At Luxquanta, we are pioneering the Quantum Communications industry, delivering solutions that use the properties of quantum physics to secure communications. Five years in, we're scaling internationally — and we're looking for a technical leader who wants to own the IT infrastructure of a deep-tech company handling truly sensitive, classified information from day one.
As IT System Manager, you'll have full ownership of Luxquanta's internal IT infrastructure — from cloud environments to air-gapped networks. In a company where IT security and system availability are regulatory requirements, not just operational nice-to-haves, this role carries real technical authority and direct influence over how we scale securely.
Infrastructure & Operations: Deploy, maintain and monitor servers, network and endpoint infrastructure, manage our Microsoft Azure environment, and lead backup and disaster recovery planning and testing.
End-User Support & Device Management: Be the technical backbone for all employees — manage MDM, own IT onboarding/offboarding end-to-end, and deliver IT inductions for new hires.




Network Administration: Design and monitor our LAN/WAN/wireless infrastructure, manage VLANs and firewall segmentation, and maintain isolated networks for classified information.
Compliance & Governance: Keep IT documentation and security policies current, support ENS/GDPR audits, and report regularly on infrastructure status and risk.
Degree in Computer Science, IT, or Telecommunications
~3–5 years of hands-on experience in IT systems administration or infrastructure, ideally in a fast-paced or regulated environment
~ Spanish & English: professional working proficiency
~ Cybersecurity certification (CISM, CISSP, ISO 27001 Lead Implementer) — strong plus
~ Familiarity with Zero Trust, CIS Controls or NIST — a plus

Competitive salary + private health insurance + ticket guardería
Hybrid working model with adaptable hours
Short Fridays during the summer
Subsidized lunch at the office (under €2!)
