About the role

Key responsibilities & impact

Research adversarial techniques and translate threat behaviors into high-fidelity detections aligned to complex cybersecurity use cases.
Design, build, and operate production-grade security detection infrastructure across Google SecOps and internal automation applications that support enrichment, orchestration, and response workflows.
Lead telemetry and detection lifecycles, including source onboarding, parsing, normalization, enrichment, testing, deployment, tuning, and ongoing maintenance.
Develop custom integrations, automations, and lightweight services using application programming interfaces (APIs), webhooks, and event-driven patterns to improve signal fidelity and reduce mean time to detect and mean time to respond.
Create dashboards, metrics, and reports using business intelligence tools, structured query language (SQL), statistical analysis, and applied artificial intelligence and machine learning techniques to improve threat visibility and operational reporting.
Apply Python, prompt-driven workflows, model context protocol (MCP) capabilities, and agent-to-agent orchestration patterns to support detection engineering, enrichment, and analytic decision support.
Collaborate with threat intelligence, threat hunters, incident responders, red team, and engineering partners to evaluate detection coverage gaps and improve defensive capabilities.
Manage work through Agile practices, documenting requirements, tracking delivery, and maintaining reliable platform operations across hybrid environments.

Requirements

What you’ll need

8+ years of experience in cybersecurity engineering, security operations, or detection engineering, including building and maintaining detections for enterprise security environments.
8+ years of experience developing and tuning detections using security information and event management (SIEM) technologies, security orchestration, automation, and response (SOAR) platforms, and correlated rule logic for complex threat scenarios.
8+ years of experience scripting and automation development using Python, SQL, PowerShell, Bash, or similar languages to support integrations, telemetry processing, and response workflows.
8+ years of experience working with cybersecurity technologies such as endpoint detection and response (EDR), intrusion detection system or network detection and response (IDS/NDR), user and entity behavior analytics (UEBA), data loss prevention (DLP), web application firewall (WAF), proxy technologies, and cloud security services.
Experience designing and supporting API integrations using representational state transfer (REST), JavaScript Object Notation (JSON), webhooks, OAuth, service accounts, and event-driven messaging patterns with measurable reliability and observability outcomes.
Experience applying MITRE ATT&CK, detection coverage analysis, telemetry mapping, dashboard development, and threat reporting to improve cyber detection quality and operational awareness.
Bachelor's degree in cybersecurity, computer science, information technology, engineering, or a related field, or equivalent combination of education, related experience and/or military experience.
