Expertise with common application security tools and platforms (e.g., Burp Suite, SAST, SCA).

Experience with log aggregation and SIEM technologies.

Ability to identify malicious behaviour and emerging threats via log analysis.

Demonstrated interest in improving your craft by using AI.

Experience with Ruby on Rails, Puppet, Kubernetes, Terraform, ELK (Elastic, Logstash, Kibana).

Strong AWS security experience on EC2 and managed services.

Experience with infrastructure security (WAF, ACLs, authentication, device hardening).

Compensation & Benefits

The expected salary range for this role is CAD $116,500 to $157,500, depending on experience and geographic region.

Competitive, equitable salary with top‑tier health, dental, and vision insurance.
