Software Engineer, Mobile

Software Engineer, Mobile

Location: Antwerp (preferred) OR Amsterdam (secondary)

Experience: 3–5 years of experience in mobile software engineering

This is where mobile engineering meets connected product innovation. We built Loop by going all in from day one. You’ll build and maintain mobile applications that connect directly with our hardware products, owning features end-to-end across iOS, Android, and React Native. All yours. If you've mastered mobile development across native and hybrid environments and you're ready to break the rules that no longer work, this is where you do it.

You step into ownership. You move fast and take responsibility for what you build. You focus on work that matters, not on noise that slows things down. You are responsible for delivering robust, user-friendly mobile applications, integrating with firmware and backend systems, and ensuring reliable BLE communication and scalable mobile architecture.

• You own cross-platform mobile feature development end-to-end across iOS, Android, and React Native
• You implement and maintain BLE connectivity with hardware devices, ensuring reliable communication
• You collaborate closely with Firmware, Hardware, Product, and UX teams to deliver seamless user experiences
• You contribute to app reliability through testing, performance tuning, and release operations
• You leverage AI development tools to accelerate delivery while maintaining quality and security
• You build scalable mobile architecture using modern design patterns and frameworks
• You support CI/CD workflows and production releases across app stores

• Wait for endless approvals
• Hide behind processes
• Cruise quietly in the background

We look for people who think big, stay curious, and aren’t afraid to go all in to make things happen. You’ll succeed by delivering reliable, high-quality mobile features, making sound architectural decisions across platforms, and ensuring strong integration between mobile apps and connected hardware.

• You bring at least 3–5 years of experience in mobile software engineering
• Proficiency in Swift, Kotlin, and React Native, across native and hybrid architectures
• Strong understanding of BLE protocols, mobile architecture patterns, and release workflows
• You work independently and know when to involve others
• You’re comfortable with change and ambiguity
• You know when work is ready to ship, and when it can evolve
• You want your work to matter, not just exist

• Wait for direction instead of taking initiative
• Mistake activity for impact
• Feel uneasy when things are still taking shape
• Prefer alignment meetings over decisions
