Job description

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.

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; escalate 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 environments
• Support 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
• Meet all key performance indicators and notify the SOC Manager promptly when workload or circumstances place a KPI at risk
• Recognize when an assignment should be escalated and escalation without delay
• Support peers across both shifts and contribute to a collaborative, accountable team culture
• Perform other duties as assigned

Success Metrics

• Mean time to acknowledge and mean time to respond for alerts during the assigned shift
• Mean time to contain and mean time to resolve for confirmed incidents
• KPI adherence across all assigned tickets
• Escalation accuracy: incidents escalated at the appropriate severity and stage, with complete supporting documentation
• Quality of shift handoffs, measured by open items with a clear owner and no unattended investigations at shift change
• Accuracy of automated-action validation and exceptions correctly identified in the overnight automation review
• On-call responsiveness: acknowledgment and response times for overnight escalations during assigned on-call weeks
• 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

• Complete training for and maintain awareness of cybersecurity risks, including insider threat, and the appropriate handling of CUI and other regulated data
• Treat client data and OSIbeyond data as sensitive, and do not disclose, release, or otherwise transfer it outside of OSIbeyond or client environments without written permission
• Follow cybersecurity requirements as described in the Employee Handbook and other OSIbeyond policies
• Immediately follow incident response procedures when a security incident or concern is identified
• Assist with the escorting or monitoring of visitors when working onsite
• Monitor alerts from the SIEM and related security platforms, conduct vulnerability scans, and review and update logged events
