The Opportunity

We're seeking a highly technical Senior Product Security Engineer to embed security into the product development lifecycle. This is a hands-on engineering role responsible for identifying security risks early, partnering with development teams on remediation, conducting security reviews, performing application security testing, and helping build secure-by-design products.

This role will work closely with Engineering, Cloud Security, Infrastructure, Compliance, and Product Management to ensure security is integrated throughout the SDLC while enabling developer velocity.

What You'll Do

Application Security

• Perform security design and architecture reviews for new products and features.
• Conduct threat modeling for applications, APIs, and AI-enabled services.
• Review application security posture throughout the SDLC.
• Partner with engineering teams to prioritize and remediate vulnerabilities.
• Review authentication, authorization, and access control implementations.

Security Testing

• Perform manual web, API, thick-client, and mobile application penetration testing.
• Validate findings from third-party penetration tests.
• Conduct secure code reviews.
• Verify remediation of security vulnerabilities.

Secure Development

• Drive adoption of secure coding practices.
• Partner with developers to improve security throughout the SDLC.
• Help define Product Security standards and engineering guardrails.
• Develop reusable security patterns and reference architectures.

Vulnerability Management

• Triage findings from SAST, DAST, SCA, container scanning, and cloud security tools.
• Work with engineering teams to prioritize remediation.
• Track remediation SLAs and security metrics.

AI Security

• Assess AI-enabled products for security risks.
• Review LLM integrations and AI workflows.
• Test AI applications for prompt injection, data leakage, insecure tool use, model abuse, and authorization weaknesses.
• Help define secure AI engineering standards.

Security Automation

• Improve automation of security testing throughout CI/CD.
• Integrate security tooling into developer workflows.
• Build scripts and tooling that reduce manual security work.

Cross-functional Partnership

• Collaborate with Product, Engineering, Infrastructure, Cloud Security, and Compliance teams.
• Support customer security questionnaires related to product security.
• Assist Sales Engineering with security discussions when needed.

Qualifications

• 5+ years in Product Security or Application Security.
• Strong understanding of modern application architectures.
• Experience securing:
• Web applications
• APIs
• Microservices
• Cloud-native applications
• Experience performing threat modeling.
• Experience conducting penetration testing.
• Strong understanding of:
• OWASP Top 10
• OWASP API Top 10
• Authentication & Authorization
• OAuth / OIDC
• Secure SDLC
• Experience with SAST, DAST, SCA, and container security.
• Experience partnering directly with engineering teams.
• Strong written and verbal communication skills.

Preferred

• Experience securing AI/LLM applications.
• Experience with Kubernetes and containers.
• Familiarity with cloud security (AWS, Azure, or GCP).
• Experience with GitHub Actions or CI/CD security.
• Experience using:
• Snyk
• Burp Suite Pro
• Semgrep
• Wiz
• GitHub Advanced Security
• Security certifications such as OSCP, GWAPT, GWEB, CSSLP, or CISSP are a plus

What Success Looks Like

Within your first 12 months, you'll:

• Embed security into engineering workflows without slowing development.
• Improve vulnerability remediation timelines.
• Increase adoption of secure design reviews and threat modeling.
• Expand automated security testing across products.
• Help mature Iru's AI Security program.
• Strengthen Product Security standards and developer enablement.
• Build strong partnerships with engineering teams and become a trusted security advisor.

The ideal candidate should beengineering-first, comfortable reviewing architecture, threat modeling APIs and AI features, conducting hands-on testing, and partnering closely with developers—not someone focused primarily on governance or compliance. This profile will complement your broader security organization while helping scale Product Security as the platform grows.
