React Native Engineer

ITRex Group
Poland · Full-time · Mid-Senior
THE PLACE

ITRex - AI pioneers who build systems that actually work in the real world, not just in demos. We're 200+ people spread across the US and Europe, creating solutions for companies like P&G and Shutterstock. We keep it simple, build it right, and focus on what works.

THE PEOPLE

We're the kind of people who don't ignore messages in Slack, who jump in to help when you're stuck on a problem, and who offer solutions instead of blame when things go sideways. We believe in openness, accountability, and having each other's backs. No office politics, no hidden agendas - just people who care about doing good work together and supporting each other to get there.

Requirements

Your Responsibilities

  • Design and build advanced applications for the iOS and Android platforms using React Native
  • Collaborate with cross-functional teams to define, design, and ship new features
  • Leverage native APIs for deep integrations with both platforms
  • Optimize applications for maximum speed and scalability
  • Maintain and improve existing applications, ensuring strong performance across devices
  • Write clean, maintainable, and efficient code following best practices
  • Participate in code reviews, providing constructive feedback to team members
  • Stay updated with the latest trends and technologies in mobile development and propose new solutions as needed

What We're Looking For

  • 3+ years of experience in mobile development with a focus on React Native
  • Strong proficiency in JavaScript/Typescript
  • Experience with mobile app development lifecycle, including designing, testing, publishing, and maintenance
  • Understanding of RESTful APIs and integration with third-party libraries and services
  • Experience with Redux
  • Familiarity with Continuous Integration and Continuous Deployment (CI/CD) practices
  • Excellent communication skills and teamwork capabilities
  • English: Upper-Intermediate or higher

Nice-to-have:

  • Familiarity with native mobile development (Swift / Java)
  • Experience in crypto & blockchain development (e.g., wallets development)

Benefits

Why people stay

First, the foundation:

  • Remote flexibility: Work where and how you work best - we trust you to deliver
  • Fair compensation: Competitive salary + benefits that matter (medical, wellness, learning)

Then, the growth:

  • Ownership opportunities: See a problem worth solving? Own it. We back smart risks over bureaucratic safety
  • AI enhancement: We leverage AI to make you faster and stronger - complementing your abilities, not replacing them
  • Learning investment: English classes, professional development, well-being support
  • Career progression: Real paths up, not just sideways shuffling

Finally, the people:

  • Responsive teammates: No ignored Slacks, no "not my problem" attitudes
  • Supportive culture: When you're stuck, people help. When things break, we fix them together
  • Human connections: Regular meetups, tech talks, and actual relationships beyond work

Curious? We are too. Let's talk
