Everything that makes you unique is welcome; join us and let’s build what’s next - together! What you’ll be doing: As a Senior Security Engineer on the Security Operations team, you will design, build, and enhance our technical capabilities for threat detection, investigation, and response. Your role bridges engineering and operations, transforming security challenges into scalable, automated solutions. Your core responsibilities include: SIEM Engineering: Manage our SIEM platform, onboard and normalize log sources, build and maintain parsers, and ensure high-fidelity data pipelines for detection and investigation. Focus on improving log coverage, data quality, and platform performance. Detection Engineering: Develop and maintain a library of high-quality detections using a Detection as Code approach, managing content through version control, peer review, and automated testing. Align detections with the MITRE ATT&CK framework to enhance coverage, precision, and resilience. SOAR & Automation: Create and maintain automated workflows and playbooks using SOAR platforms to optimize alert triage, enrichment, and response. Identify and automate manual processes within security operations to enhance scalability. AI-Augmented Security Operations: Investigate and implement AI and machine learning to boost security operations, including alert triage, incident response, threat intelligence analysis, and detection content enrichment. Assess emerging AI tools for responsible integration into workflows. Threat Intelligence Integration: Utilize threat intelligence from various sources, integrating indicators and adversary context into detection logic, SOAR playbooks, and hunting activities. Ensure actionable intelligence is timely and structured. Threat Hunting: Conduct proactive, hypothesis-driven threat hunts to uncover attacker activity that bypasses existing detections. Document findings to inform and enhance detection engineering and tools. Incident Response Support: Provide engineering support during security incidents, aiding in investigation, containment, and recovery. Contribute to post-incident reviews, translating lessons into improved detections and playbooks. What you’ll bring to the role: We seek a technically proficient security professional with hands-on experience in security capabilities within complex environments. The ideal candidate will have: Technical Security Experience: Extensive experience in security engineering, DevSecOps, or a similar role, particularly in securing cloud-native environments and modern application stacks. Detection & Response Skills: Practical experience in developing and tuning SIEM detections, writing threat hunting queries, and engaging in incident response. SecOps Tooling: Proficiency in administering and operating core security tools like SIEM platforms (e.g., Splunk, Microsoft Sentinel), EDR/XDR solutions, and vulnerability scanners, with experience integrating these tools for detection and response workflows.
