Posting Start Date: 10 Feb 2026

Location: Toulouse, FR

Company: Serco Plc

Introduction

Serco is a leading Space Services Provider with thousands of skilled resources that has supported over 50 space missions on behalf of more than 10 Space or Government agencies around the globe, including the ESA and NASA. Serco offers space capability across the full space lifecycle from satellite testing to Launch services, LEOP to spacecraft operations, space surveillance to data management, and supporting downstream application development.

With this in mind, we are seeking a European-based Cyber Security Manager that will be responsible for leading cybersecurity activities for a key customer within the European Space division. 

Your Mission

You will contribute to cybersecurity coordination activities for one of the key elements of the Galileo program to meet our customers’ requirements, leading to successful outcomes.

You will have the opportunity to lead and coordinate cybersecurity operations for one of the services managing activities for the European GNSS Service Center (GSC), which provides a centre of expertise, knowledge sharing, custom performance assessment, information dissemination and support to the provision of value-added services enabled by the Galileo OS, HAS and SAS core services.

What You'll Do

Lead the cybersecurity mission end‑to‑end. You will build and manage the cybersecurity organisation, acting as the primary interface for all security matters and ensuring everything we do aligns with our contractual and regulatory obligations.

Compliance is your daily rhythm. You maintain full, audit‑ready documentation, control deviations and waivers, and make sure every piece of required security evidence is captured, maintained, and easily defensible.

You take ownership of people and culture. You design and run the cybersecurity awareness programme, embed requirements into training plans, and ensure every person working on our systems has the right skills, certifications, and clearances to operate securely and effectively.

You keep our cybersecurity tools mission‑ready—fully updated, licensed, accessible, and capable of supporting real‑time monitoring, detection, and protection across the whole estate.

You maintain a continuously accurate network map that feeds directly into cybersecurity impact analyses whenever configurations change, ensuring nothing in our environment evolves without proper scrutiny.

Vulnerability management is one of your sharpest disciplines. You own the vulnerability database, monitor and classify new vulnerabilities, analyse associated risks, define mitigation actions, and coordinate the entire patching lifecycle—from validation and testing to deployment and, where necessary, waivers.

When a security event occurs, you are the one who brings order to the chaos. You support event handling from the first alert through containment, eradication, and recovery. You oversee system sanitization, log extraction, and cross‑team coordination to ensure clarity, speed, and accuracy.

You design, maintain, and enforce our full suite of preventive, detective, and recovery controls. You develop Lockdown Reports, drive system hardening, and ensure our operational environments remain secure and resilient throughout their lifecycle.

And you turn all this work into strategic value. You provide every cyber‑related input for monthly and quarterly reporting, vulnerability summaries, incident documentation, and accreditation evidence. You drive continuous improvement and embed lessons learned to strengthen the organisation with every cycle.

What You'll Bring

  • Ability to lead and operate a cybersecurity governance framework across a multi‑stakeholder environment.
  • Experience supporting full incident‑response cycles, including forensics, containment, eradication, and recovery coordination
  • Hands‑on proficiency with cybersecurity toolsets for monitoring, detection, analysis, and protective functions, including tool maintenance and access control.

  • ⁠Methodical, process-driven and organized approach with excellent attention to detail;

  • Certifications such as Security+, ISC2 Certified Cybersecurity, CCNA Security, or cloud security certifications (Azure or AWS)
  • Work experience in the Space domain will be an asset
  • Post-graduate degree in Information Systems Security (or similar) will be an asset

  • Methodical and proactive, with initiative and capability to work autonomously
