Senior Software Engineer - Growth at Wikimedia Foundation

The Wikimedia Foundation is looking for product software engineers to join the Growth team, reporting to product engineering management. As a product software engineer, you will be responsible for software engineering for our product user experiences. In this role, you will work in a mostly-remote environment, where we value teamwork and a consensus-oriented approach. You get to write open source code for collaborative experiences supporting over a half a billion pages accessed per day, and you get to do it at a place that believes we're all more successful when everyone has a good work-life balance.

On the Growth team, we work to help new people start editing Wikipedia by introducing new editing workflows that are a fit for more people on more devices all around the world. We build a cohesive experience for newcomers, helping them find a place in our communities, connect with others, and start contributing their knowledge. Our main projects have focused on machine-learning driven task recommendations and volunteer mentorship.

You are responsible for:

• Improving the Wikipedia new contributor experience by building new functionality primarily in the GrowthExperiments extension and fixing bugs for code that our team maintains
• Collaborating with product managers, designers, and other teams on shared projects
• Writing multilingual and accessible software using JavaScript, PHP and CSS
• Building on top of existing APIs in our ecosystem and writing new ones when needed, working with other engineers to reduce technical debt
• Instrumenting components to monitor user behavior and performance characteristics

Skills and experience:

• 5+ years related professional experience in frontend and backend programming
• Experience building user-friendly features and software components using well-documented and readable code
• Focused software engineering: you enjoy writing unit and integration tests, proactively addressing security and code review feedback, and thoughtfully balancing architectural trade-offs

Qualities that are important to us:

• A desire to make meaningful contributions to knowledge equity, free culture, and open access
• An emphasis on communicating clearly in both synchronous and asynchronous channels
• Interest in mentoring, or teaching and sharing about technical knowledge

Additionally, we'd love it if you have this:

• Experience working with internationally distributed teams or organizations
• Familiarity with Wikipedia / wikitext / markdown editing or content management systems (e.g., MediaWiki, Drupal, WordPress)
• Experience working with projects or communities in languages other than English
• Experience working with large, legacy codebases
• Bachelor's in a relevant field or equivalent experience
