This role is pivotal to the success of the project and requires a proactive, fast-learning individual who can combine deep technical expertise in C++ with strong collaboration skills to bridge legacy and modern architectures. Your Impact: Perform reverse engineering of legacy C++ applications to understand architecture, business logic, and database interactions. Analyze and document existing PostgreSQL integration logic and lead the creation of a new connection component for a modern relational database. Collaborate with the Java team to ensure accurate translation of C++ functionality into Java as part of the migration effort. Develop, maintain, and optimize high-performance C++ code during the transition phase. Troubleshoot and resolve technical issues in C++/PostgreSQL integration and migration-related workflows. Contribute to architectural discussions, design reviews, and technical planning sessions. Prepare documentation to support knowledge transfer across teams. Qualifications Your Skills and Experience Proven experience in C++ development (7+ years preferred). Strong background in reverse engineering and modernization of legacy systems. Hands-on experience with PostgreSQL or other relational databases, including query optimization, indexing, and performance tuning. Familiarity with PostgreSQL C++ libraries (e.g., libpqxx) or willingness to quickly ramp up. Strong understanding of object-oriented programming, memory management, and multithreading in C++. Experience working in Linux-based development environments. Excellent problem-solving and analytical skills, with the ability to adapt in complex migration projects. Strong communication and collaboration abilities to work effectively with cross-functional teams. Set Yourself Apart With Prior experience in migration projects (especially C++ to Java or legacy to modern stacks). Knowledge of Java - desirable but not required. Experience designing database connectivity layers or middleware components. Exposure to AI-driven platforms or large-scale distributed systems.
