You handle device provisioning, AV, asset management, and general on-site support. If you like the idea of setting the endpoint security direction for a 2,000-person global company while also being the person a colleague can walk up to when their laptop won't behave, this role was written for you. What You' ll Do: Your mission: Research, select, deploy, and operationalize the tooling that will carry us forward across MDM, work app isolation, Zero Trust access, DLP, and device hardening.

You can explain the endpoint-to-identity policy chain in plain terms. • Genuine openness and enthusiasm for AI tools. We will grow you into our AI-first approach; you bring the curiosity. • 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. • The ability to work and think independently, take initiative, and be effective with or without detailed work direction. • Ability to lift and move equipment weighing up to 20 kg (approx. 45 lb) around the London office as part of provisioning, AV, and refresh work.
