Mobile Developer

Hey, we’re BRAINR.

At BRAINR, we’re reshaping how food factories operate. We’ve built a next-generation, AI-powered cloud MES (Manufacturing Execution System), and we’re growing fast.

Our platform helps food manufacturers manage everything from raw material reception to production planning, warehouse operations, and dispatch, with custom quality control and full traceability. BRAINR connects people, machines, and sensors so that critical decisions can be made in real time — smarter, faster, and with greater impact.

The challenge

As we continue expanding our product, we’re looking for a Mobile Developer who’s passionate about building high-quality mobile experiences using React Native and TypeScript.

You’ll help us bring complex industrial operations to life on mobile - making them clear, fast, and usable in challenging factory environments. It’s a hands-on role with space to grow and a real opportunity to shape the mobile experience of our platform from the inside out.

What You'll Be Doing

In your day-to-day, you’ll:

• Build and maintain high-performance, scalable, and responsive React Native applications
• Translate UI/UX designs into clean, reusable components
• Collaborate closely with backend developers, designers, and QA engineers
• Integrate REST APIs and ensure smooth data flow across the app
• Write clean, testable code with unit tests using Jest or similar tools
• Debug, monitor, and optimise app performance
• Contribute to agile workflows, including sprints, planning, and code reviews
• Document your work and help maintain development best practices
