Accountabilities: The Senior Offensive Security Engineer will be responsible for proactively identifying and validating security risks through realistic attack simulations. The role focuses on uncovering vulnerabilities that create meaningful business impact and improving the overall security posture through collaboration and technical expertise.

• Identify, validate, and demonstrate realistic attack paths across applications, infrastructure, and internal systems.

• Analyze complex, multi-language codebases using both manual techniques and AI-assisted approaches to discover vulnerabilities and generate exploit hypotheses.

• Develop safe proof-of-concept exploits demonstrating risks such as unauthorized access, privilege escalation, data exposure, and business logic flaws.

• Partner with engineering teams to validate fixes, confirm vulnerabilities are fully resolved, and identify similar security patterns across the environment.

• Document findings with clear technical evidence, root cause analysis, business impact, and actionable remediation guidance.

• Continuously improve offensive security methodologies, testing coverage, and internal security capabilities.

• Leverage AI tools as part of daily workflows to accelerate security research, analysis, and delivery.

Requirements:

The ideal candidate brings deep offensive security experience, strong technical knowledge of modern application environments, and the ability to communicate complex security findings effectively. You should be comfortable combining security expertise with emerging AI technologies to improve testing efficiency and coverage.

• 5+ years of experience in offensive security, application security, penetration testing, or red team environments with proven success identifying real-world vulnerabilities.

• Strong expertise in web applications, APIs, authentication, authorization, distributed systems, and OWASP Top 10 security risks.

• Experience creating proof-of-concept exploits that demonstrate practical business impact rather than theoretical vulnerabilities.

• Proficiency using AI tools for vulnerability discovery, exploit development, code analysis, and security research while independently validating results.

• Strong understanding of secure development practices and vulnerability remediation strategies.

• Excellent communication skills with the ability to explain technical issues, attack paths, and recommendations to engineering stakeholders.

• A proactive mindset with a strong interest in using AI to improve productivity, problem-solving, and security research.

Benefits:

• Competitive base salary starting at $170,000+, depending on experience.

• Incentive Stock Option (ISO) grant eligibility, subject to approval.

• Fully remote work environment with flexibility across the United States and Canada.

• Comprehensive medical, dental, and vision coverage with premiums fully covered for employees and partially covered for dependents.

• Unlimited paid time off and sick leave, plus 14 company holidays.

• 100% 401(k) match up to 4% with immediate vesting.

• Competitive parental leave benefits for all parents.
