At Buildkite, our mission is to unblock every developer on the planet. We’ve rethought how software delivery 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. Empowering customers to self-host agents with our renowned hybrid architecture, we seamlessly orchestrate millions of mission-critical Continuous Integration (CI) jobs daily across any operating system, any cloud, and any environment with unmatched precision.

The Role

We’re looking for a Senior Software Engineer (Ruby on Rails) to help shape the future of Buildkite’s most exciting new products: Hosted Agents and Mobile Delivery Cloud (MDC).
