SeatGeek is looking for an Application Security Engineering Intern to join our Security team. As an intern in AppSec, you’ll focus on securing our applications by conducting threat assessments, bug hunting, code reviews, and assisting in red teaming activities. 

You’ll join a team leading a proactive application security program focused on securing SeatGeek’s development life cycle. Emphasizing early detection, automated remediation, and structured security reviews, we aim to create a secure-by-default environment across our applications. Collaborating closely with developers, you’ll play a key role in future-proofing our security practices by enhancing CI/CD scans, conducting architecture and code reviews, and building tools to integrate security throughout the organization. This role will empower you to drive meaningful impact, strengthening SeatGeek’s overall security posture for the long term.

What you have

• You’re graduating in Spring 2026
• Proficiency in two or more programming languages (Python, C#, Go) and a solid grasp of coding and code review (yes, there’s a coding interview).
• Ability to think like an attacker when securing applications, using that mindset to identify potential vulnerabilities and drive meaningful improvements in code security and defensive measures.
• Understanding of secure software development practices, threat modeling, and knowledge of common security vulnerabilities (like OWASP Top Ten).
• Experience contributing to the security community (public research, blogging, presentations, etc.)
• (Preferred) Experience or strong interest in automating security tasks and scaling security processes through tooling.
• (Preferred) Familiarity with modern architectures, including microservices, Kubernetes, AWS, and other cloud technologies.
• (Preferred) Regularly participate in CTF, bug bounty hunting, and hackathons (bonus points if you share your Bugcrowd/HackerOne/HackTheBox profiles)
