Job Description

ABOUT THE OPPORTUNITY

Join a world-class technology consultancy where software is built by people, for people, creating high-performance systems that impact users worldwide. We're seeking a Frontend Software Engineer to join an agile, collaborative team where your voice matters as much as your code. You'll be a technical partner designing and building high-performance, secure, and scalable front-end solutions with strong focus on React, Next.js, and modern JavaScript including server-side rendering for seamless, isomorphic applications.

You'll build applications using React.js and Next.js with server-side rendering concepts, managing state with Redux or similar solutions, and integrating with both GraphQL and REST APIs. Strong emphasis on testing using frameworks like Jest and React Testing Library, performance monitoring with tools like New Relic, Grafana, or Core Web Vitals metrics. Working primarily in Azure cloud environments, you'll ensure products reach everyone through accessibility standards and optimization. Expected travel varies by project (0-15%).
