To deliver, we are designing, implementing and operating an extensive system combining modern microservice architecture with high performance backends and vast data sources. We care about data quality and availability and strive for near real-time accuracy, to best guide users to products and offers in a highly dynamic marketplace.
Flexible working hours in the hybrid model (4/1) - working hours start between 7:00 a.m. and 10:00 a.m. We also have 30 days of occasional remote work.

Massive Scale: Design, build, and optimize systems that handle thousands of requests per second. This is high-availability, high-performance engineering in practice.
Modern Tech Stack: Work with a world-class, cloud-native environment. Our core technologies include Kotlin, Spring, Kafka, and Kubernetes. On the back side, there is Vespa and a highly optimized and heavily customized Lucene/Solr installation. Were not shy when it comes to ML too :)
True Ownership & Autonomy: We live by a "you build it, you run it" philosophy. Youll join an agile, autonomous team with full ownership of your microservices, from design to deployment; and improvements are dictated by results of our own experiments.
Complex Challenges: From distributed systems and data streaming to algorithmic optimization, youll tackle the complex backend problems that power a massive, real-time marketplace. And a constantly modernizing approach to search solutions will give you the opportunity to work with advanced embedding and ranking models and pipelines.
