[Hiring] Senior Mobile App Engineer @Beacon Biosignals

Role Description

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.

What success looks like:

• 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.

Qualifications

• 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.

Requirements

• Bonus points if you've 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.

Benefits

• The salary range for this role is $170,000 – $190,000.
• Salary ranges are determined using current market compensation data for this role and adjusted based on experience, skills, and location.
• The base salary is one component of the total compensation package, which includes equity, PTO and other benefits.
