Job Description:

• We are seeking a highly skilled Senior Security Test Automation Engineer with deep expertise in the integration and inner workings of Hardware Security Modules (HSMs) and Key Management Systems (KMS) to design build test and validate enterprise-grade cryptographic solutions using a custom test harness. This role focuses on end-to-end validation after automated patch deployment on critical cryptographic platforms.
• Key Responsibilities
• Engineering Architecture
• Design deploy and manage HSM and KMS platforms across on-prem and cloud environments
• Develop and integrate secure cryptographic services leveraging REST-based APIs
• Interface with enterprise security architecture to ensure alignment with cryptographic standards and policies
• Support automated patch validation and continuous platform currency lifecycle management across cryptographic infrastructure
• Development Automation
• Build and maintain CRUD-based REST APIs using Python and Java
• Develop automation solutions using Ansible and shell scripting for provisioning patching and testing
• Create reusable frameworks for platform validation and operational efficiency
• Integrate automation into CI/CD pipelines for consistent validation and deployments
• Testing Validation
• Design and implement end-to-end automated test harnesses for validation of:
• Patches and upgrades
• Security controls and configurations
• Functional and performance requirements
• Develop detailed test cases and scenarios for cryptographic workflows and integrations
• Execute regression functional and performance testing across environments
• Documentation Troubleshooting
• Produce comprehensive documentation including:
• Test scenarios and validation results
• Failure analysis and root cause findings
• Step-by-step troubleshooting and recovery procedures
• Maintain operational runbooks and knowledge base artifacts
• Lead troubleshooting efforts for complex issues across HSM/KMS platforms
• Collaboration Communication
• Clearly articulate technical concepts to cross-functional teams

• Linux environments and shell scripting
• Configuration management tools using Ansible
• Hands-on experience in:
• Automated testing frameworks and test harness design
• Patch validation and end-to-end system testing
• Exposure to DevOps and CI/CD practices
• Experience in performance testing and security validation at scale
• Strong problem-solving and analytical skills
• Excellent verbal and written communication skills
• Preferred Qualifications
• Experience with HSM/KMS vendors such as Thales Utimaco FutureX or Entrust
• Familiarity with cloud KMS offerings (e.g. AWS KMS Azure Key Vault)
• Knowledge of security frameworks (NIST ISO 27001 PCI DSS)
• Cryptographic principles PKI and security protocols (e.g. TLS SSH)

Key Competencies

• Strong documentation and structured thinking
• Attention to detail in testing validation and troubleshooting
• Capability to communicate complex security concepts clearly
