Job Specifications

About the Client:

Our cybersecurity startup client leverages AI and advanced automation to detect threats on both the web client and browser sides, with applications across various real-world security use cases.

The Opportunity:

This is a ground-floor opportunity to move beyond "traditional" security. You will be responsible for building the security protocols and automated guardrails that ensure our client’s platform remains a "secure-by-default" experience for thousands of global users and organizations.

The Skills/Requirement Needed to Succeed:

8–10+ Years of Application & Product Security Depth: Extensive experience securing complex, distributed platforms and a mastery of the OWASP Top 10. You should have a proven track record of identifying and mitigating vulnerabilities in high-traffic production environments.
Mastery of Web & JavaScript Security Internals: Deep technical expertise in how modern browsers and web applications interact. You are a specialist in front-end attack surfaces, including protecting against supply chain attacks, digital skimming, and unauthorized third-party script execution.
Cloud-Native & DevSecOps Architecture (AWS): Expert-level experience building and automating security protocols within AWS. You understand how to bake security into CI/CD pipelines to enable a friction-free PLG motion while maintaining enterprise-grade protection.
Security Leadership & Certification: You bring the technical maturity to lead audits and define global security standards. A major "nice-to-have" is a professional Tier 1 certification such as CISSP, CCSP, or CISM, or a deep technical credential like AWS Certified Security – Specialty or OSCP.
