• Provide guidance on secure coding practices, vulnerability remediation and application hardening.
• Evaluate, implement and optimize application security tooling, including SAST, DAST and Software Composition Analysis (SCA).
• Integrate security controls and testing into CI/CD pipelines and engineering workflows.
• Support vulnerability triage, prioritization and remediation efforts across teams.
• Contribute to incident investigations, root cause analysis and long-term security improvements.
• Develop security standards, documentation, playbooks and developer guidance.
• Define and track security metrics to improve visibility, coverage and risk reduction.
• Evaluate emerging security technologies and help drive adoption of tools that create value for engineering teams.
• Promote secure AI-assisted development practices and responsible use of AI technologies.
• Foster a strong security culture through collaboration, enablement and knowledge sharing.

About You:

• Experience in Application Security, Product Security, Secure Software Development or a related field.
• Strong understanding of application vulnerabilities, secure coding principles and frameworks such as OWASP Top 10.

• Strong understanding of modern software development practices and developer workflows.
• Experience integrating security controls into development and delivery pipelines.
• Ability to assess security risks pragmatically and communicate effectively with both technical and non-technical stakeholders.
• Strong collaboration skills and experience working across engineering, product and security teams.
• Analytical mindset with a data-informed approach to prioritization and decision making.
• Experience evaluating security tools, technologies and vendor solutions.
• Familiarity with AI-assisted engineering workflows and secure adoption of AI technologies.
• Strong written and verbal English communication skills.

Experience in one or more of the following areas is a plus:

• API Security
