Job description

Lead Software Engineer - Frontend
Cardiff / Hybrid
Up to £85,000 + excellent benefits

What You'll Do:

You'll take a lead role in shaping scalable, modular frontend applications using micro frontend architecture. Working across both frontend and backend-for-frontend (BFF) solutions, you'll design, deliver, and maintain secure and high-performing React and NestJS applications.

This is a hands-on leadership role where you'll drive engineering excellence, guide technical decisions, and support the development of reusable platforms. From mentoring developers to contributing to CI/CD and performance optimisation, you'll be instrumental in building cutting-edge digital experiences.

What You'll Bring:

• Proven expertise in React and TypeScript, with a deep understanding of component architecture and performance tuning
• Strong experience designing and delivering micro frontend solutions, including module federation and independent deployment strategies
• Hands-on experience with NestJS for BFF/API gateway patterns
• Familiarity with CI/CD practices and tooling such as Azure DevOps or GitHub Actions
• Solid understanding of frontend performance optimisation techniques (lazy loading, code splitting, caching)
• Proficiency in containerisation, orchestration, and infrastructure-as-code using Docker, Kubernetes, and Terraform
• Experience with cloud platforms, preferably GCP or Azure
• Working knowledge of modern testing tools including Jest, Vitest, and Playwright
• Strong leadership, mentoring, and technical decision-making capabilities

Why You Should Apply:

You'll join a forward-thinking company that champions diversity, progression, and innovation. With recognition as a Great Place to Work, you'll benefit from excellent flexibility, people-first values, and annual share awards. You'll also enjoy up to 38 days holiday, wellbeing initiatives, and a real opportunity to shape the direction of frontend architecture.
