Powered by patented Attack Signal Intelligence, it empowers security teams to rapidly prioritize, investigate and respond to the most advanced cyber-attacks. With 35 patents in AI-driven threat detection and the most vendor references in MITRE D3FEND, organizations worldwide rely on the Vectra AI to move at the speed and scale of hybrid attackers. For more information, visit www.vectra.ai. \n*This is a hybrid role for San Jose, CA; Austin, TX; Boston, MA; or Dublin, Ireland\nPosition Overview\nVectra AI’s Security Research team studies how attackers operate and turns that knowledge into capabilities that help customers find and respond to threats. We are looking for a Senior Security Researcher to help define and investigate the security challenges created by enterprise AI adoption and AI-enabled attackers.\nYou will study how agents, copilots, AI-connected applications, and their identities can be misused or compromised. You will also examine how attackers use AI to accelerate familiar attack techniques. Your research will connect activity across identity, cloud, and network environments, with a focus on what customers can observe, investigate, and act on. This is an emerging area: you will help test assumptions, identify gaps in visibility, and shape the work that follows.\nWhat You Will Do\nDevelop threat models for enterprise AI systems and agent-mediated activity, including delegated access, service and workload identities, cloud agent infrastructure, connectors, and downstream actions.\nInvestigate how AI changes attacker operations, including the speed, scale, sequencing, and coordination of reconnaissance, credential abuse, lateral movement, and data theft.\nRecreate realistic attack and misuse scenarios in controlled environments. Collect evidence, map the observable behavior across identity, cloud, and network, and distinguish confirmed signals from hypotheses.\nAssess existing detection coverage, identify telemetry and attribution gaps, and work with Data Science and Engineering to develop and validate new behavioral detections.\nHelp connect an agent’s actions to the human, application, identity, workload, tool, and resource involved, even when a single log source shows only part of the chain.\nTranslate research into clear findings, attack samples, coverage assessments, and recommendations that Product, Engineering, customer-facing teams, and customers can use.\nStay close to emerging techniques and real incidents, contribute original research, and help Vectra decide which problems warrant further investment.\nWhat Will You Need \nApproximately 5 or more years in security research, detection engineering, incident response, threat hunting, red teaming, or a related field, with evidence of independently led technical investigations.\nStrong understanding of attacker behavior and enterprise identity, including authentication, permissions, tokens, service principals, or workload identities.\nHands-on experience investigating security activity in at least one major cloud platform and the ability to reason across cloud, identity, and network evidence.\nAbility to build repeatable labs or simulations, analyze logs and telemetry, and turn findings into detection requirements or coverage tests.\nProgramming or scripting ability, such as Python, for research, data analysis, or test automation.\nClear technical writing and the judgment to explain what the evidence shows, what remains uncertain, and why it matters to customers.\nAbility to work closely with researchers, data scientists, engineers, and product teams in a fast-changing problem space.\nWhat Will Help You\nResearch or operational experience with AI agents, copilots, model services, agent frameworks, tool integrations, or AI-related incidents.\nFamiliarity with attacks involving delegated authority, OAuth applications, cloud control planes, prompt injection consequences, or compromised agent infrastructure.\nExperience correlating activity across multiple data sources or measuring detection efficacy against realistic attack sequences.\nPublished research, open-source tools, conference talks, or other contributions to the security community.\nOur competitive total rewards package includes cash compensation within the range provided below. Actual pay for this position may vary based on the hired candidate’s location, experience and relevant incumbent pay position. \nVectra Total Rewards\n$150,000—$230,000 USD\nVectra provides a comprehensive total rewards package that supportsthe financial, physical, mental and overall health of our employees and their families. Compensation includes competitive base pay, incentive plan eligibility, and participation in the employee equity plan (stock options).
