Site Reliability Engineer (Core Platform Team)
Job Posted on: Sept. 12, 2019
Job Type: Full-time
Experience Level: Mid-Level
The Wikimedia Foundation is looking for a Site Reliability Engineer to join its Core Platform Team. This role will directly support our application platform serving the world’s favorite encyclopædia to millions of people around the globe. Wikipedia and its sister projects are powered strictly by Free and Open Source software, with MediaWiki at its core, surrounded by an ecosystem of microservices in PHP, NodeJS, Python, and Go.
We are a distributed and diverse team of engineers with a drive to explore, experiment, and embrace new technologies. During the past few years we have been transitioning our platform from a monolith to a hybrid microservices architecture, and started migrating our microservices onto Kubernetes running on bare metal. This work underpins our goals of modernizing our platform to help build and support the future work of the WMF, its sister projects and the global community.
If you find what we do interesting, if you are up to the challenge of improving the reliability and delivery of one of the Internet’s top 10 websites, and you enjoy the idea of working with a globally distributed team, you might be just the person we need. Come as you are!
You are responsible for:
- Ensure smooth and reliable operation of the MediaWiki application platform, the surrounding ecosystem of microservices, and their dependencies (Memcached, Cassandra, Kafka, etcd, …)
- Perform platform transformations and migrations towards modernized infrastructure (HHVM to Zend PHP7, bare metal deployments to Kubernetes clusters, active/active multi-data center support, etc.)
- Bring your creativity to improve our current infrastructure and introduce new automation where needed
- Support new code/feature deployments
- Troubleshoot, debug and follow-up on emerging issues in our application stack and its surroundings
- Interface between the Core Platform Team and the WMF’s SRE team
- Implement and utilize configuration management and deployment tools (Puppet, Kubernetes)
- Assist in the architectural design of new services and making them operate at scale
- Monitoring of systems, services and service clusters, optimization of performance and resource utilization
- Incident response, diagnosis and follow-up on system outages or alerts across Wikimedia’s production infrastructure
- Share our values and work in accordance with them
Skills and Experience:
- 3+ years experience in an SRE/Operations/DevOps role as part of a team
- Experience in supporting complex web applications running highly available and high traffic infrastructure based on Linux
- Experience working with PHP, Nodejs and Go applications
- Comfortable with configuration management and orchestration tools (Puppet, Ansible, Chef, SaltStack, etc.), and modern observability infrastructure (monitoring, metrics and logging)
- Aptitude for automation and streamlining of tasks
- Comfortable with shell and scripting languages used in an SRE/Operations engineering context (e.g. Python, Go, Bash, Ruby, etc.)
- Good understanding of Linux/Unix fundamentals and debugging skills
- Strong English language skills and ability to work independently, as an effective part of a globally distributed team
- B.S. or M.S. in Computer Science or equivalent in related work experience
Qualities that are important to us:
- Experience managing MediaWiki installations is a major plus
- Track record of open source contributions is highly appreciated
- Familiarity with core distributed systems concepts
- Familiarity with modern distributed container cluster management systems (Kubernetes, Docker Swarm, Mesos, …)
- Low level systems troubleshooting and debugging (CPU/memory profiling, C/C++ experience, in-depth Linux knowledge)
- Experience with advanced distributed storage and database systems (Swift, Ceph, Cassandra, etc.)
- Remote work experience with a highly distributed team
- Familiarity with RFC2549 or similar protocols
