Principal Software Engineer

Method Resourcing are supporting a well-established tech company as they kick off a major platform rebuild and modernisation. After years of growth and acquisitions, they're unifying multiple products into a single, event-driven architecture and they need a Principal Engineer to shape it.

You'll be the technical authority across a multi-year transformation: breaking down a large monolith, designing high-scale distributed systems, and helping build a platform processing millions (eventually hundreds of millions) of daily events.

This is a hands-on, high-impact role at the top of the engineering track, blending deep technical design, coding, mentoring, and architectural decision-making.

What you'll work on:

• Designing scalable, cloud-native distributed systems

• Leading technical decisions and solving complex engineering problems

• Driving an event-driven microservices transformation

• Setting engineering standards and best practices

• Pairing, reviewing, and mentoring across teams

• Strong experience with distributed systems at scale

• Deep technical ability with modern languages and cloud tooling

• Solid understanding of architecture & microservice design

• Balance of hands-on coding and technical leadership

• Curiosity and a passion for modern engineering practices

You'll be at the centre of a complete platform rebuild with big technical challenges, strong leadership support, and a highly lucrative total package.
