Software Engineer (f/m/*)

We operate Germany's largest independent payment infrastructure. Customers can use different services in several supermarkets to e.g. pay their invoices and deposit or withdraw cash from their private bank accounts using smartphone apps.

In the process of further developing our systems and implementing new projects, we are looking for software engineers that meet the following criteria:

• You love coding! Software development is not just a job for you. You code on private projects as well and you are interested in the industry’s latest developments. You are fluent in at least one programming language.
• In the future, you want to program in Ruby and Go! It would be awesome, if you have already worked with these two languages but in case you have not, that is also no big deal. In our experience, developers get productive in these languages very fast.
• You are interested in the big picture! You want to know and understand how everything is connected, starting with our public APIs, to our internal services and the PostgreSQL database. It is your goal to ensure an error free operation for all our production systems through a mixture of code reviews, unit + integration tests and monitoring.

We know you are in high demand. Here is why we are different and why you will love working for us:

• Our office is located in the middle of Berlin and is easily accessible using public transportation. We will procure your preferred technical devices, so that you can code as productively as possible.

We will be happy to tell you more about this in a personal chat.

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.

• Extensive experience writing applications with Python
• Experience with Golang is a plus
• Experience designing and operating distributed systems

• 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
