As a Senior C++ Engineer, you will work remotely on an hourly paid basis to review AI-generated C++ code, systems designs, and technical explanations, as well as generate high-quality reference implementations and step-by-step reasoning for complex engineering problems. You will assess solutions for accuracy, clarity, safety, and adherence to the prompt; identify errors in logic, memory handling, concurrency, or performance; fact-check technical information; write high-quality explanations and model solutions that demonstrate correct methods; and rate and compare multiple AI responses based on correctness and reasoning quality.

This fully remote, hourly paid contractor role is with SME Careers, a fast-growing AI data services company and subsidiary of SuperAnnotate that provides AI training data to many of the world’s largest AI companies and foundation model labs, where your C++ and systems expertise will directly help improve the world’s premier AI models used by millions of developers worldwide.

Key Responsibilities :

Develop AI Training Content : Create detailed prompts in various topics and responses to guide AI learning, ensuring the models reflect a comprehensive understanding of diverse subjects.
Optimize AI Performance : Evaluate and rank AI responses to enhance the model's accuracy, fluency, and contextual relevance.
Ensure Model Integrity : Test AI models for potential inaccuracies or biases, validating their reliability across use cases.

Your Profile :

Bachelor’s degree or higher in Computer Science, Electrical / Computer Engineering, or a closely related technical field.

7+ years of professional experience developing production software in C++ for systems, performance-critical, or large-scale applications.

Expert-level proficiency in modern C++ (C++11 and later), including templates, move semantics, smart pointers, and the STL.

Strong background in systems programming concepts such as concurrency, operating systems, low-level performance optimization, and memory management.

Hands-on experience with C++ build systems, compilers, linkers, debuggers, and profiling or analysis tools.

Minimum C1 English proficiency (written and spoken), with the ability to write clear technical explanations and follow detailed English-language guidelines.

Proven experience conducting detailed C++ code reviews and enforcing coding standards for safety, performance, and maintainability.

Comfort working with version control, CI / CD workflows, and automated testing frameworks in modern C++ projects.

Previous experience with AI data training, annotation, or evaluating AI-generated technical content is a strong plus.

Highly detail-oriented and systematic, with a methodical approach to evaluating reasoning quality and identifying subtle issues in complex C++ code.
