We are seeking an experienced Application Security and Penetration Testing Engineer to strengthen the security of our enterprise web applications, APIs, and supporting services. This role will perform automated and manual security assessments, validate vulnerabilities, evaluate business risk, and collaborate with development teams to implement and verify remediation.

The ideal candidate will combine hands-on penetration testing expertise with a strong understanding of application architecture, secure software development, and healthcare data security requirements.

Key Responsibilities

• Conduct security assessments of web applications, APIs, and related services using automated vulnerability-scanning and DAST tools.
• Perform manual penetration testing to identify vulnerabilities that automated tools may not detect.
• Test authentication, authorization, session management, access controls, input validation, file handling, APIs, and application business logic.
• Identify issues such as broken access control, injection vulnerabilities, cross-site scripting, insecure configurations, information exposure, and privilege escalation.
• Validate automated scan findings, eliminate false positives, and determine the exploitability and business impact of confirmed vulnerabilities.
• Document findings with clear technical evidence, reproduction steps, severity, risk, business impact, and remediation recommendations.
• Work with development and architecture teams to review findings and recommend practical corrective actions.
• Retest remediated vulnerabilities and formally confirm their 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 sessions for development and QA teams.
• Stay current with emerging vulnerabilities, attack techniques, security tools, and application security best practices.

• Hands‑on experience with tools such as Burp Suite Professional, OWASP ZAP, Invicti, or comparable DAST and penetration‑testing platforms.
• Experience in manually testing authentication, authorization, session management, role‑based access, APIs, and business‑logic controls.
• Ability to validate findings independently and distinguish exploitable vulnerabilities from false positives.
• Ability to communicate technical vulnerabilities, business impact, and remediation guidance to both technical and leadership audiences.
• Strong analytical, documentation, collaboration, and problem‑solving skills.

Preferred Qualifications

• Experience securing healthcare applications or other systems that handle sensitive or regulated information.
• Knowledge of HIPAA, HITECH, HITRUST, SOC 2, NIST, and related security frameworks.
• Experience with SAST, software composition analysis, dependency scanning, secrets scanning, and SonarQube.

• Relevant certifications such as OSCP, OSWE, GWAPT, GPEN, CEH, or CISSP.

Success Measures

• Earlier identification of application and API security risks.
