Salary: Up to £65,000 + £7,000 bonus
Security Clearance: Must be eligible for UK Developed Vetting (DV)
We’re hiring a Site Reliability Engineer to join a high-performing engineering environment delivering critical, complex systems. This role sits at the intersection of software engineering and operations, with a strong focus on automation, scalability, and system resilience.
This is an excellent opportunity for someone with a software engineering background who is looking to move into a more systems-focused, reliability-driven career path without losing their hands-on technical edge.
As an SRE, you’ll be responsible for ensuring the reliability, availability, and performance of mission-critical systems. You’ll apply software engineering principles to infrastructure and operations challenges, reducing manual effort through automation and improving system design.
Key Responsibilities Include:
- Supporting and maintaining live services, ensuring high availability and performance
- Automating operational processes to reduce manual intervention
- Monitoring, alerting, and observability improvements across systems
- Diagnosing and resolving incidents across the full technology stack
- Working closely with engineering teams to influence system design and reliability
- Participating in an on-call rota (project-dependent)
- Contributing to continuous improvement of DevOps and SRE practices
What We’re Looking For
We’re interested in candidates who bring a strong engineering mindset and enjoy solving complex systems problems.
Core Experience:
- 2+ years commercial experience in this area
- Background in software engineering (e.g. Java, JavaScript, or similar)
- Experience working with cloud platforms (AWS, Azure, or similar)
- Strong Linux/Windows command line skills (Bash, PowerShell)
- Understanding of distributed systems, scalability, and resilience
- Experience with monitoring/observability tools (e.g. ELK stack or similar)
- Familiarity with containers and microservices (e.g. Docker)
- Experience troubleshooting across infrastructure and application layers
Desirable:
- Exposure to 2nd or 3rd line support environments
- Knowledge of CI/CD and deployment tooling
- Experience with infrastructure as code or configuration management tools
- Understanding of ITIL or service management practices
Additional Requirements
- Willingness to participate in on-call support (depending on project)
If you’re a software engineer looking to broaden your impact into reliability, systems, and large-scale infrastructure, this role offers a strong platform to do exactly that.
