Salary: Up to £110,000 + Bonus & Benefits
We’re looking for a Principal Software Engineer to join a global technology business whose platforms underpin consumer experiences used by millions of people every day. This is an established, scaled business with a genuinely global reach and this role sits at the heart of their core engineering capability.
This isn’t a purely strategic seat. You’ll have genuine technical authority over a business-critical API platform while staying close to the engineering, partnering with skilled squads to solve complex distributed systems challenges at scale.
Key Responsibilities
- Set the technical direction for a large-scale API platform across both synchronous and event-driven services
- Drive continuous improvement across security, observability, performance, and long-term maintainability
- Mentor and develop engineers and technical leads across multiple teams
- Work closely with Product and Delivery leadership to keep engineering strategy aligned with broader business goals
- Champion strong engineering fundamentals — testing, CI/CD, infrastructure as code, and clean architecture
- Identify practical ways to bring emerging technologies, including AI tooling, into everyday engineering workflows
Key Requirements
- A strong track record delivering large-scale distributed systems in cloud environments
- Deep knowledge of API design – REST and GraphQL, and substantial hands‑on experience with Kafka in a production environment
- Solid cloud platform experience, particularly AWS, and comfort with containerised infrastructure
- Proficiency in TypeScript across a modern backend stack
- Experience leading and influencing across multiple engineering teams, not just within a single squad
- A genuine care for code quality, sustainable architecture, and long-term thinking over short-term delivery
- A collaborative, mentoring leadership style that brings the best out of the people around you
- An interest in how AI is changing the way engineering teams work
- Enterprise CRM experience would be an advantage
What’s on Offer
- Salary Up to £110,000 plus bonus
- Genuinely flexible hybrid working arrangements
- Generous parental leave and family‑friendly policies
- Strong support for career development and progression
This is the right role for a Principal Engineer who is ready to move beyond squad-level impact and take on something bigger – shaping the architecture, the team, and the direction of a platform that matters at real scale.
