Harbor IT is seeking a seasoned Incident Commander to lead client security incidents across Microsoft 365, Entra ID, endpoints and networks.

You’ll build and maintain IR playbooks, severity models, escalation matrices, and client-facing reports, plus run tabletop exercises to stress-test responses.

Formación

• 6+ years in cybersecurity with real intrusion response experience.
• Experience leading on security incidents and directing IR teams.
• Experience across multiple organizations (consulting, MSSP, MDR, or DFIR panel).
• Ability to translate technical findings into actionable decisions for executives.

Responsabilidades

• Serve as incident commander for client security incidents: establish scope, priorities, and actions.
• Coordinate triage, investigation, containment, and escalation with Harbor teams and client contacts.
• Develop and defend escalation decisions and post-incident reports.
• Build and maintain incident response playbooks, severity models, and client-facing reports.
• Run tabletop exercises to test and improve playbooks.

Descripción del empleo

This is a new role, and it exists because Harbor manages the systems attackers land in: email, identity, endpoints, servers, firewalls, backups, and the help desk that touches all of them. When a client is compromised we are the first call and the only party with hands already on the environment, but Harbor does not perform deep digital forensics and does not intend to. You will own the first hours instead: triage, scoping, containment decisions, straight answers for executives, and the judgment call about what Harbor handles end to end versus what gets handed to an outside DFIR firm, breach counsel, or an insurance panel. You are the incident commander, directing Harbor’s SOC analysts, security engineers, infrastructure teams, and help desk during a live event, and you will build the practice that supports it: the severity model, the playbooks, the escalation matrix, the client-facing report format, and the tabletops that test all of it before a real incident does. You report to the Senior Director of Cyber Services and work alongside the SOC Manager, the Director of Deployments and Engineering, Client Success, and the account teams who own the client relationship.

Key Responsibilities

Incident Command

Serve as incident commander for client security incidents: establish scope, set response priorities, assign actions to named owners, track decisions, and keep the incident moving when the environment is unfamiliar and the data is incomplete.

Run triage and initial investigation across the environments Harbor manages, including Microsoft 365 and Entra ID, Active Directory, endpoints under EDR, servers, firewalls, and the Sagan-based detection pipeline and its alert history. Often times delegating information gathering to internal resources while you focus on the things only you are capable of.

Own containment decisions and their consequences: what gets isolated, what credentials get reset, what gets left running to preserve evidence, and who at the client has authority to approve each one.

Make and defend the escalation call. Own the incidents that sit inside Harbor’s scope from detection through post-incident reporting, including business email compromise, single-host malware, and bounded credential compromise. When an incident exceeds that scope, brief the receiving DFIR firm and hand off with a written timeline and evidence inventory rather than a phone call and a shrug.

Carry on-call responsibility. Incidents do not respect business hours, and this role requires availability outside them.

Stakeholder Communication

Be the voice clients hear during the worst week of their year. Translate technical findings into decisions an owner, executive, or general counsel can act on, without overstating certainty and without hiding behind jargon.

Coordinate with breach counsel, cyber insurance carriers and their panel firms, third-party DFIR teams, client internal IT, and law enforcement where applicable, and keep Client Success and leadership current on active incidents.

Produce the post-incident report: what happened, what was confirmed versus assumed, what was contained, what remains open, and what the client should change.

Building the Practice

Write and maintain Harbor’s incident response playbooks, severity model, and escalation matrix, and define in writing where Harbor’s responsibility begins and ends so the boundary holds up in a contract and under pressure.

Build named working relationships with outside DFIR firms and breach counsel practices so handoffs start warm instead of starting with introductions.

Maintain an escalation-readiness record for every managed client: who holds an IR retainer, who holds cyber insurance and with which carrier, who has named counsel, and who has nothing.

(When applicable/feasible) Run tabletop exercises with Harbor teams and with clients, and turn what breaks in those exercises into playbook changes.

Mentor SOC analysts and security engineers on investigative method and incident discipline, and feed lessons from real incidents back to detection engineering so the same intrusion gets caught earlier next time.

Required Qualifications & Skills

Experience & Education

6+ years in cybersecurity, with substantial time spent responding to real intrusions rather than monitoring for them.

Direct experience acting as the lead on security incidents, meaning you set the direction and other people executed against it. Participation on an IR team is not the same thing.

Experience responding across multiple distinct organizations, whether from a consulting, MSSP, MDR, or panel DFIR background. This role sees a different environment every time.

Technical Depth

Hands-on investigative depth in Microsoft 365, Google Workspace, and Entra ID compromise: unified audit log analysis, message trace, mailbox rules and forwarding, OAuth consent and application grants, device code and token abuse, and conditional access gaps.

Working command of endpoint detection and response tooling for investigation and containment, and enough host and Windows internals knowledge to interpret process lineage, persistence mechanisms, and lateral movement evidence.

Ability to build a defensible incident timeline from mixed and incomplete sources: SIEM and detection alerts, endpoint telemetry, cloud audit logs, firewall logs, and help desk tickets.

Practical understanding of ransomware and hands-on-keyboard intrusion tradecraft, sufficient to scope an incident correctly and to recognize immediately when it exceeds what Harbor should be handling.

Judgment & Communication

Demonstrated experience working alongside breach counsel, cyber insurance carriers, or third-party DFIR firms during a live incident, including handing off an investigation.

Ability to brief non-technical executives under pressure and to write clearly enough that a client can act on the document without a follow-up call.

Willingness and ability to be reachable outside business hours for incident escalation.

Preferred Qualifications & Skills

GCIH, GCFA, GCIA, or comparable GIAC certification. CISSP or CISM.

Prior experience at a panel DFIR firm, MDR provider, or MSSP incident response team.

Host and memory forensics depth, malware triage, or reverse engineering. Not required for this role, but useful for knowing what to ask an outside firm for.

Linux investigation experience, and cloud incident response beyond Microsoft such as AWS or Google Workspace.

Familiarity with regulatory and contractual notification obligations under HIPAA, PCI DSS, GLBA, state breach notification statutes, or SEC disclosure rules.

Background in managed services or another multi-tenant environment where you owned the relationship as well as the investigation.

Location & Work Model

Location: Remote (US)

Travel: None expected

Schedule: Standard business hours with on-call rotation and availability for incident escalation outside those hours.

Compensation & Benefits

Base salary: $105,000 to $135,000, depending on experience

Employer-paid medical, dental, and vision coverage for the employee, with additional premium plan options available

401(k) with company match

Paid time off

Reimbursement for approved tuition, certifications, and conference attendance
