The Opportunity

Join a global SaaS organisation in the midst of a major digital transformation - a once-in-a-generation modernisation of how technology enables intelligent marketplaces, data-driven decisioning, and seamless customer journeys across Europe.

This is a principal-level engineering role at the centre of a bold, multi-country digital initiative, building a new platform that is reshaping how industries connect, trade and operate in real time.

Why It's Exceptional

You will be joining a business investing heavily in product innovation and cloud technology, working with talented engineers who are redefining how large-scale platforms are built and run. This is a high‑influence position, the ideal move for a senior engineer ready to take architectural ownership, mentor others, and drive the engineering vision behind a major European programme.

The Mission

As Principal Front-End Engineer, you’ll set the technical direction for a large, distributed engineering team, ensuring the delivery of elegant, scalable, and performant user interfaces built around modern React and TypeScript frameworks. You’ll work hand‑in‑hand with product, UX and back‑end engineering teams to craft cloud-native solutions that scale across multiple markets and millions of transactions.

Key Responsibilities

• Define and lead the front-end architecture and strategy for a complex digital platform.
• Build and evolve modern, reusable, and accessible UI components using React and related technologies.
• Champion engineering best practices including CI/CD, automated testing, and code quality standards.
• Collaborate with back‑end and DevOps teams to ensure seamless integration and deployment in a cloud environment (Azure or similar).
• Mentor and develop engineers across multiple squads, inspiring technical excellence and knowledge sharing.
• Influence platform-wide design and contribute to strategic technology decisions across the product suite.

What You’ll Bring

• Expert-level experience in React, TypeScript, and modern JavaScript frameworks.
• Strong understanding of API integration, performance optimisation, and modern UI engineering.
• Solid grasp of cloud-based development (preferably Azure) and familiarity with DevOps pipelines (e.g., GitHub Actions).
• Exposure to .NET back-end environments or similar enterprise stacks.
• Deep understanding of testing methodologies and automation principles.
• Exceptional communication skills and the ability to influence at all levels.
• A proven track record of technical leadership within large-scale, product-driven teams.

Package & Benefits

• Salary: up to £100,000 per annum
• Bonus: up to 30%
• Car Allowance
• Flexible hybrid working (North England hubs – Leeds + Manchester)
• Career-defining opportunity within a global transformation programme

The Environment

This organisation is building a truly modern digital ecosystem – combining data, cloud technology and automation to power smarter, faster, and more sustainable business models.
