About You:

You’re a confident, hands-on infrastructure engineer who thrives in technically complex environments. You bring a structured approach to problem-solving, a passion for improving systems, and a calm, proactive mindset, especially when tackling critical issues.

You’re equally comfortable working independently or as part of a team, and you understand how resilient infrastructure underpins business success. With a strong sense of ownership, you take pride in seeing tasks through, and you’re always looking ahead identifying issues before they escalate, suggesting improvements, and supporting others along the way.

You have experience managing live environments and responding to incidents with urgency and care. Certifications are a bonus but it’s your real-world know-how, communication skills, and commitment to quality that set you apart.

About The Team:

You’ll be joining a close-knit, experienced Platform team that spans 1st to 4th line support. The team supports our core infrastructure that delivers services to tens of thousands of customers across the UK and beyond.

The culture is supportive, down to earth, and highly skilled. We value curiosity, collaboration, and knowledge sharing. Everyone in the team has a voice, and we’re constantly looking for ways to innovate and improve together.

About The Role:

We’re looking for a hands-on Technical Platform Engineer (2nd Line) to join our Platform team and help manage and evolve our hybrid infrastructure estate. This is a key technical role where you'll provide support, drive proactive improvements, and contribute to platform resilience across our services.

You’ll take ownership of escalated incidents, lead patching and infrastructure upgrades, and ensure our systems remain secure, available, and high-performing. The role also includes participation in our on-call rota, with compensation provided separately.

This is a fantastic opportunity for an experienced engineer who thrives in complex environments, enjoys solving challenging problems, and wants to be part of a supportive, forward-thinking team.

• Manage and resolve escalated support tickets in line with SLAs

• Attend the data centre as required for hardware or network work
• Maintain system documentation and support compliance with ISO27001 and Cyber Essentials
• Participate in the out-of-hours on-call rota for critical incidents
• Mentor junior team members and contribute to platform tooling and improvements

• Escalated issues are resolved swiftly and thoroughly, with strong feedback from stakeholders
• Proactive monitoring reduces incidents before they arise
• Infrastructure upgrades and changes are delivered smoothly, with minimal disruption
• The platform remains secure, compliant, and well-documented
• You’re seen as a reliable, collaborative engineer who contributes beyond the day-to-day
