Staff Information Security Engineer - Threat Detection & Response

Position Overview This senior technical IC role owns Visier’s threat detection and response capabilities end-to-end—driving the overarching strategy, tooling engineering, detection content, and incident response processes. Operating within a high-leverage team, you will scale our security capabilities through advanced engineering and AI, directly safeguarding our multi-cloud platform, corporate identity, and sensitive customer data from sophisticated global threats. Your work will ensure our defensive posture continuously evolves ahead of the threat landscape.

Bring your 8+ years of deep information security expertise, mastery of modern SIEM architectures, and calm incident command experience to a team where you will operate with high autonomy. You will leverage your technical depth to champion engineering-first security practices, safely adopt generative AI workflows, and mentor peers to elevate our collective defense.

What you’ll deliver:

• End-to-End Pipeline Resilience: Design and operate a cohesive detection pipeline spanning multi-cloud, SaaS, identity, and endpoint telemetry to eliminate visibility gaps and ensure comprehensive logging infrastructure.
• Proactive Detection Engineering: Build, test, and tune high-fidelity detections using a modern detection-as-code framework mapped to the MITRE ATT&CK matrix, drastically minimizing false positives while prioritizing critical threat coverage.
• Incident Lifecycle Ownership: Author robust playbooks, runbooks, and escalation criteria that define how Visier handles security incidents, ensuring immediate containment during major events.
• Continuous Defensive Evolution: Lead blameless post-incident reviews and seamlessly translate post-mortem findings into automated detections and architectural hardening requirements.
• Cross-Functional Security Integration: Partner closely with software developers, SREs, and offensive security functions to convert emerging vulnerabilities and organization-specific risks into highly targeted defensive rules.
• AI-Accelerated Operations: Securely integrate and pioneer the use of Generative AI tools to accelerate detection development, alert triage, telemetry enrichment, and automated responses.

What You’ll Bring to the Table

• Education & Experience: 8+ years of hands-on experience in information security, with a proven track record of designing, owning, and scaling threat detection architectures or major incident response programs.
• Detection-as-Code Mastery: Expert-level detection engineering skills utilizing modern SIEM environments (Splunk Enterprise Security preferred) alongside fluent structural mapping to the MITRE ATT&CK framework.
• Cloud & Infrastructure Fluency: Deep technical experience analyzing and building threat coverages across enterprise multi-cloud environments (AWS, Azure, or GCP), core identity providers, and endpoint/EDR telemetry.
• Incident Command Presence: Proven experience acting as an Incident Commander, successfully steering cross-functional technical teams through high-pressure, complex, and high-visibility security incidents.
• Security Automation & Scripting: Strong hands-on coding proficiency (Python, Go, or Bash) to build resilient automation pipelines, data enrichments, and automated response playbooks.
• Strategic Communication: Exceptional ability to translate deeply technical indicators of compromise and complex security risks into clear, high-level business insights for executive stakeholders.
