Cybersecurity Architect

Date: 29 Oct 2025

Company: Alstom

At Alstom, we understand transport networks and what moves people. From high-speed trains, metros, monorails, and trams, to turnkey systems, services, infrastructure, signalling and digital mobility, we offer our diverse customers the broadest portfolio in the industry. Every day, more than 80 000 colleagues lead the way to greener and smarter mobility worldwide, connecting cities as we reduce carbon and replace cars.

Could you be the Cybersecurity Architect we are looking for?
Reporting to the Head of Cybersecurity for Customer & Industrial IT, you will ensure the security of new digital solutions provided by Alstom to its clients following the SaaS model.

We will look to you to:

• Analyze solutions, identify associated risks, and propose security architecture models by involving various cybersecurity experts (network, IAM, SIEM, SOC, etc.) and applying the cybersecurity models approved by Alstom. You will assess deviations from security policies to grant or deny exemptions based on the risk level and the associated remediation plan.
• Ensure the implementation follow-up of security solutions for these new offerings, collaborating with cybersecurity, infrastructure, and business application teams.
• Participate in defining secure architecture models, cybersecurity policies, and the cybersecurity roadmap.

We value passion and attitude over experience. That’s why we don’t expect you to have every single skill. Instead, we’ve listed some that we think will help you succeed and grow in this role:

• You hold an engineering degree or equivalent, preferably in information technology, with at least 4 years of relevant experience in cybersecurity architecture and overall experience of around 10 years.
• A general understanding of cybersecurity principles, processes, and solutions.
• Ability to define a cybersecurity plan and strategy for our solutions.
• Capacity to analyze technical risks and vulnerabilities.
• Knowledge of ISO 27002 and ISO 27005 standards.
• Familiarity with the ISA/IEC 62443 standard; certification is a plus.
• Understanding of OT environments.
• Ability to navigate a complex organizational, technical, and business environment.
• Strong communication skills, efficiency, and execution capability. Results-oriented with intellectual curiosity and creativity. An innovative and tactical mindset ready to contribute to strategic topics.
• You are fluent in English and have a desire to work independently in an international environment.

You don’t need to be a train enthusiast to thrive with us. We guarantee that when you step onto one of our trains with your friends or family, you’ll be proud. If you’re up for the challenge, we’d love to hear from you!

Additionally, in the face of environmental challenges, many employees are choosing to cycle for their commute. To support this approach, the Saint-Ouen site has suitable infrastructure (secure parking, maintenance and inflation stations, lockers, etc.).

Important to note

As a global business, we’re an equal-opportunity employer that celebrates diversity across the 63 countries we operate in. We’re committed to creating an inclusive workplace for everyone.
