Frontend Engineer

Hasty GmbH

Full TimeReact50-70BerlinGermany
Posted 26d ago

We at Hasty are looking for a great Frontend React Engineer to join our growing team of 10. We are looking for someone who wants to join an early-stage venture-backed startup with already existing traction and financing, and be part of our experienced frontend team.

About us:

We are a Berlin-based startup that specializes in machine learning and computer vision. During the last 18 months, we built the top annotation tool on the market for machine learning and we are evolving that to cover more of the total user journeys to become a more comprehensive tool. If you’re not familiar with the concept of annotation, think about it like Photoshop - but instead of creating visuals, you are marking what is in an image to train an AI. Those markings or annotations, as they are called in the industry, are then used to give context for images to train machine learning algorithms. This is the bread and butter of modern vision AI development, and we are making this process up to 10x faster when compared to other tools, meaning that our users can build and train higher quality AI models much faster than ever before.

We get that 10x gain in efficiency for users by offering a novel approach, where humans and machines can collaborate together in our UI. Our AI models create suggestions which users can then accept, reject, or edit. That feedback is then used to improve our models, which will create better suggestions leading to a virtuous cycle of increased efficiency and increased transparency into AI models.

About the role:

As a full-time frontend engineer, you will be working on building complex interfaces. It’s a real challenge, with plenty of difficult technical problems to solve. Expect to work on canvas manipulation, WebSockets integration, and integrating machine learning into a product that everyone can use on an everyday basis. 

There’s a lot of variance in the work we do too, so if you are a person that enjoys new challenges and grows bored with repetitive work, we have the workplace for you. 


A Frontend Engineer with at least 2 years of experience with React and, ideally, 4 years of experience with JavaScript. Someone who writes JS-code using best practices and has expert knowledge of CSS. Preferably, they like to work on complex problems and are proficient in optimizing web performance. 

We love people who take ownership of their work and are not happy with a feature until it makes the product a better experience for all users. We need someone who cooperates well with others and takes the time needed to do proper code reviews and gives constructive feedback to the rest of the team. 

What we offer:

We offer a competitive salary package, the possibility to have flexible working hours and a lot of autonomy of how you do your work and how you structure your day. You will be given responsibility and have ownership of your tasks. We are, of course, there to support you as you need.

Last but not least, we think the major perk in working here is to work with a senior team of people who are both uniquely brilliant and great at supporting each other.
