Core Responsibilities

Primary Functions

Serve as the first point of contact for technical incidents via phone, email, chat, and ticketing systems; log, prioritize, and track customer issues to resolution while meeting SLA targets.
Perform complex troubleshooting across hardware, firmware, operating systems (Windows, macOS, Linux), mobile platforms (iOS/Android), and peripheral devices; document root causes and remediation steps.
Diagnose and resolve network-related problems including wired/wireless connectivity, VPNs, TCP/IP, DNS, and firewall-related issues both remotely and on-site when required.
Install, configure, and validate new equipment, appliances, and software for customers, following installation checklists and maintaining configuration records.
Conduct remote diagnostics using SSH, RDP, remote desktop tools, or vendor-specific utilities to collect logs, reproduce issues, and apply fixes or workarounds.
Troubleshoot and support SaaS applications and cloud integrations (API troubleshooting, token/oauth issues, multi-tenant configuration) and escalate platform defects to engineering.
Manage and update customer-facing knowledge base articles, FAQs, and troubleshooting guides to reduce repeat incidents and enable self-service.
Execute software upgrades, patches, and firmware updates following change management policies; verify system stability and rollback if necessary.
Coordinate cross-functional escalations with engineering, product, QA, and field teams, providing detailed incident reports, timelines, and reproducible steps.
Maintain accurate records of customer interactions, resolutions, workarounds, and product configurations in CRM/ticketing tools (e.g., Salesforce, Zendesk, ServiceNow).
Provide onsite technical support and service visits for complex hardware repairs, installations, or warranty work; perform preventive maintenance and end-to-end system checks.
Drive root cause analysis (RCA) for recurring incidents, recommend product improvements, and participate in incident postmortems to improve mean time to repair (MTTR).
Deliver onboarding and technical training to customers and internal teams, including walkthroughs, best practices, and configuration optimization.
Monitor system alerts, logs, and telemetry to proactively identify issues and engage customers or internal stakeholders before they escalate.
Enforce and adhere to service level agreements (SLAs), escalation matrices, and compliance/security policies while communicating impact and timelines to stakeholders.
Build strong relationships with customers by managing expectations, providing status updates, and ensuring a high level of customer satisfaction (CSAT/NPS).
Create and maintain test cases and reproduce environments to validate bug fixes and feature behavior in development/test/staging environments.
Assist product and sales teams with technical demonstrations, proof-of-concepts (POCs), and feasibility assessments for custom integrations and deployments.
Participate in on-call rotation (where applicable), responding to critical incidents and major outages with clearly documented remediation steps and communication to affected parties.
Track product defects through resolution, validate fixes in QA environments, and close related support tickets with a full explanation and future prevention strategies.
Identify opportunities to streamline support workflows and automate repetitive tasks using scripts (Bash, PowerShell, Python) or platform automation tools.
Ensure data integrity and privacy when handling customer data; follow company policies regarding secure access, data redaction, and regulatory requirements (GDPR, HIPAA where applicable).
