In this role, you'll develop and apply approaches to detect, understand and mitigate coordinated, persistent, and high-harm activity from highly adversarial actors, helping ensure a safe and trustworthy experience for LinkedIn members.

Our teams work in close partnership with product, engineering, and data science partners dedicated to advancing our visibility, controls and measurement. In this role you will run investigations and contribute to building our technology as we operate an AI-first trust environment: you'll lead complex investigation and incidents, using case insights to develop and maintain our detection rules, pipelines, and runbooks that help LinkedIn stop scam activity at scale. Our investigations drive product vuln assessments and risk recommendations, so you’ll work with our intelligence and product-risk teams to ensure findings inform how the company builds and protects its products going forward.

• Develop technical playbooks that help the broader team scale its investigative work.

Cross-Functional Partnership & Vulnerability Reporting

• Partner with intelligence and product-risk teams to ensure investigative findings and intel inform product planning and risk posture.
• Collaborate with Product, Engineering, Data Science, Legal, and Policy partners to align investigative priorities with product roadmaps and the broader trust and safety strategy.
• Represent the technical substance of your team's work in cross-functional forums and externally to peers in the sector.

Quality & Mentorship

Preferred Qualifications

• Master's Degree in cyber security, criminal justice, computer science, or a related technical discipline.
