Descripción de la oferta

Wallapop is a Barcelona based scale-up driven by the purpose to empower people to embrace a more conscious and human way of consumption. We believe in a world where collaborative economy is mainstream. This is what drives us.

Wallapop operates in Spain, Italy and Portugal, offering a catalogue of several hundreds of millions of products and services. Powered by technical innovation and continuous improvement, we bring together the scale & trust of classifieds with the marketplace’s convenience & reach. Our mission is to enable a connected trade ecosystem, making 2nd-hand the norm through smart use of technology.

Backed by top investors such as Accel, Insight Partners & Naver Corp we bring our total valuation to 690 million EUR and are embarking on our international journey with the aim to become the world’s best unique goods trading platform.

 

The Challenge

Our search engine serves several millions of searches per day to satisfy the information needs of more than 15 million unique users. Our searchable catalog counts in several tens of million documents with thousands of new products entering and selling products leaving the system in real time. This poses interesting challenges in terms of relevance, resiliency, scalability and performance to give our users fast and meaningful search results. We use many different open-source and AWS technologies to achieve our goals. As a Wallapop search engineer, we have ownership of the team microservices, so we really embrace DevOps philosophy. Some key technologies in our stack are:

 

  • Lucene and Solr (M/S and cloud modes)
  • Java & Kotlin
  • Spring Framework
  • RabbitMQ
  • MySql, DynamoDb, Redis & Memcached
  • Docker
  • AWS: S3, ECS, CloudWatch, RDS, CloudFormation, Lambdas & more
  • Elastic search and Kibana

We are really friendly and expect any new members to join us to be respectful, appreciate diversity, and have a sense of humor. We are constantly learning new technologies, acquiring new skills, as things change fast at Wallapop. And Wallapop is aware of that fact, so every employee has a budget for courses and conferences.

 

What You Will Do

  • Writing Java code for our Search Backend
  • Develop, extend, optimize and maintain our search, recommendations and suggestions engines (solr-based)

  • Relevance tuning
  • Assist in the development of our LTR models
  • Participate in team meetings to design new features
  • Co-operate with mobile engineers, data analysts, product designers to develop Wallapop's unique search experience
  • Testing all the things! Testing is a must, especially if you want to avoid those friendly reminders during the code review

 

What We’re Looking For

  • Problem solver and critical thinking
  • Knowledgeable of Information Retrieval models, ranking formulas and concepts
  • Knowledgeable of standard solr components and functionalities (suggesters, spell-checkers, default components, faceting, etc)
  • Experienced in architecting, monitoring and optimizing NRT search systems for high volume and high traffic
  • Experienced in tuning relevance and developing new ranking/sorting algorithms
  • Experienced in multi-lingual search systems
  • Quality driven, attention to detail and pragmatic ̣
