You will work closely with backend engineers, UX designers, and product owners to deliver seamless digital experiences to our customers.

• Develop and maintain responsive, high-performance front end applications using React, TypeScript, and Tailwind CSS.
• Implement modern rendering strategies including SSR (Server-Side Rendering), CSR (Client-Side Rendering), and ISR (Incremental Static Regeneration) to optimise performance and SEO.
• Monitor and improve front end performance using Web Vitals and Lighthouse, ensuring core web vitals meet banking-grade standards.
• Collaborate with backend teams working with Node.js, Rust, Python, and AWS Serverless to integrate RESTful APIs and real-time data.
• Work with databases such as MongoDB and MySQL to understand data flow and optimise front end data fetching.
• Contribute to full-stack features when needed, leveraging experience with Leptos, Axum, Tokio, Serde, or Tauri.
• Ensure front end code is secure, accessible, and compliant with banking security standards (e.g., OWASP, MAS TRM guidelines).
• Participate in code reviews, technical design discussions, and agile ceremonies.
• Mentor junior developers and contribute to front end architecture decisions.

Key Requirements

• Strong experience with React, TypeScript, and Tailwind CSS.
• Deep understanding of SSR, CSR, and ISR (experience with Next.js or similar frameworks is highly desirable).
• Proven ability to optimise front end performance using Web Vitals and Lighthouse.
• Experience with state management (e.g., Redux, Zustand, Context API).

• Working knowledge of Node.js and experience integrating with backend services.
• Familiarity with Rust, Python, or AWS Serverless is a strong plus.
• Experience with MongoDB and MySQL (understanding data modelling and query optimisation for front end use).
• Exposure to Leptos, Axum, Tokio, Serde, or Tauri is advantageous.
