Senior Frontend Developer

Role Description

We're looking for a Senior Frontend Platform Engineer to join the Platform Services team responsible for the foundation that powers multiple React applications across the organization. This is not a feature-delivery role. Instead, you'll help design and evolve the frontend platform itself—building reusable infrastructure, improving architecture, establishing engineering standards, and solving complex cross-application challenges around:

• State management
• Authentication
• Performance
• Observability
• Resilience
• Developer experience

The ideal candidate enjoys working on platform engineering problems, understands frontend architecture at scale, and can confidently explain technical tradeoffs backed by real production experience.

Qualifications

• 5+ years of professional Frontend Engineering experience building large-scale React applications.
• Expert knowledge of React, TypeScript, JavaScript (ES6+), HTML5, and CSS3.
• Deep understanding of frontend architecture, component design, and application scalability.
• Strong experience designing complex state management solutions using Redux Toolkit, TanStack Query, or similar technologies.
• Experience building robust authentication and authorization flows, including JWT, cookies, session management, token refresh, and secure client-side storage.
• Strong understanding of API architecture, request lifecycle management, interceptors, retries, caching strategies, and resilient network communication.
• Experience optimizing frontend performance through bundle analysis, code splitting, lazy loading, rendering optimization, and profiling.
• Hands-on experience implementing comprehensive testing strategies using Jest, React Testing Library, Playwright, or similar tools.
• Experience debugging production applications using monitoring and observability platforms such as Datadog, Sentry, or equivalent, including Real User Monitoring (RUM).
• Strong knowledge of accessibility (WCAG), responsive design, and frontend best practices.
• Proven ability to make architectural decisions based on technical tradeoffs rather than implementation preferences.
• Advanced English communication skills.

Requirements

• Experience modernizing legacy frontend applications.
• Experience building shared design systems or frontend platforms.
• GraphQL and Apollo Client.
• Storybook.
• Analytics and experimentation platforms.
• Payment integrations (Stripe, PayPal).
• Experience working across multiple frontend applications within a platform engineering team.

Benefits

• 100% Remote Work: Enjoy the freedom to work from the location that helps you thrive. All it takes is a laptop and a reliable internet connection.
• Highly Competitive USD Pay: Earn an excellent, market-leading compensation in USD, that goes beyond typical market offerings.
• Paid Time Off: We value your well-being. Our paid time off policies ensure you have the chance to unwind and recharge when needed.
• Work with Autonomy: Enjoy the freedom to manage your time as long as the work gets done. Focus on results, not the clock.
• Work with Top American Companies: Grow your expertise working on innovative, high-impact projects with Industry-Leading U.S. Companies.
