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
• Efficient integration: We are not alone in a huge stack like this - this can be enhanced by better mapping, faster retrieval of recently changed data or adding a field, so we can boost our searches more efficiently
• Data modelling: Understanding its implications and effects on indexing and querying
• Performance enhancement: You are always on the lookout, keeping our search speed as fast as possible
• Safety first: With everything you touch and design, you keep resiliency in mind as a key theme in a microservice environment. You know what circuit breakers and bulk heads are and only use caches when they make sense. You favour exponential backoff over CrashLoopBackoff - a lot!
• Our team tech stack consists of Kubernetes, gRPC, Typescript, the latest Node.js major version, Elasticsearch, a bit of MongoDB, Kafka and last but not least, we are using DataDog for monitoring
