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.

About the Role

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.

Main Tasks & Responsibilities

- 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. xqbhyrx
- Degree in Computer Science, IT, or Telecommunications

- Spanish & English: professional working proficiency

- Experience with regulatory frameworks such as ENS, ISO 27001 or GDPR - strong plus
- Familiarity with Zero Trust, CIS Controls or NIST - a plus
