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.

• 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

• 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

Job Description

We're looking for someone who has: - At least 5 years of software engineering experience. - Significant experience writing Golang. - Built an open source framework for software development. - Significant open source software contributions. - Experience working in an agile development environment. - The ability to take ownership and see initiatives through. - Worked with and mentored junior engineers. - Exceptional communication skills. - Experience working with distributed teams.

What your primary responsibilities will be: - Improve the SDK codebase by committing DRY, well tested code. - Work with the SDK team to triage tickets and move the project forward. - Review pull requests and provide valuable feedback to members of the team and open source contributors. - Mentor junior engineers and support the growth and health of the team. - Help with developer adoption by supporting projects using the SDK. - Participate in developer discussion forums and work to improve the usability based on user feedback. - Promote the SDK by publishing blog posts and guides.

What we offer: - The opportunity to build the future of the internet. - An exciting role building open source software. - Flexible work schedule. - At least 4 weeks of paid vacation. - Very competitive salary, including equity.

About our application process:

Qualified candidates can expect to go through a 4 step interview process. The first interview will be a call to assess cultural fit and to make sure our goals are aligned.

If we think there is a good fit, you'll have a call with one of our project managers to learn more about your skills and attitudes toward teamwork. If it's clear that you'd be a good addition to the team, we’ll ask you to complete a technical task for which you will be compensated.

If your technical task displays a high level of quality and care we will set up a final interview with our CEO or CTO.

The process can take up to 3 weeks.
