Why Apply?

Small team, global impact

We believe small companies are beautiful, and that small teams can achieve big things. This makes everyone on the team an important part of Buildkite.

Flexible work hours

We don’t keep set office hours, so you can shift your hours around life’s commitments and non-work activities. Take time out of work for exercise, family or whatever life throws at you.

Support and growth

In a small but growing company, you’ll have the opportunity to work on a wide range of projects, and ship work that helps customers.

Work from anywhere

We’re a globally distributed company, and all our work happens remotely. Work from your home office, a co-working space, or your local cat café.


Learning & development

Invest in your personal and professional development with a yearly budget to spend on travel, conferences, workshops, courses, and books.

Health cover

We’ll make sure that you and your family have access to comprehensive health and hospital cover, no matter which country you live in.

Parental leave

Take time out to set up a new family, with 6 months of paid leave if you’re the primary carer, and 3 months if you’re secondary. You can use it flexibly, change between primary and secondary, and take the same leave for a still birth. We also keep paying super/401k for 6 months if you take unpaid leave.

Home office & coworking

Set yourself up with a great work environment, either at home or in a co-working space. With a budget for a desk and chair, and a new computer as well as any other tech, we’ll get you ready to work effectively in your environment. Even if you choose to work from home you will have access to a co-working budget for the days you want to connect with your wider community.

Wellness & paid time off

Take care of your health and wellbeing away from the screen, with 6 weeks of paid leave per year, the ability to take time out of work for fitness, and a yearly budget to spend on things like yoga, climbing, personal training, or a day at the zoo.

Working at Buildkite has given me the freedom to grow and flourish in all aspects of my life, personally and professionally. I’m proud to be a part of such a passionate and supportive team.
