Aufgaben
Your tasks – this is what awaits you in detail
- As a Staff Search Engineer (all genders) your goal is to bring our search to the next level for our customers
- Improving our relevance: Writing faster queries, improving data quality of ingested data and by making decisions on better vs. worse relevancy - you understand our searches inside out to make and share informed decisions
- Enriching our ingestion architecture: Consuming change events, updating Elasticsearch mappings and indexing into new fields, ensuring we are able to index into a single document from multiple sources
