.
Collaboration: You’re comfortable collaborating closely with designers, engineers, and product managers throughout the product and design life cycles to ensure the successful delivery of projects.
Flexibility: Comfortable working in EU or US time zones and flexible with adjusting working hours as needed to accommodate team meetings and collaboration across different time zones.
Quality Code: You write high-quality, well-tested code to meet the needs of our customers. Strong attention to detail and adherence to coding standards are essential.

💬 Potential Interview Questions

What are the benefits of using TypeScript in a React front-end codebase?
TypeScript improves code reliability with static typing, enhances IDE support, and reduces runtime errors through compile-time checks and better refactoring.
How do you optimize performance in a React + Next.js application?
Use SSR/SSG, lazy load components, memoize with React.memo, manage dependencies carefully, and use useCallback/useMemo to avoid unnecessary re-renders.
How do you handle GraphQL queries and mutations in React?
Use Apollo Client or similar, manage loading and error states, normalize data caching, and use fragments for reusable query components.
What is your approach to building reusable and maintainable UI components in React?
Follow atomic design principles, keep components pure and focused, use props and composition effectively, and maintain a component library.
How do you test React components with Playwright?
Write end-to-end tests simulating user behavior, assert DOM changes or API responses, and ensure consistent environments with proper setup and teardown.
How do you ensure high code quality and maintainability in a frontend codebase?
Enforce code standards with linters and formatters, write unit and integration tests, review code thoroughly, and document key components and logic.
What challenges can arise when integrating GraphQL APIs, and how do you handle them?
Challenges include schema evolution, over-fetching/n+1 issues, and error handling; solve with versioning, batching, and clear error boundaries.
How do you collaborate effectively with product managers and designers?
Communicate requirements early, clarify user flows, iterate on feedback, maintain design consistency, and track progress via shared tools.
What techniques do you use to ensure a responsive and accessible UI?
Use semantic HTML, ARIA attributes, media queries, keyboard navigation, and tools like Lighthouse or Axe for accessibility audits.
