Program Analyst Three Jobs in Indiana (NOW HIRING)

What You Will Do

The Cybersecurity Analyst III at EXOS CYBER is the senior technical escalation point of the SOC ? the final analyst-tier authority on the hardest, most ambiguous investigations before a case moves into engineering. When Tier 2 has driven an alert as far as standard playbooks and queries allow and still doesn't have a confident answer, it comes to you. You own confirmed, significant incidents end to end across our client environments. You will support day-to-day security operations for our clients with a primary focus on advanced detection, incident response, and threat hunting, working alongside our Cybersecurity Engineers, and Team Lead.

Beyond the queue, you set the bar for investigation quality across the SOC. You QA escalations, mentor and develop Tier 1 and Tier 2, build out the investigation curriculum, and partner with engineering on detection strategy at the program level, not just one noisy rule at a time. This is a hands-on, deeply technical role designed for analysts with 5+ years of experience (or 2+ years past Tier 2) who are ready to operate as the senior individual contributor in a real-world MSSP detection-and-response practice spanning across a diverse client environments.

• Serve as the Tier 3 technical escalation point in the SOC. Take the incidents that Tier 2 cannot fully resolve, drive them to a definitive answer, and hand only genuinely engineering-scoped or architecture-level problems to the Cybersecurity Engineers and Team Lead with a clear, evidence-backed recommendation and a proposed course of action.
• Lead confirmed true-positive incidents end to end across client environments including but not limited to ransomware, business email compromise, account takeover, lateral movement, and data exfiltration including scoping and impact assessment, containment orchestration via SentinelOne, account isolation and credential rotation in Entra ID, eradication and recovery guidance, evidence preservation, root-cause analysis, and client communication through resolution.
• Own and run the proactive threat hunting program: develop hypothesis-driven hunts across the client base using various queries, EDR telemetry, and indicators from CTI feeds; document findings; and feed confirmed patterns back into detection engineering as durable, reusable detections.
• Perform host, memory, and network forensics (Velociraptor, endpoint and identity artifacts, timeline reconstruction) to establish what happened, when, and how far it went, and to support breach-notification and legal/insurance coordination when an incident warrants it.
• Conduct phishing triage and support email-based threat investigations, including user impact assessment and remediation steps.
• Partner with the Cybersecurity Engineers and AI Automation Engineer on detection strategy at the program level coverage and gap analysis against MITRE ATT&CK, detection content design, and false-positive reduction across the fleet rather than one-off alert tuning.
• Apply offensive and adversary-emulation knowledge to inform detection coverage, and support purple team and adversary-emulation exercises by translating attacker TTPs into detections and validating that controls fire as expected.
• Analyze endpoint, identity, and network telemetry to identify suspicious activity, lateral movement, and persistence, and lead phishing and email-based threat investigations through full user-impact assessment and remediation.
• Set and enforce investigation quality standards: QA Tier 1 and Tier 2 escalations and case documentation, run walk-throughs of significant investigations, give kind and direct feedback, and own the Tier 1/Tier 2 onboarding and skills-development curri
• Author the analytical narrative for the most complex client deliverables, post-incident reports, after-action reviews, and the senior-analyst portion of monthly client reporting covering what we saw, what it means, and what we recommend, in language a client technical stakeholder can act on.
• Drive SOC operational maturity by shaping runbook and playbook architecture, investigation checklists, and repeatable workflows, and by mentoring the team toward consistent, defensible outcomes
