Responsibilities:

• Analyze network designs and existing system 5G Private Wireless Radio Access Network (RAN) deployments to identify potential vulnerabilities and recommend remediation efforts
• Proactively identify opportunities to improve system security controls, enhance threat detection and reduce attack surfaces during all phases of the system development lifecycle (SDLC)
• Assist in the architecture and design of ORAN WG11 security countermeasures to protect control plane, user plane, and management plane traffic
• Ensure JMA RAN solutions comply with ORAN Working Group 11 (WG 11) security specifications, which cover cryptographic methods, authentication, integrity protection, and authorization mechanisms specific to the O-RAN architecture​.
• Spearhead POC (Proof of Concept) activities and participate in decision making for new product analysis and selection
• Create and document hardening profiles for third-party network products to include switches, routers, precision network time servers, VPN appliances, and IPSec tunnels
• Conduct threat modeling and risk assessments in alignment with O-RAN WG11's Security Control Framework and 3GPP TS 33.501 and TS 33.117 risk mitigation strategies.
• Develop test cases based on the O-RAN Security Test Specifications and ensure comprehensive security testing.
• Collaborate with the RAN Systems team to validate the security architecture in O-RAN deployments through end-to-end testing​.
• Collaborate with cross-functional teams to integrate security controls​.
• Stay updated on the latest developments in O-RAN WG11 security protocols and 3GPP standards to ensure future-proof security designs​.
• Stay updated on training and certifications
• Able to multi-task and pivot based on business needs.
• Able to convey, document, and communicate technical information for a wide array of audiences
• Can work with an engaged, independent mindset.
