Lead Frontend Engineer

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
