Senior Software Engineer - Security

Accountabilities: • Design, develop, and maintain processes for building and managing hardened container base images for development and production environments, minimizing attack surfaces and strengthening overall security.

• Provide hands-on engineering support for securing Kubernetes clusters and containerized workloads, including runtime security, network policies, and admission controllers.

• Strengthen the end-to-end software and infrastructure supply chain by securing CI/CD tools, Infrastructure as Code (IaC) templates, container base images, Helm charts, and third-party dependencies.

• Develop, implement, and continuously improve security automation solutions, including custom tools and scripts that streamline security operations and vulnerability remediation.

• Identify, assess, and triage vulnerabilities discovered through application security reviews, internal penetration testing, Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Software Composition Analysis (SCA).

• Lead vulnerability prioritization and remediation initiatives in collaboration with engineering teams, ensuring risks are addressed effectively and within appropriate timelines.

• Develop, review, and commit code patches to remediate security vulnerabilities, particularly those affecting third-party and open-source software dependencies.

• Contribute to AI-driven security engineering initiatives, exploring the use of machine learning, large language models (LLMs), and Model Context Protocol (MCP) techniques for automated vulnerability remediation and intelligent security alert grouping.

• Promote security engineering best practices across development and infrastructure teams, helping improve the overall security posture of cloud-native environments.

Requirements:

• Bachelor's degree or post-secondary qualification in Computer Science, Information Security, Software Engineering, or a related discipline, or equivalent practical experience.

• Extensive hands-on experience in container security, including designing, implementing, and maintaining hardened container images and securing Kubernetes clusters.

• Strong practical knowledge of Kubernetes and containerized environments, including workload protection, runtime security, network policies, and admission control mechanisms.

• Experience with Infrastructure as Code (IaC) tools, particularly Terraform, for provisioning infrastructure and implementing security controls.

• Proven experience developing and operating security automation solutions, with strong programming skills in Go and/or Python.

• Advanced expertise with GitHub and CI/CD platforms such as GitHub Actions and Jenkins, including their architecture, configuration, and security engineering practices.

• Expert-level proficiency in Software Composition Analysis (SCA), with demonstrated experience identifying and remediating third-party and open-source dependency vulnerabilities at scale.

• Direct experience or strong conceptual understanding of applying AI, machine learning, large language models (LLMs), or MCP techniques to cybersecurity challenges, including automated vulnerability fixing and intelligent alert management.

• Strong familiarity with cloud platforms, particularly AWS and Azure, including their security services and container orchestration capabilities.

• Excellent problem-solving and analytical skills, with the ability to investigate complex security issues and develop practical engineering solutions.

• Strong collaboration and communication skills, with the ability to work effectively with security specialists, software engineers, and cross-functional stakeholders.

• Ability to take ownership of technical initiatives, manage priorities independently, and deliver high-quality solutions in a fast-paced engineering environment.

Nice to Have:

• Experience working with Artifactory/JFrog and related software artifact management solutions.

• Advanced knowledge of application security principles and the OWASP Top 10.

• Familiarity with software supply chain security frameworks and standards such as SLSA.

• Experience implementing scalable security automation and vulnerability management practices within large engineering environments.

Benefits:

• Competitive hourly contract rate of CAD 65–70/hour (T4) , as specified in the original compensation details.

• Fully remote working arrangement, with the role based in Toronto, Canada.

• Full-time contract opportunity with a workload of approximately 40 hours per week.

• Initial contract duration of 5+ months.

• Opportunity to work on strategic security engineering initiatives with significant technical impact.

• Exposure to advanced cloud-native security technologies, container security, Kubernetes, and infrastructure automation.

• Opportunity to contribute to emerging AI/ML/LLM-driven cybersecurity solutions.

• Hands-on experience addressing complex infrastructure and software supply chain security challenges.

• Collaborative and inclusive working environment that values diversity and equal opportunities.
