Senior Mobile Developer
BRAINR
Remoto
Our mission is to give the people who make the food we love a better life at work, so that the world eats better. A world where the best food is made in autonomous factories, by people who love making it.
Profitable from day one, we’ve recently secured a record breaking €12.5M Seed Round, the largest in Portugal’s history, to take our mission global. And we’re getting there, because today over 30% of all meat production in Portugal is already managed by BRAINR.
Along the way, we’ve been recognized as the Best Factory Digitization Solution at Food 4 Future in Spain, selected for EUROPA’s 100 most promising startups, and named a Top Cloud Based MES Solution by Manufacturing Tech Insights.
What sets us apart isn’t just the tech. It’s the people. Our leadership team combines deep industry know how with world class tech expertise, giving you the chance to learn and grow faster than anywhere else.
The mission is massive. The ambition is real. And we need talent like you to bring our vision to every food factory on earth.
The Challenge
We’re looking for a Mobile Developer to join our Platform team and help maintain and evolve the shared tools and components behind BRAINR’s AI-powered factory operating system.
You’ll work on internal tools and frameworks, helping product teams build consistent web experiences. Your focus will be on keeping existing work moving while improving the reliability and reusability of our frontend foundations.
This is an opportunity to build on your frontend foundations, learn an established codebase, and grow your ownership with guidance from the team.
This role is based at our headquarters in Leiria, Portugal.
What You’ll Do
- Maintain and evolve our internal tooling and framework, and shared frontend components with support from the team.
- Build responsive, accessible interfaces and integrate backend APIs.
- Debug issues, write tests, and improve usability and performance.
- Collaborate with Product and Design, learning through code reviews and feedback.
- Take part in knowledge transfer, document what you learn, and gradually take ownership of existing frontend work.
- Mobile moves closer to full SDUI support, with fewer custom implementations.
- Factory workflows become smoother and more reliable, with measurable performance gains.
- Reusable, documented mobile capabilities give product teams greater autonomy.
You may be a great fit if you have:
- 4+ years of experience delivering production mobile applications with React Native and TypeScript.
- Strong foundations in reusable components, state management, navigation, and API integration.
- Hands-on experience profiling, debugging, and optimizing mobile performance.
- Good testing practices and familiarity with Git, CI/CD, and mobile releases.
- Ownership of features and a collaborative approach to technical decisions and knowledge sharing.
- Fluency in English, spoken and written.
- Familiarity with AI Augmented engineering practices.
- Experience with native Android integrations or resilient mobile experiences under variable connectivity.
- Familiarity with configurable interface builders or server-driven UI.
- Experience with data-rich interfaces, complex forms, or B2B operational tools.
