C Engineer

About the Role

As a C Engineer, you will work remotely on an hourly paid basis to review AI-generated C code, low-level systems designs, and technical explanations, and to 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.

Additional Information

• There is no immediate project for this role; if qualified, you will be among the first experts contacted when relevant opportunities arise.

Responsibilities

• Review and evaluate AI-generated C code, low-level designs, and technical explanations for accuracy, safety, and adherence to prompts.
• Identify and report errors in logic, memory handling, concurrency, performance, and undefined behavior.
• Create high-quality reference implementations and step-by-step solutions for complex systems problems.
• Write clear technical explanations and model solutions that demonstrate correct methods.
• Assess, rank, and compare multiple AI responses to improve model accuracy, fluency, and contextual relevance.
• Develop detailed prompts and training content to guide AI learning across system-level C topics.
• Test AI outputs for inaccuracies or biases and validate model reliability across use cases.

Qualifications

• Bachelor’s degree or higher in Computer Science, Electrical/Computer Engineering, or a closely related technical field.
• 4+ years professional experience developing production software in C for systems, embedded, or performance-critical applications.
• Expert-level proficiency in C, including deep understanding of pointers, memory management, undefined behavior, and low-level debugging.
• Strong background in systems programming concepts such as concurrency, operating systems, hardware interaction, and performance optimization.
• Hands-on experience with build systems, compilers, linkers, and debugging tools commonly used in C development.
• Proven experience conducting detailed code reviews and enforcing coding standards for safety and maintainability in C codebases.
• Comfort working with version control, CI/CD workflows, and automated testing for C projects.
• Minimum C1 English proficiency (written and spoken) with the ability to write clear technical explanations and follow detailed English-language guidelines.
• 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 low-level code.
