Our friends at Harbour.Space also have a message for you:

Attention tech specialists!

Harbour.Space Barcelona is proud to announce a collaboration with one of our industrial partners to offer a fully funded scholarship for our one year Master’s in Data Science Programme at HSU Barcelona.

The Scholarship includes:

  • Full coverage of the Programme’s tuition fee (€23,000 value)
  • 3 hours of study a day at Harbour.Space University
  • 4 hours of internship a day with one of our industrial partners
  • €12,000 euros a year (living allowance)

Our data science programme will feature super star teachers like Mike Mirzayanov (Advanced Algorithms and Data Structures), Alexey Dral (Big Data: Map Reduce, Spark, BigTable/HBase) and Alex Dainiak (Discrete Optimisation), plus many more.

Harbour.Space is unique because:

  1. We don’t play by the rules. We bring practicing professionals, not only academic teachers, who come teach for intense, 3 week modules. HSU students are encouraged to experiment, fail, and try again, until they succeed.

  2. We are your home. Harbour.Space is a community of over 40 nationalities, and we're still growing.

  3. We provide an experience. Harbour.Space University is located in Barcelona, one of the most vibrant cities of our time.
