Senior Security Engineer, Infrastructure
Job Description
Team: IT
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Security Engineer, Infrastructure based in Canada.
This role sits at the core of securing large-scale cloud, product, and AI infrastructure in a fast-paced, highly distributed engineering environment. You will be responsible for identifying systemic security risks across platforms and designing scalable remediation strategies that improve engineering-wide resilience. The position blends hands-on security engineering, deep technical analysis, and cross-functional collaboration with product and infrastructure teams. You will help shape secure-by-design practices, enabling engineering teams to ship safely and efficiently at scale. Beyond detection and mitigation, you will build tooling and frameworks that reduce entire classes of vulnerabilities. This is a high-impact role where your work directly strengthens the security posture of complex, modern systems used at massive scale.
Accountabilities:
- Identify, assess, and prioritize business-critical security risks across cloud infrastructure, product surfaces, and AI systems.
- Design and implement remediation strategies with clear, actionable roadmaps to reduce systemic vulnerabilities.
- Develop scalable internal security tooling and frameworks that promote secure engineering practices.
- Conduct deep code reviews, architecture reviews, and threat modeling across distributed systems.
- Drive organization-wide security improvements through collaboration with engineering and product teams.
- Establish and evolve secure engineering patterns, policies, and best practices.
- Mentor engineers and contribute to building a strong security-first engineering culture.
- 5+ years of experience in Security Engineering, Application Security, or Offensive Security roles.
- 3+ years of experience conducting code reviews and security-focused design reviews.
- Strong programming ability in at least one production language (Python, Go, or TypeScript).
- Hands-on experience with Infrastructure-as-Code tools such as Terraform, CloudFormation, or equivalent.
- Strong understanding of common security vulnerabilities, threat modeling, and mitigation strategies.
- Experience working with SaaS architectures, distributed systems, and cloud environments.
- Familiarity with variant analysis, root cause analysis, or secure development frameworks.
- Preferred: experience with policy-as-code (OPA/Rego, Sentinel), CSPM tools (e.g., Wiz, Prisma), or security research contributions.
- Competitive base salary ranging from approximately CAD $196,000 to $207,000 annually.
- Equity grants at hire and ongoing annual refresh grants.
- Fully remote-first work model with flexibility across eligible Canadian provinces.
- Comprehensive health, dental, and wellness benefits.
- Strong focus on work-life balance and flexible working arrangements.
- Opportunity to work on large-scale, high-impact security challenges in modern infrastructure environments.
- Inclusive, collaborative engineering culture with strong emphasis on learning and technical growth.
- Employee programs supporting continuous development and career progression.
