If you are looking for meaningful work, smart teammates, and the opportunity to make a real impact in a high-growth company that is redefining security operations, Arctic Wolf is the right place for you.

Our mission is simple: End Cyber Risk.

We are looking for a Threat Researcher - Cloud & Endpoint Detection to join our Integrations Team and help achieve this mission.

You'll be working as a Detection Engineer within Integrations, Detection, & Response (IDR), reporting directly to the Manager of Detection Engineering, XDR while working closely with Pipeline, Platform, Threat Enablement, and Artificial Intelligence teams.

This individual will be responsible for providing technical direction to deliver high-value, performant, generalized detections across many telemetry sources — endpoint, network, cloud, identity, and email — to provide broad Extended Detection and Response (XDR) coverage for customers. They will provide technical guidance and direction to developers through the design, implementation, testing, and tuning of detection content at scale.

This role sits at the intersection of security research, detection engineering, and integrations. The primary responsibility is to analyse data ingested from integrated security providers and transform that telemetry into actionable detection rules, correlation logic, and attack coverage. Initially, the role will focus heavily on detections powered by data from third-party integrations, with opportunities to expand coverage across cloud, identity, endpoint, and Software as a Service (SaaS) ecosystems as new integrations are onboarded.

The ideal candidate has a strong understanding of attacker behaviour, security telemetry, and detection engineering, with the ability to quickly learn new vendor schemas, Application Programming Interfaces (APIs), and event models to identify meaningful detection opportunities.

IN THIS ROLE, YOU WILL:

Third-Party Integration Detection Development

• Serve as a detection subject matter expert within the Integrations Team.
• Apply broad expertise and knowledge across multiple telemetry domains, including endpoint, network, cloud, identity, and email, to design detections that generalize across diverse customer environments.
• Contribute to the development of detection strategies and principles to achieve coverage goals in creative and effective ways.
• Produce detection specifications and coverage models and determine operational feasibility.
• Develop detections, correlation rules, and analytics based on telemetry ingested from third-party integrations.
• Analyse vendor APIs, audit logs, alerts, and event schemas to identify security detection opportunities.
• Design detection coverage that leverages data from integrated security products, cloud providers, identity platforms, email security solutions, and endpoint security tools.
• Partner closely with integration engineers to understand newly onboarded data sources and maximize security value from collected telemetry.
• Provide technical guidance and direction to developers through the design, implementation, testing, and tuning of detection content at scale.

Detection Research

• Research emerging threats, attack techniques, and adversary tactics.
• Work on significant and unique detection challenges where analysis of attacker behaviour requires evaluation of complex, cross-domain signal correlation.
• Apply conceptual thinking to understand advanced threats, novel attack chains, and their implications across telemetry boundaries.
• Identify opportunities to detect malicious activity using third-party security and SaaS telemetry.
• Map detections to the MITRE ATT&CK framework and maintain alignment with evolving threat landscapes.
• Continuously improve existing detections by reducing false positives and increasing attack coverage.
• Exercise independent judgment in detection methodology, technique selection, and evaluation criteria for measuring detection efficacy.
• Provide thought leadership on cross-telemetry detection approaches and contribute to broader organizational projects requiring an understanding of the wider XDR ecosystem.
