Software Engineer III, Core Experiences
Wikimedia FoundationSoftware Engineer III, Core Experiences
The Wikimedia Foundation is looking for two Software Engineer III’s to join the App Growth and Moderator Tools Engineering teams within the Core Experiences engineering group.
App Growth
The App Growth team has a clear and ambitious goal: make the apps the destination for knowledge lovers and grow our active readership. As a web full stack mid-career Software Engineer III supporting the Mobile Apps teams you will build features that create natural handoffs from the web to the app and landing users in exactly the right place — for example, prompting a reader to try a personalized reading list in the app, creating a game that is integrated within the apps as a webview; or when someone tries to edit there is a smooth hand off to the web editing experience.
This is not a native iOS or Android role. The role is focused on web-first product experiences, APIs, and platform integrations that can be reused across mobile web and native app surfaces; to help us scale features across platforms and create compelling features that deepen reader engagement and increase user retention.
To ensure there are enough opportunities to communicate, this role with the App Growth team needs at least four hours of your workday to occur between 14:00 UTC and 21:00 UTC.
Moderator Tools
On the Moderator Tools team, we build and improve tools for Wikimedia’s volunteer patrollers and administrators, improving their ability to review and take action on bad content across Wikimedia projects. Our focus right now is on exploring ideas for a centralized venue to identify moderator needs by advancing a unified personal Dashboard that supports the full reader-to-new-editor-to-new-moderator journey.
In order to see those bold ideas through, the team is looking for a software engineer III to join the team. As an engineer in the product and technology department, you will be responsible for building out components for our product user experiences in the Dashboard and other projects since the team maintains a handful of MediaWiki extensions and “off-wiki” projects related to The Wikipedia Library. In this role, you will work in a remote environment, where we value teamwork and a consensus-oriented approach. You get to write open-source code for collaborative experiences supporting over half a billion pages accessed per day
To ensure there are enough opportunities to communicate, this role with the Moderator Tools needs at least four hours of your workday to occur between 14:00 UTC and 20:00 UTC.
You are responsible for:
- Delivery and enablement - Supports delivery of initiatives. Breaks down complex features into tasks, anticipates risks and collaborates to resolve blockers.
- Implementation - Can successfully build moderately complex features and components with minimal support and suggests areas for architectural improvements.
- Production support - Takes ownership of bug fixes and production problems and communicates in a clear and timely way about impact and resolution.
- Quality, testing and observability - Designs and improves features with observability and testing as a core consideration. Instruments features that enable deeper analysis by Product Analysts. Contributes to healthier testing and software quality practices.
- Cross-functional collaboration - Supports team alignment by asking clarifying questions, reinforcing agreements, and coordinating their work with cross-functional partners. Facilitates team ceremonies.
- Prioritisation - Contributes meaningfully to planning. Helps scope work. Identifies risks across multiple sprints. Adapts as priorities shift.
- Culture and standards - Participates in code reviews, design discussions, and technical planning; shares knowledge proactively; and helps improve team development workflows.
- Operational Awareness -Thinks through how code affects usage and trust. Contributes to onboarding, documentation, and hiring efforts at the team level.
Qualities that are important to us:
- Continuous Learning - You adapt to ambiguity with desire to learn and discover by self-directing your learning in depth and breadth. You encourage and support learning in others. You proactively share knowledge to make it easier for others to contribute.
- Autonomy - You work autonomously on most tasks, whilst timely checking in with teammates and sharing workload when blocked.You balance contributing and receiving support within the team.
- Feedback - You share and receive thoughtful, actionable feedback with peers — both constructive and positive.
- Collaboration - You enjoy working with others to solve problems and are open to feedback. You actively share knowledge and experience; you offer guidance to help others grow.
- Accountable - You own your work end-to-end and help establish a culture of responsibility and follow-through. Thinks through implications of technical decisions, and reflects on whether delivered solutions meet the intended goals.
- Clear communicator - You can explain your ideas simply and communicate in a timely manner. You adapt your communication to different audiences across engineering, product, and non-technical audiences in both synchronous and asynchronous channels.
- Outcome-oriented - You connect your technical work to user value, team goals, and product outcomes. You can make pragmatic tradeoffs when the ideal technical solution is not the right immediate product choice.
Requirements:
- Bachelor's + at least 2 years or equivalent professional web application experience.
- Experience working with backend languages like PHP or Python and/or experience with front end languages particularly with Javascript frameworks.
- A demonstrated ability to deliver testable, user-friendly features in a collaborative team environment.
- Experience building responsive or mobile-first web experiences.
- Experience converting design mockups into functional components.
- Experience building features with observability and testing in mind.

Additionally, we would love it if you have:
- Experience working in a fully remote, internationally distributed teams or organizations team.
- Experience working with large, legacy codebases.
- A history of open source contributions
- Prior experience with MediaWiki or Wikimedia projects.
- Familiarity with Wikipedia / wikitext / markdown editing or content management systems (e.g., MediaWiki, Drupal, WordPress)
- Some experience with data science, machine learning, and/or AI (e.g., familiarity with prompt engineering, Jupyter notebooks experience, etc.)
- [For App Growth] Experience in launching and maintaining mobile applications, cross platform app frameworks, or building webview-wrapped experiences in native mobile apps.
- [For App Growth] Experience building mobile games or other interactive experiences.
- [For Moderator Tools] Experience with at least one Python framework, such as Django or Tornado.
