Mobile App Engineer information

What does a mobile app engineer do?

A Mobile App Engineer designs, develops, tests, and maintains applications for mobile devices such as smartphones and tablets. They typically work with programming languages like Swift for iOS, Kotlin or Java for Android, and sometimes cross-platform tools like Flutter or React Native. Their responsibilities include ensuring app functionality, optimizing performance, fixing bugs, and updating apps to support new devices or operating system versions. Mobile App Engineers also collaborate with designers, product managers, and other developers to create user-friendly and secure mobile applications.

What are the key skills and qualifications needed to thrive as a mobile app engineer, and why are they important?

To thrive as a Mobile App Engineer, you need strong programming skills in languages such as Swift, Kotlin, or Java, along with a solid understanding of mobile UI/UX principles and a relevant degree in computer science or a related field. Familiarity with development frameworks (like React Native or Flutter), version control systems (such as Git), and experience with app store deployment are typically required. Problem-solving, attention to detail, and effective communication are vital soft skills in this role. These competencies ensure high-quality, user-friendly applications and efficient collaboration with cross-functional teams in a rapidly evolving tech environment.

What are some common challenges faced by mobile app engineers when working on cross-functional teams?

Mobile App Engineers often collaborate with designers, backend developers, product managers, and QA specialists to deliver seamless app experiences. A common challenge is ensuring clear communication across disciplines, especially when translating design concepts into functional mobile features or syncing backend APIs with app requirements. Navigating differing priorities and timelines between teams can also require effective negotiation and adaptability. Building strong relationships and proactively addressing misunderstandings are key to overcoming these challenges and delivering high-quality apps.

Senior Mobile App Engineer (React Native/iOS/Android)

Beacon Biosignals

Boston, MA • On-site, Remote

$170K - $190K/yr

Full-time

PTO

Posted 21 days ago

Key responsibilities

  • Develop cross-platform mobile applications using React Native and native iOS and Android 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 developed.

Job 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.

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.
