Search developer

Join our team to create and refine search engine for the largest catalogue in Europe. We are working on a new generation search which is based on machine learning and ElasticSearch. Our team allows users to find and select products from the catalogue and provides APIs for product search and filtering to other teams as well. We make it possible to search for categories, guides and even tens of millions of product offers from thousands of e-shops.

Currently, we are working on the understanding of queries that are searched by users with the help of machine learning. Also, we are building a new suggester and data aggregation for all the countries in Heureka Group. 

Queries entered by the user are analysed and the product results are sorted by the relevance. We improve our product based on user behavior, which we measure mainly using defined web metrics.

You can find the article about the technical side of search here (unfortunately, it is in czech language only): https://www.heurekadevs.cz/pod-poklickou-heureka-search

We have full responsibility for all the services we provide, but we also have great freedom in what we create. Our team has the space to bring its own innovation and challenge the existing way of things.

You can help us with:

• Data aggregation in ElasticSearch
• Improving and speeding up our Search API
• Keeping all services running - DevOps
• Developing our Machine Learning project “Query Understanding”
• Thinking critically and designing a new service architecture
• Sharing and expanding know-how in the team and the entire company
• Maintaining a good, non-conflicting mood in the team

We do not care much about the knowledge of specific technologies (unless you don't want to learn anything new), more important is logical thinking, knowledge of general principles and any back-end programming language. We also want the team to be functional on the personal level (even though we primarily "meet" via video calls), so we can have a chat and some fun first :) 

Also, you’ll come across:

• Sync/Async Python 3.x
• ElasticSearch, MySQL, Redis, RabbitMQ
• Spark, DataBricks v Azure
• Docker, Terraform, Kubernetes 

What you’ll get:

• Opportunity to participate in the development of a product that is currently used by three million unique users per month in two countries. There will be unique technical challenges that you just can't get anywhere else. Opportunity to be part of One Platform vision. 
• Great company culture and open mindset.
• Opportunity to learn a lot from the huge shared know-how we have in Heureka.
• Support you in improving your skills, including participation in training and conferences.
• Organized hackathons.
• We are working in tribes and teams which consist of developers, product manager and scrum master.
• Free working hours, working from home, and a lot of other benefits such as cafeteria, meal vouchers, etc.…
