Staff Product Security Engineer

About the Role

Reddit is hiring a Staff Product Security Engineer to make the secure path the easiest path for engineers and AI agents. You'll lead the design and delivery of secure frameworks, paved paths, and workflow-native controls that eliminate recurring vulnerability classes before they reach production.

What You'll Do

• Build and evolve secure frameworks, guardrails, and library-level controls that make common vulnerability classes harder to introduce.
• Design security controls for AI-assisted development.
• Embed security into the workflows engineers already use.
• Drive product security reviews for new launches and major architectural changes.
• Identify and eliminate systemic security debt.
• Shape strategy, influence architecture, and drive execution across teams.

What We're Looking For

• 8+ years of experience in software engineering, product security, or application security, with at least 2 years operating at a staff level of scope and impact.
• Proficiency in one or more languages (Go, Python, JS/TS).
• Experience designing, building, and operating production-quality systems and developer-facing platforms.
• Experience building secure frameworks, libraries, or guardrails.
• Demonstrated ability to integrate security into developer workflows.
• Clear communicator who can explain technical detail and business impact.
• Comfortable in fast-moving environments.
• Experience with vulnerability discovery and remediation pipelines.
• Track record of mentoring engineers.

Preferred Qualifications

• Experience securing AI/LLM systems.
• Familiarity with authentication/authorization systems.
