Summary Generated by Built In

Beacon Biosignals is transforming precision medicine for the brain, from clinical development to clinical care. For Life Sciences partners, we offer the leading at-home EEG platform for clinical development of novel therapeutics for neurological, psychiatric, and sleep disorders. Our Diagnostics business is building the most comprehensive at-home platform for precision diagnostics, combining EEG and cardiopulmonary signals to deliver reimbursable assessments for sleep and central nervous system disorders. Together, we're changing the way patients are diagnosed and treated for any disorder that affects brain physiology.

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.

Beacon's robust asynchronous work practices ensure a first-class remote work experience, but we also have in-person office hubs located in Boston and New York. For this position we will consider candidates based anywhere in the US Eastern time zone.

What success looks like:

As part of our small, mission-driven Mobile Apps Team, you will:

  • 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.
What you will bring:

You’ll be a great fit if you have:

  • 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

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.
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.
 
At Beacon, we've found that cultural and scientific impact is driven most by those that lead by example. As such, we're always seeking new contributors whose work demonstrates an avid curiosity, a bias towards simplicity, an eye for composability, a self-service mindset, and - most of all - a deep empathy towards colleagues, stakeholders, users, and patients. We believe a diverse team builds more robust systems and achieves higher impact.

What We Do

Brain monitoring is not easily accessible, interpretable or actionable. We're going to fix this, and we'd like you to help. With improved access to brain data and the right tools to act on it, clinicians could intervene in real-time, match life-altering therapies to the patients they benefit most, and treat previously untreatable neurological and psychiatric diseases. Beacon is building an interdisciplinary and uniquely talented team to implement this future.

Why Work With Us

We value curiosity and innovation. We approach problems like research - problems are an opportunity to learn something new and improve upon an outcome.
