About Office 21

Office 21 is a London-based IT support and infrastructure company. We are a small but fast-growing team looking after around 26 clients across professional services, venture capital, law, manufacturing, technology and marketing. We run and support modern infrastructure across Microsoft 365, Google Workspace, Azure, virtualisation, networking and security, and we are bringing on larger and more complex clients as we grow.

This is a hire to add real senior technical weight to the team.

The role

This is a senior, hands-on technical role. You will be our most senior engineer on the tools, the top escalation point for the team, and the person who leads our larger infrastructure and cloud projects from start to finish.

Alongside the technical work, you will give the engineering team day-to-day direction, answer the questions that come up during the day and keep work moving. Formal line management of the team sits with the Service Delivery Director, so your leadership here is technical rather than people management. You will also be a confident, credible point of contact for our clients, including senior stakeholders at larger accounts.

One of our immediate priorities is providing senior support for a client with a large Azure and Azure Virtual Desktop estate, so strong hands-on Azure and AVD experience matters for this role.

Roughly, expect the mix to be around 70% hands-on technical and project delivery, and 30% technical leadership and client-facing work.

What you will be doing

• Acting as the senior technical escalation point across our client base
• Leading larger infrastructure, cloud and migration projects end to end
• Providing senior support for a major Azure and AVD environment
• Giving the engineering team day-to-day technical direction and unblocking their work
• Working closely with our project manager to deliver complex projects to a high standard
• Being a confident, client-facing point of contact for senior stakeholders
• Keeping documentation to a high standard and handling privileged and admin access responsibly
• Occasional planned out-of-hours and weekend work for project cutovers and major incidents, with time off in lieu

What we are looking for

• Significant experience in an MSP or across multiple client environments
• Strong, hands-on Azure experience including Azure Virtual Desktop (design, build, support and migrations)
• Solid Google Workspace and Google Cloud experience
• Good grounding in identity and security (SSO, conditional access, MFA and endpoint management)
• A track record of delivering large infrastructure and migration projects independently
• Genuinely personable and client-facing, able to speak with conviction to non-technical decision-makers and hold your own in front of senior clients
• Sound judgement when handling privileged and administrative access
• Comfortable giving technical direction to a small team

Nice to have

• Relevant certifications (Azure Administrator or Architect, Google, or a recognised security certification)
• Exposure to any of our wider stack: FortiGate, Proxmox, Cloudflare Zero Trust, FreePBX or HaloPSA
• Previous experience mentoring or informally leading other engineers

What we offer

• Salary of 50,000 to 56,000 depending on experience, plus a discretionary bonus
• 25 days holiday plus bank holidays
• Private healthcare
• Genuinely varied and technically interesting work, with real ownership of major projects
• A small, capable team where senior people have influence and are not lost in a large hierarchy
• Room to grow as the company grows
