P1 Security is a leading company in mobile network security, providing solutions to defend against network cybersecurity threats and attacks. Founded in 2009, the company specializes in securing telecom protocols and offers products and services like intrusion detection systems, vulnerability scanning, and threat management. P1 Security assists operators, governments, and enterprises in securing their mobile infrastructure, particularly focusing on technologies from 2G to 5G.

📋 Description

• Lead and deliver deep‑dive telecom security risk assessments and security consulting for operators, vendors, and critical infrastructure programs (Security Architecture Reviews, RAN & OSS Risk Assessment, MOCN Risk Assessment, IMS Cloud Risk Assessment, 5G Core Risk Assessment). • Define assessment scope, threat model, and risk methodology; translate technical findings into clear, actionable risk statements and remediation roadmaps. • Perform architecture and design reviews across 2G/3G/4G/5G, IMS, EPC/5GC, RAN/OpenRAN, OSS/BSS, interconnect, roaming, cloud-native telecom platforms (Kubernetes/OpenStack), wireline and other OT and IT infrastructure. • Assess security controls and compliance alignment (e.g., GSMA, 3GPP, NIST/ISO principles) including identity, key management, crypto choices, secure boot, supply chain, and operational security. • Analyze protocol and interface exposure (SS7, Diameter, GTP, SIP/IMS, SIGTRAN, HTTP APIs) and identify abuse cases, misconfigurations, and systemic weaknesses. • Evaluate cloud and platform security for telecom workloads (multi-tenancy, network segmentation, service mesh, IAM, secrets management, CI/CD, container hardening). • Conduct evidence-based testing and validation when required (configuration review, log review, traffic analysis, fuzzing/abuse-case testing) and coordinate with P1 Labs R&D for advanced topics. • Produce high-quality deliverables: executive summaries, technical annexes, risk registers, reports and presentations; ensure consistency and repeatability across engagements. • Support pre-sales and customer workshops: clarify requirements, estimate effort, contribute to proposals, and communicate scope and value. • Mentor team members and contribute to internal knowledge base, assessment playbooks, and reusable tooling.

🎯 Requirements

• 5+ years of experience in telecom security, network security, or risk assessment/consulting for telecom operators, infrastructure providers, or security vendors. • Experience working in consulting and/or client-facing delivery, with a strong focus on clear communication and stakeholder management. • Demonstrated ability to perform security architecture reviews and turn complex technical issues into prioritized, business-relevant risks and mitigations. • Hands-on security knowledge across at least two of the following: protocol security, cloud/Kubernetes security, Linux hardening, IAM/PKI/key management, vulnerability research, incident response, or SOC/monitoring. • Familiarity with telecom and security standards and guidance (e.g., 3GPP security, GSMA FS/NG, NIST, ISO 27001/27002). • Certifications are a plus but not required. • Experience working with AI-assisted delivery with privacy in mind (e.g., LLM tools) and strong judgment to decide AI applicability and to review, validate, and challenge AI-generated content; able to ensure accuracy, completeness, and appropriate confidentiality. • Comfortable working with technical artifacts: network diagrams, HLD/LLD, configuration baselines, cloud manifests, logs, PCAPs; able to validate evidence and challenge assumptions. • Strong written and verbal communication skills; ability to write structured reports and present to both technical and executive stakeholders. • Ability to work autonomously in a client-facing environment, manage priorities, and deliver on time across multiple engagements.

🏖️ Benefits

• Flexible remote work with periodic meetups for collaboration and team bonding
