Job description

Senior Software Security Engineer AI Trainer

The work

You will create training and evaluation tasks for AI coding models. The work turns real software vulnerabilities into audit and patch exercises that test whether a model can identify, understand, reproduce, and securely fix a security issue.

You will work with vulnerabilities from CVEs, security advisories, bug reports, and open-source repositories. You will also review AI-generated patches and reasoning against technical rubrics.

• Classify vulnerabilities using the most specific applicable CWE and relevant OWASP Top 10 categories.
• Reproduce vulnerabilities and write reliable proof-of-vulnerability tests.
• Write realistic task instructions and create reproducible Docker environments with pinned dependencies.
• Harden verifiers against gaming and test manipulation.
• Review AI-generated code patches and explanations using technical evaluation rubrics.

Requirements

This is a remote contractor role for at least 20 hours per week. The work requires professional software engineering experience, strong software security knowledge, and the ability to work independently in a research-focused setting.

• At least five years of professional software engineering experience.
• Expert proficiency in at least one supported programming language.
• Professional fluency in English.
• Strong knowledge of CWE, CVE, and the OWASP Top 10.
• Ability to reproduce vulnerabilities and write proof-of-vulnerability tests.
• Experience with sanitizers, fuzzers, and static analysis tools such as CodeQL or Semgrep.
• Strong Git, Linux, Bash, Docker, technical writing, and documentation skills.
• Open to candidates worldwide.

Preferred

• Experience building security benchmarks, analyzing open-source vulnerabilities, creating automated tests, or evaluating code patches is helpful.

Lead a remote pod creating and reviewing software security tasks for AI coding models. This expert contract role requires 20+ hours weekly, six years of software engineering experience, and strong vulnerability research skills.

Complete coding-heavy AI training tasks involving machine learning models, Python, evaluation systems, and performance optimization. Work remotely for about 15 hours per week, with $60 to $120 per hour equivalent, paid per accepted task.

Build and run electromagnetic and circuit simulations for high-speed PCB designs, analyze signal behavior, and automate workflows with Python. This contract role is open worldwide and requires strong signal integrity and electromagnetic engineering skills.

Help build, evaluate, and improve coding datasets used to train and benchmark advanced AI language models. This contractor role is open to entry-level engineers in Egypt with strong computer science skills and C# and C++ experience.

Create realistic bugs, features, refactoring, and performance tasks that test AI coding ability. This part-time contractor role pays $50 to $100 per hour equivalent, paid per task that meets project specifications.
