[Remote] Senior Software Engineer, Security

Note: The job is a remote job and is open to candidates in USA. SeatGeek is a company focused on modernizing the ticketing industry through technology and a fan-first approach. They are seeking a Senior Software Engineer specializing in security to enhance their security posture across various platforms and products, collaborating with multiple teams to implement secure practices and tooling.

Responsibilities

• Build and contribute to secure-by-default protections across the stack (cloud, CI/CD, applications, and endpoints) by creating paved roads and guardrails that make the secure path the easy path within your problem space
• Provide practical security guidance on new products and technologies, recommending secure-by-default patterns that fit into existing workflows
• Help secure SeatGeek's use of AI — from LLM-assisted development to AI-powered product features — by building guardrails and reviewing for risks like prompt injection, sensitive-data exposure, and insecure model and tool integrations
• Contribute to design reviews and threat modeling for high-impact features and services; surface risks early and help ensure mitigations are designed in
• Build security tooling that prevents issues at build/deploy time and helps automate detection and response in production
• Improve our detection and incident response capabilities — raise signal quality, tune detections, and implement automated responders that reduce manual toil and time to contain
• Partner with engineering and business teams on cross-functional security work: endpoint and device trust, identity and email protections, security awareness and training, vendor reviews and risk assessments, and supporting compliance efforts (e.g., PCI/SOX)
• Protect SeatGeek from abuse and bots at the edge and app layers through layered defenses and tuning
• Contribute to security incidents and tabletops, including writing incident reviews; help improve runbooks, processes, and stakeholder communications afterward
• Advocate for strong secure coding practices and contribute to a pragmatic, positive security culture across your team and partner teams

Skills

• 3+ years of broad, hands-on experience across multiple security domains, with strong software engineering fundamentals; track record of driving security projects end-to-end (from design through rollout and adoption)
• Proficiency in one or more programming languages (we use Python, Go, and C#); you write production-quality code and perform rigorous reviews for correctness and security
• Experience partnering across product, platform, and business functions to contribute to cross-team security outcomes
• Ability to build scalable, preventative security solutions across domains (platform/cloud, applications, CI/CD, identity and endpoints), favoring reusable guardrails over one-off fixes
• Ability to think like both an attacker and a defender — leveraging each perspective to strengthen the other and drive meaningful improvements in prevention, detection, and response
• Familiarity with the security implications of AI/LLM systems — LLM-assisted development, prompt injection, data leakage, and securing model/agent integrations — is a plus
