Analyze, troubleshoot, and resolve application and system issues in UNIX environments.
Develop reusable, efficient, and reliable code following coding standards and best practices.
Implement secure coding practices to protect sensitive data at rest and in transit.
Integrate and manage Hardware Security Modules (HSMs) such as Thales, SafeNet, or Utimaco for secure cryptographic operations.
Configure and interface with HSMs using standard APIs such as PKCS#11, Microsoft CNG, or vendor-specific APIs.
Implement cryptographic functions including encryption, decryption, digital signatures, certificate management, and secure key lifecycle management.
Collaborate with cross-functional teams to understand business requirements and deliver secure, high-quality solutions.
Participate in code reviews, performance tuning, debugging, and production support.
