A bit about the role
The Application Security Engineer is responsible for ensuring the security of software applications through rigorous testing and validation. This role is dedicated to embedding security testing throughout the software development lifecycle (SDLC), identifying vulnerabilities, and supporting development teams in remediating security issues. The focus is on proactive, continuous security assessment of applications, both pre- and post-deployment, to maintain the highest standards of software security.
What you'll be doing
- Collaborate with development teams to create and maintain application threat models (e.g., STRIDE, DREAD).
- Identify and document application-specific risks; propose effective countermeasures.
- Integrate and operate application vulnerability scanning tools (e.g., Sonar Cloud, Snyk, OWASP ZAP, Burp Suite, Tenable WAS) within CI/CD pipelines.
- Interpret vulnerability reports, prioritise remediation based on risk, and track resolution with development teams.
- Promote awareness of common application vulnerabilities (e.g., SQL injection, XSS, CSRF) and mitigation strategies (OWASP Top 10, ASVS, MASVS).
- Support development teams in adopting secure coding standards, including static analysis tools, code reviews, and automated linting.
- Plan, execute, and manage Static, Dynamic, Mobile, and Interactive Application Security Testing (SAST, DAST, MAST, IAST).
- Embed security testing into CI/CD pipelines for continuous, automated validation.
- Simulate real-world attack scenarios to identify weaknesses in application logic and implementation.
- Develop and maintain scripts, tools, and processes to automate application security testing.
- Produce clear, actionable security testing reports for technical and non-technical stakeholders.
- Maintain comprehensive documentation of testing methodologies, findings, and remediation guidance.
- Work closely with software engineers, QA, and product teams to embed security best practices.
- Deliver training and awareness sessions on application security testing techniques and secure development.
