About the job Senior C++ Developer

We are looking for a Senior C++ Engineer with strong low-level programming and security expertise to identify and remediate vulnerabilities in a large-scale, mature healthcare product. The ideal candidate has hands-on experience with legacy C++ codebases, memory safety (pointers, buffer overflows, memory corruption), multithreading, secure coding, and strong debugging/troubleshooting skills.

About the role

In this role, you will improve the security and resilience of a large-scale healthcare product used in enterprise environments. Working within an extended security engineering team, you will help identify, analyze, and remediate vulnerabilities across a mature C++ application while collaborating closely with architects, QA engineers, security specialists, and experienced product developers.

Your work will directly contribute to reducing technical risk and strengthening secure software development practices.

Conditions

• Location - Bulgaria, Poland (remote)
• B2B contract ( rate 30 -38 USD /h)

Responsibilities

• Analyze assigned security requirements and security findings
• Implement security-related changes in the healthcare product
• Remediate vulnerabilities such as unsafe input and length handling, buffer-overflow or memory-corruption risks, and SQL injection
• Work safely with a large legacy C++ codebase, including pointer-based and memory-sensitive logic
• Maintain and improve existing threading components
• Identify technical impact and regression risks before modifying existing functionality
• Participate in code reviews, testing, debugging, and troubleshooting
• Continuously integrate changes into the existing product and collaborate closely with the client's developers and architects

Requirements

• Strong commercial experience with C++, including mature or legacy C++ codebases
• Advanced knowledge of low-level programming, including pointers, pointer arithmetic, manual memory management, bounds checking, and memory safety
• Proven experience identifying and remediating native-code vulnerabilities such as buffer overflows, memory corruption issues, and unsafe input handling
• Practical experience working with multithreaded applications and thread-safe development approaches
• Strong understanding of object-oriented programming principles and software design concepts
• Familiarity with Qt or other desktop UI frameworks is an advantage
• Experience developing Windows or Windows Server-based enterprise applications is an advantage
• Good knowledge of SQL and secure database interaction principles; Oracle Database experience is a plus
• Exposure to ISAM or other legacy data-storage technologies is beneficial
• Well-developed debugging, troubleshooting, and analytical problem-solving skills
• Experience with secure software development and remediation of documented security findings is strongly preferred
• Proficiency in close collaboration with architects, QA engineers, security experts, and existing product developers
