React Native Software Developer at Kalogon Melbourne, FL

Software Development for Hardware Products

Kalogon, a smart seating startup based in Melbourne, FL, seeks a React Native Software Developer to help ensure our iOS and Android applications meet the needs of customers who use our connected hardware products across all of our product lines. The ideal candidate will have experience working with hardware products, understanding and contributing to overall software architecture, and be nimble and collaborative across teams.

• Contribute to the mobile codebase end-to-end for iOS and Android.
  • Maintain and lightly extend our existing React Native (Type Script) code.
  • Work with our team to develop new apps to supersede legacy solutions.
• Define long-term architecture.
  • Make structural decisions today that keep the app healthy, performant, and extensible for years.
  • Focus on dependency-light, performant, and maintainable designs.
• Integrate with hardware over BLE.
  • Handle pairing, data transfer, and OTA updates with reliability and clear user feedback.
• Design and build great experiences.
  • Work closely with Product, Marketing, and Design to ship polished, cohesive UI/UX.
• Collaborate.
  • Work within a small engineering team, mentor peers, and communicate trade-offs to non-engineers.

• 7+ years professional software development, including multi-year stewardship of at least one shipped product.
• React Native & Type Script (enough to debug, patch, and ship updates).
• Mobile UX / UI: proven track record of designing and delivering polished interfaces on iOS and/or Android.
• Project Architecture: demonstrated ability to make foundational technical choices that scale over multiple releases.
• BLE: practical experience with Bluetooth Low Energy on either platform.
• Cross-team collaboration: turning feedback from marketing, sales, and design into product improvements.

You must share examples of past work (Git Hub repos, downloadable apps, etc.) to apply; provide concrete examples (screens, code, or portfolio) that show your design sensibilities.

• Rust — especially if you’ve used Rust for mobile via Rust-based UI toolkits or shared libraries.
• C, C++, Python for miscellaneous tooling and project context.
• Native iOS (Swift) or Android (Kotlin/Java) modules and bridging.
• Embedded / microcontroller firmware exposure (OTA workflows, BLE GATT design).
• HIPAA certification or experience with HIPAA compliance.

This is a full-time role based in the Kalogon offices in Melbourne, Florida.
