Senior Software Engineer, Security

SeatGeek is looking for a security engineering professional for our Security team. As a Senior Software Engineer, Security, you’ll be involved in a mix of security engineering, product security, incident response, and a trace of red teaming.

You’ll be involved with critical security initiatives that strengthen our secure-by-default posture across our platform, products, and company. You’ll pair architectural guidance with hands-on engineering — building paved roads, tooling, and automated detection/response that scale. You’ll operate in a fast-paced, collaborative environment, partnering with both engineering and non-engineering teams to reduce risk without slowing builders down. As a senior engineer, you'll own meaningful work end-to-end and help make the secure path the easy path — from cloud and code to laptops, identity, email, and awareness — including the AI tools reshaping how we build.

If this role sounds interesting to you, we encourage you to apply even if your experience doesn’t match every requirement - we value curiosity, collaboration, and a willingness to learn!

What You'll Do

• 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

• 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

You do not need experience with all of these, but we thought you might be curious. What we care about is your experience, skills, and approach to problem solving. Tools can be learned.
