• 100% remote

• Part-time

• About 15–20 hours a week, you choose when

Work on the cutting edge of AI, on your own schedule, and get paid for the cybersecurity expertise you already have.

The AI systems everyone is talking about are trained and tested by real security engineers. The teams building them need people who can work through real bugs and vulnerabilities, judge how well the AI handles them, write the fix and recommendations a security professional would give, and explain exactly where the AI falls short. Your judgment becomes part of how the next generation of AI models handles software and security problems. This is that work, done remotely, around your current job.

What you’ll do

• Track down and fix bugs and security flaws in a range of real codebases

• Run codebase audits, penetration tests and vulnerability assessments

• Improve backend features and refactor older code for security, maintainability and performance

• Write up what you found and suggest concrete fixes that make the AI training data better

Why this is worth your time

• Get paid the equivalent of $30–$100 an hour to build real AI skills, on top of your current job

• Work directly with frontier AI tools for code and security review and see how they are built, tested and improved, experience most security engineers will not have for years

• Build a career edge for what comes next: AI is reshaping security engineering, and the people who understand it from the inside will lead that change

• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• Professional coding ability in Python 3, Java, Rust, Go, C++ or TypeScript, including writing, debugging and optimization

• Cybersecurity experience such as penetration testing, security audits or vulnerability assessments, plus knowledge of secure software development processes and the current threat landscape

• Clear written and spoken English, with the ability to communicate technical findings in a clear way

• No AI experience needed. You bring the expertise; we bring the training on the tools.

Pay and details

• $30–$100 per hour equivalent; pay is per accepted task, as an independent contractor

• About 15–20 hours a week, you choose when; fully remote, United States
