Requirements

5+ years of hands-on experience in security operations, detection engineering, incident response, threat hunting, or similar fields (or equivalent combination)
Deep knowledge of adversarial tactics, techniques, and procedures (TTPs), threat actor behavior, kill-chain or MITRE ATT&CK framework
Proven experience building detections from scratch (versus just tuning commercial alerts)—i.e. you can turn a hypothesis or a threat intel indicator into a production-quality detection with low false positive rate
Hands-on experience with SIEM or log analytics platforms (e.g. Elasticsearch, Splunk, Datadog, AWS Athena, OpenSearch or equivalent), and alerting/monitoring tooling
Proficiency with a programming or scripting language (e.g. Python, Go, or similar along with IaC - Terraform, Ansible) to build detections

Responsibilities

Lead end-to-end development of detection logic: from threat modeling and hypothesis to writing, testing, tuning, and deploying detection rules and alerts (across logs, telemetry, host, network, cloud)
Build detection pipelines, orchestration, triage logic, and automation for alert handling and response (e.g. SOAR, playbooks)
Conduct threat hunts proactively in corporate and production environments, discovering anomalies and attacker behaviors before they escalate
Lead incident response: investigate, contain, remediate, and perform root cause analysis. Drive post-incident reviews and feed lessons learned back into detection strategy
Assess and fill gaps in visibility—work with engineering teams to ensure logging, instrumentation, and context are sufficient to detect relevant threats
Evolve detection maturity: turn simple signature-based alerts into more advanced behavioral, statistical, ML-driven, and adversary-informed detections, in line with detection engineering maturity models
Author and maintain detection documentation, runbooks, alert definitions, tuning guidelines, and metrics
Collaborate cross-functionally (Engineering, Product, Fraud, Privacy and Legal) to align detection and response work with product lifecycles and system architecture
Be part of on-call rotations or threat-response rotations; escalate, coordinate, and remove blockers during high-severity events
Stay up to date on attacker techniques (MITRE ATT&CK, red team reports, threat intel) and propose new detection patterns or responses accordingly
Participate in hiring, interview evaluation of Security and Infrastructure engineering candidates, and team growth
