In this role, you will take on a premier security consulting, risk assessment, and technical governance capacity, specializing in embedding robust security controls and architecture standards across complex technology initiatives.

As a Senior Network Security Specialist, you will bridge the gap between architecture, infrastructure engineering, risk management, and business stakeholders. Operating within a hybrid work model in Toronto, you will evaluate technology risks, review solution designs, and establish enterprise security guardrails to enable the secure adoption of cloud platforms, containerized environments, AI-enabled solutions, and network infrastructures. This position demands a seasoned security authority with extensive expertise in enterprise network architecture, traffic flow analysis, security frameworks, and governance standards who can influence technology decisions and deliver scalable, secure solutions.

Location: Toronto, ON

Assignment Type: Hybrid (3 days per week onsite, 2 days work from home)

Contract Duration: 1-year contract (with potential for extension and conversion)

Advantages

High-Impact Governance: Shape enterprise security standards, guardrails, and risk assessments for major technology programs.
Modern Technology Scope: Guide security design for cloud platforms, Kubernetes, AI solutions, containerized workloads, and APIs.
Balanced Hybrid Model: Enjoy work-life flexibility with a structured schedule of 3 days onsite and 2 days remote.
Potential for Growth: 1-year contract offering strong possibilities for extension and conversion.
Responsibilities
Provide expert security consulting, threat evaluation, and risk assessments across enterprise technology initiatives and project lifecycles.
Review end-to-end solution designs to deliver actionable, risk-based security recommendations aligned with enterprise standards.
Author and maintain technical security standards, baseline requirements, control mappings, STIGs, and implementation guidelines.
Lead security and governance reviews for cloud, hybrid, on-premises, containerized, B2B, and emerging technology ecosystems.
Evaluate and define security controls for Kubernetes, cloud-native architectures, API interfaces, SaaS applications, and AI-enabled tools.
Design and govern network security controls supporting URL filtering, secure remote access, micro-segmentation, B2B connectivity, and Zero Trust principles.
Partner with engineering and architecture teams to integrate standardized security guardrails into deployment workflows.
Drive security governance modernization, automation of compliance checks, and continuous process improvements.
Analyze complex enterprise network traffic flows and evaluate underlying security implications across distributed environments.
Maintain comprehensive documentation for security processes, architectural reviews, and governance decisions.
Collaborate closely with multidisciplinary engineering, infrastructure, business, and cyber risk stakeholders to ensure alignment.

Qualifications

Professional Experience: Minimum 10+ years of dedicated professional experience in enterprise networking and network security.
Network Infrastructure Expertise: Deep knowledge of enterprise network infrastructure, including routers, switches, load balancers, proxies, DNS, and firewalls, with proven ability to analyze complex network traffic flows.
Risk & Governance Mastery: Strong understanding of security governance, enterprise risk management, and security control frameworks.
Security Assessments: Proven track record conducting comprehensive technical security reviews, threat analyses, and technology risk assessments.
Network Security Architecture: In-depth understanding of network security technologies, enterprise security principles, and secure connectivity models.
Education: Post-secondary degree in Computer Science, Information Technology, Cybersecurity, or equivalent practical work experience.

Preferred Technical Assets & Certifications

Certifications: Recognized industry designations such as CISSP, CCSP, or CISM are considered an asset.
Zero Trust & Modern Security: Knowledge of Zero Trust architecture, secure service edge concepts, and modern network segmentation strategies.
Automation & Emerging Tech: Experience with security automation scripts, cloud security tooling, or container security.
Enterprise Background: Prior experience operating within a financial institution, large-scale enterprise, or highly regulated environment is an asset.

Soft Skills & Delivery Attributes

Communication & Influence: Exceptional written and verbal communication skills with the ability to articulate complex security risks clearly to both technical and executive audiences.
Process Documentation: Strong technical writing skills to produce detailed security standards, operational processes, and governance artifacts.
Stakeholder Collaboration: Demonstrated ability to build strong cross-functional relationships and maintain a collaborative team-player mindset.

Only qualified candidates will be contacted for the next steps. We look forward to hearing from you!
