Lead Frontend Engineer
Posted Updated
Description
We are hiring a Lead Frontend Engineer to own frontend architecture, performance strategy, real-time communication systems, and scalable UI architecture across complex web platforms. This role requires deep technical leadership, hands-on expertise in Next.js and modern React, and the ability to design systems that scale sustainably over time. The ideal candidate understands architectural trade-offs in rendering models, styling strategies, and state management, and can drive frontend excellence across teams.
Key Responsibilities:
- Design and own scalable frontend architecture for complex, high-traffic web applications.
- Define application structure, module boundaries, shared component libraries, and long-term maintainability strategies.
- Drive architectural decisions around rendering models (SSR, SSG, ISR, CSR), styling systems, and state/data flow.
- Implement architectural patterns such as component-driven development, domain-based organization, and micro-frontends where applicable.
- Build and maintain production-grade applications using Next.js and modern React with TypeScript.
- Design and evolve reusable component libraries and enterprise-level design systems.
- Architect and manage complex state systems, clearly separating server state, client state, and UI state.
- Implement real-time communication features using WebSockets, SSE, or WebRTC with proper reconnection and consistency strategies.
- Own frontend performance optimization including code splitting, bundle analysis, memoization, virtualization, and Core Web Vitals improvements.
- Ensure frontend security best practices including XSS, CSRF mitigation, secure authentication flows, and CSP implementation.
- Evaluate and integrate UI, form, validation, and data visualization libraries aligned with scalability goals.
- Work closely with DevOps on CI/CD pipelines, CDN strategies, caching, edge deployments, monitoring, and observability.
- Lead code reviews focusing on architecture quality, performance, and long-term maintainability.
- Mentor frontend engineers and establish coding standards, best practices, and architectural documentation (ADRs, diagrams).
- Collaborate with backend engineers and solution architects in cross-functional design discussions.
Requirements
- 10+ years of frontend or web engineering experience.
- Minimum 3+ years of production-level experience with Next.js.
- Expert knowledge of React, TypeScript, and modern browser fundamentals.
- Deep expertise in frontend architecture, scalable UI systems, and design systems.
- Strong experience with advanced state management patterns and real-time frontend systems.
- Proven track record of leading frontend architecture at scale in production environments.
- Experience with performance tooling such as Lighthouse, Web Vitals, and browser profiles.
- Strong understanding of frontend security principles and secure coding practices.
- Bachelor’s degree in Computer Science or related field preferred.
