Engineering Manager, Security
Perplexity · San Francisco
About this role
**ABOUT THE ROLE** Perplexity’s Security team protects products used by millions of people and thousands of enterprises—including AI agents that browse the web, run code, and act in customer systems. The team is small and senior, building much of what it uses: detections, agents that triage and investigate alerts around the clock, continuous offensive testing, and secure-by-default platforms for the rest of engineering. You’ll lead and grow **Security Engineering**, including the engineers building Perplexity’s cybersecurity products. You’ll own the team’s execution and people, set the technical direction for how we defend our infrastructure, products, and corporate environment, and lead product engineering work that brings those systems to customers. You’ll stay close enough to the work to run an incident or review a design yourself. You’ll report to Perplexity’s **Head of Security** and partner with engineering, infrastructure, IT, product, legal, and co-founders. --- **RESPONSIBILITIES** - Lead, hire, and grow a team of security engineers across: - detection and response - cloud and infrastructure security - application and product security - offensive security - identity and corporate security - Lead the engineers building Perplexity’s cybersecurity products: - set technical direction for agent-driven products across application security, offensive testing, cloud security, and detection/response - own delivery to design partners and enterprise customers - Keep the internal security program tightly linked to the product—so what the team runs internally becomes what we ship, and customer feedback improves our defenses. - Set the Security Engineering roadmap, balancing incident load, risk reduction, and long-term platform investments. - Own security incident response operations: - on-call health - escalation - cross-team coordination - postmortems that drive real fixes - Drive an **AI-first security program**: - automate investigation, response, and remediation with agents - hold automation to a high bar for accuracy and safety - Partner with engineering and infrastructure leaders to get security work into their roadmaps (threat models, design reviews, least-privilege access, secure-by-default libraries). - Represent Security Engineering in enterprise customer security reviews, external researcher/bug bounty engagements, and audits. - Build the team’s operating rhythm (clear ownership, meaningful metrics like time to detect/contain and open risk, and written standards others can follow). - Stay hands-on: review designs and code, run investigations when needed, and maintain a working understanding of the systems the team defends. --- **QUALIFICATIONS** - 8+ years of engineering experience in security, with at least 3 years managing security or infrastructure engineering teams. - Deep hands-on background in at least two of: - detection and response - cloud security (AWS preferred) - application or product security - offensive security - identity and access management - Experience leading incident response for serious security incidents (investigation, containment, and executive/customer communication). - Strong management practice (feedback, effective 1:1s, career development, and a track record of hiring/retaining senior engineers). - Comfortable with modern infrastructure (Kubernetes, cloud-native services, CI/CD) and able to engage credibly on design and code. - Ability to make good tradeoffs
