Welcome! Super excited you dropped by 🥳

✨The core mission of the Senior IT Platform engineer

As an Internal Platform Engineer, you will own and evolve the internal tooling and enterprise platforms that keep a 300+ person, globally distributed company running securely and productively.

This is not a helpdesk role — you'll be the engineering backbone behind identity & access management, corporate email and collaboration, device management, SaaS orchestration and our centralised AI/LLM gateway. You'll ensure that every team at HTB has the right tools, properly integrated, secured and automated.

Engineer, integrate and operate HTB's internal platform stack — from identity (Okta) and email (Google Workspace) through endpoint management (Jamf/Intune) and security tooling (SIEM, EDR) to our centralised LLM gateway — so that the company scales securely without friction.
