Company mission
To improve human health by enabling rapid, targeted interventions through advanced brain analytics.
Role
Who you are
- 8+ years of experience in mobile development (native iOS/Android and/or React Native)
- Experience working with BLE, sensor integration, or health data streams
- A product mindset — you care deeply about UX, edge cases, and performance
- Familiarity with our tech stack (TypeScript, React Native, Swift, Kotlin, Expo, GitHub)
- Strong communication skills and comfort working in a collaborative, async environment
Desirable
- Worked with medical devices, EEG, or wearables
- Integrated BLE peripheral devices into iOS and/or Android applications
- Written native code extensively for either iOS or Android, in addition to React Native
- Worked on apps for clinical trials, patients, or in some other regulated environment
- Contributed to open source mobile or BLE projects
What the job involves
- As a Senior Mobile App Engineer, you’ll help power Beacon's mission by building cross-platform apps that interface with our EEG headbands and other wearables to capture high-fidelity data and enable seamless experiences for patients and clinicians
- This isn’t just another app — you’ll be crafting tools that help unlock insights into neurological, psychiatric, and sleep disorders, with the potential to improve lives at scale
- Develop our React Native mobile applications and our native iOS and Android BLE device SDKs
- Design and implement UX workflows for clinical trial participants and at-home diagnostic patients
- Own the user experience, app performance, reliability, and observability of the apps and features you develop, leveraging feedback from real users in a diverse set of use cases and environments
- Partner with our Devices team, other Platform teams, and product designers to develop user-centric mobile app capabilities that are deeply integrated with the rest of Beacon’s product ecosystem
- Help shape the roadmap and technical direction of our mobile platform
- In your first 3–6 months, you might:
- Build a new in-app feature to validate EEG signal quality before data capture
- Improve BLE pairing and reconnection reliability across both iOS and Android
- Streamline onboarding for new patients and trial participants to help make our devices easier to use than ever
- Deploy new features to help our Clinical Operations team track compliance
Our take
The brain has long been considered one of the most mysterious fields of medicine - and psychiatric and neurological diseases therefore one of the least understood. Better access to real-time brain data, however, could change this and that’s exactly what Beacon Biosignals is hoping to deliver.
Beacon Biosignals has developed an AI-powered EEG platform designed to better measure and understand brain activity. Its technology includes a lightweight wearable headband that tracks brain signals during sleep and at home, feeding huge amounts of real-world data into machine-learning models. The aim is to help researchers analyze brain activity faster, identify new biomarkers, and improve the development of treatments for neurological and psychiatric disorders.
The company recently raised major funding and acquired home sleep testing specialist CleveMed as it expands its AI-powered brain health platform. Its FDA-cleared wearable headband is already being used in more than 40 clinical trails studying conditions like depression, Alzheimer's, Parkinson's, and sleep disorders. By collecting millions of hours of brain activity data, Beacon hopes to help researchers detect diseases earlier and better understand how the brain changes over time.
