The Wikimedia Foundation is looking for a Senior Site Reliability Engineer to support and develop the platform behind Wikipedia and other Wikimedia projects, ensuring high reliability and scalability of one of the world’s top-10 websites. This remote-first role involves operational leadership, automation, incident response, and collaboration with global engineering teams to advance the mission of free knowledge for all.
What You'll Do
- Performing day-to-day operational/DevOps tasks on Wikimedia’s public-facing infrastructure (deployment, maintenance, configuration, troubleshooting)
- Implementing and utilizing configuration management and deployment tools (Puppet, Kubernetes)
- Leading continuous improvement by automating the installation, configuration, and maintenance of services on our platform
- Work closely with product teams, helping them bring scalable functionality to our users by assisting in the architectural design of new services and making them operate at scale
- Participating in a 24/7 on-call rotation shared across the broader SRE team. This includes taking part in incident response, diagnosis, and follow-up on system outages or alerts across Wikimedia’s production infrastructure.
- Collaborating with a global, cross-functional team in an asynchronous communication environment
- Mentoring peers in your areas of technical and operational strength
- Ability and willingness to travel 1-2 times a year for in-person events and team meetings
- Most importantly, share our values and work in accordance with them
What We're Looking For
- 6+ years of experience in an SRE/Operations/DevOps role as part of a team
- Experience with shell and any scripting languages used in an SRE context (Python, Go, Bash, Ruby; we primarily use Python) and configuration management tools (Puppet, Ansible; we use Puppet)
- Experience with distributed caching systems, including their underlying algorithms and how to optimize their performance
- A thorough, protocol-level understanding of TCP/IP, HTTP, TLS, and DNS
- Experience with package management on Linux systems (we use Debian)
- Strong Linux system-level troubleshooting skills
- History of automating tasks and processes, identifying process gaps, and finding automation opportunities
- Strong English language skills (verbal and written) and ability to work independently, as an effective part of a globally distributed team working across multiple time zones
- Experience leading and participating in incident response and post-incident review rituals, with the goal of conducting root cause analysis and implementing preventive measures.
Nice to Have
- Experience with high-performance HTTP(S) caching-proxy software, such as HAProxy, Varnish (Vinyl), Apache Traffic Server, Envoy, or Nginx
- Experience with Linux kernel tuning for high-traffic loads
- Experience with the use, maintenance, and configuration of monitoring, metrics, and logging infrastructure (Prometheus, Grafana, etc.)
- Developing/contributing to Free and Open Source software, or being part of an open-source community (share your favourite pull requests!)
- Experience with LAMP stack technologies (PHP/HHVM, memcached/Redis) -- MediaWiki experience is a definite plus
- Experience with defining cross-team SLOs and their implementation
