IT Admin & Support

We are looking for an IT Admin & Support to handle both day-to-day user support (N1/N2/N3 helpdesk) and the administration of the company's IT infrastructure. This hybrid role — split equally between helpdesk and systems administration — is critical in a demanding space systems environment. You will be the go-to IT contact for all internal teams, while actively contributing to the availability, performance, and security of our infrastructure. Job Description 1.

• Resolve N2 tickets: advanced diagnostics, network troubleshooting, configuration issues, and access rights management.
• Escalate to N3 for complex issues involving servers, virtualization, or network equipment.
• Manage and prioritize tickets using an ITSM tool (creation, tracking, resolution, closure, reporting).
• Handle user onboarding and offboarding: provisioning and revoking access (AD, email, VPN, business applications).
• Deploy and configure workstations (images, software, peripherals) on both Windows and Linux environments.
• Run internal training sessions and awareness programs on IT best practices and cybersecurity.

2. Systems and Network Administration

• Administer and maintain Windows and Linux servers, user workstations, and associated services (file sharing, backups, antivirus, Active Directory).
• Manage local and cloud infrastructure (Microsoft 365, Google Cloud, or equivalent).
• Administer network infrastructure: switches, firewalls, VPNs, Wi-Fi, VLANs, routing.
• Monitor system performance, availability, and usage; plan upgrades and capacity expansion.
• Maintain IT asset inventory and manage the hardware/software lifecycle.
• Manage virtualization environments (VMware, Proxmox) and backup solutions.

3. Documentation and Continuous Improvement

• Draft and maintain IT procedures, user guides, and technical documentation.
• Contribute to the helpdesk knowledge base (FAQs, resolution guides, tutorials).
• Propose improvements to tools, processes, and service levels (SLA/OLA).

What we offer

• The opportunity to be part of an international team transforming the space industry.
• A creative and innovative work environment where ideas turn into reality.
