Senior IT Site Technician & Endpoint Security Engineer, London

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.
