We are looking for an experienced C++ Engineer to lead the modernization of a legacy C++ application into a modular, maintainable, and scalable product. This role is unique in its integration of Generative AI.
You will partner with a GenAI engineering team to reverse-engineer complex codebases and define strategies for forward-engineering into modern languages.
Responsibilities
Partner with GenAI teams to trace execution paths, uncover implicit behaviors, and identify side effects within large legacy monoliths.Build comprehensive system documentation, including component diagrams, sequence flows, dependency maps, and API contracts derived from existing code.Define the target architecture and migration phases, using patterns such as the Strangler Fig Pattern for incremental re-platforming.Create and refine LLM prompts and retrieval contexts to accelerate code understanding, while validating GenAI outputs to ensure functional parity.Convert legacy C++ constructs (memory handling, concurrency, state management) into modern equivalents in the target language.Identify hidden dependencies and concurrency hazards. Ensure the new system meets SLAs for performance, security, and observability.Drive characterization testing and build regression suites and "golden datasets" to verify behavior during migration.
Required Experience
5+ years of experience with C++, including Modern C++ (C++11/14/17; C++20 preferred).Proven track record of modernizing large, tightly-coupled codebases.Strong mastery of OOP, SOLID principles, and clean architecture.Advanced skills using gdb, lldb, or Visual Studio debugger for crash analysis and core dumps.Proficiency with CMake is strongly preferred.Firm grasp of data structures, algorithms, and performance optimization.
