Data Analyst
Job Description
About the Role
We are looking for a Data Analyst with a strong foundation in network engineering—ideally someone who began their career as a Network Engineer and has since transitioned into a data focused role. This position blends deep technical understanding of networks and firewalls with advanced analytical skills to transform complex log data into actionable insights.
Your background in network infrastructure, routing, switching, and firewall operations will enable you to interpret data with context, troubleshoot effectively, and collaborate seamlessly with engineering and security teams.
Key Responsibilities
Network & Firewall Data Analysis
• Analyze firewall logs, network traffic, and security events to identify anomalies, trends, and potential risks.
• Apply your network engineering knowledge to interpret patterns related to routing, NAT, ACLs, and firewall rule behavior.
• Investigate spikes in blocked traffic, unusual outbound connections, repeated failed attempts, and other suspicious activity.
• Support troubleshooting by correlating network performance issues with firewall or routing data.
Reporting & Visualization
• Build dashboards and automated reports covering:
o Allowed vs. denied traffic
o Top source/destination IPs
o Threat categories
o Bandwidth usage
o Policy hit counts
• Present findings to both technical and non technical stakeholders.
• Develop KPIs and reporting frameworks to support ongoing monitoring and compliance.
Data Processing & Tooling
• Clean, normalize, and transform large volumes of log data from multiple sources.
• Use SQL, Python, or similar tools to automate data extraction and analysis.
• Work with SIEM platforms (Splunk, Sentinel, QRadar, Elastic, etc.) to build queries, alerts, and dashboards.
• Collaborate with engineering teams to improve data quality and logging standards.
Cross Functional Collaboration
• Partner with network and security teams to validate findings and support incident investigations.
• Provide data driven insights to improve firewall rules, network policies, and operational processes.
• Communicate complex technical issues in a clear, concise manner.
Required Qualifications
• 3+ years of experience as a Network Engineer, followed by experience as a Data Analyst or Security Analyst.
• Strong understanding of networking fundamentals (TCP/IP, NAT, routing, ports, protocols).
• Hands on experience analyzing firewall logs and network traffic.
• Proficiency in SQL and at least one scripting language (Python preferred).
• Experience with SIEM tools (Splunk, Sentinel, Elastic, etc.).
• Ability to interpret large datasets and identify anomalies or trends.
• Strong communication skills and the ability to translate technical findings into business insights.
Preferred Qualifications
• Experience with firewall platforms such as Palo Alto, Fortinet, Cisco ASA, or Check Point.
• Familiarity with cybersecurity frameworks (NIST, MITRE ATT&CK).
• Experience building automated dashboards (Power BI, Tableau, Splunk dashboards).
• Background in incident response or threat analysis.
