The Information Security Office partners closely with technology and business teams to protect Purolator’s systems, data, and customers while enabling innovation and secure delivery at scale.

The Senior Application Security Analyst is responsible for embedding security into the software development lifecycle (SDLC) by partnering closely with application and engineering teams. This role focuses on identifying, assessing, and reducing application and API security risk through threat modeling, secure design reviews, vulnerability management, and the operationalization of application security controls.

The successful candidate will act as a subject matter expert for application security, providing hands‑on guidance to development teams while helping mature secure development practices across the enterprise.

Responsibilities

  • Review authentication, authorization, data handling, and integration patterns to ensure secure‑by-design implementations

Secure SDLC & DevSecOps

  • Embed security requirements and controls early in the SDLC (“shift left”) by working directly with development and delivery teams
  • Support the integration and tuning of Static Application Security Testing (SAST), Software Composition Analysis (SCA), secret scanning, Dynamic Application Security Testing (DAST) and other application security tooling within CI/CD pipelines
  • Provide secure coding guidance and recommendations based on OWASP Top 10 and industry best practices
  • Develop and maintain clear, reusable documentation and standardized frameworks to enable consistent adoption of application security practices across teams

Vulnerability & Risk Management

  • Triage and assess application security findings from automated tools, penetration tests, and manual reviews
  • Partner with application teams to prioritize remediation based on risk, exploitability, and business impact

Advisory & Stakeholder Engagement

  • Act as a trusted security advisor to application owners, architects, and developers
  • Contribute to the development and maintenance of application security standards, patterns, and guidance documentation
  • Support third‑party assessments and security reviews for externally developed or hosted applications

Continuous Improvement

  • Identify opportunities to improve application security processes, tooling, and governance
  • Stay current with emerging application security threats, vulnerabilities, and defensive techniques
Required Qualifications
  • Bachelor’s degree in Computer Science, Information Security, or a related field, or equivalent practical experience
  • 5+ years of progressive experience in application security, secure software development, or product security
  • Strong understanding of web and API technologies (HTTP/S, REST, JSON, OAuth, OpenID Connect, SAML)
  • Hands‑on experience with application security testing tools (SAST, SCA, DAST, secret scanning)
  • Solid knowledge of OWASP Top 10, threat modeling methodologies, and secure coding principles
  • Strong analytical, problem‑solving, and communication skills, with the ability to explain security risks to both technical and non‑technical audiences
  • Exceptional interpersonal skills and proven to flourish working in a fast-paced environment.
  • Ability to work effectively in a cross-disciplinary team, across multiple projects and multiple locations.
Additional skills that set you apart
  • Experience securing cloud‑native applications in AWS and/or Azure environments
  • Familiarity with API gateways, WAFs, and runtime protection controls
  • Experience working in agile or DevOps delivery environments
  • Relevant security certifications (e.g., CSSLP, GWAPT, GWEB, CISSP, OSCP)
  • Strong knowledge of one or more modern programming languages (e.g. Python, Java, C++, JavaScript)

The work we do at Purolator impacts every Canadian. To work with us, you must be eligible to obtain a Reliability Security Clearance.
