Timings: 11:00 AM – 8:00 PM IST

Compensation: Best in Industry

Role Overview :

We are hiring a Lead Frontend Engineer to own the architecture and delivery of large-scale, cloud-native web applications.

This is not a UI-only role you will drive frontend system design, performance engineering, and platform-level decisions across multiple products.

You will be responsible for building highly scalable, modular frontend architectures (Micro Frontends), ensuring low-latency, high-availability user experiences, and partnering with backend, product, and design teams to deliver production-grade SaaS platforms used at scale.

This role requires deep hands-on expertise, strong engineering judgment, and proven experience in building and operating frontend systems in production environments.

Key Responsibilities :

Architecture & System Design :

• Own and design frontend architecture for large-scale applications, including Micro Frontend ecosystems (mandatory)
• Define component architecture, state management strategies, and inter-app communication patterns
• Drive modularization, reusability, and long-term maintainability across multiple frontend applications
• Make critical decisions on frameworks, libraries, and architectural patterns

Development & Delivery :

• Build and ship production-grade applications using React.js, TypeScript, modern JavaScript (ES6+)
• Enforce clean code practices, strong typing, and scalable folder/code structures
• Implement robust API integrations, handling edge cases, failures, retries, and performance optimization
• Ensure cross-browser compatibility and responsive design at scale

Performance & Scalability :

• Optimize applications for low latency, fast load times, and high concurrency
• Implement code splitting, lazy loading, caching strategies, and CDN optimization
• Analyze and improve Core Web Vitals (LCP, CLS, FID) and real-user performance metrics

Collaboration & Product Thinking

• Work closely with UX/UI teams to translate design systems into high-quality, scalable UI components
• Partner with backend teams to define API contracts and data flow strategies
• Contribute to product decisions with engineering trade-offs

Leadership & Mentorship

• Mentor engineers and enforce engineering excellence standards
• Conduct code reviews focused on scalability, performance, and maintainability
• Drive a culture of ownership, accountability, and continuous improvement

Technical Skills (STRICT REQUIREMENTS)

Core Frontend

Expert-level proficiency in :

• React.js (hooks, lifecycle, performance patterns)
• TypeScript (mandatory for large-scale apps)
• Modern JavaScript (ES6+)
• HTML5, CSS3 (including Flexbox, Grid)
• Micro Frontend architectures (MANDATORY production use only)
• Component libraries / design systems
• State management (Redux / Zustand / Context API or equivalent)

Strong understanding of :

• Frontend scalability patterns
• Module federation / app composition

Cloud & Infrastructure :

• Experience working in cloud-native environments (GCP preferred / AWS acceptable)

Experience Requirements (NON-NEGOTIABLE)

• 10+ years of frontend engineering experience

Proven experience in :

• Building and scaling production web applications
• Owning frontend architecture (not just contributing)
• Working in product/SaaS environments

Demonstrated experience with :

• Micro Frontends in production (mandatory)
• Handling high-traffic or enterprise-scale applications
• Experience working in cross-functional, global teams

What Makes a Strong Fit :

• Has architected and scaled frontend platforms, not just built screens
• Demonstrates deep understanding of performance optimization and scalability

Has delivered measurable impact :

• Improved performance
• Reduced load times
• Enhanced user experience at scale
• Strong ownership mindset drives decisions, not just executes tasks
• Comfortable working in ambiguous, fast-paced product environments
• Ability to balance engineering excellence with product delivery speed

Implicit Disqualifiers (Used Internally for Screening) :

• Have only worked on UI implementation without architecture ownership
• Lack real Micro Frontend production experience
• Show only tool familiarity without depth
• Have no exposure to production-scale systems
• Primarily worked in support/maintenance roles
