Check ourTech Radar for a live snapshot of our current stack.

The Role
We are looking for a versatile FlutterEngineer to join our Warsaw hub. You will architect and build cross-platform mobile applications moving fluidly between Flutter andReact Native.
We dont believe in one framework to rule them allwe use the right tool for the job. Currently that means high-performance Flutter apps for some products and React Native for others. You wont just be coding views; you will be defining how users interact with AI-driven backends and ensuring offline-first reliability.
We also believe the future of coding is AI-assisted. We expect you to leverage tools like Claude Code andCursor to move faster and focus on high-level architecture rather than boilerplate.

The Projects
You will be working on high-impact products immediately including:

: A comprehensive internal communication platform designed to connect companies with their decentralized workforce (frontline workers retail healthcare).1
AudioBreeze: An immersive application that generates dynamic audio soundscapes in real-time.
Tourism AI Assistant: A sophisticated chatbot and conversational interface developed for a major tourism corporation (confidential client).

What Youll Build & How

Architecture: Develop scalable mobile architectures using Flutter (Dart) and React Native (TypeScript).
AI-First Workflow: Utilize AI tools (Cursor Claude Code V0) to accelerate feature delivery refactoring and unit testing.
Native Performance: Build performant interfaces that respect platform specifics (iOS/Android) focusing on frame rates app size and battery efficiency.
Real-Time & Offline: Implement real-time data synchronization (WebSockets) and robust offline-first capabilities for users in the field.
Collaboration: Work in a hybrid setup with designers and backend engineers to define API contracts and product logic.

What You Bring

Versatility: You are not dogmatic. You have strong experience in either Flutter or React Native and are willing to master the other. (Ideally you are already comfortable with both).
TypeScript Fluency: When working in React Native you understand generics utility types and strict type safety.
AI Literacy: You are comfortable using AI coding assistants (Cursor Claude Code etc.) as a daily driver to enhance productivity.
State Management: Experience handling complex client-side state (e.g. Riverpod/BLoC for Flutter; Zustand/TanStack Query for React Native).
Engineering Standards: A pragmatic mindset toward CI/CD (Fastlane) automated testing and code quality.

Nice-to-Haves

Native Experience: Proficiency in Swift (iOS) or Kotlin/Java (Android) to write custom native modules when wrappers arent enough.
Experience interacting with GraphQL APIs.
Familiarity with Cloud Infrastructure (GCP/Azure).
Open-source contributions.

The Offer

Location: Hybrid role based in Warsaw.
Contract: B2B or Business Incubator - guaranteed load with 30 days notice period.
Rate: 25-40/h (approx. 6000/month gross) depending on skill level.
Perks:
- $77/month Medical & Sport budget.
- $100 Birthday bonus.
- $1000 Loyalty bonus (after 3 years).
- Annual Summer Camp (European cities/beach locations).
Growth: 3 dedicated education days/year budget for courses and conferences.
Warsaw Hub: Monthly team lunches spring events and year-end dinners.

Why mp

Because we use AI tools not just to build productsbut to evolve how we work.
Because we value output and impact over Jira tickets.
Because we are small enough to move fast but established enough to build things that last.
