Support Engineer

Job description

This is an on-site role.

When a hospital's workloads matter most, who do they call? At 3verest, it's a named engineer — not a ticket queue.

We run sovereign cloud infrastructure that healthcare depends on every hour of every day, and we're hiring two Cloud & Systems Support Engineers in London to keep it healthy.

This is a broad, hands-on role. One hour you're getting a clinician back into their account; the next you're diagnosing a storage fault on the infrastructure their department runs on. You'll be the human face of our concierge model — the person people come to, not a queue they wait in. Because we serve healthcare, reliability and discretion aren't optional. They're the job.

This is an on-site role. You'll be stationed in person at customer premises in London, and spend some of your time in our own office alongside the wider team. We're flexible when life genuinely needs us to be — the washing machine is being delivered, the broadband engineer is coming, something that simply can't be moved — just let us know and work from home that day.

Those are the exceptions, though, not the pattern. The preference is to be there in person, and we're upfront about why: our concierge model depends on engineers being present with the people they serve, and this is a role you'll grow in fastest by being in the room.

• Act as a named first- and second-line engineer for the customer teams you support — the person they come to, not a ticket queue.
• Provide day-to-day IT support to staff on site: laptops, accounts, access, printers, telephony, the lot.
• Administer Microsoft 365 and Entra  — user accounts, licensing, Exchange, SharePoint and Teams.
• Administer Windows Server and Windows desktop estates — builds, patching, group policy, endpoint management.
• Manage identity and access, including Duo MFA, and run the joiner/mover/leaver process cleanly.
• Administer 3CX telephony.
• Support the Linux systems and cloud infrastructure underpinning customer environments — patching, hardening, backup and recovery.
• Triage, diagnose and resolve infrastructure, systems, networking and platform incidents within agreed SLAs.
• Participate in a follow-the-sun on-call rotation for critical healthcare workloads.
• Write and improve runbooks, knowledge-base articles and automation that remove repeat work.
• Uphold our compliance posture (ISO 27001, SOC 2, NHS DSPT, GDPR, HSCN) in every action you take.

• Hands-on IT support experience in a mixed Windows and Linux environment.
• Solid Microsoft 365 and Windows Server administration — accounts, licensing, group policy, patching.
• Working knowledge of networking fundamentals — DNS, TCP/IP, VPN, firewalls, Wi-Fi.
• Experience with identity and MFA tooling (Duo, Entra  similar).
• Exposure to Linux, and a real appetite to go deeper into cloud and infrastructure.
• Excellent communication and patience — you can help a frustrated clinician and a demanding CTO in the same afternoon, and both feel looked after.
• A calm, methodical approach to incidents, and genuine care for the people on the other side of the system.

• VoIP/telephony administration (3CX or similar).
• Experience supporting regulated industries (healthcare, finance, government) or PACS/VNA/imaging workloads.
• Cloud or virtualisation exposure (AWS, Azure, VMware, Open Stack), containers, or scripting (Power Shell, Bash, Python).
• Cloud, systems or platform certifications — and if you don't have them yet, we'll sponsor them.

£35,000–£45,000 depending on experience, plus pension contributions, a learning budget and certification sponsorship.

Our engineers work inside healthcare environments, close to the most sensitive data there is. Every offer is conditional on pre-employment vetting: identity and right-to-work verification, employment reference checks, and a criminal records check (DBS) at the level appropriate to the role. Some customer sites require additional clearance before you can begin work there.

Having a criminal record will not necessarily bar you from working with us — we consider each case individually, in line with the Rehabilitation of…
