ASN Tech Stack

Submarine cable systems and turnkey undersea transmission infrastructure

Telecommunications Les Ulis, Ile-de-France 1,001–5,000 employees Founded 1994 Privately Held

ASN designs and deploys submarine optical networks, with over 850,000 km of systems installed globally. The tech stack reflects a mature industrial operations footprint—SAP core (ECC, Concur, PM), Oracle and Vertica for data, Tableau for reporting—paired with active migration toward identity and security infrastructure (Active Directory Federation Services, IAM, SIEM, Firewall adoption). The project mix signals internal modernization: treasury system evolution, front-office optimization, and vulnerability management run alongside core R&D and integration work, while hiring velocity is decelerating across engineering and finance roles.
