Job Description
Senior Information Security Analyst

Location: Mississauga, ON (Onsite)Reports to: Team Lead, Information Security
Compensation: $106,000 - $120,000
Role Summary
We are seeking a Senior Information Security Analyst with deep, hands‑on experience across security operations, incident response, and data protection in enterprise, cloud, and SaaS environments.

This role is responsible for defending the organization against advanced cyber threats while leading efforts to protect sensitive business, employee, and executive data across on‑premise systems, cloud platforms, and collaboration tools such as Microsoft 365.

The Senior Analyst operates as a technical authority and trusted advisor, helping shape security detection, response, and data protection practices across the enterprise.

This role goes beyond monitoring tools—it focuses on investigations, risk reduction, and building durable security controls that scale across contemporary hybrid IT and SaaS environments.

This position is fully onsite at our Mississauga, ON office.

What Success Looks Like in This Role
Cyber incidents are detected early across network, endpoint, cloud, and SaaS platforms, investigated thoroughly, and closed decisively

Junior analysts get stronger because of your guidance, not despite it

Recommend pragmatic remediation options, compensating controls, and secure design improvements
Provide hands‑on security architecture guidance for cloud services, SaaS platforms, and identity‑centric solutions when needed
Governance, Risk & Compliance
Contribute to security standards, policies, procedures, and technical guidelines related to cloud security, SaaS usage, identity, and data protection
Perform and review technical risk and threat assessments for critical systems, including cloud‑hosted and SaaS‑based services
Support internal and external audits (e.g., PCI, ISO 27001, regulatory reviews)
Define and track remediation plans through to closure
Tooling, Detection & Continuous Improvement
Improve detection logic, alert quality, and investigation workflows across SIEM, EDR, email security, cloud security, and SaaS telemetry
Evaluate new security tools and capabilities with a practical, outcomes‑focused mindset
Reduce noise, false positives, and manual effort where possible
Stay current on emerging threats targeting cloud platforms, SaaS environments, identity systems, and collaboration tools
Leadership & Mentorship
Act as a technical mentor to junior and intermediate analysts
Lead by example during incidents, investigations, and projects
