About the Role

Role Summary

We are seeking a strong Frontend Software Engineer to build and evolve high-quality, high-performance web experiences using Next.js, React, TypeScript, and JavaScript.

This role goes beyond traditional frontend development. The ideal candidate will have a deep understanding of web performance, Core Web Vitals, browser fundamentals, rendering strategies, caching, networking, APIs, and the end-to-end web request lifecycle.

The candidate will be expected to think from first principles, make sound engineering trade-offs, build scalable and reusable frontend foundations, and collaborate closely with Product, Design, Backend, and Infrastructure teams.

Responsibilities

• Build and evolve web applications using Next.js, React, TypeScript, and JavaScript, with strong engineering foundations.
• Own and continuously improve web performance, with a deep understanding of Core Web Vitals including LCP, INP, CLS, and TTFB.
• Work with modern rendering strategies including SSR, SSG, CSR, hydration, caching, and resource loading.
• Use browser profiling, Lighthouse, RUM, observability, and profiling tools to identify bottlenecks and improve real-user performance.
• Understand and optimise the complete web journey from CDN and caching through server rendering, APIs, browser execution, and the final user experience.
• Build reusable frontend foundations, patterns, and components that can scale across products and teams.
• Make thoughtful engineering decisions by evaluating performance, scalability, maintainability, reliability, and cost.
• Challenge assumptions, unnecessary dependencies, excessive JavaScript, expensive rendering, and complexity that does not add value.
• Partner closely with Backend, Infrastructure, Design, and Product teams to solve problems end-to-end.
• Take a product-oriented approach by understanding how the complete experience works, performs, and feels to the user.
• Move with pace by building, shipping, measuring, learning, and continuously improving.
• Effectively leverage AI for coding, debugging, profiling, testing, exploration, and understanding unfamiliar systems, while maintaining ownership of engineering decisions.

Qualifications

Required Qualifications

• 3–5 years of software engineering experience with strong frontend and web fundamentals.
• Strong hands-on expertise in Next.js, React, TypeScript, and JavaScript.
• Deep understanding of browser fundamentals, rendering, networking, caching, and web performance.
• Strong understanding of Core Web Vitals with practical experience diagnosing and improving web performance.
• Hands-on experience with SSR, SSG, CSR, hydration, and modern Next.js rendering and caching patterns.
• Ability to understand when to use different rendering approaches based on the problem and product requirements.
• Comfortable using RUM, profiling, observability, and performance-debugging tools.
• Understanding of the infrastructure behind modern web applications, including CDNs, cloud, caching, deployments, APIs, and edge/server-side execution.
• Ability to reason about performance, scalability, maintainability, reliability, and cost, beyond UI implementation.
