- Lead technical investigation, containment, and recovery for security incidents alongside IT, engineering, and business teams, and turn root-cause findings into stronger detections, playbooks, and controls.

- Author and tune detections, correlation rules, and queries, drafting them with AI from the threat behaviors you want to catch and validating before they go live.

- Prioritize and drive remediation of vulnerability, pentest, and security-assessment findings across the organization.

- Routinely assess network and cloud security posture and prioritize gaps against best practices.

- Configure and maintain security devices, systems, and tooling according to best practices.

- Investigate and respond to phishing reports and quarantine-release requests.

- Own and enhance JSSI's Security Awareness Training program.

- Design, implement, and operate security improvements across the environment to continually raise the organization's security posture and program maturity.

- Establish and report on key security metrics and respond to audit requests and client due-diligence questionnaires.

- Document and improve operational procedures, runbooks, and SOPs.

- Contribute to incident response planning, security policies, disaster recovery, and business continuity planning.

- Collaborate with other IT professionals to advise on cybersecurity best practices.

- Participate in the on-call rotation and respond to critical security alerts off-hours.

- Hands-on experience building automations and playbooks in a SOAR platform, integrating security tooling via APIs to automate triage, enrichment, and response.

- Knowledge of data privacy and compliance regulations and cybersecurity frameworks such as ISO 27001 and NIST.

- Excellent written and verbal communication skills.

- Detail orientation and strong analytical and problem-solving abilities.
