What the job involves

We’re looking for an experienced Senior iOS Developer to help us maintain and evolve our UIKit-based iOS app while shaping its migration to SwiftUI + Combine
Our current codebase uses RxSwift, SnapKit, and MVVM, but we’re planning a progressive shift toward more modern tooling — and we’re open to candidates with expertise in either approach
Your work will directly impact how people interact with their mental and emotional wellness through real-time neurofeedback
You’ll build tech that’s used by clinicians, researchers, and individuals around the world to improve lives in measurable ways
Build and maintain features using Swift, MVVM, and either UIKit or SwiftUI
Contribute to the migration from RxSwift + SnapKit to Combine + SwiftUI
Help define the technical direction of the app’s architecture and UI layer
Collaborate with cross-functional teams to ship clean, high-performance code
Optimize app performance and memory usage, especially around embedded content
Integrate shared libraries and third-party modules, including C++ and WebView-based components
Participate in sprint planning, reviews, retrospectives, and technical design sessions

Our take

Meditation and sleep have become billion-dollar businesses through the increase of sleep and relaxation technology and apps. InteraXon, the owner of Muse, is a late-stage venture company in the neurotechnology space with a brain and biosensor platform of hardware and software products such as sleep headbands, a sophisticated data-cloud infrastructure, and the largest database of brain data in the world.

The ability to benchmark and measure progress through wearable devices has been particularly attractive not only to consumers but also to leaders of corporate wellness programs, mental health professionals and business and athletic coaches.

In 2022, the company announced an upcoming launch of a VR Software Development Kit with an aim to support strategic partnership opportunities for innovations in brain health, leveraging their biosensing technology in VR and AR applications.
