Conduct investigations and analysis to identify, contain, and remediate cybersecurity threats and incidents.

Support security assessments, audits, and compliance activities by providing operational security expertise and evidence as required.

Assist in evaluating, implementing, and maintaining security technologies and capabilities to strengthen the organization’s security posture.

Contribute to security awareness and knowledge-sharing initiatives across technology teams and business stakeholders.

Mentor junior team members and provide guidance on security processes, technologies, and best practices.

Participate in on-call and incident response activities as required to support business continuity and operational objectives.

How do we define success for your role?

You understand our client’s industry, challenges, and opportunities; clients describe you as positive, professional, and delivering high-quality work
You identify, recommend, and are focused on effective service delivery to our clients
You share in an inclusive and engaging work environment that develops, retains, and attracts talent
You actively participate in the adoption of digital tools and strategies to drive an innovative workplace
You grow your expertise through learning and professional development

Qualifications & Requirements

Degree in Cybersecurity, Information Technology, Computer Science, Engineering, or a related field, or equivalent education and experience.

5+ years of progressive experience in cybersecurity, with a focus on security operations, incident response, threat detection, or cyber defense.

Strong knowledge of security operations, incident response, threat detection methodologies, and cybersecurity practices.

Experience working with enterprise security technologies supporting monitoring, detection, investigation, and response activities.

Experience investigating security incidents and coordinating remediation activities across technology teams.
