Software Engineer III – Mobile/Web
Stone & Company
• 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 a hypothesis-driven cycle requires that approach • Integrate REST APIs with a focus on contract, resilience, and observability from the start • Maintain disciplined contribution to 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: deployments, releases, and rollbacks • Actively participate in technical refinement, contributing to solution decisions from early phases • Work collaboratively with cross-functional teams (product, data, backend) • Contribute to the technical growth of more junior team members • Work with open or loosely defined scope with autonomy, proposing hypotheses and helping to structure solutions
Job Requirements
- Experience with mobile development (Android native, Flutter, or KMP/CMP — a big plus if you already have KMP/CMP experience)
- Familiarity with web development (HTML/CSS/JS, or frameworks such as React/Vue) — you don't need to be an expert, but you should be able to get things done
- Strong experience integrating APIs (REST, authentication, error handling, performance)
- Basic knowledge of systems architecture: how your app connects with the external world
- Familiarity with observability tools and a monitoring-driven culture
Benefits
- Health and Dental Plan
- Vitta Digital Hospital: access to a multidisciplinary medical team, therapists, and a health team available 24/7 for quick and convenient care
- Meal allowance and/or Grocery allowance
- Remote allowance + Initial setup (exclusive to remote positions)
- Flexible working hours
- Education Benefit — internal platform with access to books, podcasts, training, and video lessons for self-development (Studa and the StoneCo Library)
- Gympass
- Childcare assistance
- Profit Sharing (PLR)
- Life Insurance
- Transportation allowance (exclusive to on-site positions)
