A place where you can take your career in the direction you want to grow and go

The Opportunity:

Serve as a senior security professional and trusted advisor responsible for protecting the organization's technology environment through effective security operations, incident response, vulnerability management, and network security practices. You will play a key role in identifying, investigating, and mitigating cyber threats while partnering with technology and business teams to implement secure, business-aligned solutions. This role requires deep technical expertise across security operations, network security technologies, and security monitoring capabilities.

Responsibilities:

Serve as a senior technical consultant, ensuring security controls, system designs, and technology implementations align with business objectives, architectural standards, and security requirements.
Lead the investigation, analysis, containment, and remediation of complex security incidents and emerging threats.
Monitor and safeguard network and security infrastructure by analyzing security events, network traffic, threat intelligence, and suspicious activity to identify potential security risks.
Perform advanced threat hunting and security investigations to proactively identify malicious activity and strengthen detection capabilities.
Design, implement, maintain, and optimize network security controls, including firewalls, web application firewalls (WAF), proxy solutions, and related security technologies.
Lead vulnerability management activities, including vulnerability analysis, risk prioritization, remediation recommendations, and validation of corrective actions.
Conduct risk evaluations for infrastructure, applications, cloud services, and technology projects.
Collaborate with stakeholders to define business and technical requirements and translate them into secure, practical solutions.
Participate in security projects and initiatives, ensuring security requirements are incorporated throughout implementation and delivery.
Develop and enhance security monitoring use cases, detection logic, and operational processes to improve threat detection and response effectiveness.
Stay current on emerging threats, attack techniques, vulnerabilities, and security technologies, applying industry knowledge to strengthen the organization's security posture.

Education:

Bachelor’s degree in computer science, Information Security, Cybersecurity, or a related discipline. Equivalent combination of education and experience may be considered.
Typically requires 5-8 years of experience in cybersecurity, information security, security operations, network security, or related disciplines.
Industry recognized certifications such as CISSP, GCIH.

Requirements:

Advanced knowledge of the NIST Cybersecurity Framework, OWASP, CIS Controls, and industry security best practices.
Extensive experience in incident response, including investigation, containment, remediation, and post-incident analysis.
Strong experience with vulnerability management processes, tools, and remediation practices.
Hands-on expertise managing and supporting network security technologies, including firewalls, WAFs, proxies, IDS/IPS, and network detection technologies.
Experience working with SIEM, EDR/XDR, email security, vulnerability management platforms, and other enterprise security solutions.
Strong understanding of network protocols, routing, segmentation, ports, packet analysis, and network traffic investigation.
Experience analyzing security events and threat intelligence to identify and respond to cyber threats.
Proven ability to assess security risks, identify control gaps, and recommend practical remediation strategies.
Strong technical troubleshooting and analytical skills with the ability to solve complex security challenges across multiple technologies.
Strong verbal and written communication skills with the ability to communicate security risks and recommendations to technical and non-technical audiences.
Experience with Python, PowerShell, or other scripting languages for automation and security operations is considered an asset.
5-day-per-week, in-office requirement.

Humble. Hungry. Smart. Does this sound like you?

Do others describe you as being a down-to-earth achiever? Someone who thinks outside the box and always strives to do more than what is required? Someone who sees the bigger picture? You sound brilliant to work with!

We Want You To Shine:

We are committed to providing equal opportunities to all applicants. If you require accommodation due to a disability, you will have an opportunity to notify us when scheduling your interview.

Belonging Matters. Because You Do:

We are an equal opportunity employer and encourage applications from all qualified individuals. Our ability to work as one team across Canada, the United States, and the Caribbean is foundational to our success. We show up as our authentic selves each day and create space for one another’s unique contributions.

We respect the diverse cultures, traditions, and perspectives of Indigenous Peoples and seek to achieve equitable partnerships and opportunities with Indigenous communities.

The Fine Print:

Candidates must be legally eligible to work in the country in which they applied. Regrettably, we are unable to sponsor employment visas at this time.

Final candidates will be required to undergo a confidential pre-employment background check, including but not limited to educational, criminal, credit, drug and alcohol, and/or fitness for duty testing.
