What you have:

- 3+ years of experience in Application Security, Penetration Testing, or Product Security in a SaaS company
- Deep understanding and hands-on experience of web application security, including OWASP Top 10, authentication, encryption, and secure coding principles
- Proficiency in scripting or programming languages (Terraform, Python, JavaScript, Go, etc.) for security automation and infrastructure.
- Experience with cloud security best practices (AWS, GCP, or Azure)
- Strong communication skills, with the ability to explain security risks and recommendations to technical and non-technical stakeholders, including executive management
- Experience working with large-scale, complex R&D environments

Bonus Points:
