Engineering Tech Lead (Product Security)

Accountabilities • Penetration Testing and Security Assessments: Conduct hands-on penetration testing of products and infrastructure to identify and exploit vulnerabilities, with particular focus on Kubernetes environments, container isolation, and cloud-native systems.

• Vulnerability Management: Investigate, triage, prioritize, and remediate security vulnerabilities in application code and dependencies, taking ownership from discovery through patch development, release, and verification.

• Threat Modeling and Secure Design: Review new features and security-sensitive architectural designs early in the development lifecycle, identify potential attack paths, assess risks, and recommend practical mitigations.

• Kubernetes Security: Analyze Kubernetes attack surfaces, including container breakout risks, privilege escalation, role-based access control (RBAC), admission control, and security policy configurations.

• Kubernetes Internals and Infrastructure Security: Apply a strong understanding of Kubernetes components, including the API server, controllers, admission mechanisms, and kubelet, to identify weaknesses and strengthen system security.

• Code and Architecture Reviews: Participate in code reviews, design discussions, and technical reviews to identify security issues and promote robust engineering practices.

• Secure Engineering Practices: Work with engineers across the organization to embed secure defaults, security checks, and threat-aware development practices into the product lifecycle.

• Production Software Development: Build, maintain, and improve production-grade software using Go, contributing directly to secure and reliable infrastructure components.

• Security Communication and Collaboration: Explain vulnerabilities, attack scenarios, and remediation priorities clearly to engineering stakeholders, helping teams make informed security decisions.

• Continuous Security Improvement: Strengthen security processes, vulnerability handling practices, and engineering standards as the platform and its threat landscape evolve.

Requirements

• Hands-on experience conducting penetration tests and identifying and exploiting vulnerabilities in production systems.

• Deep practical expertise in Kubernetes security, particularly container isolation, container breakout scenarios, privilege escalation, RBAC, and security policy best practices.

• Strong understanding of Kubernetes internals, including the API server, admission control, controllers, RBAC, and kubelet.

• Experience building Kubernetes controllers or operators using tools such as controller-runtime, Kubebuilder, or client-go is highly relevant.

• Demonstrated experience with threat modeling, secure system design, and reviewing production architectures for security risks.

• Proven ability to investigate and remediate vulnerabilities in software you work on, including familiarity with the CVE lifecycle, coordinated vulnerability disclosure, and security patch releases.

• Professional experience building and shipping production systems with Go as a primary programming language.

• Strong software engineering fundamentals, including code review, debugging, secure development practices, and practical risk assessment.

• Ability to communicate complex technical risks and security recommendations clearly to engineers and other stakeholders.

• A proactive, independent approach to problem-solving, with the ability to take ownership of security issues and drive them through to resolution.

• A collaborative mindset and commitment to improving security practices across engineering teams.

Nice to have:

• Certified Kubernetes Security Specialist (CKS) certification.

• Experience working at an early-stage startup or in a rapidly growing organization where autonomy, adaptability, and initiative are essential.

• Familiarity with open-source development and cloud-native infrastructure projects.

Benefits

• Competitive compensation: Annual salary for Canada-based candidates ranging from CA$140,000 to CA$200,000, depending on experience and location.

• Equity and bonus opportunities: Compensation package includes equity and a bonus opportunity.

• Premium insurance coverage: Health, dental, vision, and life insurance, with plans for eligible dependents; coverage may vary by country.

• Flexible working schedule: Flexibility to manage your schedule around personal commitments, with an emphasis on results rather than fixed working hours.

• Remote-work flexibility: Remote-first working arrangements with flexibility in where you work.

• Global collaboration: Work with a distributed team of infrastructure engineers on challenging, high-impact technical problems.

• Technical ownership: Opportunity to influence product security, infrastructure architecture, and secure engineering practices.

• Open-source environment: Contribute to a culture that values open-source technology, continuous learning, and innovative approaches to complex engineering challenges.
