What You Will Do
Investigation & Bug Management
Independently investigate escalated, non-playbook incidents using application logs, distributed traces, database queries, and source code - investigation goes all the way down to the code level when needed
Replicate production issues end-to-end and produce a clear, structured root cause document - covering the trigger, failure mechanism, blast radius, and business impact
Craft a well-reasoned solution recommendation based on the identified root cause and failure pattern - not just a workaround or a follow-up; a proposed fix direction that delivery teams can act on
Raise and document bugs with the precision and completeness that development teams need to move immediately - reproduction steps, log evidence, code-level findings, impact scope, and recommended solution approach
Work actively with delivery teams (Dev, QA, architects) to drive the proposed solution to production; own the closure loop - not just the escalation
Incident Response
Serve as the technical SME for incidents affecting your assigned services
Engage immediately during major incidents - correlate signals across observability platforms, perform log analysis, drive parallel investigation tracks, and execute workarounds within SLA
Participate in war room calls; contribute structured, evidence-based troubleshooting
AIOps & Observability
Use AIOps Observability platforms for deep-dive investigation - correlate APM traces, infrastructure metrics, log data, and anomaly signals to isolate root cause faster and with more precision
Identify gaps in service observability - missing monitors, unmapped services, incomplete trace coverage - and raise actionable recommendations to improve investigation capability across assigned services
Understand how alerts flow from observability tools into the incident pipeline; distinguish signal from noise during active incidents
Runbook & Knowledge Management
Own runbook and KB article coverage for all assigned services - current, accurate, and executable by L1
Produce post-incident documentation (impact, RCA, mitigation, updated runbook) after every major incident
Conduct knowledge transfer sessions to the L1 Technical Service Desk for newly documented playbooks
Automation & Tools Development
Identify and build automation solutions that reduce ticket volume and cut handling time
Develop tools using Python and scripting; contribute to internal automation platforms
Service Transition
Own the L2 side of Operational Readiness for new or enhanced products - participate in training, shadowing, and reverse-shadowing with development tribes
Minimum Qualifications
Bachelor's degree in Computer Science, Information Technology, or equivalent
At least 7 years in IT application support, SRE, DevOps, software development, or a related technical operations role
At least 3 years in a senior L2, L3, or equivalent production support role in a high-traffic, distributed, cloud-native environment
Demonstrated experience working independently - owning services, making technical decisions, and interfacing directly with senior engineers, architects, and business stakeholders without supervisory oversight
Hands-on experience with Unix/Linux, relational databases (MySQL or PostgreSQL), Kubernetes, and an ITSM platform
Demonstrated ability to read and navigate application source code to the level required for root cause analysis and solution formulation - prior software development, SRE, or DevOps experience is strongly preferred
