Our six core values define our distinct culture, and our dedication to in-person collaboration sets us apart. About the Role We are looking for Principal Software Engineers to join us and play a key role in the design, build and testing of our secure, robust and scalable web hosting and data platforms. Our platform is a layer on top of core Open Source technologies such as Kubernetes, Istio, Airflow, dbt, running in Public Cloud. It is the glue that allows our teams to deploy into production environments 100s of times per day with the least amount of friction possible. As a Principal Software Engineer, you will work on all aspects of software engineering, from frontend and backend to infrastructure scripts and CLI's. It's important our systems stay up. You'll be working on systems designed to tolerate failure. It's equally important we know quickly when things go wrong, so you'll be working on monitoring and alerting systems too. We believe all infrastructure should be written as code, so it is testable and repeatable. You'll work with tools like terraform, helm, Kubernetes to make this happen. Problems come in all shapes and sizes, so you'll be expected to debug core platform and infrastructure issues, as well as consulting with product teams to help solve problems that span into the application domain too.
