Job description

About The Role

As an Application Security Engineer, you play a critical role in safeguarding DKSH's digital landscape by driving application security assurance across the full software development lifecycle. Your expertise in penetration testing, vulnerability management, and Application Security (AppSec) governance ensures that internal, third‑party, and internet‑facing applications are protected, resilient, and aligned with DKSH's security standards.

What You Will Deliver

• Coordinate and manage application penetration testing activities including scoping, scheduling, evidence collection, vendor coordination, report review, retest tracking, and closure validation to ensure testing outcomes are thorough and actionable.
• Conduct or support technical security assessments for web, Application Programming Interface (API), mobile, cloud‑hosted, and enterprise applications using manual testing and automated tools, delivering findings that drive meaningful risk reduction.
• Own application vulnerability tracking from discovery through to remediation, ensuring findings are categorized by severity, affected application, owner, risk, due date, and closure status to maintain full visibility and accountability.
• Provide clear and practical remediation guidance for vulnerabilities including SQL injection, Cross‑Site Scripting (XSS), authentication flaws, insecure direct object references, weak encryption, insecure configuration, vulnerable components, and missing logging.
• Support secure Software Development Lifecycle (SDLC) activities including security requirements, threat modeling inputs, secure coding guidance, release checks, and security sign‑off criteria to embed security throughout application delivery.
• Prepare executive and technical reports summarizing critical and high findings, remediation status, risk themes, aging, recurring weaknesses, and business impact to support informed decision‑making.
• Drive remediation coordination across application owners, developers, Quality Assurance (QA) teams, vendors, infrastructure, and security operations to ensure vulnerabilities are resolved effectively and on time.
• Influence application teams to validate closure based on evidence, ensuring remediation outcomes are substantive rather than administrative.
• Collaborate with Security Operations Center (SOC) and infrastructure teams to strengthen prevention and detection capabilities against application attacks, webshell risk, credential abuse, and exploitation attempts.
• Champion secure‑by‑design and risk‑based application delivery practices across the organization.

What You Bring

• Bachelor's degree in Cybersecurity, Computer Science, Software Engineering, Information Technology, or equivalent practical experience. Preferred certifications include GWAPT, GWEB, Offensive Security Certified Professional (OSCP), Practical Network Penetration Tester (PNPT), Certified Secure Software Lifecycle Professional (CSSLP), Certified Ethical Hacker (CEH), Security+, or equivalent.
• 5 or more years of cybersecurity experience with a focus on application security, penetration testing, vulnerability management, secure SDLC, or security assurance.
• Proven capability in application penetration testing coordination, report review, vulnerability validation, and remediation tracking.
• Strong knowledge of OWASP Top 10, API security, authentication and session management, secure coding, web server hardening, Web Application Firewall (WAF) concepts, and risk‑based remediation.
• Experience with tools such as Burp Suite, Invicti, OWASP ZAP, Qualys, Microsoft Defender, and Static Application Security Testing/Dynamic Application Security Testing/Software Composition Analysis (SAST/DAST/SCA) tooling, ticketing systems, and reporting dashboards is preferred.
• Ability to translate technical vulnerabilities into practical, actionable remediation guidance for developers, vendors, system teams, and management.
• Skilled in maintaining penetration test trackers, vulnerability aging reports, remediation dashboards, and risk acceptance documentation.
