• Assess authentication, authorization, and session management mechanisms in web and mobile applications. 

• Review cloud configurations and deployments (e.g., GCP, etc.) for compliance with best practices and internal security baselines. 

• Simulate attack scenarios to evaluate resilience of multi-tenant cloud services and identify weak points in integration layers. 

• Work with R&D to define secure deployment and monitoring controls for production environments. 

• Provide remediation guidance to development teams and verify fixes through structured retesting. 

• Support audits and certifications (e.g., CSTAR, ISO 27017, IEC 62443, CRA) with test evidence and reports. 

Required Skills & Experience 

• 4+ years of experience in application or cloud security testing, ideally in SaaS or industrial/energy environments. 

• Deep knowledge of OWASP Top 10, API Security Top 10, and modern cloud security risks. 

• Solid understanding of cloud platforms (e.g., GCP), including IAM, networking, and policy enforcement. 

• Ability to chain low-severity findings into meaningful attack paths
