Hello, our name is Customertimes, but you can call us CT. We are a global digital engineering, product development, and technology consulting company. Headquartered in New York, we have a team of 1000+ experts working across 65+ countries.

You build and own the user-facing application: fast, usable by everyone, installable, and reliable, including offline scenarios.

How you'll make an impact:

• Develop and maintain the web client using React 19, TypeScript, and Vite;
• Implement Progressive Web App features: service workers, caching strategies, offline support, installability, and push notifications where relevant;
• Consume GraphQL APIs efficiently (e.g., Apollo Client or urql), with sound state and cache management;
• Build a reusable, WCAG-compliant component library and maintain design consistency;
• Optimize performance (bundle size, Core Web Vitals, rendering behavior);
• Write unit, component, and end-to-end tests; collaborate with QA on automation;
• Participate in code reviews and mentor less experienced engineers;
• Collaborate with the Solution Architect, backend engineers, and designers on technical approach.

What makes you a great fit:

• 5+ years of frontend development, with strong production experience in React and TypeScript;
• Hands-on experience with Vite and modern build tooling;
• Practical PWA experience (service workers, Workbox, manifest, offline strategies);
• Experience with GraphQL clients and client-side state management;
• Strong grasp of HTML/CSS, responsive design, and WCAG compliance;
• Experience with testing tools (Vitest/Jest, React Testing Library, Playwright/Cypress);
• Familiarity with Git workflows and CI pipelines.

You are a star if you have:

• Experience with React 19 features (Actions, use, Server Components concepts, the React Compiler);
• Data visualization experience;
• Frontend security and performance monitoring experience.
