Role

Technical Lead, Detection Engineer, Brampton, ON

Our Detection Engineering team is embarking on an exciting new journey, focused on building cutting-edge detection capabilities to stay ahead of the rapidly evolving threat landscape. As we shape the future of threat detection across multi-cloud environments we’re looking for talented individuals to help us crafting innovative solutions to protect multi-cloud environments to combat the evolving threat landscape. If you’re eager to tackle complex security challenges and make a real impact, this is the opportunity for you.

What You’ll Do

• Drive the end-to-end design, development, and technical leadership of high-fidelity, scalable detection content across multi-cloud environments (Azure, GCP, OCI etc). Define detection strategy that balances breadth, depth, and precision threat coverage across critical assets while minimizing blind spots and telemetry gaps.
• Provide technical oversight for SIEM infrastructure, ensuring ingestion pipelines are optimized for scale, signal fidelity, and cost efficiency. Collaborate with platform engineering teams to continuously improve data normalization, enrichment, and event routing.
• Define and enforce detection engineering best practices for SIEM rule development, tuning, and lifecycle management. Ensure content aligns with MITRE ATT&CK, threat intelligence, and operational priorities, while maintaining hygiene and performance at scale.
• Engineer robust detections that scale against modern attacker tradecraft—including automated threats, AI-driven TTPs, (LotL) abuse, and emerging post-exploitation behaviors. Champion logic that reduces noise and false positives, enabling actionable signals for downstream response.
• Operationalize threat intel, telemetry patterns, and anomaly baselines into advanced detection content across SIEM / XDR pipelines. Build correlation logic and multi-stage detections to surface APT activity, credential abuse, zero-day exploitation, and lateral movement etc.
• Act as the detection content authority working alongside security & engineering stakeholders - IR, threat intel, and product teams. Mentor a team of detection engineers, providing code-level reviews, logic validation, and cross-domain threat modeling to maintain high-quality and battle-tested detections.
• Own and evolve detection KPIs (e.g., precision, recall, MTTD, FPR). Implement automated validation and regression pipelines to continuously assess detection health, adapt logic to threat shifts, and ensure long-term signal resilience under active adversary conditions.
