- Engage with stakeholders to clearly communicate risks and remediation actions

- Knowledge of PCI-DSS and regulated environments
- Relevant industry certifications (e.g. OSCP, CREST, GIAC or similar) preferred
- Strong communication skills, with the ability to influence both technical and non-technical stakeholders
- Opportunity to operate as a trusted security advisor, not just a tester
- Hybrid role balancing hands-on technical work with strategic influence
