C++ QA Lead - Remote
About the role
This role is a remote contractor position within a fast-growing AI Data Services company. The company delivers training data for major AI companies and foundation-model labs. As a C++ Quality Assurance Lead, you will oversee quality, consistency, and trainer performance across C++ AI training projects.
Responsibilities
Review AI-generated C++ code and trainer/QA work, evaluating output quality against project guidelines and providing precise written feedback.
Evaluate code for correctness, compile-time validity, runtime behavior, memory safety, performance, algorithmic reasoning, debugging accuracy, readability, maintainability, formatting, instruction-following, and adherence to project-specific rubrics.
Identify and report issues such as undefined behavior, memory leaks, dangling references, race conditions, inefficient algorithms, non-compilable code, hallucinated APIs, or incomplete explanations.
Lead or support remote teams of trainers, reviewers, engineers, coding mentors, or QAs, ensuring they follow expected quality standards.
Respond to questions around memory safety, compilation, templates, STL usage, concurrency, complexity, testing, and rubric interpretation.
Create and maintain C++ style guides, trackers, FAQs, examples, honeypots, calibration tasks, and onboarding materials.
Run onboarding/training calls covering project expectations, rubrics, and C++ quality standards.
Flag unsafe, non-compilable, misleading, inefficient, or non-production-ready C++ recommendations.
Identify recurring quality gaps and build scalable QA processes.
Requirements
Bachelor’s or Master’s degree in Computer Science, Software Engineering, Computer Engineering, or equivalent professional software engineering experience.
Strong grasp of English to follow guidelines and provide clear technical feedback.
3+ years of professional experience in C++ development, systems programming, performance engineering, embedded software, backend engineering, code review, QA, or technical mentoring.
Strong understanding of modern C++ standards, RAII, smart pointers, templates, STL containers/algorithms, object lifetime, move semantics, concurrency, exceptions, memory management, and build systems.
Familiarity with CMake, GCC/Clang/MSVC, GDB/LLDB, sanitizers, Valgrind, GoogleTest, Catch2, Boost, GitHub, CI/CD, profiling, and static analysis tools is preferred.
Experience leading or supporting remote teams of trainers, reviewers, engineers, coding mentors, or QAs is strongly preferred.
Highly organized and able to maintain style guides, FAQs, trackers, onboarding materials, honeypots, calibration tasks, and quality documentation.
Experience with AI training, data annotation, LLM evaluation, code QA, or rubric-based code review is a strong plus.
