• A customer-facing app that gives users real-time visibility and control over their myenergi devices (zappi, eddi, libbi, harvi, etc.).

• An installer-focused app used by professional installers to connect to our devices via Bluetooth for setup, configuration, and diagnostics.

You’ll work as part of a small, agile team with real ownership over product features and UX improvements. This is an opportunity to work on meaningful software that integrates closely with custom hardware and contributes to a more sustainable future.

• Build, maintain, and iterate on our two React Native mobile apps for iOS and Android.

• Work closely with product owners, designers, firmware engineers, and QA to deliver features from concept to release.

• Integrate with Bluetooth (BLE) APIs to support device configuration via the installer app.

• Collaborate on API integration for real-time energy data, settings management, and device control.

• Write robust, maintainable, and well-tested code.

• Identify and resolve performance bottlenecks, bugs, and UI/UX inconsistencies.

• Participate in regular code reviews and help shape best practices across the mobile team.

Qualifications & Experience:

• 5+ years using React Native in production apps.

• Strong skills in JavaScript and TypeScript.

• Experience building and maintaining cross-platform mobile apps (iOS and Android).

• Familiarity with Bluetooth Low Energy (BLE) integrations in React Native (or willingness to learn).

• Experience integrating RESTful APIs and handling asynchronous data flows.

• Version control with Git and familiarity with standard CI/CD processes (e.g. CircleCI).

• Experience delivering clean UI’s and user experience best practices.

• Good communication skills and a collaborative mindset.

Nice to Have:
• Experience working with native modules (Swift, Kotlin).

• Familiarity with BLE libraries.

• Testing tools like Jest.

• Previous experience in IoT, smart home, or hardware-connected apps.

• Understanding of energy systems or EV charging tech.
