Staff Product Security Engineer

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. As AI-assisted development accelerates code velocity faster than manual review can absorb, this role exists to close that gap structurally — through guardrails, automation, and platform-level prevention that scale with the engineering org.

Responsibilities

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 — including reusable rule packs and skills that shape how engineers and coding agents generate, review, and ship code; 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

Requirements

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 that improve security across many teams at once; Demonstrated ability to integrate security into developer workflows: CI/CD, code review, release processes, and internal platforms; Clear communicator who can explain technical detail and business impact to both engineers and leadership; Comfortable in fast-moving environments where AI-assisted development is reshaping how software is built and reviewed; Experience with vulnerability discovery and remediation pipelines, including bug bounty or researcher-reported findings; Track record of mentoring engineers and raising the technical bar across a security or platform engineering org

Nice to have

Experience securing AI/LLM systems, agentic workflows, or AI-assisted development tooling; Familiarity with authentication/authorization systems, cloud-native platforms, and how to secure them

Benefits

Equity in the form of restricted stock units; Commission depending on position offered; Medical, dental, and vision insurance; 401(k) program with employer match; Generous time off for vacation; Parental leave
