Job Description

Agadia Systems Inc seeks an Application Security and Penetration Testing Engineer to strengthen enterprise web application and API security through automated and manual testing, validation, and remediation collaboration.

Responsibilities

Conduct security assessments of web applications, APIs, and supporting services using automated vulnerability scanning and DAST tools.
Perform manual penetration testing to uncover vulnerabilities that automated tooling may miss.
Test authentication, authorization, session management, and access controls, including role-based and business-logic enforcement.
Evaluate input validation, file handling, API behavior, and application business logic.
Identify and assess issues including broken access control, injection, cross-site scripting, insecure configurations, information exposure, and privilege escalation.
Validate scan results by eliminating false positives and determining exploitability and business impact for confirmed vulnerabilities.
Document findings with technical evidence, reproduction steps, severity, risk, business impact, and remediation recommendations.
Partner with development and architecture teams to review results and recommend practical fixes.
Retest remediated issues and formally confirm vulnerability closure.
Support secure design reviews, threat modeling, code reviews, and release-readiness assessments.
Help integrate application security testing into the software development lifecycle and CI/CD pipelines.
Maintain vulnerability status, remediation timelines, risk exceptions, and security assessment reports.
Support internal audits, customer security reviews, and external penetration-testing activities.
Provide application security guidance and knowledge-sharing for development and QA teams.
Stay current on emerging vulnerabilities, attack techniques, security tools, and application security best practices.

Requirements

Bachelor’s degree in Computer Science, Cybersecurity, Information Technology, or a related discipline (or equivalent professional experience).
5+ years of information security experience, including at least 3 years hands-on web application and API penetration testing.
Strong knowledge of OWASP Top 10, OWASP API Security Top 10, CWE, CVSS, and common application attack techniques.
Hands-on tool experience with Burp Suite Professional, OWASP ZAP, Invicti, or comparable DAST and penetration-testing platforms.
Ability to manually test authentication, authorization, session management, role-based access, API controls, and business-logic enforcement.
Capability to validate findings independently and differentiate exploitable vulnerabilities from false positives.
Knowledge of HTTP/HTTPS, REST APIs, cookies, tokens, browser security controls, and web application architecture.
Familiarity with secure coding practices and application security considerations for .NET and JavaScript-based applications.
Ability to communicate technical vulnerabilities, business impact, and remediation guidance to technical and leadership audiences.
Strong analytical, documentation, collaboration, and problem-solving skills.
