Description
London – The Shard | Hybrid – 3 days onsite
- Quick interview process - immediate start
We're 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.
You'll 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 modernize the technology estate. You'll work closely with engineering, security, and architecture teams and have the opportunity to influence how the environment develops.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The role requires 3 days per week onsite at The Shard, with the remaining days worked remotely.
We're 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 you'll be working with
You'll 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
You'll act as a senior escalation point for Level 2 engineers, troubleshoot complex incidents and root causes, implement infrastructure changes, and identify opportunities for automation, standardization, and technical improvement.
You'll 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
We're 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.
You'll 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.
You'll 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 modernization initiatives would be particularly valuable.
