Job type: Freelance contract (self employed)

Location: Paris (hybrid 6-8 days peer month onsite)

Duration: 12 months (scope for extension)


Role Overview

We are seeking an experienced Security Analyst to support a banking organisation in Belgium on a full-time freelance basis. This role requires a hands-on security professional who is comfortable independently conducting risk assessments and threat assessments, translating findings into actionable security improvements, and working closely with technology and business stakeholders.

This is not a purely advisory or oversight role — the successful candidate will be expected to personally perform assessments, analyse systems and processes in depth, and contribute directly to strengthening the bank’s security posture.


Key Responsibilities

  • Conduct hands-on security risk assessments across applications, infrastructure, cloud environments, and business processes.
  • Perform threat assessments and threat modelling, identifying attack vectors, vulnerabilities, and potential business impacts.
  • Analyse security risks related to financial systems, sensitive data, and regulated banking environments.
  • Document findings clearly, including risk ratings, threat scenarios, and practical mitigation recommendations.
  • Work closely with engineering, infrastructure, cloud, and business teams to validate risks and agree on remediation actions.
  • Support security reviews of new initiatives, system changes, and third-party integrations.
  • Contribute to improving security standards, controls, and assessment methodologies within the organisation.
  • Ensure alignment with relevant banking regulations, internal security policies, and industry best practices.


Required Experience & Skills

  • Proven experience as a Security Analyst, Information Security Analyst, or similar role within banking or financial services.
  • Strong, demonstrable experience conducting risk assessments and threat assessments hands-on (not purely coordinating or reviewing others’ work).
  • Solid understanding of:
  • Information security principles (confidentiality, integrity, availability)
  • Threat modelling methodologies and risk frameworks
  • Common attack vectors and vulnerabilities in enterprise and cloud environments
  • Experience working in regulated environments, ideally within a bank or financial institution.
  • Ability to communicate complex security risks clearly to both technical and non-technical stakeholders.
  • Comfortable working autonomously as a freelance contractor in a fast-paced environment.


Nice to Have

  • Familiarity with financial regulations and standards (e.g. ISO 27001, NIST, EBA guidelines, PCI DSS).
  • Experience assessing cloud-based architectures (AWS, Azure, or GCP).
  • Background in application security, infrastructure security, or third-party risk.
  • Experience working in hybrid or multi-country European banking environments.
