  • build and maintain publicly accessible metrics wherever possible.
  • monitor the quality and accuracy of data, alerting relevant teams where possible of discrepancies.

Position: Security Engineer, Infrastructure

Security Engineers develop and implement effective security practices to be engrained within the Infrastructure Team's work. A Security Engineer is responsible for:

  • building, designing, implementing and monitoring highly effective security processes and protocols that will affect how the Infrastructure team work.
  • analysing and prioritising incoming security alerts including CVEs and user reports.
  • working with Trust and Safety and the MediaWiki Team to ensure a collaborative and unique approach on security/privacy.
  • assisting with Security Reviews for MediaWiki extensions and Content Security Policy requests
  • leading on security incidents, including post mortem follow-up and liaising with Trust and Safety to establish impact and cause.

Team: MediaWiki, Site Reliability Engineering

The MediaWiki team is responsible for offering the MediaWiki core platform and MediaWiki extensions. They develop in-house extensions, maintain the latest stable version of MediaWiki core and extensions, handle the configuration and feature requests from the community and work with Wikimedia (upstream) and other third-parties.

Site Reliability Engineers support the delivery and maintenance of our virtualised and physical MediaWiki environment. As a Site Reliability Engineer, they are expected to monitor and maintain a wide range of software and services, ensure the uptime of the wider cluster and provide support to the MediaWiki Team in deploying to the infrastructure stack. Additionally they are responsible for:

  • maintaining the virtualised MediaWiki environment, physical hardware and services deployed to ensure routine security fixes are deployed and uptime is maintained.
  • performing day to day work as brief by the MediaWiki Engineering Manager.
  • triage and resolve incoming Phabricator tasks for the MediaWiki Team.
  • maintaining configuration deployment systems (Puppet).
  • taking control during incidents and working as a team to mitigate, resolve and prevent future outages.
  • assisting the Infrastructure Team as required.

Position: MediaWiki Engineer, MediaWiki

MediaWiki Engineers support day to day maintenance of the MediaWiki software stack, triage and resolving incoming requests for support and assist Software Engineers and Site Reliability Engineers in their work. A MediaWiki Engineer is also responsible for:

  • triaging and resolving incoming support requests from the community, internal teams, stakeholders and third party providers to ensure they are resolved in a timely manner.
  • maintaining the MediaWiki application stack, working with other teams where necessary to ensure the stack remains operational and performant.
  • keeping all software deployed up to date, arranging maintenance windows with and for other teams to maximise uptime.
  • supporting general operations of the service where possible and requested.

Position: Software Engineer, MediaWiki

Software Engineers develop code to improve the user experience of Miraheze users, build tools that allow communities to grow, and tools that support our valuable volunteers in managing a dynamic and active global community. A Software Engineer is responsible for:
