  - user experience design or research
  - digital forensics and incident response
- Deep understanding of web application vulnerabilities (e.g., **OWASP Top 10**), client-side security, and common API security flaws
- Collaborate with engineering teams to promote secure coding practices and provide targeted security guidance and training
- Knowledge of cryptographic primitives and protocols
- Knowledge of common networking protocols

**Team Fit**
- Ability to give and process constructive feedback
- Ability to work independently and collaboratively
