Dec 2026 — PRESENT
Senior Technical Support Engineer
Providing advanced technical support for Linux-based hosting environments, web server infrastructure, databases, DNS, SSL/TLS, email services, and website availability. Focused on complex incident troubleshooting, infrastructure diagnostics, service restoration, security investigations, and root cause analysis across hosting environments.
Core Responsibilities
-
Linux System Administration & Troubleshooting
Investigate operating system-level issues involving resource utilization, process management, filesystem permissions, disk space, service failures, and system configuration. Use command-line tools and system logs to identify faults and restore normal operation.
-
Web Server & Hosting Infrastructure
Troubleshoot website availability, HTTP errors, virtual host configuration, document root issues, rewrite rules, permissions, and web server service failures across supported hosting environments. Analyze request behavior and server logs to isolate application, configuration, and infrastructure issues.
-
Performance Analysis & Resource Optimization
Investigate slow-loading websites, elevated CPU usage, memory pressure, excessive processes, disk I/O bottlenecks, and resource-limit issues. Correlate available system metrics and logs to identify potential bottlenecks and recommend corrective actions.
-
Database Administration & Connectivity
Diagnose database connectivity failures, authentication errors, service availability issues, database resource constraints, and application-to-database communication problems. Review relevant logs and configuration to narrow down the cause of database-related incidents.
-
DNS, Domain & Network Troubleshooting
Investigate DNS resolution failures, incorrect records, propagation-related concerns, nameserver configuration, domain connectivity, and routing or reachability issues. Validate records using DNS diagnostic utilities and distinguish resolver, authoritative DNS, and origin server problems.
-
SSL/TLS & Certificate Management
Troubleshoot certificate expiration, hostname mismatches, incomplete certificate chains, HTTPS redirection issues, and certificate deployment errors. Validate certificate details and investigate TLS handshake failures to restore secure website access.
-
Email Infrastructure & Deliverability
Investigate email delivery failures, SMTP authentication issues, mailbox connectivity, mail queue problems, and sending or receiving errors. Examine relevant mail logs and validate SPF, DKIM, and DMARC configurations where applicable to help identify delivery and authentication issues.
-
Security Investigations & Incident Response
Investigate suspicious website behavior, potentially compromised hosting accounts, malicious files, abnormal processes, unauthorized changes, and security-related service disruptions. Follow established incident handling procedures, document findings, and coordinate remediation or escalation when required.
-
Server Migrations & Service Continuity
Assist with hosting migrations involving website files, databases, DNS configurations, SSL certificates, and email services. Validate service functionality after migration, investigate compatibility issues, and help minimize downtime through appropriate checks and change coordination.
-
Incident Management & Root Cause Analysis
Own complex technical investigations through systematic diagnosis, evidence collection, remediation, and verification. Document incident timelines, identify contributing factors, communicate impact and progress, and escalate infrastructure-level issues with actionable diagnostic evidence.
-
Customer Communication & Technical Escalation
Translate complex technical findings into clear, actionable updates for customers and internal teams. Prioritize service-impacting incidents, maintain troubleshooting documentation, and coordinate with relevant engineering or infrastructure teams when issues require elevated access or deeper investigation.
