Unix Developer

This is a remote position.

We are looking for a skilled Unix Developer with 5–8 years of experience in C++ application development and UNIX Shell scripting. The ideal candidate should have hands-on experience developing high-performance applications on UNIX platforms and possess a strong understanding of encryption technologies and Hardware Security Modules (HSMs). Experience with secure application development and cryptographic key management is highly desirable.

• Design, develop, test, and maintain robust, scalable, and high-performance C++ applications for UNIX-based environments.
  
• Write, optimize, and maintain UNIX Shell scripts (Bash, Korn Shell, or POSIX Shell) for automation, batch processing, system monitoring, and operational support.
  
• 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.
  

• 5–8 years of experience in UNIX application development.
  
• Strong programming experience in C++.
  
• Excellent knowledge of UNIX/Linux operating systems.
  
• Hands-on experience with UNIX Shell Scripting (Bash, Korn Shell, or POSIX Shell).
  
• Strong understanding of system programming concepts and UNIX internals.
  
• Experience in debugging, performance optimization, and memory management.
  
• Good knowledge of encryption concepts, cryptographic algorithms, and secure application development.
  
• Experience integrating and managing Hardware Security Modules (HSMs).
  
• Familiarity with PKCS#11, Microsoft CNG, OpenSSL, or similar cryptographic frameworks.
  
• Experience with version control tools such as Git.
