Detection & CorpSec Engineer

Quora's Security team is responsible for protecting the company's most critical assets from both external threats and insider risks. We're a small, high-ownership team with a pragmatic, builder-oriented approach: we build where commercial solutions don't fit, leverage AI to work efficiently at scale, and move fast to stay ahead of real-world threats.

We're looking for a Detection & Corporate Security Engineer to strengthen both our preventative and detection capabilities across corporate and production environments. This is a genuinely hybrid role: you'll build and maintain detection systems while also owning the corporate security controls that protect our employee fleet and internal infrastructure. You'll work closely with our IT team, collaborate with existing security engineers on production-side coverage, and serve as a trusted security advisor to non-technical teams across the organization.

- Build and maintain a SIEM to collect and analyze logs from across corporate and production systems; write and deploy detections and alerts to identify malicious behavior

- Design and deploy canary tokens and early warning mechanisms to detect threats before they reach critical assets

- Investigate security incidents end-to-end — including malware analysis, exfiltration assessment, and timeline reconstruction — and build runbooks to scale response capabilities

- Partner with IT to define and enforce security standards across the employee device fleet, including endpoint protection, managed device requirements, OS compliance, and VPN access controls

- Drive the PoC and implementation of Zero-Trust VPN and other corporate security infrastructure

- Provide security guidance and advisory support to non-engineering functions across the organization

- Availability for meetings and impromptu communication during Quora's “coordination hours https://quora.com/coordination_hours" (Mon-Fri: 9am-3pm Pacific Time)

- 5+ years of experience in security engineering, detection engineering, or a closely related field

- Hands-on experience building or maintaining SIEM infrastructure and writing detection rules
