Were looking for an experienced Senior Infrastructure Engineer to join Wanstor and become part of our dedicated technology team supporting one of our customers from their offices in The Shard, London.
This is a great opportunity for an experienced L3 engineer who wants to move beyond purely reactive support and take greater ownership across infrastructure, projects, technical change, security, resilience and continuous improvement.
Youll be one of the senior technical people within the environment, acting as an escalation point for complex issues while also contributing to infrastructure projects and helping to improve and modernise the technology estate. Youll work closely with engineering, security and architecture teams and have the opportunity to influence how the environment develops.
The role requires 3 days per week onsite at The Shard, with the remaining days worked remotely.
Were looking for someone who can start as soon as possible and will be running a quick and straightforward interview process for suitable candidates.
Key Responsibilities
What youll be working with
Youll support and develop a modern hybrid infrastructure environment covering:
- Microsoft Azure
- Microsoft 365 and Exchange Online
- Active Directory and Entra ID
- Microsoft Intune and Autopilot
- Windows Server
- VMware
- Backup and disaster recovery
- Endpoint and infrastructure security
- Monitoring and infrastructure resilience
Youll act as a senior escalation point for Level 2 engineers, troubleshoot complex incidents and root causes, implement infrastructure changes and identify opportunities for automation, standardisation and technical improvement.
Youll also contribute to infrastructure projects from design through to implementation and operational handover, working closely with Technical Engineering, Operational Security and Enterprise Architecture teams to deliver the wider technology roadmap.
Skills, Knowledge and Expertise
Were looking for someone with strong hands-on experience across Microsoft infrastructure who has operated at Senior Infrastructure Engineer, 3rd Line Engineer, Systems Engineer or a similar level.
Youll ideally bring strong experience across Azure, Active Directory/Entra ID, Microsoft 365, Intune and Windows Server, alongside broader infrastructure knowledge such as VMware, backup/DR and endpoint security.
Youll need to be comfortable owning technical problems through to resolution, working within structured change processes and communicating confidently with both technical teams and business stakeholders.
Experience delivering infrastructure projects, migrations, platform improvements or modernisation initiatives would be particularly valuable.
