## Description

We're supporting an established, technology-driven organisation that is investing heavily in the future of its engineering function. Following continued growth and a major platform transformation programme, they are looking to appoint a Principal Software Engineer to play a key role in defining both the technical direction and engineering culture of the business.

This is an opportunity to join at a pivotal stage, working within a highly experienced team that values innovation, collaboration and modern software engineering practices.

THE ROLE:

This is a highly influential technical leadership role where you'll help shape the future of a modern, large-scale platform whilst remaining hands-on with development.

You'll lead the design and delivery of scalable backend services, APIs, integrations and data flows, whilst providing architectural guidance across the wider engineering team. Although the role is backend-focused, you'll also maintain strong involvement across the full stack, working with modern frontend technologies and cloud infrastructure.

Working closely with senior stakeholders, product teams and fellow engineers, you'll help establish engineering standards, drive adoption of AI-assisted development practices, and mentor other engineers as the team continues to grow.

This role offers genuine autonomy, giving you the opportunity to influence technology decisions, engineering processes and long-term platform strategy.
