About P1 Security

Founded in 2011, P1 Security is on a mission to secure critical and sovereign mobile networks by providing services and technologies to identify, detect, and recover from critical threats and vulnerabilities.

We address telecom security challenges across 5G, cloud-based infrastructure, OpenRAN, network slicing, edge computing (MEC), and legacy telecom systems (2/3/4G), including Diameter, SS7, SIGTRAN, GTP, and related attack surfaces.

Our team includes telecom operators, security professionals, and researchers who regularly share cutting-edge work at international security conferences and GSMA working groups. P1 Labs, our R&D branch, also shares open-source initiatives with the telecom security community (GitHub).

About the Role

As a Telecom Signalling Security Analyst, you will combine customer-facing delivery with hands-on technical execution in sensitive telecom environments.

You will:

• Support and operate P1 Security solutions in production contexts (notably PTM and VKB).
• Conduct signalling security audits using proprietary tooling (notably PTA) and deliver rigorous, professional reports and presentations to customers.

This is a profile-focused role: we are looking for someone who can cover both audit delivery and operational support.

Our teams are remote-first, with a preference for candidates who can overlap working hours with Central European Time.

Key Responsibilities

• Customer delivery & communication
  • Act as a technical point of contact for customers: scoping, updates, and delivery.
  • Deliver presentations, training, and debrief sessions.
