This is not an internal IT role.
This is not a helpdesk position.
This is a vendor-grade technical leadership role operating at OEM engineering standards, supporting mission-critical server and storage environments across multiple regions.
ABOUT THE ROLE
Maintech is looking for a hands-on Level 3 Subject Matter Expert who can take full ownership of complex technical escalations, perform deep troubleshooting and root cause analysis, and provide final technical direction for critical customer issues.
You will act as the senior technical escalation point for incidents that cannot be resolved by L1 and L2 teams.
This role requires:
Strong analytical and troubleshooting capability
Technical ownership from investigation through resolution
Strong customer and cross-functional communication
The ability to operate effectively in mission-critical environments
This is not a ticket coordination or pure people management role. The successful candidate must remain technically hands-on.
WHAT YOU WILL OWN
Take ownership of complex incidents escalated by L1 and L2 support teams
Serve as the senior technical escalation point for high-impact, recurring and business-critical issues
Assess technical impact, urgency, risk and resolution priorities
Provide final technical direction and drive incidents through to closure
Work with engineering teams, vendors, product teams and regional SMEs when required
Deep Troubleshooting and Root Cause Analysis
Analyze system behavior, logs, error messages, configurations and performance data
Identify the actual root cause instead of providing only temporary workarounds
Validate findings through evidence, testing and technical analysis
Develop corrective and preventive actions to reduce recurring incidents
Clearly distinguish between service restoration and permanent resolution
Major Incident and Critical Issue Management
Participate in major incident calls and technical war rooms
Provide technical direction and recommendations during critical incidents
Support rapid decision-making under time-sensitive and high-pressure conditions
Communicate incident progress, technical risks and recovery plans to customers and internal stakeholders
Complete RCA reports, incident reviews and follow-up improvement actions
Technical Solutions and Risk Assessment
Recommend remediation, upgrade, migration or infrastructure improvement solutions
Assess technical risks and potential business impact before changes are implemented
Support complex deployments, migrations, upgrades and system integration activities
Ensure proposed solutions comply with customer SLAs, security policies and operational procedures
Provide technical recommendations that improve system stability, performance and reliability
Knowledge Transfer and Team Development
Guide L1 and L2 engineers through complex technical issues
Mentor engineers and improve the team's overall troubleshooting capability
Develop troubleshooting guides, SOPs, technical runbooks and knowledge base documentation
Conduct internal or customer-facing technical training
Improve escalation procedures and standardize troubleshooting practices
WHAT WE ARE LOOKING FOR
Strong hands-on experience in enterprise systems, infrastructure or a relevant technical domain
Proven experience handling L3 escalations, complex troubleshooting or mission-critical incidents
Ability to independently perform log analysis, root cause analysis, solution design and risk assessment
Experience with incident, problem and change management processes
Strong ownership and the ability to drive issues through to closure
Experience supporting enterprise customers or large-scale environments
Ability to clearly explain complex technical issues to customers and non-technical stakeholders
Professional English communication skills for technical meetings, written reports and cross-border collaboration
Willingness to remain technically hands-on rather than operating only as a people manager or coordinator
PREFERRED QUALIFICATIONS
Previous experience as a Technical Lead, Lead Engineer, Escalation Engineer or Subject Matter Expert
Experience supporting regional or global teams across multiple time zones
Experience in financial services, government, telecommunications, manufacturing, data centers or other highly regulated environments
Familiarity with ITIL, incident management, problem management and change management
Relevant certifications in infrastructure, cloud, server, network, storage or cybersecurity
Experience with automation, scripting, monitoring or reporting tools
Experience creating SOPs, technical runbooks, knowledge bases or training materials
Experience participating in migration, deployment, upgrade or infrastructure improvement projects
Experience working directly with OEM engineering teams, product teams or global SMEs
Your experience is mainly limited to monitoring, ticket assignment or incident coordination
Complex issues are normally transferred to vendors without your continued technical ownership
You have moved entirely into people management and no longer perform hands-on troubleshooting
Your experience is limited to standard procedures and known issue playbooks
You have not personally conducted root cause analysis or developed permanent corrective actions
You prefer to escalation issues rather than remain accountable until final resolution
