As a Senior Cyber Security Engineer, you will contribute to Ledger’s high ambitions in maintaining a five-star cyber security practice and standard, by designing, selecting, implementing and operating a wide variety of security toolsets across different environments, working closely with other tech teams. Autonomous and creative, you’ll join a small team and take ownership of your projects. This will be a challenging and rewarding position and a very technical and "hands-on" role. 


Your responsibilities :

• Design, select, test, configure, deploy, maintain, monitor and fine-tune security solutions (such as VAS, SIEM, EDR, IAM, WAF and ad-hoc tools) into the overall environment to prevent, detect and/or mitigate vulnerabilities and threats in collaboration with the other related teams and security experts.

• Develop automation to manage security tools and integrate security standards in workflows (Infrastructure-as-Code, SDLC…).

• Build and feed relevant KPIs, SLAs and reporting to meet business objectives.

• Provide deep technological expertise, guidance, recommendations and standards on security at different layers (networks, systems, Cloud, endpoints, applications…) in a hybrid environment (Cloud/Onsite).

• Ensure that business requirements are understood and adhered to as well as security risks and standards in new and existing infrastructure are properly understood and mitigated.

• Assist in response to due diligence and internal / external security audit requests. 


Requirements for the role : unless specified, all the listed below are mandatory

• In-depth hands-on experience (min. 5 years) in Cyber Security, ideally including incident response and mitigation.

• In-depth and hands-on expertise in deploying, configuring and maintaining at least two (preferably more) security solutions among IAM/SSO, vulnerability assessment, SIEM, EDR, WAF, DLP, firewalls, IDS…

• Knowledge in system, network, DB and Cloud admin (Linux, TCP/IP, PGSQL, AWS..).

• Knowledge in web application security and SSDLC (OWASP, Git, CI/CD…). Developer and/or pentesting skills would be a good differentiator.

• Experience in scripting languages (Python, Shell), automation tools (Terraform, Ansible).

• Experience on leading complex and cross-team projects, in a fast-paced environment.

• Knowledge in at least one (preferably more) standards  (ISO 27001, SOC2 and GDPR).

• Bachelor’s degree in information security or technology (certifications may be nice-to-have).
