SDE III - Mobile

Responsibilities:

• Architect and own high-performance, scalable mobile software from initial design to long-term stability and performance.
• Build production-grade Futter apps used by thousands of customers daily, across diverse industries and use cases.
• Leverage LLMs and AI tools to write, refactor, test, and debug code efficiently while implementing guardrails to reduce hallucination and boost reliability.
• Develop and maintain shared tooling, frameworks, and libraries that empower other engineers to build fast with confidence.
• Collaborate with designers, PMs, and platform/backend engineers to ship full-stack features.
• Measure and improve app performance, test coverage, code health, and build stability using modern dev tooling.
• Stay on the bleeding edge of AI/LLM technology, Futter best practices, and mobile architecture patterns and bring that knowledge back to the team.

Requirements:

• 4+ years of professional engineering experience (SDE II/III), including 3+ years in Futter/Dart.
• Demonstrated ability to architect maintainable, modular mobile systems.
• Mastery of Futter internals, widget lifecycle, performance profiling, and popular state management approaches (e. g., Provider, Freezed, Bloc, MobX).
• Experience working with Protobuf/gRPC in Dart.
• Track record of shipping and supporting large-scale mobile apps in production.
• Fluency in RESTful API design, mobile CI/CD, and Git-based workflows.
• Strong understanding of AI-driven development tools including prompt engineering, LLM-based code generation, test writing, and code review automation.
• Familiarity with hallucination mitigation strategies (e. g., code constraints, test scaffolding, embeddings, context injection).
• Excellent communication and collaboration skills, especially in distributed, asynchronous teams.
• Bonus: Contributions to AI tooling, Futter open-source libraries, or AI-enhanced mobile features.
