Job description

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.

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
