Job Description

 

 

 

Category-defining tech. Career-defining work.

Lots of tech companies disrupt. But, many fail when they try to scale. We're different. CockroachDB makes it easier for companies to build and scale apps. This is how and why we're helping some of the most innovative companies on the planet. We tackle problems head-on and focus on solutions that create lasting impact. 

Because when our customers win, we all win. 

 


The Role

We are looking for a backend software engineer excited about growing an open-source, cloud-native distributed SQL database to join our SQL Queries team.

  • Take part in a collaborative culture and exchange knowledge with a highly experienced technical organization.

We believe that it's essential for you to take this time to become familiar with our technology, company, and our culture.

After three months, you'll be a fully-fledged member of the SQL Queries team and feel comfortable contributing to CockroachDB. You will begin determining the parts of our product that most interest you and work with your manager to focus your efforts on projects that align with your interests and our goals.

We want our users to have a phenomenal experience using our product. You play a crucial role in making CockroachDB a joy to use, and as our team grows, you will have the opportunity to shape the direction of development for CockroachDB and CockroachDB Cloud. We also offer technical training and experienced mentorship to help you learn and advance your career into whatever you wish it to be.

You Have
