• Architecture & Code Reviews: Actively participate in security architecture discussions, threat modeling sessions, and code audits alongside senior engineering teammates.
• Telemetry & Detection Engineering: Analyze security telemetry and support efforts to refine detection alerts, enhance monitoring, and update incident response playbooks.
• Documentation & Presentation: Document technical findings, develop clear architectural diagrams, and present a capstone internship project to engineering leadership.
  

Must Have(s)

• Currently pursuing a Bachelor’s, Master’s, or equivalent degree in Computer Science, Cybersecurity, Information Systems, or a related technical discipline.
• Foundational understanding of core information security concepts (e.g., cryptography, authentication/authorization, OWASP Top 10, network protocols).

• Familiarity with containerization tools (Docker, Kubernetes) and CI/CD pipeline automation (GitHub Actions, GitLab CI).
• Working knowledge of common web application vulnerabilities and practical defensive mitigation techniques.
Demonstrated passion outside the classroom, such as security research, open-source contributions, or active membership in university cybersecurity clubs/CTF teams.
