Pluspunten
Location, Barcelona, is my favourite European city. Good perks, especially if you are employed from external grant you get some courses for professional development offered by the Barcelona Institute of Science and Technology. Top-notch computing infrastructure. Although I don't really have a boss, I truly like my "nominal" supervisor ! Attention diversity issues.
Minpunten
Most positions are fixed-term. Permanent roles are basically only for Spanish people, looking at their current staff members. Salary is not great.
