Description

Design and build high-performance features in Flutter/Dart for a large-scale consumer mobile app.
Maintain and extend the native calling stack, including SIP clients, audio handling, and CallKit/ConnectionService integration in Kotlin and Swift.
Own features end-to-end within a feature-first clean architecture using Bloc/Cubit, repositories, and immutable state.
Write and maintain business logic with 90%+ unit test coverage and strong deterministic testing practices.
Work within a melos-managed monorepo with 100+ packages and a strict dependency hierarchy.
Monitor app releases using Crashlytics and analytics, investigate call-quality and stability issues, and improve performance.
Contribute to mobile architecture decisions, package design, and migration of legacy patterns to the current architecture.
Collaborate with product managers, backend engineers, QA, and designers on cross-functional feature delivery.
Improve the engineering toolchain, including GitHub Actions CI/CD, automated releases, diff-coverage gates, and code-quality automation.

Requirements

5+ years of experience building large-scale mobile apps, including 3+ years with Flutter.
Strong proficiency in Flutter/Dart and the Flutter ecosystem, including Bloc/Cubit or comparable state management, asynchronous programming, isolates, code generation, and dependency injection.
Hands-on experience with native mobile development in Kotlin/Android and/or Swift/iOS.
Experience integrating native code with Flutter via platform channels.
Solid understanding of clean architecture, modularization, performance optimization, and mobile security best practices.
Strong testing culture with unit and bloc testing, mocked collaborators, deterministic tests, and coverage gates.
Experience with the full mobile development lifecycle, including Git, CI/CD pipelines such as GitHub Actions, code signing, and deployment automation to App Store and Google Play.
Upper-Intermediate English or higher.
Experience with VoIP or real-time communication technologies such as SIP, WebRTC, CallKit, Telecom framework, push-triggered call handling, and audio session management is a plus.
Experience working in large monorepos with tools such as melos or Mason is a plus.
Knowledge beyond the mobile stack, such as backend, infrastructure, or observability, is a plus.
Domain experience in telecom, fintech, or regulated consumer products is a plus.

Benefits

Remote B2B work opportunity for Georgia-Moldova or on-site employment for Belarus-Moldova.
Stable long-term role with growth perspective.
Competitive salary with annual performance reviews.
Really good hardware provided.
Continuous learning and career growth opportunities.
Compensation for professional training, seminars, and conferences.
