About The Position

LinkedIn’s Trust Investigations team is seeking a Trust Technical Investigator to manage fraud and scams. The role develops and applies approaches to detect, understand, and mitigate coordinated, persistent, and high-harm activity by adversarial actors, supporting a safe and trustworthy experience for LinkedIn members. The investigator partners closely with Product, Engineering, and Data Science in an AI-first trust environment.

The role leads complex investigations and incidents and uses case insights to develop and maintain detection rules, data pipelines, and runbooks that help stop scam activity at scale. Investigative findings also inform product vulnerability assessments and risk recommendations, in partnership with intelligence and product-risk teams.

This is a hybrid role based at LinkedIn’s Mountain View campus, performed both from home and from a LinkedIn office on select days according to business needs.

Requirements

• Bachelor’s degree in Cyber Security, Criminal Justice, or another related technical discipline, or equivalent technical experience.
• At least 3 years of experience with scripting or data analysis tools such as SQL or Python, and the ability to synthesize complex data into actionable insights.
• At least 3 years of experience conducting proactive threat investigations of account, content, or behavioral abuse in trust and safety, social media, online platforms, or fintech, including meaningful direct experience with fraud or scams.
• At least 3 years of experience with investigation techniques and tools and evidence handling, including work across diverse structured and unstructured data sets.

Nice To Haves

• BS and 5+ years of relevant work experience, MS and 4+ years of relevant work experience, or PhD and 2+ years of relevant work experience.
• Direct experience building or maintaining detection rules, alerting logic, or data pipelines, rather than only consuming them.
• Strong technical acumen and ability to translate data and investigative outcomes into actionable insights for engineering, AI, and senior leadership partners.
• Experience leading proactive threat or fraud hunting against large-scale, coordinated abuse.
• Experience with frameworks such as MITRE ATT&CK or the cyber kill chain, and ability to adapt them to social-platform scam typologies.
• Demonstrated ability to navigate cross-functional dependencies and drive collaboration across engineering, product, data science, and legal teams.
• Excellent written and verbal communication skills and ability to influence across all organizational levels.
• Experience mentoring or developing other investigators.
• Experience working in global teams across multiple locations and time zones.

Responsibilities

• Lead root-cause investigations into complex, coordinated, or high-impact scam campaigns and abuse networks, from initial leads through resolution.
• Serve as incident commander for major scam-related incidents, coordinating response and ensuring timely, accurate resolution.
• Generate proactive investigative leads and track emerging coordinated threat activity relevant to scams and fraud.
• Author detection rules and data pipelines tailored to scam patterns and typologies.
• Innovate on investigative tradecraft and stay current on tools, techniques, and adversary tactics across the fraud and scams landscape.
• Partner with Engineering and Data Science to build and refine analysis, threat-hunting, and scam mitigation capabilities.
• Develop technical playbooks to help the broader team scale its investigative work.
• Partner with intelligence and product-risk teams so investigative findings and intelligence inform product planning and risk posture.
• Collaborate with Product, Engineering, Data Science, Legal, and Policy partners to align investigative priorities with product roadmaps and trust and safety strategy.
• Represent the technical substance of the team’s work in cross-functional forums and externally to peers in the sector.
• Mentor investigators in technical, investigative, and tooling capabilities, fostering rigor and continuous learning.

Benefits

• Generous health and wellness programs.
• Time away for employees of all levels.
• The total compensation package may include an annual performance bonus, stock, benefits, and/or other applicable incentive compensation plans.
