Senior Cybersecurity Analyst

Marathon TS

Senior Cyber Security Analyst

We are seeking a highly capable Senior Cyber Security Analyst who will support the security operation center as part of a distributed enterprise IT team. This role requires a strong technical foundation across hybrid on-premises and cloud infrastructure, a high degree of responsibility, IT security disciplines, and the ability to operate in a fast-paced, compliance-driven environment. Lead and execute advanced security monitoring, incident response, threat hunting, and risk-reduction activities to protect company assets, systems, and information data. Coordinate with cross-functional teams to improve security posture across enterprise.

Key Responsibilities:
  • Security monitoring & detection: Design, tuning, maintain IDS/IPS, SIEM, EDR, and log collection pipelines to detect advanced threats.
  • Incident Response: Establish and implement an operational incident-handling capability for organizational systems, encompassing preparation, detection, forensic collection, analysis, containment, eradication, recovery, user response, and post-incident root-cause analysis. Track and document incidents, produce reports and recommendations, notify relevant authorities, and conduct tests of the organization's incident response capability.
  • Threat hunting & intelligence: Proactively hunt for threats across networks, endpoints, cloud, and applications using threat intelligence, YARA rules, KQL queries, and custom tooling.
  • Vulnerability management: Coordinate regular vulnerability scanning, assess risk, prioritize remediation, and validate fixes.
  • Risk assessment & remediation: Conduct risk assessments, threat modeling, and security reviews for systems, applications, and projects; propose mitigations and track remediation.
  • Security architecture & controls: Advise on secure design and configuration for onpremises infrastructure and cloud (Azure/AWS), network, identity, and application layers; implement security controls and hardening.
  • Automation & tooling: Develop automation (playbooks, SOAR, scripts) to streamline detection, response, and reporting.
  • Compliance & governance: Support audits and regulatory compliance programs (e.g., CMMC, NIST 800-171, DFARS 7012) by providing evidence, mapping controls, and remediation tracking.
  • Metrics & reporting: Define and report key security metrics (MTTD, MTTR, incident counts, vulnerability trends); brief technical and executive stakeholders.
  • Collaboration: Work with Enterprise IT, DevOps, HR, legal, and business units to integrate security into product/programs, change management, and release processes.
Competencies and Traits:
  • Strong problem-solving and investigative mindset.
  • Calm under pressure with decisive incident leadership.
  • Ability to translate technical findings into business risk terms.
  • Proactive, continuous learner who keeps up with threat landscape.
What We Are Expecting From You (i.e. The Qualifications You Must Have):
  • 12+ years of hands-on experience in security operations, incident response, threat hunting, or related roles.
  • Strong knowledge of SIEM or logging platform (e.g., Splunk, Elastic, Sentinel), EDR (e.g., CrowdStrike, Microsoft Defender), and network security tooling.
  • Experience with hybrid on-premises/cloud security environments using AWS/Azure and securing physical systems, virtual machines, and containers.
  • Proficiency with one or more scripting languages (Bash, Python, PowerShell, or Perl) and building detection queries.
  • Solid understanding of TCP/IP, DNS, SSL/TLS, authentication protocols (OAuth, SAML), and common attack vectors.
  • Solid understanding of MITRE Telecommunication&CK framework/Cyber Kill Chain.
  • Familiar with vulnerability scanning tools (Tenable/Nessus, Qualys), and remediation reporting workflows.
  • Familiarity with FedRAMP controls and cloud security frameworks (AWS, Azure, or hybrid on-premises/multi-cloud environments).
  • Incident response and digital forensics experience.
  • Excellent analytical, communication, and stakeholder management skills.
  • Bachelor's degree in Computer Science, Information Security, Cybersecurity, or 7 years equivalent relevant experience (or relevant certifications).
  • Knowledge of DISA STIGS, CIS benchmarks, STIG Viewer, and SCAP Compliance Checker.
Preferred Qualifications:
  • Certifications: Security+, CySA+, CEH, CASP+/SecurityX, CISSP, or equivalent.
  • Experience with SOAR platforms (Palo Alto Networks, Splunk, Elastic).
  • Familiarity with compliance frameworks (CMMC, NIST 800-171, NIST 800-53, DFARS).
  • Prior experience in a SOC, MSSP, or large enterprise environment.
