Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Own and maintain the core Flutter mobile foundation, including shared components, design systems, and app architecture. Improve developer experience by optimizing CI/CD pipelines and integrating AI tooling into workflows.
Requires several years of experience delivering production software at scale with multi-year expertise in Flutter and Dart. Must have solid mobile DevOps experience and a strong interest in AI as an engineering discipline.
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.
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.
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.
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 discipline is.
Maintenance and reliability. Alongside new work, keep the existing foundation healthy and dependable, so product teams can build on it with confidence.
Several years of experience delivering production software at scale, ideally including responsibility for the architecture of a mobile application.
Strong, multi year experience in building mobile apps with Flutter and Dart.
Solid mobile DevOps experience - CI/CD, store distribution, and release management.
A genuine interest in AI as an engineering surface; curiosity matters more than formal background.
A preference for improving the systems that slow others down. You reason clearly about trade-offs, communicate effectively across teams, and take satisfaction in work whether or not your name is attached to a shipped feature.
