The role will also support counterintelligence-related responsibilities, including awareness of foreign influence, corporate espionage, elicitation, and other potential threats that may affect EY professionals, client work, or firm operations.

Your key responsibilities

Lead sensitive and complex investigations related to insider risk, behavioral threats, workplace concerns, information protection, technology misuse, and business risk, leveraging multidisciplinary investigative methodologies to identify risks, inform decision-making, and protect the organization’s people, assets, and reputation.
Assess potential insider risk indicators, concerning behaviors, unauthorized access, data handling issues, workplace threat concerns, policy violations, and other risks requiring coordinated security review.
Make factual findings, synthesize complex information, assess credibility and context, and apply EY policies, procedures, investigative standards, and risk mitigation principles.

Partner with US Security leadership, Cyber/IT, Data Loss Prevention, General Counsel’s Office, Ethics and Compliance Investigations Team, Talent, Employee Assistance, business leaders, and other stakeholders to coordinate investigative activity and mitigation strategies.
Support an integrated investigative model that promotes timely triage, escalation, response coordination, and consistent handling of sensitive matters.
Conduct root cause and trend analyses to identify emerging risks, recurring vulnerabilities, control gaps, policy clarification needs, training opportunities, and continuous improvement recommendations.
Develop, refine, and apply investigative processes, protocols, playbooks, templates, and documentation standards that support thoroughness, fairness, confidentiality, consistency, and defensible decision-making.
Provide consultation and subject matter support to leaders and stakeholders on sensitive, high-risk matters requiring discretion, sound judgment, and understanding of security, employment, compliance, and business considerations.
Support awareness, prevention, and change management efforts designed to strengthen EY’s insider risk, workplace safety, information protection, and security culture.
Maintain awareness of emerging insider risk, workplace threat, corporate security, counterintelligence, and information protection trends relevant to professional services organizations.
Partner with intelligence and analytical teams to ensure investigations and risk mitigation activities are informed by timely, actionable intelligence and emerging threat trends.

Counterintelligence-related responsibilities

Support counterintelligence-related activity in coordination with US Security leadership and appropriate internal stakeholders.
Identify and escalate potential indicators of foreign influence, elicitation, corporate espionage, targeting of EY professionals, unauthorized collection efforts, or other matters that may require specialized review.
Help translate counterintelligence awareness into practical guidance for relevant investigative, security, and business stakeholders.
Coordinate with internal partners, and where appropriate through established channels, to support risk assessment, information gathering, documentation, and mitigation planning.
Contribute to awareness materials, briefings, or prevention efforts related to counterintelligence risks in a manner aligned with EY policies and legal requirements.
Participate in industry and government security forums (e.g., DSAC, InfraGard, OSAC) to maintain awareness of evolving counterintelligence threats and foreign adversary tactics.
