Senior Technical Authority Expert

Join our Team

About this opportunity
Ericsson is seeking an experienced Technical Authority (Engineer) to join our world-class operations team. You will deliver 24x7 L2 production support for the HP‑IUM mediation platform, ensuring uninterrupted processing and delivery of CDR/EDR data to downstream billing and charging systems while meeting strict SLAs. The role focuses on rapid incident resolution, proactive monitoring, job recovery and maintaining operational stability in a high-availability telecom environment.

Key Responsibilities
Provide shift-based 24x7 L2 support for the HP‑IUM mediation platform to ensure continuous ingestion and processing of usage records and timely delivery to downstream systems.
Monitor mediation jobs, file ingestion, queues, JR Add/Job Runner schedules, throughput, and output delivery; detect and act on failures, delays and capacity issues.
Execute restarts, reruns, replays and recovery actions per SOPs and runbooks to restore processing quickly.
Ensure usage data meets billing/charging timelines, particularly during peak and billing-critical cycles.

Incident Management (L2)
Respond to production incidents and alerts; perform rapid impact analysis and containment.
Troubleshoot to identify root cause categories (configuration, data, job definitions, environment, infrastructure).
Collect and analyze logs, job outputs and evidence; document findings and escalate to L3 or vendor teams with comprehensive artifacts when required.
Coordinate with cross-functional teams during incidents and communicate status to stakeholders.

Monitoring & SLA Compliance
Proactively monitor job schedules, execution status, latencies, file counts and backlogs to maintain SLA compliance.
Track end-to-end latency and throughput; raise early warnings and coordinate mitigations to prevent SLA breaches.
Contribute to outage post-mortems and continuous improvement activities.

Unix/Linux Operations
Perform Unix/Linux administration tasks needed for mediation operations: log inspection, file system checks, permissions and disk utilization management.
Validate and maintain cron jobs, perform housekeeping and support basic shell scripts used in mediation workflows.
Use command-line tools for troubleshooting and data validation during incidents.

Change & Release Support
Support minor configuration changes, deployments and production updates; perform post-change validation and monitoring.
Follow change management processes, execute rollbacks when necessary, and ensure changes are documented and validated.

Documentation & Handover
Maintain accurate incident tickets, shift handovers, runbooks and SOPs; enable effective knowledge transfer across shifts.
Participate in daily operational calls, governance reviews and continuous improvement initiatives.

Required Skills & Experience
Hands-on production experience with HP‑IUM mediation or equivalent mediation platforms.
Experience with JR Add / Job Runner or similar batch scheduling/job orchestration tools.
Strong Unix/Linux operational knowledge, log analysis and basic shell scripting.
Familiarity with mediation data formats (CDRs/EDRs) and data validation techniques.
Prior experience in 24x7 NOC/operations/production support environments with strong incident handling skills.
Working knowledge of ITIL processes (Incident, Problem, Change) and ability to perform under pressure during billing-critical timelines.
