As a Cyber Defense Engineer on our Cyber Defense Operations team, you will serve as a front-line defender responsible for protecting both BeyondTrust’s enterprise infrastructure and the integrity of the products our customers depend on

You will monitor, investigate, and respond to security events in an environment where the stakes are real and the adversaries are capable. You will work alongside experienced threat hunters, incident responders, and detection engineers in a collaborative team that values sharp analytical thinking over checkbox compliance

This team is building toward an AI-augmented operating model. You will be expected to use AI-driven tools in your daily work and to contribute to how we integrate these capabilities into our detection, triage, and response workflows. We are not looking for people who are waiting to be told what to do—we are looking for people who want to build something

Monitor and triage security alerts across SIEM, EDR, and CSPM platforms covering both corporate and product environments

Investigate alerts to determine scope, severity, and whether escalation is warranted

Leverage AI-assisted triage and enrichment tools to accelerate analysis and reduce mean time to detect

Classify, document, and track alerts through the full lifecycle using ticketing and case management systems

Participate in or lead incident response engagements from detection through remediation, including evidence collection, forensic analysis, root cause determination, and stakeholder communication

Conduct investigations across SIEM, EDR, CSPM, and cloud-native log sources including identity provider logs, cloud audit trails, and network flow data—spanning both corporate and product infrastructure

Execute established IR runbooks across identity, endpoint, cloud, and email investigation workflows





Manage or assist with evidence handling, forensic artifact collection, and chain-of-custody procedures

Produce clear, decision-ready incident summaries and post-incident reports for both technical and leadership audiences

Contribute to the design, implementation, and tuning of detection rules across SIEM and EDR platforms, with a focus on reducing false positives and closing coverage gaps

Translate threat intelligence (CVE advisories, CISA alerts, vendor bulletins, open-source feeds) into actionable detection content, with particular attention to threats targeting privileged access tooling and supply chain attack vectors

Help maintain and evolve detection coverage mapped to MITRE ATT&CK;

Partner with threat hunting peers to validate detection logic through hypothesis-driven hunts

Use AI-driven tools for alert triage, enrichment, and investigation as a standard part of daily operations

Contribute to the evaluation, integration, and optimization of AI and automation capabilities across the team’s workflows

Assist in designing prompts, agent workflows, or LLM-based pipelines that augment analyst capabilities and reduce manual effort

Partner with engineering teams to improve log ingestion, data quality, and tool integrations

Maintain daily operational notes and shift handoff documentation

Contribute to and refine IR runbooks, playbooks, and standard operating procedures





Participate in on-call rotation for after-hours incident escalation

Track and report on operational metrics (MTTD, MTTR, MTTC, false positive rate) and identify improvement opportunities

Participate in tabletop exercises, purple team activities, and post-incident reviews

Comfort using AI systems (e.g., LLM-based assistants, copilots, or AI-driven analysis tools) as part of security workflows

4+ years of experience in a SOC, security operations, or incident response role

Understanding of common attack frameworks (MITRE ATT&CK;), network protocols, and endpoint behavior

Solid written communication skills; able to document findings clearly and concisely for both technical and non-technical audiences

Experience with at least one SIEM platform and familiarity with writing search or detection queries

Familiarity with EDR platforms and cloud environments (IaaS preferred)

Experience leading or co-leading complex incident response engagements from triage through remediation

Scripting and automation skills (Python, PowerShell, or equivalent) applied to security workflows

Experience with identity and access management platforms and cloud security posture management tools

Familiarity with SOAR platforms or orchestration tools for automated response and enrichment

Experience designing or implementing AI agent architectures, LLM-based automation pipelines, or prompt engineering for security use cases

Experience building or contributing to threat intelligence programs or detection-as-code pipelines

Understanding of the privileged access management landscape and the threat actors that target it

Track record of evaluating and adopting emerging technologies in a production security environment
