IT Engineer

We're not looking for a "ticket resolver".

We're hiring a **true IT Engineer** who owns internal systems end-to-end, keeps everything running smoothly, and actively raises the bar on security, reliability, and user experience.

At Onoff, IT is not back-office support. It's **mission-critical infrastructure behind a fast-growing global telecom SaaS product**.

We move fast. We expect ownership. And we value engineers who don't wait to be told what to fix.

What You'll Be Doing
- -------------------

* **Own IT Operations**

Provide high-quality L1--L3 support across hardware, software, systems, and networks. Ensure employees can work without friction.

* **Manage Access \& Identity**

Handle IAM end-to-end: onboarding, offboarding, permissions, MFA, RBAC, and access security across systems.

* **Administer Core Tools**

Maintain and optimise Google Workspace, Microsoft 365, Jira, Confluence, Dashlane, and internal SaaS platforms.

* **Support Infrastructure \& Connectivity**

Troubleshoot VPN, network, Wi-Fi, and access issues. Ensure secure and reliable remote connectivity.

* **Manage Devices \& Assets**

Oversee full hardware lifecycle (laptops, phones, peripherals) and ensure clean inventory and provisioning processes.

* **Strengthen Security Posture**

Apply security best practices (MFA, MDM, phishing protection, audit logs, access control). Participate in security initiatives.

* **Improve Processes \& Vendor Management**

Maintain licenses, manage renewals, optimise costs, and continuously improve IT workflows and documentation.

* **Support \& Collaborate**

Work closely with all teams, deliver clear user support, and contribute to a culture of reliability and accountability.

What We're Looking For
- ---------------------

You're a strong fit if you:

* Have solid experience in **IT support / sysadmin / internal IT engineering**

* Know **IAM, Active Directory, Google Workspace, M365 deeply**

* Can troubleshoot **complex IT issues independently**

* Understand **networking basics (VPN, DNS, connectivity, Wi-Fi)**

* Are comfortable in **SaaS-heavy environments**

* Care about **security, structure, and reliability**

* Take ownership instead of escalating everything

* Communicate clearly with non-technical users

What Will Set You Apart
- ----------------------

* Experience with **MDM tools (e.g. Intune)**

* Exposure to **security operations or compliance practices**

* Scripting / automation (PowerShell, Bash, Python)

* Experience in **fast-scaling tech or SaaS companies**

* Strong documentation \& process improvement mindset

Why Onoff?
- ---------

**Real ownership** -- You don't just support systems, you improve them

**Modern stack** -- Google Workspace, M365, IAM, SaaS ecosystem, MDM

**International environment** -- fast-paced, distributed, product-driven teams

**Impact at scale** -- your work directly supports global operations

**Strong benefits** -- extra holidays, wellbeing days, private health insurance

**Flexible perks** -- travel budget / sports compensation

**Learning culture** -- continuous improvement is expected, not optional

#### If you're someone who doesn't just "support IT" but actually **builds, secures, and improves it every day**, we should talk.

Send your CV and let's build a more reliable, scalable IT foundation together!
