What is a Tier 3 Support?

A Tier 3 Support job involves providing advanced technical support for complex issues that cannot be resolved by Tier 1 or Tier 2 teams. Tier 3 specialists diagnose deep-rooted software, hardware, or network problems, often working closely with developers or engineers to identify and implement solutions. They may also assist with bug fixes, system optimizations, and documentation for recurring issues. Their role requires extensive technical expertise, troubleshooting skills, and a deep understanding of the product or system.

What types of issues does a Tier 3 Support specialist typically handle compared to Tier 1 or Tier 2 support roles?

Tier 3 Support specialists are responsible for addressing the most complex and challenging technical problems that cannot be resolved by Tier 1 or Tier 2 teams. These issues often involve in-depth troubleshooting, root cause analysis, and collaboration with developers or product engineers to resolve systemic or advanced hardware/software problems. Unlike earlier tiers that handle basic troubleshooting or account support, Tier 3 handles escalations that may require specialized knowledge or the creation of permanent solutions. This role is highly collaborative, often involving cross-team communication and direct involvement in critical incident management. As a result, professionals in Tier 3 Support gain valuable expertise and exposure that can lead to specialized engineering or leadership career paths.

What are the key skills and qualifications needed to thrive in the Tier 3 Support position, and why are they important?

To thrive as a Tier 3 Support professional, you need deep technical expertise in troubleshooting complex systems, advanced problem-solving abilities, and experience with relevant industry technologies. Familiarity with ticketing systems, network and server diagnostic tools, and certifications such as CompTIA, Microsoft, or Cisco are often expected. Strong analytical thinking, effective communication skills, and the ability to mentor others help distinguish top performers. These skills are crucial for efficiently resolving escalated issues, supporting internal teams, and maintaining high service standards for customers.

Job description

NIRA, Inc. is seeking a Tier 3 Support Engineer to serve as the final escalation point for a U.S. Department of Justice cloud-based digital evidence management program serving U.S. Attorneys' Offices nationwide. Sitting behind district-level Tier 1 and nationwide Tier 2 help desk support, this engineer resolves the most complex platform, integration, and data issues - working across a FedRAMP High SaaS evidence platform, enterprise integrations, and AWS GovCloud infrastructure under SLA-driven incident and service request management.

Responsibilities

  • Own Tier 3 resolution of incidents and service requests escalated from Tier 1 and Tier 2 support, working tickets against priority-based MTTR/MTTC service levels
  • Troubleshoot across the full stack: application behavior, identity/SSO and access issues, system integrations (ITSM, eDiscovery review, SIEM), data ingestion and export failures, and cloud infrastructure
  • Perform root cause analysis on complex and recurring issues; promote repeat incidents into change requests and bug-fix candidates for maintenance releases
  • Manage product-level escalations to OEM engineering teams while retaining ownership of ticket status and customer communication
  • Work within the enterprise ITSM ticketing environment, maintaining accurate ticket documentation, work-time tracking, and escalation records
  • Support security operations: patch verification, vulnerability remediation validation, and incident response assistance
  • Maintain runbooks, knowledge base articles, and known-issue documentation; feed resolution knowledge back to Tier 1/Tier 2 teams
  • Contribute to monthly service desk reporting and SLA performance reviews; participate in an on-call rotation for after-hours critical incidents

Required Qualifications

  • 5+ years of technical support, application support, or systems engineering experience, including at least 2 years at a Tier 3 or escalation-engineering level
  • Strong troubleshooting skills for cloud-hosted SaaS and web applications, including log analysis, SQL queries, and API-level diagnostics
  • Working knowledge of AWS services and monitoring/diagnostic tooling
  • Experience troubleshooting authentication and access issues (SSO, SAML/OIDC, role-based access)
  • Experience in ITIL-based incident and problem management using enterprise ticketing systems (SCSM, ServiceNow, or comparable) in SLA-driven environments
  • Clear written and verbal communication with both end users and engineering teams, including RCA documentation
  • U.S. citizenship required; must be able to obtain and maintain a DOJ High-Risk Public Trust (Tier 4) background investigation
  • Bachelor's degree in information technology, computer science, or a related field

Preferred Qualifications

  • Federal support experience, ideally DOJ or law enforcement; familiarity with FedRAMP High environments
  • Experience supporting digital evidence, forensics, or eDiscovery platforms (e.g., Cellebrite, Relativity, Everlaw)
  • Scripting skills (Python or PowerShell) for diagnostics and support automation
  • Experience supporting multi-tenant SaaS environments
  • Certifications such as ITIL 4, AWS SysOps Administrator, or Security+
