- Build and stabilize new AppSec processes and ways of working while ensuring legacy security controls remain fully active.
- Pioneer AI-driven automation to dramatically accelerate vulnerability triage and remediation, systematically burning down security backlogs.
- Provide hands-on technical fix guidance to developers for complex structural flaws and web application vulnerabilities.
- Drive developer security enablement across the organization—championing our Security Champions program and delivering engaging, impactful secure coding workshops.
- Partner closely with Platform and Infrastructure Security teams to build frictionless, automated guardrails into CI/CD pipelines.

What you need to bring:

- Deep, hands-on experience in Application Security, Product Security, or Secure Software Engineering in high-growth cloud environments.
- Bachelor's degree in Computer Science, Cybersecurity, or Software Engineering, or equivalent practical experience.
- Deep understanding of web application vulnerabilities (OWASP Top 10), business logic flaws, and secure coding practices.
- Proven track record tuning SAST, DAST, SCA, Secrets, and LLM scanner pipelines in CI/CD environments.
- Demonstrated experience with threat modeling methodologies, Secure by Design principles, and guiding developers through code remediations.
- Proven experience leveraging AI/LLM tools to automate security analyses, accelerate triage, and optimize developer security workflows.
- Fluency in modern software development languages (e.g., Python, Go, JavaScript/TypeScript, Java).
- Excellent cross-functional influence and communication skills to effectively lead the Security Champions program.
