About the Opportunity
We are hiring five exceptional Senior Software Engineers / Tech Leads for one of the UK's fastest-growing technology scale-ups.
Following significant growth and investment, the business is embarking on a major platform evolution programme, transitioning from a mature PHP-based architecture towards a modern, scalable, cloud-native ecosystem built around Go, APIs, distributed services, and event-driven architecture.
This is a rare opportunity to help shape the future technical direction of a highly successful SaaS platform used by global organisations.
We're looking for engineers who enjoy solving complex problems, influencing architecture, mentoring teams, and remaining hands-on with technology.

You'll lead technical delivery while helping drive a strategic technology transformation, modernising existing systems and building the next generation of products and services.
This role combines:

- Technical leadership
- Architectural ownership
- Mentoring and coaching
- Cloud-native platform development
- Full-stack product delivery
You'll work closely with Engineering, Product, Platform, and Architecture teams to build highly scalable solutions capable of supporting continued rapid growth.
What You'll Be Doing
- Leading and mentoring teams of talented software engineers
- Driving engineering best practices around Object-Oriented Design, SOLID principles, clean architecture, and maintainable code
- Designing and building scalable APIs and backend services
- Helping evolve a large PHP platform towards modern Go-based microservices
- Contributing across the full stack, from backend services through to customer-facing applications
- Influencing technical strategy, architecture, and platform direction
- Working closely with Product teams to deliver business-critical features
- Supporting CI/CD, cloud infrastructure, observability, and platform reliability initiatives
- Taking ownership from concept through design, development, testing, deployment, and ongoing optimisation
- Playing a key role in hiring and developing future engineering talent
