IT Application Consultant T2 (Germany)

Description:

Key Responsibilities

• Design and implement high-throughput collectors and protocol decoders for NetFlow v5/v9, sFlow, and IPFIX telemetry data ingested from multi-site enterprise network infrastructure.
• Build and maintain flow enrichment pipelines that correlate raw flow records with CMDB, IP-to-AS mapping (BGP), GeoIP, VLAN, and application classification data.
• Develop real-time analytics and aggregation engines capable of processing millions of flow records per second with sub-second query latency.
• Create scalable REST and GraphQL APIs to expose traffic insights, trend data, and alerting thresholds to downstream consumers and dashboards.
• Integrate with time-series and columnar data stores (ClickHouse, InfluxDB, Apache Druid) for long-term flow retention, roll-ups, and historical analysis.
• Implement anomaly-detection and traffic-baselining algorithms to identify deviations in application, site, or user traffic patterns.
• Collaborate with network engineers to validate flow accuracy, debug protocol discrepancies across vendors (Cisco, Juniper, Arista, Palo Alto), and certify new device onboarding.
• Contribute to the design of multi-tenant architecture, ensuring data isolation and role-based access for enterprise customers with hundreds of network sites.
• Champion engineering best practices through code reviews, technical documentation, and participation in architectural decision records (ADRs).
