Sr Software Engineer - Mobile

We are seeking a highly experienced Senior Mobile Application Engineer to serve as a top-tier individual contributor on our mobile team. This role requires a hands-on engineer capable of designing, building, and delivering high-quality mobile applications at scale.

The ideal candidate is AI-first in mindset, deeply technical, and capable of owning complex initiatives end-to-end across Flutter, native mobile platforms, and platformized mobile architectures.

This is not a maintenance role — we are looking for a builder who raises the technical bar.

• Architect and implement scalable, high-performance mobile applications using Flutter.
• Design and integrate robust RESTful APIs.
• Contribute across both Android and iOS native codebases when needed (preferred).
• Work within and extend strongly platformized mobile architectures and shared frameworks.
• Write comprehensive unit, integration, and widget tests to ensure reliability, maintainability, and regression protection.
• Champion automated testing and quality-first engineering practices.
• Lead technical design discussions and drive best practices in architecture, testing, performance, and maintainability.
• Champion an AI-first engineering approach, leveraging AI tools to improve velocity and code quality.
• Identify and resolve performance bottlenecks, memory issues, and architectural weaknesses.
• Operate as a senior technical voice capable of owning initiatives independently.

• 7+ years of professional mobile development experience.
• Experience with Flutter (Dart), Unity / C#, Unreal / C++, Native Android (Kotlin/Java) and/or iOS (Swift/Objective-C) for production-grade applications.
• Strong experience writing and maintaining automated tests (unit, integration, and end-to-end).
• Solid understanding of REST API design, integration, and debugging.
• Strong familiarity with development workflows using:
  • Jira for work tracking
  • GitHub and GitHub Workflows for CI/CD automation
  • Crashlytics (or similar tooling) for production monitoring and debugging

• Deep understanding of mobile architecture, state management, dependency injection, and scalable design patterns.
• Proven ability to ship features independently and own large initiatives.
• Experience working in highly platformized or modularized codebases.
• Demonstrated commitment to high test coverage and engineering quality standards.
• Experience integrating authentication flows (OAuth, PKCE, etc.).
• Experience optimizing application startup, memory usage, and rendering performance.
• Proven ability to use AI tools (e.g., copilots, agentic workflows, LLM integrations) to increase development velocity and quality.
• Experience embedding AI-driven features into applications.
• Comfortable operating in an environment where AI-assisted development is expected.

• Innovation: Bring your creative ideas to the table and be part of a company that values out-of-the-box thinking
• Growth: Join a dynamic team with ample opportunities for professional and personal development
• Resideo provides employees with a comprehensive benefits package, including life and health insurance, life assistance program, accidental death and dismemberment insurance, disability insurance, retirement plans, vacation & holidays
