Role overview

Reddit is hiring a Staff Product Security Engineer to make the secure path the easiest path for engineers and AI agents. You will lead the design and delivery of secure frameworks, paved paths, and workflow-native controls that eliminate recurring vulnerability classes before they reach production. This role focuses on guardrails, automation, and platform-level prevention that scale with the engineering organization, including controls for AI-assisted development.

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 organization.

Preferred qualifications

• 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.

Compensation and benefits

• Base salary range (US): $217,000 - $303,900 USD.
• Eligible to receive equity in the form of restricted stock units and, depending on the position, may also be eligible for a commission.
• Benefits for U.S.-based employees include medical, dental, and vision insurance; 401(k) program with employer match; generous time off for vacation; and parental leave.

Interview & privacy

• In select roles and locations, interviews may be recorded, transcribed, and summarized by AI. Candidates may opt out of recording, transcription, and summarization prior to scheduled interviews.
• During the interview, Reddit will collect categories of personal information (identifiers, professional/employment information, sensory information such as audio/video) to evaluate applications. Recordings are deleted after hiring decisions; see the Candidate Privacy Policy for details.
