Senior Engineer - Test Analytics

Published on May 14, 2024

Buildkite is the fastest, most reliable, secure way to deploy and test code at any scale. Making developers happy and productive makes us happy, and we’re lucky to work closely with some of the best software teams in the world, including Airbnb, Shopify, Intercom, PagerDuty, and Basecamp.

We are a privately held company that values sustainable growth, transparency and work-life balance. We’re currently a distributed team of thirty and work remotely from Seattle, Vancouver, Perth, Sydney, Hobart, Adelaide, Kyoto, Oakland, Wellington, Berlin and Melbourne.

The Role

We’re building 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, Uber, Pinterest, Wayfair, Cruise, PagerDuty, Culture Amp, and Canva.

Test Analytics helps to make test suites faster and more reliable, reducing friction in developers' day to day work and making their working lives happier and more productive. We do this by identifying things like flaky and slow tests and showing trends over time of your suite, as well as providing the ability to deep dive into what happens when an individual test executes with tracing data for troubleshooting that test.

We’re looking for two Senior Software Engineers (Ruby On Rails) to help us build and launch a new test splitting product as part of Buildkite's Test Analytics ecosystem. Our mission is to create a world class test splitting tool that greatly reduces CI build times, and is easy and intuitive to use.
