Job details

Contract | Remote | $50–$90/hour We’re looking for experienced Cyber Security Engineers to contribute technical expertise to a customer project focused on training and improving next-generation AI systems. In this role, you’ll use your real-world cybersecurity and software engineering experience to create, analyze, debug, and evaluate challenging technical scenarios. Your expertise will help AI models better understand secure software development, vulnerability analysis, debugging, and real-world engineering practices. No prior AI experience is required — your cybersecurity and software engineering expertise is what matters. What You’ll Do Analyze, debug, and resolve software bugs and security vulnerabilities across diverse codebases. Implement new features and improvements using languages such as Python 3, Java, Rust, Go, C++, or TypeScript. Refactor legacy code to improve maintainability, security, reliability, and performance. Conduct codebase reviews, security audits, penetration testing, and vulnerability assessments. Identify security risks and recommend practical mitigation strategies. Contribute to backend development and optimize applications for scalability, reliability, and security. Analyze real-world software and security scenarios and provide technically accurate solutions. Document technical findings, vulnerabilities, remediation approaches, and engineering decisions. Provide domain expertise and feedback that helps improve AI training datasets and model performance. What We’re Looking For Strong professional experience in cybersecurity, application security, software security, or security engineering. Proficiency in one or more of: Python 3 Java Rust Go C++ TypeScript Proven experience debugging complex software systems and resolving bugs. Strong knowledge of penetration testing, vulnerability assessment, security auditing, and secure coding practices. Experience with backend development and working with complex codebases. Strong understanding of algorithms, data structures, code refactoring, and performance optimization. Familiarity with secure software development lifecycle (SSDLC) and modern application security practices. Ability to analyze technical problems independently and explain findings clearly. Strong written and verbal English communication skills. Experience working with AI, machine learning, or data-driven projects is a plus, but not required. Ideal Background Candidates with experience in areas such as the following are encouraged to apply: Application Security Product Security Cloud Security Penetration Testing Vulnerability Research Security Engineering DevSecOps Backend Engineering Software Engineering with a strong security focus Offensive or Defensive Security Engagement Contract position Remote 15–20 hours/week $50–$90/hour, depending on experience and expertise Flexible schedule Opportunity to contribute to the development and evaluation of next-generation AI systems Selection Process Application & Screening Questions AI Interview – approximately 30 minutes Technical Assessment – tentative Hiring Manager Review Project Onboarding Why Join? Your cybersecurity expertise can directly contribute to how next-generation AI systems understand software security, vulnerability analysis, debugging, and secure engineering practices. You don’t need an AI background. Bring your cybersecurity expertise — and help shape how AI learns to solve real-world technical problems.
