The Technical Security (Tech Sec) team within Anduril's Corporate Security Program is dedicated to protecting our people, physical assets, and proprietary innovations. We design, procure, and deploy robust technical security infrastructure and systems across our global footprint. Our mission is to create a secure built environment that enables Anduril's transformative work in defense technology. We focus on anticipating and addressing technical security challenges, ensuring Anduril's continued growth and innovation in a complex global landscape.

The Security Communications Systems Architect is the technical authority for Anduril’s national radio system and the constellation of voice, intercom, emergency call, and mass notification systems that constitute the security communications environment. Reporting to the Senior Manager, Technical Security Systems Architecture, this role is a senior individual contributor position responsible for the architecture, deployment, and ongoing operation of Land Mobile Radio (LMR), broadband Push-to-Talk (PTT), SIP‑based intercom and code blue systems, public safety in‑building radio coverage, and enterprise mass notification.

The successful candidate is fluent on both sides of the radio‑to‑IP boundary: comfortable engineering a radio fleet and an FCC Part 90 license application as well as SIP trunking, an SBC dial plan, IP networking, and a Genetec Sipelia integration. Your expertise will be critical in designing, building, procuring, maintaining, and continually enhancing our technical security systems and programs to protect company assets and personnel.
