• Investigating issues across live production systems and services
• Working across multiple technology stacks which could include PHP, .NET, Python, JVM and cloud-based applications
• Performing root cause analysis and supporting long-term fixes
• Collaborating with engineering, infrastructure and delivery teams
• Supporting operational stability, monitoring and service improvements
• Mentoring and supporting less experienced engineers within the support function
• Participating in an on-call rota (1 in 4 weeks)

What we’re looking for

• 5+ years’ experience in Application Support, Software Engineering or Production Support environments
• Strong troubleshooting and debugging capability across distributed applications
• Previous experience supporting live production systems at L2/L3 level
• Experience across multiple languages/technology stacks such as: PHP, .NET / C#, Python etc
• APIs / integrations
• Comfortable reading and understanding code to diagnose issues
• Experience working in complex enterprise or public sector environments
• Strong communication and stakeholder management skills
• Ability to mentor and support junior engineers
• Experience within ITIL/service management environments would be highly beneficial

Desirable Experience

• Cloud platforms (Azure and/or AWS)
• Monitoring/logging tools
• CI/CD environments
• Incident management and post-mortem processes
• Consultancy or managed service environments

This is an excellent opportunity for a well-rounded engineer who enjoys solving complex problems, supporting mission-critical systems and working across a broad technology landscape within a highly collaborative consultancy environment.
