Staff Cyber Security Engineer (AWS Cloud)

Partner closely with the existing Cloud Architecture and Engineering teams to audit the current AWS environment, identify security technical debt, and plan the refactoring of legacy resources into secure Terraform code.

• Design, deploy, tune, and maintain AWS WAF (Web Application Firewall) policies and rulesets to proactively protect corporate applications and APIs against application-layer attacks (OWASP Top 10, bots, and zero-day exploits).
• Establish and enforce cloud security guardrails, multi-account structures (AWS Organizations/Control Tower), and Service Control Policies (SCPs) in collaboration with the infrastructure team.
• Help on define and audit AWS Identity and Access Management (IAM) strategies, guiding engineering teams to transition from over-privileged legacy roles toward the principle of least privilege.
• Manage and optimize cloud-native security monitoring and detection tools (AWS Security Hub, Guard Duty, Cloud Trail, Inspector, or KMS).
• Help on the incident respond for AWS-specific security alerts, performing cloud forensic analysis and coordinating containment strategies.
• Ensure the AWS cloud ecosystem remains fully compliant with relevant financial regulations, internal policies, and security frameworks (NIST, CIS, Ba Fin requirements).
• Lead the security automatizations on the AWS environment.
• Understanding of AWS native AI capabilities (ie Bedrock or Quick).
