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 freelance 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 features.
The engagement
-
Contract basis, open to full-time or part-time weekly commitment depending on your availability.
-
Initial engagement with scope to extend based on fit and pipeline of work.
-
You'll plug into an existing team, so we're looking for someone who can get productive quickly and work independently with light coordination.
