Senior Security Data Engineer

  EXPERIENCE: 5–10 Years  

Core Responsibilities:  

• Pipeline Management: Maintain high-throughput streaming pipelines to ingest logs  from various sources (Firewalls, Cloud, Endpoints) to a central destination.  

• Log Normalization: Write parsers to convert raw, messy logs into standard  schemas (e.g., OCSF or ECS) for consistent querying.  • Cost Optimization: Implement routing logic to send "high-value" data to the SIEM  and "bulk" data to low-cost Object Storage (Data Lake).  

• Data Preparation: Clean and structure data to enable AI/ML detection models  and advanced analytics.  

Must-Have Skills:  

• Data Engineering: Proficiency in Python (for ETL) and SQL (for complex querying).  

• Streaming Tech: Experience with Message Queues (e.g., Kafka, Pub/Sub) and  stream processing concepts. 

 • Log Handling: Mastery of Regex and log parsing strategies for standard formats  (Syslog, CEF, JSON).  

• Storage Architecture: Understanding of Data Lake principles (Parquet/Avro formats)  vs. Data Warehouses.  

Preferred / Nice to Have: 

 • Experience with Vector Databases for storing embeddings.  

• Knowledge of Log Observability/Routing tools (middleware that routes logs).  

• Familiarity with Big Data frameworks (e.g., Spark, Flink).
