Job Description
Software Engineer III – Mobile/Web
Stone
• Develop and evolve features in our app using Kotlin Multiplatform / Compose Multiplatform (KMP/CMP) as the primary technology • Build and maintain webview initiatives, contributing to web development when hypothesis cycles require that approach • Integrate REST APIs with quality, considering contract design, resilience, and observability from the start • Maintain disciplined contributions in a shared repository (monorepo or unified structure): coding conventions, code review, inline documentation, and CI/CD • Implement automated tests that validate the product end-to-end, not just isolated units • Use observability (logs, metrics, tracing) to monitor application health and drive investigations • Participate in the full delivery cycle: deploys, releases, rollbacks • Actively participate in technical refinement, contributing to solution decisions from early stages • Work collaboratively with cross-functional teams (product, data, backend) • Contribute to the technical growth of more junior team members; work autonomously with open or loosely defined scope—formulating hypotheses and helping to structure solutions
Job Requirements
- Experience with mobile development (native Android, Flutter, or KMP/CMP — huge bonus if you already have KMP/CMP experience)

- Strong experience integrating APIs (REST, authentication, error handling, performance)
- Basic knowledge of systems architecture: understanding how your app connects with external systems
- Familiarity with observability tools and a monitoring-oriented culture
