Senior Software Engineer, Core Experiences
About the role
Senior Software Engineer, Core Experiences
Summary
The Wikimedia Foundation is looking for a Senior Software Engineer to join the App Growth team within the Core Experiences engineering group.
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 Senior Software Engineer 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.
Important: We are a fully remote team at a global organisation. To ensure there are enough opportunities to communicate, this role needs at least four hours of your work day to occur between 14:00 UTC and 21:00 UTC.
You are responsible for:
- Delivery and enablement - Consistently leads the team in the delivery of medium complexity initiatives (with support) from technical discovery through delivery. Breaks down initiatives into features, drive estimation and manage scope. Identifies risks early, and helps the team make pragmatic tradeoffs across quality, velocity, maintainability, and user impact.
- Frontend Implementation - Improving the mobile Wikipedia product experiences that serve a global, multilingual audience across web and app surfaces. Leads system design for medium-sized projects and can design and build accessible, adaptable, scalable components.
- Backend Implementation - Takes ownership of creating RESTful APIs, from schema and contract design through to monitoring and iteration, to serve simple but scalable data pipelines to mobile and web client experiences at scale. Ensures pipelines and APIs remain simple to consume, reliable to operate, and straightforward to evolve over time.
- Quality, testing and observability - Consistently builds and improves systems & software that is easy to test, observe and debug. Instruments features that enable deeper analysis by Product Analysts.
- Cross-functional collaboration - Partners with product managers, designers, analysts, and native app engineers to shape pragmatic solutions that balance user needs, technical constraints, platform expectations, and delivery timelines.
- Prioritisation - Proactively identifies high-impact technical opportunities and risks across a quarter, partners with the team to shape priorities and sequencing. Actively keeps the team aligned on outcomes, capacity, and shared goals.
- Mentorship - Actively supports the growth and success of others. Mentors engineers through thoughtful code review, technical design, pairing, delegation of meaningful ownership, and modeling strong engineering judgment. Encourage team mates to ask questions and raise concerns.
- Culture and standards - Raises team standards in code review, technical design, testing, documentation, accessibility, observability, and decision-making - fostering transparency, empathy, and collaboration.
- Operational Awareness - Plans work with awareness of downstream or upstream effects. Actively supports hiring and onboarding.
