Code with Security in Mind: Participate in code reviews to learn how to identify potential security vulnerabilities and recommend secure coding practices to developers.
Innovate with LLMs: Experiment with LLMs and agent-driven frameworks to create new ways of detecting, classifying, and mitigating vulnerabilities in real time.

Strong knowledge of common vulnerabilities, exploitation techniques, and secure coding best practices.
Experience with mobile pentesting (Android/iOS), including relevant tooling and methodology.
Hands-on experience with security automation (Python, Go, or similar).
Bonus: Experience leveraging LLMs/agents for security tasks.
Proficiency in at least one scripting language (Python, Go, or similar).

Understanding of CI/CD pipelines and how to embed security checks into them.
Excellent communication and collaboration skills to work effectively with engineering teams.
