C++ Software Engineer; AI modernization

C++ Software Engineer (AI modernization)

Join to apply for the C++ Software Engineer (AI modernization) role at McLaren Strategic Solutions (MSS).

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.

• 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.

• 5+ years of experience with C++, including Modern C++ (C++11/14/17; C++20 preferred).
• Proven track record of modernizing large, tightly-coupled code bases.
• 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.
• Strong grasp of data structures, algorithms, and performance optimization.
