Role Summary

We’re looking for a Senior React Native Software Engineer to join our growing mobile team. You’ll help develop and maintain two key mobile apps:

• 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.

Key Responsibilities

• 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.

Required Qualifications and 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.
