The Wikimedia Foundation is the nonprofit that hosts Wikipedia and our other free knowledge projects. We want to make it easier for everyone to share what they know. To do this, we keep Wikipedia and Wikimedia sites fast, reliable, and available to all. We protect the values and policies that allow free knowledge to thrive. We build new features and tools to make it easy to read, edit, and share from the Wikimedia sites. Above all, we support the communities of volunteers around the world who edit, improve, and add knowledge across Wikimedia projects.

You are responsible for:

• Cookbook / runbook implementation for common maintenance actions
• Incident response, diagnosis and follow-up on system outages or alerts
• Automation and streamlining of tasks as well as identifying process gaps
• Collaborating with a global and asynchronously communicating team (don’t worry if you have never worked remotely, we’ll help you get used to it)
• Mentoring peers in your areas of technical and operational strength

Skills and Experience:

• Strong experience with automation and configuration management tools such as Terraform, Ansible. Proficient in at least one programming language (Python,, Go, or similar).
