IT & Security Administrator

Company Description:

Aistech Space is focused on generating affordable, recurrent, high resolution thermal imagery of the planet to provide a new perspective of Earth’s changing resources. The company is based in Barcelona and aims to revolutionize remote sensing for environmental monitoring and resource management.

What you will do:

Aistech Space needs a guardian for its digital and physical infrastructure. You will be the single point of ownership for our corporate cybersecurity landscape (Antivirus/EDR, VPN, Access Control) while ensuring our physical IT operations (Networks, Hardware, Lab Setups) run flawlessly.

In this role, you are expected to:

  • Lead Cybersecurity Operations: Lead the adoption, configuration, and daily administration of our security suite (Endpoint Security/EDR). You will define policies, monitor threats, and ensure compliance across all workstations.
  • Secure Remote Access: Manage the corporate VPN infrastructure to ensure secure, encrypted remote access for our engineering teams and manage user identity/access rights efficiently.
  • Enforce Security Posture: Implement and maintain best practices such as Disk Encryption, Patch Management, and Multi-Factor Authentication (MFA) to ensure our development environment is secure.
  • Manage Physical Network: Administer the HQ network infrastructure (Firewalls, Switches, Wi-Fi APs) to monitor for bottlenecks and prevent unauthorized access.
  • Manage Office Racks : Deploy and maintain servers room, choosing the right equipment depending on needs from other teams.
  • Oversee IT Assets: Manage the lifecycle of all IT hardware (Laptops, Desktops), handling procurement, provisioning (Windows/Linux), and maintenance.
  • Provide Tier 1-3 Support: Serve as the primary contact for internal IT issues, troubleshooting hardware and software problems to minimize downtime for the team.
  • Support Mission Critical Testing: Prepare and deploy the specific computing infrastructure ("Test Rigs") required for satellite testing campaigns, ensuring data integrity and reliable recording.
  • Guarantee Field Connectivity: Ensure that when our team travels to external labs, they have a secure tunnel (VPN) back to HQ and reliable internet access.
Who you are:

You are a SysAdmin with a SecOps mindset. You are capable of making high-level decisions about security tools while remaining practical enough to handle daily operations. You understand how to balance strict security policies with developer velocity, and you are just as willing to crawl under a desk to fix a cable as you are to configure a firewall rule.

Must:

  • 3+ years of experience in System Administration with a strong focus on Security Operations .
  • Security Stack Experience: Proven experience administering Enterprise Antivirus/EDR solutions (e.g., SentinelOne, Bitdefender, CrowdStrike) and VPNs (OpenVPN, WireGuard, Fortinet, Tailscale).
  • OS Mastery: Strong proficiency in Windows Administration and Linux (Ubuntu/Debian) environments.
  • Networking Expertise: Deep understanding of TCP/IP, VLANs, Firewalls, and DNS.
  • Local Datacenter Expertise : Experience designing and deploying racks, servers, storage and switches for the servers room.
  • Autonomy: Ability to take a high-level goal (e.g., "Secure our laptops") and execute the implementation from vendor selection to deployment without hand-holding.
  • Hands-on Hardware Skills: Comfort with assembling and troubleshooting computer hardware and managing physical connections.
  • Fluent in English.
Nice to have:
  • Certifications such as CompTIA Security+, CCNA, or similar.
  • Experience in an ISO 27001 certified environment or with general information security standards.
  • Scripting skills (Bash, Python, or PowerShell) for automation.
  • Experience in the Aerospace, Industrial, or Engineering sectors.
