Job Description
Why Hasty?
Annotating data is an expensive hassle that nonetheless is the backbone of almost all applications of AI today. We are trying to take away some of that pain by assisting and automating to as high a degree as possible the process of labelling images, using machine learning. By doing so, we hope to open up the field of vision-based AI for new applications and for organizations that previously couldn’t use AI-powered technology as it was too expensive for them or because they lacked the technical know-how needed to develop an AI-solution from scratch.
As a workplace, we can offer you the opportunity to work on the cutting edge of AI in a startup environment, where you help us build a product from the ground up while being part of the core team with a voice in what we should do next.
Qualifications:
4 years of experience in designing and building complex software systems
Extensive experience writing applications with Python
Experience with Golang is a plus
Experience designing and operating distributed systems
Experience performing code reviews and pair-programming with other software engineers
Proactive communication and excellent teamwork skills
Ability to work independently and take ownership of tasks
What we offer:
Competitive package with equity and a sizeable learning budget that you can spend as you wish to develop yourself
A real problem to solve with the potential of having a real impact on the world around us
A startup environment with flat hierarchies
Support from a WATTx, a Berlin-based company builder, offering you the security and support of a larger organization
Workplace flexibility - Home-office, remote, adjustable working hours - we place our trust in you being the best person to plan your workweek
A great place for the intellectually curious, as we are sharing offices with other startups in the AI landscape
