Project Overview

We are partnering with a client in the workforce development and upskilling space to build a groundbreaking platform that fuses AI and human insights to deliver immersive workplace simulations. These simulations are designed to help users master critical interpersonal and cognitive skills, improving individual performance, team productivity, and organizational effectiveness.

Role Overview

In this role, you will focus primarily on building user-facing features in React.js, helping modernize and elevate the product experience as the client migrates to a scalable new platform. While there may be some backend work using NestJS, your primary focus will be on developing high-performance, component-driven UIs that support the product’s evolution and scale. 

You’ll collaborate closely with Product, Design, and Engineering teams in an agile environment. This is a hands-on engineering role where you’ll write new frontend services in React.js, help ensure UI continuity throughout the migration process, and contribute to frontend architecture decisions. You’ll also be expected to bring a strong sense of ownership, integrate AI tools into your workflow, and actively share knowledge with the team.

As this is a new client engagement, it's crucial that you bring a strong technical presence and proactive mindset to help us deliver excellence from day one.

Key Responsibilities

• Collaborate with Design and Product teams to build intuitive, responsive, and scalable React.js interfaces in an agile development environment.
   
• Develop new frontend services and UI components that align with the platform’s migration and future growth.
   
• Ensure smooth user experience continuity during the migration from legacy systems to the new architecture.
   
• Contribute to frontend architecture and help define best practices around code quality, performance, and modular design.
   
• Integrate AI-assisted tooling to increase productivity and elevate the user experience.
   
• Collaborate with backend engineers working in NestJS and Java, ensuring seamless data flow and system integration.
   
• Participate in knowledge sharing through team events like lunch and learns to uplift technical capability across the org.
   
• Mentor junior engineers and help maintain high engineering standards throughout the team.
   

Minimum Requirements

• 7+ years of professional software engineering experience, with a primary focus on frontend development.
   
• 4+ years of hands-on experience building applications in React.js in production environments.
   
• Strong proficiency in JavaScript/TypeScript, with an understanding of modular UI architecture and modern React patterns (hooks, context, etc.).
   
• Experience integrating with backend APIs (especially REST and GraphQL).
   
• Strong experience with NestJS and willingness to contribute lightly to backend efforts as needed.
   
• Solid understanding of CI/CD tools (Jenkins or similar) and experience deploying frontend code to cloud environments (Azure/AWS).
   
• Experience leveraging AI tooling (e.g., GitHub Copilot, OpenAI APIs) in a real-world development environment.
   
• Track record of writing maintainable, testable, and scalable code using best practices.
   
• Strong communication skills and a team-oriented mindset.
