About Us

We build tools to help the best software teams stay happy and productive. We’ve rethought how CI/CD should work and have built a platform that is fast, reliable, secure, and is able to scale to the needs of the most demanding high-growth tech companies including Shopify, Pinterest, Wayfair, Cruise, PagerDuty, Culture Amp, and Canva.

Buildkite is a differently shaped company that values work-life balance and supports staff to work the ways that make sense for them. From the beginning, our goal has been to build a company that is people-centered, supportive and just a little bit weird 💚

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 and phone every 24 months. We’ll also cover the cost of plants, art, or anything else you need to set yourself up with a beautiful and productive work environment.

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.

Profit share & ownership

Share in the company’s success, and have a stake in what you’re helping to build. Everyone on the team receives a percentage share of the company profits each quarter, and an equity stake through our employee share program.

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.
