What is a senior cybersecurity engineer?

Senior Cybersecurity Engineers are experienced professionals responsible for designing, implementing, and managing security measures to protect an organization's computer systems and networks. They lead efforts to identify vulnerabilities, respond to security incidents, and ensure compliance with relevant regulations and standards. In addition to technical skills, they often mentor junior staff, develop security policies, and collaborate with other departments to strengthen overall cybersecurity posture. Their role is critical to safeguarding sensitive data and minimizing risks from cyber threats.

What are the key skills and qualifications needed to thrive as a senior cybersecurity engineer?

A Senior Cybersecurity Engineer typically requires expertise in network security, risk assessment, incident response, and a bachelor's degree in computer science or a related field, often supplemented by several years of relevant experience. Familiarity with security tools such as SIEM solutions, firewalls, IDS/IPS systems, and certifications like CISSP, CISM, or CEH are highly valued. Strong analytical thinking, problem-solving abilities, and excellent communication skills help professionals proactively address threats and collaborate with cross-functional teams. These skills are essential to effectively safeguard organizational assets, ensure compliance, and respond swiftly to security incidents.

What are the typical team collaborations and cross-department interactions for a senior cybersecurity engineer?

As a Senior Cybersecurity Engineer, you’ll regularly collaborate with IT, software development, and risk management teams to ensure security measures are integrated across all systems. You’ll participate in incident response exercises, advise on secure software design, and help educate other departments on cybersecurity best practices. This role often involves leading security projects and mentoring junior engineers, making strong communication and teamwork skills essential for success.

What is the difference between Senior Cybersecurity Engineer vs Cybersecurity Analyst?

AspectSenior Cybersecurity EngineerCybersecurity Analyst
Certifications CISSP, CISA, CEH CompTIA Security+, GIAC Security Essentials
Work EnvironmentDesigning security systems, implementing security measures, leading security projectsMonitoring security alerts, analyzing threats, responding to incidents
Employer & Industry UsageUsed in large organizations, tech firms, finance, governmentCommon across various industries, including healthcare, retail, and finance

While both roles focus on cybersecurity, Senior Cybersecurity Engineers typically design and implement security solutions, whereas Cybersecurity Analysts monitor and respond to security threats. The senior engineer often leads projects and develops security strategies, while analysts focus on threat detection and incident response. Both roles require relevant certifications and are vital in maintaining organizational security.

Job description

Senior Cyber Security Engineer

Wilmington, DE

Monday - Friday 8:00 - 5:00 ET

Hybrid/Remote

We are seeking a Senior Cyber Security Engineer to play a pivotal role in advancing our detection, response, and automation capabilities across a modern enterprise security stack. In this role, you will serve as a hands-on technical leader responsible for designing, engineering, and optimizing Cortex XSIAM to deliver high-fidelity detections, scalable automation, and rapid incident response. You will work with rich telemetry spanning endpoint, network, cloud, and identity data to turn adversary behavior into actionable analytics that measurably reduce risk.

This position is ideal for an experienced detection or security operations engineer who thrives at the intersection of platform engineering and threat expertise. You will collaborate closely with SOC analysts, incident responders, and fellow engineers, influence detection strategy, and mentor others while working on creative solutions that matter at enterprise scale. You'll have the opportunity to shape how security operations evolves, driving improvements in signal quality, automation maturity, and mean time to respond, while continuously expanding your technical depth in XSIAM, XQL, and advanced security analytics.

 Some of the things you'll be doing:

  • Platform Engineering: Design, deploy, and maintain Cortex XSIAM detections, correlations, and analytics across endpoint, network, cloud, and identity data sources. Build and tune detection logic to reduce noise while improving true positive rates. Perform ongoing platform optimization, including ingest management, rule tuning, and performance improvements.
  • Detection Engineering & Threat Hunting: Develop and maintain custom detections using XQL (Cortex Query Language). Conduct proactive threat hunting and investigations using XSIAM analytics and telemetry. Translate threat intelligence and adversary techniques into actionable detections aligned to MITRE ATT&CK.
  • Automation & Response: Design and maintain automated response playbooks to accelerate incident containment and remediation. Integrate XSIAM with enterprise tooling (e.g., identity, EDR, ticketing, cloud, network security platforms). Support continuous improvement of MTTR through automation and orchestration.
  • Operations & Collaboration: Partner with SOC analysts, incident responders, and engineering teams on investigations and response activities. Support post-go-live enhancements, backlog grooming, and technical debt reduction initiatives. Provide technical guidance and mentorship to engineers and analysts.

What technical skills, experience and qualifications do you need?

  • Minimum 5+ years of experience in Security Operations, Detection Engineering, or SIEM/SOAR engineering
  • Hands-on experience with Palo Alto Networks Cortex XSIAM (or strong XDR/XSOAR experience with rapid XSIAM ramp-up)
  • Strong working knowledge of SIEM/XDR concepts and log analytics, incident response and threat detection workflows, and automation and orchestration use cases
  • Proficiency with XQL, KQL, SPL, or similar security query languages
  • Experience integrating data from endpoint, network, cloud, and identity platforms
  • Strong scripting experience (Python preferred)
  • Experience operating security platforms at enterprise scale
  • Preferred experience with endpoint security (Cortex XDR, Defender, CrowdStrike, etc.), cloud security telemetry (AWS, Azure, GCP), identity and access logs (AD, Azure AD, IAM)
  • Familiarity with MITRE ATT&CK and threat intelligence frameworks
  • Experience supporting a 24/7 SOC or global security operations team
  • Bachelor's degree in computer science, information assurance, MIS or equivalent industry experience.
  • Palo Alto Networks Certified XSIAM Engineer or Analyst certification preferred.
  • Additional industry certifications are a plus (i.e., CEH, CISM, etc.)
