Senior Platform Engineer

ABOUT FOUNDATION Foundation is responsible for the technical base that Knowunity's product teams build on. Our work is measured by its effect on the rest of engineering: reliable systems, sound architecture, and tooling that let product teams focus on their features rather than the underlying infrastructure. Our areas of ownership: - The Flutter mobile app foundation - shared components and design system, app architecture, state management, and performance. - The core backend in Go - the shared services and conventions that product features are built on. - Infrastructure and delivery - CI/CD, store distribution, release tooling, and the feedback loops between writing code and shipping it. - Developer experience - the internal tooling and standards that keep the wider organisation productive. - Agentic and AI infrastructure - how AI tooling is integrated into our codebase and workflows today, and how it will factor into the product over time. We are looking for a Mobile Platform Engineer to help shape and maintain this foundation. The role's focus is the mobile app, but we expect genuine interest in the full scope of Foundation's work - the team's value comes from its leverage across all of these areas, not from any single feature. Responsibilities - Mobile foundation. Own the core of our Flutter app: shared components, the design system, performance, and tooling. - Architecture. Define how we build features - the patterns we use, how we manage state, and how the app integrates with backend services - and guide product teams in applying them. - Developer experience. Improve the end-to-end developer workflow, from CI/CD and store distribution to internal tooling and faster feedback loops. Remove the recurring friction that slows other teams down. - Agentic and AI infrastructure. Integrate AI tooling into our codebase and workflows, and help determine its role in the product. A research background is not required, but a serious interest in agents as an engineering disc
