Impact & contribution:

We are seeking an experienced Senior Software Engineer – Frontend to design, build, and deliver modern, scalable, secure, and accessible web applications using Next.js, React, and TypeScript.

You will contribute to the development of high-quality digital experiences using modern server-first frontend architecture, reusable design systems, strong engineering practices, and automated testing. You will work within a monorepo environment, collaborate closely with engineers, designers, and product teams, and help drive engineering standards across performance, accessibility, security, observability, and maintainability.

Key Responsibilities

• Design and develop scalable, production-grade web applications using Next.js 16+, React 19+, and TypeScript 5.9+

• Implement modern Next.js App Router patterns including layouts, nested routing, loading and error states, Server Components, Client Components, and server-side data fetching

• Apply appropriate React Server Component (RSC) and client-side rendering patterns to optimise application performance and user experience

• Develop reusable frontend components and shared libraries within a Turborepo and pnpm-based monorepo

• Build user interfaces using CSS/SCSS Modules and enterprise design systems such as Lumen (@lumen/react)

• Implement effective state-management strategies using Zustand, SWR, URL parameters, and server-first approaches

• Develop comprehensive automated tests using Vitest, React Testing Library, and Playwright

• Integrate frontend applications with APIs and gateway solutions, including Kong, JWT-based authentication, and declarative gateway configuration

• Implement feature flag-driven development using LaunchDarkly across server-side and client-side application flows

• Build accessible digital experiences aligned with WCAG 2.1 AA standards

• Apply secure development practices aligned with OWASP Top 10 and enterprise security standards

• Implement application observability using OpenTelemetry, OTLP, and structured logging

• Maintain high engineering quality through modern tooling including Oxlint, Oxfmt, and React Compiler

• Participate in code reviews, technical discussions, solution design, and PR-based engineering collaboration

• Follow disciplined Git practices including conventional commits, rebasing, branching, and pull-request workflows

• Collaborate with UX, design, product, backend, platform, and engineering teams to deliver consistent and maintainable customer experiences

Required Skills:

• Strong hands-on experience in TypeScript and React, with a solid understanding of modern React architecture and development practices

• Strong experience with Next.js App Router, including layouts, loading states, routing, Server Components, Client Components, server actions and/or server-side data fetching

• Good understanding of React Server Components (RSC) and the ability to determine when server-side versus client-side components should be used

• Experience developing applications using TypeScript in strict mode

• Experience working within monorepo architectures, preferably using Turborepo, pnpm workspaces, shared packages, and reusable libraries

• Strong automated testing experience using tools such as Vitest, React Testing Library, and Playwright

• Experience with frontend state and data-management approaches such as Zustand, SWR, URL-based state, and server-first patterns

• Experience building reusable UI components using CSS/SCSS Modules and enterprise design systems

• Strong understanding of web accessibility and WCAG 2.1 AA standards

• Understanding of secure coding practices and OWASP Top 10

• Strong Git and collaborative development practices including conventional commits, rebase workflows, code reviews, and PR-based development

• Experience with modern JavaScript/TypeScript engineering tooling, linting, formatting, and build optimisation

• Strong problem-solving skills with a focus on clean, maintainable, performant, and reusable code

Nice to Have:

• Experience with micro-frontend architectures or API gateway patterns using technologies such as Kong or NGINX

• Experience with LaunchDarkly or similar feature management and feature flag platforms

• Exposure to OpenTelemetry, OTLP, structured logging, tracing, and application observability

• Experience with Storybook or developing and maintaining enterprise design systems

• Knowledge of banking and regulatory domains including KYC, AML/CTF, FATCA, and CRS

• Understanding of JWT-based authentication and secure API integration patterns

• Experience working with large-scale enterprise applications and distributed engineering teams
