Data Engineer



Imagine a workplace which encourages you to take on responsibility and where your ideas will be heard and implemented. Imagine a fast paced environment where your performance makes the difference. This is TrustYou! We are looking for adventurers to join our smart and inspiring team!

TrustYou creates summaries of hotel reviews, with the goal of being as useful, or more, than a summary written by humans. And it's our data engineers that make this happen!

As a data engineer at TrustYou, you will be part of an international, talented and motivated team that uses their combined knowledge of machine learning, natural language processing and big data technologies to build the TrustYou Meta-Review. You are the perfect candidate if you enjoy researching, prototyping and finetuning algorithms to solve novel problems. Our engineers are willing to walk the extra mile to make sure our solution is not only good, but great and beneficial for millions of travelers. You will systematically look for weaknesses and areas for improvement in our approaches, and will be motivated by them to create even better solutions.

TrustYou runs on Python. We employ both linguists and machine learning experts, who collaborate to build the best product possible. Our solutions need to scale to process all hotel reviews on the Internet. New projects are written in Apache Spark, while we also maintain a codebase of MapReduce jobs.

What challenges await you?

  • Being a member of the Metareview, you will be working in a cross-discipline delivery team focused on one of many core data products.
  • Gather and process raw data at scale using frameworks such as Hadoop MR and Spark.
  • Maintain and write new data processing pipelines handling hundreds of GB of data.
  • Optimize and improve existing features or data processes for performance and stability
  • Apply machine learning algorithms to improve our product and drive decisions

What do we expect from you?

  • 3+ years of experience building data intensive applications.
  • Very strong programming and architectural experience, ideally in Python, Java or Scala but we are open to other experience if you would like to become a Python hacker.
  • You find creative solutions to tough problems. You are not only a great developer, you are also an architect who is not afraid to pave the way for bigger and better things.
  • Experience and skills to clean and scrub noisy datasets.

Nice to have:

  • Expert-level knowledge in Python. Experience in frameworks such as Pandas, Scikit-learn, Scipy, Luigi / Airflow is a plus.
  • Love for the command line with optional affinity for Linux scripting
  • Experience with Big data technologies (Hadoop, Spark, Flink, Hive, Impala, HBase, Pig, Redshift, Kafka)
  • Experience building scalable REST-APIs using Python or similar technologies.
  • Experience with data mining, machine learning, natural language processing or information retrieval is a plus.
  • Experience with AWS or other IaaS/PaaS.
  • Experience with Agile Methodologies such as Scrum or Kanban

What do we offer:

  • A highly international & entrepreneurial environment (flat hierarchies, short decision paths…)
  • Excellent onboarding programs
  • Spend up to 5% of your working time for your professional & personal development
  • Great leadership & support

TrustYou has engineering excellence in its DNA. Our employees are experts in big data, machine learning, natural language processing, interactive JavaScript applications and web technologies. Our tech stack is varied and modern!
