Senior IT Site Technician & Endpoint Security Engineer, London

8x8 connects our customers and teams globally, empowering CX leaders with performance and insights to make smarter decisions, delight customers, and drive lasting business impact. At 8x8 we're reimagining how work gets done, and AI is at the centre of that. We're looking for a Senior IT Site Technician & Endpoint Security Engineer to be the full-time on-site technical heartbeat of our London office — and the global engineering owner of the endpoint security stack that protects every 8x8 employee.

This is a hands-on local IT support role with a serious global engineering dimension. Your time will be split roughly evenly between two focuses:

• London Site IT Support (primary presence): You are the walk-up face of IT in London. You handle day-to-day device support, provisioning, AV, asset management, and ensuring the office just works.
• Endpoint Security Engineering (global scope): You are the SME and service owner for MDM, Zero Trust access, work app isolation, DLP, and endpoint hardening across the enterprise. You own the strategy, processes, and Tier 3/4 support for these services.

If you thrive on being the person colleagues turn to when something breaks — and you want that hands-on role to sit alongside serious global security engineering responsibility — this was written for you.

What You'll Do

London Site Support (Your Day-to-Day)

• Be the walk-up and desk-side support for London office employees — calm, fast, and thorough.
• Own device provisioning: new-hire builds, onboarding training, laptop refresh, and secure device retirement.
• Own AV and meeting-room technology: daily checks, troubleshooting, and keeping rooms ready for business.
• Own local asset management: receiving, tagging, stock control, and end-of-life disposal in line with policy.
• Deliver on-site technical support for events and executive visits.
• Coordinate with other Site Technical Leads on site coverage, escalations, and cross-office standards.

Endpoint Security Engineering (Global)

Your mission: Research, select, deploy, and operationalize the tooling that carries 8x8 forward across MDM, work app isolation, Zero Trust access, DLP, and device hardening.

• Own MDM strategy and configuration across MacOS, Windows, iOS, and Android. Includes compliance baselines, hardening, and self-service app delivery across 1,000+ devices.
• Own the work app isolation and BYOD data-containment model — evaluate, select, deploy, and support the chosen platform.
• Own the ZTNA client rollout and endpoint compliance posture as a real gate for network access.
• Own endpoint security policy: DLP, patching cadence, OS hardening, application control, USB and removable media controls.
• Own laptop backup coverage, policy, and periodic recovery testing.
• Partner with 8x8's Security team on EDR/XDR endpoint tuning and incident triage.
• Produce SOC 2 and ISO 27001 evidence for endpoint controls during audit cycles.

AI-Augmented Way of Working

• Use 8x8's approved AI tools (Google Gemini, Claude, AI Studio) to work faster — from policy docs to script drafting to telemetry analysis.
• Spot AI-driven automation opportunities across endpoint and site operations.
• Help colleagues build their own AI fluency.

What We're Looking For

Required

• Bachelor's degree in Computer Science, Information Technology, or related field, or equivalent hands-on experience.
• Minimum 6 years' experience in endpoint engineering or endpoint security, with clear senior-level ownership in recent roles.
• Hands-on MDM experience at scale (1,000+ devices) using Addigy, Jamf, Intune, or equivalent.
• Endpoint security policy design experience across DLP, patching, OS hardening, and application control.
• Working knowledge of EDR/XDR platforms (CrowdStrike, SentinelOne, or Microsoft Defender for Endpoint), including deployment, tuning, and incident triage.
• Working knowledge of ZTNA and Zero Trust access — you can explain the endpoint-to-identity policy chain in plain terms.
• Customer service instinct. You're the person a stressed colleague walks up to. You triage calmly, solve what you can, and route what you can't.
• Genuine openness and enthusiasm for AI tools. We will grow you into our AI-first approach; you bring the curiosity.
• Ability to work independently, take initiative, and be effective with or without detailed direction.
• Ability to lift and move equipment weighing up to 20 kg (approx. 45 lb) around the London office.

Preferred

• Corporate AV and meeting-room experience (Zoom Rooms, Google Meet Series One, Poly, Logitech) — AV troubleshooting is usually a cable, not a mystery.
• Hands-on experience with work app isolation or BYOD platforms (Venn Blue Border, Ivanti / MobileIron, or comparable).
• Familiarity with Okta and Microsoft Entra ID for conditional access partnership.
• Prior experience producing SOC 2 or ISO 27001 evidence for endpoint controls.
• Experience with laptop backup platforms (Druva or comparable) and recovery testing.

Why 8x8?

We're a Silicon Valley-founded, Nasdaq-listed company powering customer experience for organisations around the world — with an increasingly AI-native approach. Internal IT at 8x8 isn't a back-office function. We shape how the business operates, experiment with technology, and lead from the front.

You will be the visible, trusted face of IT in London — and simultaneously influence the endpoint security posture of every 8x8 employee globally. If hands-on site support energises you and global security engineering is your craft, we'd love to hear from you.

8x8 believes diversity makes our company stronger which is why we are a proud equal opportunities employer and encourage all of our staff to bring their authentic selves to work. We believe in fairness which is why we have been a member of the Living Wage Foundation for many years and we believe in security so reserve the right to undertake background checks on anyone that we extend an employment offer to.
