ABOUT THE JOB

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.

• Own the Anduril radio Approved Products List (APL); ensure all hardware and software meet Trade Agreements Act (TAA) and NDAA Section 889 requirements. Hytera, Huawei, and ZTE radio products are categorically excluded under Section 889 (b)(1) and the FCC Covered List.
• Design intercom systems for facility entrances, dock doors, controlled access points, and accessible entries, using SIP-native platforms such as Aiphone IX, 2N, Commend, or Zenitel/Stentofon, integrated with Security Center.
• Architect and deploy emergency call (blue light) systems using platforms such as Code Blue.
• Architect and deploy enterprise mass notification, with delivery across radios, IP phones, IP speakers, mobile applications, desktop pop-ups, and digital signage. Develop notification policy and routing logic.
• Engineer IP paging, public address, and overhead speaker systems using SIP-native or SIP-bridged endpoints.
• Engineer the network underlay required by voice and SIP services, including QoS marking and queueing for RTP, multicast routing for IP paging, VLAN segmentation, PoE budgeting, and switch port profiles.
• Coordinate with IT and InfoSec on SIP signaling security (TLS), media encryption (SRTP), session border control, perimeter design, and lawful logging of communications events into the enterprise SIEM.
• Design and operate the dispatch console architecture for the GSOC, integrating LMR, LTE PTT, SIP intercom, and mass notification under a unified operator experience using Genetec Mission Control SOPs.
• Maintain interface documentation and network diagrams for every site, including donor antenna locations, BDA placement, head-end distribution, and SBC connectivity.

REQUIRED QUALIFICATIONS

• Bachelor’s degree in Electrical Engineering, Communications Engineering, Computer Science, Information Technology, or a related technical field, or equivalent practical experience.
• Hands-on SIP architecture and operations: SIP, SDP, RTP, SRTP, TLS for SIP signaling, codec selection, dial plan design, and Session Border Controller configuration.
• Direct experience integrating SIP intercom platforms with a video management or access control system, ideally Genetec Sipelia integrated with Security Center, or equivalent integrations such as Aiphone IX or Zenitel/Stentofon.
• Exceptional problem-solving abilities and keen attention to detail.
• Excellent communication skills and the ability to effectively engage with stakeholders at all levels, including senior leadership and construction teams.
• Adept at working in a fast-paced environment and making sound decisions in challenging situations.
