Description du poste

Since 2004, OSIbeyond has delivered managed technology and cybersecurity services on a founding principle: outstanding technical expertise, matched by an exceptional customer experience. Today, that commitment is delivered through OSIbeyond ONE, our integrated technology platform that unifies IT operations, cybersecurity, Microsoft 365, cloud, automation, AI, and expert support into a single, continuously managed environment. The platform is built on a clear operating philosophy: Automation First. AI Enabled. People Powered.

The OSIbeyond Security Operations Center is the cybersecurity engine of that platform. It provides continuous detection, investigation, and response across a diverse portfolio of client environments, including organizations subject to federal compliance frameworks such as CMMC and NIST SP 800-171. The SOC operates on a two-shift, automation-augmented coverage model. Human analysts staff the Day and Evening shifts, and a purpose-built automation layer operates overnight, backed by an on-call analyst, ensuring that every hour of every day is covered by a trained analyst or by an automated response workflow.

The SOC Analyst is the “People Powered” element of security operations. Automation handles the repetitive, high-volume work of enrichment, correlation, and first-response containment, so that the analyst’s time is concentrated on the work that requires human judgment: validating and investigating alerts, leading incident response, advising clients, and continuously improving detection and automation logic. The SOC engineering team is continuously expanding this automation capability, and analysts are expected to contribute to that evolution as active participants rather than passive users.

This position is suited to a technically accomplished security professional who values structure, precision, and accountability. The successful candidate demonstrates sound analytical judgment, disciplined documentation, professionalism in client communication, and a commitment to protecting client environments with the same care they would expect for their own.

ABOUT THE ROLE

The SOC Analyst monitors, analyzes, and responds to cybersecurity threats across client environments. The analyst operates the SOC’s security tooling, investigates suspicious activity, contains and remediates confirmed incidents, and communicates findings clearly to clients and internal stakeholders.

During each shift the analyst owns the live alert queue, triaging detections from the SIEM, endpoint, identity, and email security platforms; determining scope and severity; and executing or authorizing the appropriate response. Because the SOC operates on a shift model, the analyst is also responsible for the integrity of coverage: conducting structured handoffs at the end of each shift, reviewing existing alerts at the start of the Day shift, and ensuring that no detection, investigation, or client commitment is left without a clear owner.

Beyond day-to-day operations, the analyst performs scheduled vulnerability scanning, conducts root cause analysis for security incidents, and identifies repetitive manual work that should be transitioned to automation. Performance is measured against response times, investigation quality, SLA adherence, documentation standards, and contributions to the continuous improvement of detection and automation.

SCHEDULE & SHIFT MODEL

The SOC operates a two-shift model with 12-hour shifts. Each analyst is assigned to a fixed shift (Day or Evening) and does not rotate between shift times. The two shifts overlap for six hours (11:00 AM to 5:00 PM), providing a structured handoff window and dual-analyst coverage during peak business hours. Overnight coverage (11:00 PM to 5:00 AM) is provided by the SOC’s Tines automation layer, which performs enrichment, containment, and escalation according to documented playbooks. Escalations that exceed the automation’s authority are routed to the on-call SOC Analyst.

ESSENTIAL DUTIES & RESPONSIBILITIES

Security Monitoring & Alert Triage (≈50%)

• Monitor client environments continuously for security threats using the SIEM, endpoint detection and response, identity protection, and email security platforms
• Triage inbound alerts by following the automated priority procedure; determine whether each detection represents a true positive, benign activity, or a tuning opportunity
• Respond to alerts where automation is unable to clearly determine legitimacy and/or severity. Work and complete assigned tickets in accordance with documented standard operating procedures and service level commitments
• Identify recurring false positives and submit detection-tuning recommendations to the SOC Manager and automation team

Incident Investigation & Response (≈25%)

• Investigate security incidents including account compromise, business email compromise, social engineering, malware, and ransomware activity
• Through automated means and manual review, analyze servers, workstations, identities, and other assets suspected of compromise and accurately assess the scope and type of the issue
• Contain and remediate confirmed threats using approved automation workflows, scripts, policies, playbooks, and platform controls; accelerate in accordance with the incident response plan when the situation exceeds the analyst’s authority or expertise
• Provide accurate, timely, and professionally written incident communications to designated client points of contact and internal stakeholders with the assistance of the SOC Manager or CISO

Vulnerability Management & Security Posture (≈10%)

• Perform regularly scheduled vulnerability scanning across client environmentsSupport client compliance objectives, including CMMC and NIST SP 800-171 requirements, by producing the monitoring evidence, logs, and reports required by those frameworks
• Contribute to periodic client security reviews with clear, data-supported observations

Automation Oversight & Continuous Improvement (≈15%)

• Review the overnight Tines automation log at the start of the Day shift, confirm low confidence actions were appropriate, and remediate or elevate any exceptions
• While on call, respond to overnight escalations from the automation layer, take ownership of the incident, and document all actions taken for review at the start of the Day shift
• Identify repetitive manual investigation and response steps and submit them to the automation team as candidates for new automations or expanded playbooks
• Identify repetitive “false positives” for the SOC Manager to address
• Test and provide structured feedback on new detections and automation workflows before they are placed into production
• Track and document all work in the ticketing system with detail sufficient for a peer to resume the work without additional context

General Responsibilities

• Provide high-quality written and verbal customer service in every client interaction

• Detection tuning and automation candidates submitted and adopted
• Documentation quality and completeness of ticket notes, incident reports, and root cause analyses
• Client satisfaction with incident communications and security reviews

SECURITY RESPONSIBILITIES
