**What You Need To Know** Help build the next generation of cyber resilience at the Bank. Join the Bank’s Cyber Security team to work on high-priority technical initiatives that strengthen how we detect, respond to, and recover from cyber threats in a rapidly evolving environment.

For this role you will be part of the Cyber Security Operations team within the Monitoring and Response portfolio in our Information Technology Services Department. The Cyber Security Operations team is a high-functioning group with a strong focus on building monitoring and analysis capabilities, integration, automation, and delivering value to clients quickly and iteratively.

The team is responsible for detecting and responding to external and internal cyber threats that impact the business functions of the Bank of Canada.

**What You Will Do** You don’t just write detection rules, you build detection systems. You treat detections as code: version-controlled, pipeline-tested, and continuously validated against real adversary behavior. You design and deploy infrastructure as code solutions to create repeatable testing environments, integrate AI-driven workflows to scale detection capabilities, and build the APIs and automation that enable the Security Operations team to respond faster and more effectively.

Your contribution is crucial as we continue to mature our threat detection and response capabilities using modern engineering practices.

More Specifically You Will: Detection Engineering & Validation:

• Develop and optimize detection rules using detection-as-code practices
• Automate testing and deployment of detections via CI/CD pipelines
• Validate detections through simulated attack scenarios (purple teaming)
• Implement automated testing to ensure accuracy and minimize false alerts

Infrastructure As Code & Lab Environnements:

• Build and maintain scalable lab environments using infrastructure-as-code (e.g., Terraform)
• Deploy and manage containerized detection tools and testing frameworks
• Automate provisioning of infrastructure for SIEM integrations, telemetry pipelines, and sandbox environments

AI-Driven Detection & Automation:

• Integrate AI and machine learning to enhance detection logic, automate analysis, and enrich threat intelligence
• Experiment with and implement agentic AI frameworks (e.g., MCP) to enable intelligent, adaptive detection and response workflows
• Leverage AI-assisted coding and automation tools to accelerate development while maintaining strong engineering and security practices

SIEM, API Integration & Platform Engineering:

• Build integrations and optimize security platforms (e.g., Splunk, Elastic, Microsoft Sentinel, EDR tools)
• Design and implement APIs and data pipelines to connect detection, orchestration, and threat intelligence systems
• Develop dashboards, reports, and automation scripts (Python, PowerShell, Bash) to enhance visibility and streamline analyst workflows
• Contribute to sprint goals and collaborate with the team through agile practices (e.g., daily scrums)
• Document solutions and processes, and support knowledge sharing within the team
• Partner with the t…
