Job Description

About you:

You understand how computers work and what role an operating system plays. You know why the Linux kernel is written in C and not any other language. You have a favorite file system, you know what a syscall is and you are comfortable exploring /proc and /sys. You like using Go every day, are not afraid of Makefiles and you enjoy when thousands of servers bend to your will.

You should also be comfortable joining an early stage company with a dynamic future. We offer a great salary, but expect you to value the equity as well. In return we will be very transparent with you about the company finances and outlook. You are joining a founding team and we want you to enjoy the ride.

If you are this kind of person, here is what you will be working on:

• Building solutions using Go, systemd and runc and Kubernetes.
• Designing and building new open source products that you can be proud of like Teleport.
• Talking to customers and converting complex requirements into simple and elegant solutions.

About Gravitational:

Gravitational, an early stage systems & cloud startup, is looking for ambitious and talented people. We are well-funded by fantastic Silicon Valley investors. We are an experienced team: we founded Mailgun which was acquired by Rackspace, we created Vulcand and some other cool stuff at Rackspace and are authors of Teleport and Telekube.

We are hackers. We love Linux and low level systems programming and we love helping open source communities and other engineers to get things done.

We are also dedicated to our friends, families, and hobbies outside of work. Our past experiences building companies taught us about the importance of life and work balance. It matters even more when you are building a lasting company, like Gravitational.

About the tech:

You'll be using Go as your primary weapon, but we expect you to be comfortable reading and navigating C code bases.

You don’t have to be an expert in these things, but you should be ready and excited to become one:

• Kubernetes and containers
• Ansible
• AWS management, Terraform
• Linux administration, Linux networking

Job Description

And we are using technology to explore new approaches to consumer credit marketplaces that have never been attempted before.

• Experience building scalable, reliable distributed systems
• Experience developing systems intended for cloud deployments (we use AWS)

It’s your aspiration to ensure an error free operation of all our production systems through a mixture of code reviews, unit + integration tests and monitoring.

High requirements merit appropriate compensation. We are competing with other companies for your time and knowledge. So why should you decide to join us? Naturally this is quite hard to answer and depends on a lot of factors. Therefore we would be happy to answer all your questions regarding Barzahlen 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.

Qualifications:

• 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
