Senior React Native Engineer

Write code that delivers - literally.

At Package.ai, we’re reshaping the way retailers communicate with their customers - from the first chat on a website to the doorstep delivery and beyond. Our SaaS platform already powers over 100 retailers, orchestrating millions of conversations and deliveries each year.

Now we’re extending that impact into the hands of consumers through our mobile apps - complex, offline-first beasts that keep working even when the network gives up. These apps are mission-critical, powering real-world retail operations at scale.

We’re looking for a brilliant Senior React Native Engineer to become our in-house mobile authority. You’ll be the one everyone points to when anything “app” comes up. From architecture and offline sync to release management, you’ll own it all.

This is a remote contractor position based in Serbia.

If you’re passionate about mobile craft and want to shape the experience of our clients and end-users, this role is for you.

• Lead the architecture, development, and optimization of our React Native apps.

• Build reliable, offline-first experiences that survive even the worst Wi-Fi at your favorite café.

• Tackle advanced sync optimization challenges.

• Own the full lifecycle - from design and implementation to deployment, monitoring, and release management.

• Work closely with our founders and engineering team as the go-to mobile expert.

• Continuously research, evaluate, and introduce new technologies that make our apps faster, slicker, and just plain cooler.

• Confident and independent - you don’t wait for instructions, you write them.

• Passionate about mobile experiences - you care about pixels, not just pull requests.

• Impact-driven - you want to ship things that make real people happy, not just pass tests.

• Collaborative, curious, and maybe the kind of person who enjoys a good “dark mode vs. light mode” debate.

• 5+ years of experience in React Native development.

• Proven experience designing and implementing offline-first apps and sync architectures.

• Strong familiarity with mobile build, testing, and deployment pipeline.

• A sharp eye for mobile UX and design details.

• Passion for software engineering craftsmanship - clean code makes you smile.

• Excellent communication skills in English, both written and spoken.

You’ll join a small, world-class team solving meaningful, complex day-to-day problems at scale. Our platform already drives millions of deliveries and customer interactions, but we’re just getting started.

Here, you’ll have true ownership, fast feedback loops, and the chance to shape a product used daily by thousands of businesses and consumers.
