Principal Front End / React Developer

Up to £85,000 | Remote (1 day per month required in Manchester)

We are supporting a UK technology organisation seeking a Principal Front End Developer to take a senior, hands-on role within their engineering team. This position combines deep technical ownership with the ability to guide, influence and raise standards across multiple long-lived products.

You will act as the senior front-end authority across the business, working closely with other principals, tech leads and cross-functional teams. Key aspects of the role include:

• Leading architectural and front-end direction across several products

• Hands-on development using React, TypeScript and a broad modern front-end toolkit

• Improving a large, evolving front-end estate with inconsistent legacy patterns

• Being the go-to person for complex front-end solving

• Mentoring engineers from apprentice level right through to senior/lead

• Supporting high standards in testing, automation and release processes

• Helping bring consistency and clarity to the wider front-end approach

This role suits someone who enjoys improving real product systems rather than purely working on greenfield builds.

Required Experience

• Deep React and TypeScript experience in mature, complex product environments

• A track record of influencing architecture, standards and long-term direction

• Experience mentoring both junior engineers and highly capable seniors

• Exposure to automated testing and tools such as Playwright
