Job summary

3verest runs sovereign cloud infrastructure for healthcare and is hiring a Cloud & Systems Support Engineer for a full-time, on-site position in Oxford. You will be the named engineer, handling day-to-day IT support, identity management, and infrastructure tasks across Windows, Linux, and cloud environments.

The role emphasizes reliability, discretion, and direct client engagement, with growth through hands-on experience and a strong compliance posture.

Qualifications

• 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 ID or 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.

Responsibilities

• Act as a named first- and second-line engineer for the customer teams you support.
• Provide day-to-day IT support to staff on site: laptops, accounts, access, printers, telephony, the lot.
• Administer Microsoft 365 and Entra ID — 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.
• Patch, harden, backup and recover; triage incidents within SLAs.
• Participate in a follow-the-sun on-call rotation for critical workloads.
• Write and improve runbooks, knowledge-base articles and automation.
• Uphold our compliance posture (ISO 27001, SOC 2, NHS DSPT, GDPR, HSCN).

Job description

3verest runs sovereign cloud infrastructure that hospitals, imaging networks and health-tech builders rely on every hour of every day — and we're hiring a Cloud & Systems Support Engineer in Oxford to keep those workloads running.

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 named engineer customers reach when it matters — the person they come to, not a queue they wait in. In healthcare, reliability and discretion aren't optional. They're the job.

Where you'll work

This is a full-time, five-day on-site role, based at a customer site in Oxford. 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.

What you'll do

• 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 ID — 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.

What you'll bring

• 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 ID or 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.

Nice to have

• 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, OpenStack), containers, or scripting (PowerShell, Bash, Python).
• Cloud, systems or platform certifications — and if you don't have them yet, we'll sponsor them.

Salary and benefits

£33,000–£43,000 depending on experience, plus pension contributions, a learning budget and certification sponsorship.

Pre‑employment vetting

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 Offenders Act. We ask for honesty upfront, and we treat what you tell us in confidence.

About 3verest

3verest builds sovereign cloud infrastructure for healthcare. Founded in 2016, we operate across 19 sovereign regions on four continents with 99.999% uptime, serving global imaging OEMs, health systems and national health bodies. We refuse the trade the market says you have to make: hyperscaler scale without sovereignty, or local sovereignty without reach. We built a third path — sovereign on every layer, global in reach, with concierge service and sovereign AI inside the boundary.

Sovereign by design. Human by purpose.

Why you’ll want to work here

• A mission with meaning — the systems you support protect the most sensitive data in the world.
• Named engineers, not a ticket queue — your work is seen, argued and credited.
• Room to grow — a learning budget, sponsored certifications, and senior engineers who’ll actually teach you. If you want to move from support into cloud and infrastructure, this is the job that gets you there.
• Sovereign‑scale exposure — 19 regions, four continents, and a serious compliance posture (ISO 27001, SOC 2 Type II, NHS DSPT, GDPR, HSCN, GAIA‑X).

Equal opportunity

3verest is an equal‑opportunity employer. We welcome applicants of every background and are happy to make reasonable adjustments throughout the process.
