RECRUITMENT PROCESS:

SALARY RANGE: 4600 - 5500 Euro net per month

ASPER BROTHERS is a dev shop/software house with an office in the very centre of Warsaw. We are characterized by a friendly approach, passion for the latest technologies and pedantic work.

We have a team of 30 great people and we’re growing steadily.

Among our clients you very rarely meet non-technical people, so we talk to them in a “common language”.

We want to cooperate with people who will have a real impact on the direction, shape and development of projects every day. We believe in self-sufficient scrum teams.

PROJECTS:

Together with our clients we change various industries through new technologies. From the inside you will see, for example:

  • How, through software, sales are scaled in a SaaS listed HR startup of several hundred people.
  • How automated real estate valuation models supported by machine learning are turning the United Arab Emirates into a real estate leader instead of an oil leader.
  • How a CRM designed for nonprofits can help rehabilitate thousands of people in the U.S.
  • How you can optimize your fitness workouts by using multiple sensors and Augmented Reality.
  • How you can simplify your entire financial life with an all-in-one tax and accounting app.
