• Provide practical engineering and cybersecurity insights that can strengthen AI training and evaluation datasets.

What We’re Looking For

• Strong proficiency in one or more of Python, Java, Rust, Go, C++, or TypeScript.

• Proven experience debugging and fixing software issues in complex codebases.

• Backend development experience and strong software engineering fundamentals.

• Hands-on cybersecurity experience, including penetration testing, security audits, and vulnerability assessment.

• Knowledge of algorithms, codebase refactoring, and performance optimization.

• Understanding of secure software development practices and modern cybersecurity threats.

• Ability to analyze technical problems and communicate findings clearly and concisely.

• Strong attention to detail and practical problem-solving skills.

• Experience with AI, machine learning, or data-driven projects is useful but not required.

Assessment & Selection Process

The process may include:

1. Application and screening questions

2. Approximately 30-minute AI interview

3. Technical assessment, if required

4. Hiring manager review

Schedule & Engagement

• Remote contractor engagement

• Approximately 15 hours per week

• Flexible schedule — choose the hours and days that work for you, including weekends if preferred

• Work is output-based, with compensation tied to tasks that meet project specifications
