Key Responsibilities:

A. Team Leadership & 24x7 Operational Governance

- Lead, mentor, and direct a team of 4 to 5 SRE / Application Support Engineers operating in a 24x7 shift model.
- Plan and govern shift rosters, coverage handovers, on-call escalation rotations, and shift performance metrics.
- Establish standard operating procedures (SOPs), runbooks, and automation scripts to equip the team to handle production incidents autonomously.
- Monitor operational SLAs, Mean Time to Detect (MTTD), and Mean Time to Resolve (MTTR). B. Incident B. B. Command & Technical Escalation Authority
- Act as the Incident Commander for high-severity outages (P1/P2) impacting BOU TSP, IBMB, and core banking switches.
- Lead cross-functional war rooms with Core Engineering, Product Owners, Infrastructure teams, and external partner banks.
- Provide clear, concise executive incident summaries and technical updates during and immediately after service disruptions.
- Own end-to-end Root Cause Analysis (RCA) reports,



ensuring preventive and corrective actions are tracked to closure with software engineering teams.

C. Advanced Technical Diagnostics & Systems Optimization

- Guide the team through complex L3 debugging across distributed microservices, Java application stacks, and messaging queues (Kafka / RabbitMQ).
- Lead deep-dive log analysis, performance profiling, thread dump analysis, and database query optimization (Oracle, PostgreSQL).
- Oversee API stability, reviewing recurring integration failures across REST, SOAP, and ISO 8583 payment messaging protocols.
- Partner with engineering application owners to evaluate production readiness for new software releases, architectural changes, and gateway migrations.

D. Observability, Automation & DevOps Maturity

- Architect and refine centralized telemetry and logging platforms using ELK Stack (Elasticsearch, Logstash, Kibana) and Grafana/Prometheus.
- Drive automated alerting strategies to minimize false positives, detect systemic anomalies early, and enforce alert threshold discipline.
- Champion operational automation using Bash, Python, and CI/CD tools (Jenkins, GitLab CI) to eliminate repetitive manual operational tasks.
- Supervise containerized application health and orchestration across Docker and Kubernetes clusters.

Desired Candidate Profile:

- Experience:



7 to 10 years of experience in Application Support, Site Reliability Engineering, or Production Operations, including at least 2–3 years in a direct team lead or technical leadership capacity.
- Education: B.E. / B.Tech / MCA / M.Sc in Computer Science, Information Technology, or allied technical disciplines.
- Technical Leadership: Proven track record of leading 24x7 technical support or reliability teams in FinTech, BFSI, Payment Gateways, or high-throughput transaction systems.
- Incident Management: Seasoned experience acting as Incident Commander, running war rooms, and authoring client/partner-facing RCAs.
- Technical Depth: o Advanced Linux/Unix systems troubleshooting and shell scripting. o Deep database knowledge (complex SQL, query execution plans, deadlock resolution in Oracle/PostgreSQL). o Strong understanding of Java application debugging (JVM memory management, heap/thread dumps, connection pool mechanics). o Working knowledge of message brokers (Kafka/RabbitMQ) and container platforms (Docker, Kubernetes).
- Payment Ecosystem Familiarity: Strong functional and technical grasp of payment flows, specifically Bharat Connect (BBPS/BOU), Internet Banking switches (IBMB), UPI, or card payment gateways.
- Stakeholder Management: Exceptional communication skills with the ability to bridge discussions between product management, engineering owners, and partner bank technical teams.
- Shift Model: Roster governance across a 24x7 setting with availability to lead critical bridges during off-hours and escalations.
