About the job
We’re working with a well-established, private equity-backed technology business operating across multiple international markets. The company builds and delivers critical, high-availability systems within sectors that demand reliability, scalability and long-term performance. Following continued growth and system evolution, they are looking to strengthen their engineering team with a senior hire.
This is a senior-level Software Engineer role focused on designing, building and evolving large-scale, high-capacity systems within a complex, distributed environment.
The Role
- Design and build scalable, event-driven and distributed systems
- Translate product requirements into robust technical solutions and architecture
- Contribute across the full development lifecycle: planning, design, implementation and optimisation
- Maintain a balance of ~70% hands-on coding and ~30% architecture, planning and collaboration
- Work closely with Product and Engineering teams to define and refine system requirements
- Ensure high standards across code quality, testing and maintainability
- Support and mentor other engineers, contributing to coding standards and best practices
- Participate in code reviews, technical discussions and continuous improvement initiatives
- Troubleshoot complex issues across the system lifecycle
Tech Environment
- Predominantly PHP, including legacy systems (KPHP) transitioning to Laravel
- Some C# exposure – not essential but beneficial
- Backend-focused, with rare occasional frontend interaction (non-UI heavy systems)
- Event-driven architecture and distributed systems at scale
What They’re Looking For
- Strong fundamentals in software engineering and system design
- Experience building and scaling backend systems in complex environments
- Ability to design for performance, reliability and future scalability
- Comfortable working across legacy and modernising tech stacks
- Experience working with Product teams on requirements and planning
- Solid understanding of coding standards, testing (TDD beneficial), and software quality
- Mentoring or guiding other engineers
- Exposure to distributed systems or high-throughput environments
- Frontend experience is a bonus, not a requirement
Salary & Benefits
- ~£75,000 base salary
- ~5% annual bonus
- ~ Benefits package included
Working Setup
- ~ Hybrid environment with flexibility (typically up to 3 days in office, though this varies in practice and can be less)
Additional Notes
Strong emphasis on core engineering fundamentals over reliance on tooling such as AI. Candidates should be pragmatic, collaborative and technically grounded.
