🎯 Role Definition

A Technical Customer Service Representative (TCSR) is a front-line specialist who combines deep product and technical knowledge with outstanding customer-facing skills to diagnose, troubleshoot, and resolve customer issues across channels (phone, email, chat, and ticketing systems). The TCSR manages incidents to SLA, documents solutions in knowledge bases, escalates complex issues to engineering or product teams, and continuously drives improvements in customer satisfaction (CSAT), first contact resolution (FCR), and mean time to resolution (MTTR). This role frequently supports SaaS platforms, hardware products, cloud services, networking, and integrations (APIs), and serves as the voice of the customer to internal stakeholders.

  • Diagnose network connectivity, DNS, VPN, firewall, and basic TCP/IP issues; provide clear, step-by-step guidance to customers to isolate network-related root causes and validate fixes.
  • Support SaaS and cloud-based products (AWS, Azure, GCP) including account provisioning, permissions, integrations, and common API/REST issues; guide customers through integration troubleshooting and authentication flows.
  • Manage the full incident lifecycle: acknowledge, investigate, escalate, communicate status updates to customers, and close tickets with appropriate resolution notes and follow-up actions.
  • Execute remote support sessions using remote-desktop tools, secure shell (SSH), and diagnostic utilities to collect logs, run commands, and apply fixes while following security and privacy procedures.
  • Analyze error messages, stack traces, and system logs; correlate customer reports with telemetry and monitoring data to identify recurring issues and potential product defects.
  • Use CRM and ticketing platforms (e.g., Zendesk, Salesforce Service Cloud, Freshdesk, Jira Service Desk) to log interactions, update statuses, tag relevant products/components, and track SLAs and escalations.
  • Perform root cause analysis on escalated cases, coordinate cross-functional triage with engineering, QA, product, and operations teams, and drive to a timely customer-facing resolution.
  • Maintain and contribute to the internal and public knowledge base by writing clear, searchable troubleshooting guides, how-to articles, and FAQ updates to increase first contact resolution and reduce repeat inquiries.
  • Provide input on product usability, documentation gaps, and recurring customer friction by synthesizing customer feedback and trend data for product managers and engineering teams.
  • Assist customers with account management tasks related to billing, subscription plans, licensing, and user provisioning in coordination with billing and customer success teams when required.
  • Participate in on-call rotation for after-hours incident response, perform urgent triage of critical outages, and follow incident management runbooks to restore service and communicate post-incident updates.
  • Monitor dashboard alerts and escalations for high-priority incidents, proactively reach out to impacted customers, and provide timely workarounds or mitigation steps while coordinating incident resolution.
  • Educate customers on best practices for product configuration, security hardening, backup strategies, and performance optimization to reduce support incidence and improve adoption.
  • Uphold data privacy, security, and compliance requirements when accessing customer environments; log access, obtain necessary approvals, and follow secure troubleshooting protocols.
  • Track case metrics (CSAT, NPS proxies, ticket backlog, MTTR, FCR) and work with the support manager to implement process improvements to drive measurable gains in operational performance.
  • Deliver remote or in-person training sessions, webinars, and product demos for customers and internal teams to improve product understanding and reduce repetitive support requests.
  • Facilitate customer escalations to Tier 2 / Tier 3 engineering by providing comprehensive case summaries, reproduction steps, affected environments, and priority recommendations to expedite resolution.
  • Participate in beta programs and early access testing; gather structured feedback and report issues found by customers or discovered during onboarding and migrations.
  • Maintain up-to-date knowledge on product releases, patch notes, feature updates, and change management that impact customers; proactively communicate known issues and planned mitigations.
  • Collaborate with sales, implementation, and account teams to support complex onboarding projects, migrations, and feature enablement that have technical dependencies.
  • Document non-standard workarounds and temporary fixes for critical issues and ensure they are reviewed and adopted into formal KB articles or runbooks when validated.

Secondary Functions

  • Lead or participate in cross-functional projects to improve support tooling, automate repetitive tasks (macros, triggers, scripts), and scale support operations.
  • Build and maintain internal dashboards and reports to highlight ticket trends, product areas with high defect density, and opportunities for automation and knowledge base expansion.
  • Mentor junior support staff, conduct regular QA reviews of tickets and calls, and deliver coaching to improve technical troubleshooting, ticket quality, and customer communication.
  • Contribute to the organization’s customer success and retention strategy by identifying churn signals, upsell opportunities, and areas where customers need additional enablement.
  • Participate in product roadmap discussions to prioritize customer-impacting defects and feature enhancements based on aggregated case data and customer severity.
  • Support quality assurance cycles by validating bug fixes, documenting test cases related to customer-reported issues, and verifying that production fixes resolve the original customer problem.
