About the Role:

We are looking for an experienced Application Security Analyst to join us on a freelance basis, supporting security testing across both web and mobile applications, with a strong emphasis on Flutter-based mobile apps. This is a non-exploit role, focused on identifying vulnerabilities and security weaknesses—not active exploitation or red teaming.

The role is fully remote and well-suited for professionals who are comfortable working independently on a long-term, as-needed basis. Hours will vary with workload, so flexibility and the ability to work asynchronously are key.

Key Responsibilities:

• Conduct manual and tool-assisted penetration testing of web and mobile (Flutter) applications
• Identify vulnerabilities related to authentication, authorization, session handling, and insecure storage or communications
• Perform reviews of Dart/Flutter code and assess mobile-specific risks like deep linking, reverse engineering, and tampering
• Analyze APIs and backend integrations for security gaps
• Document findings in detailed, developer-ready reports including impact assessments and remediation guidance
• Collaborate with internal teams to clarify security concerns and verify remediations
• Align all assessments with OWASP Top 10, OWASP MASVS, and secure coding best practices
• Operate in a non-exploitative capacity (no red teaming or social engineering)

Required Experience and Skills:

• Minimum 4–6 years of experience in application security testing
• Strong background in Flutter security, with hands-on testing of production-grade mobile apps
• Proficiency in tools such as Burp Suite, OWASP ZAP, MobSF, Frida, Postman, Objection, or similar
• Familiarity with mobile and web security standards (OWASP Top 10, MASVS, CVSS, CWE)
• Excellent technical writing and reporting skills
• Certifications like OSCP, eWPT, GMOB, or equivalent are a plus
• Experience working as an external security consultant or independent contractor
• Familiarity with CI/CD security practices and DevSecOps pipelines
• Ability to scope and prioritize assessments autonomously

Compensation and Workload:

• Competitive hourly or daily rate
• Project-based workload, long-term commitment
