Android Engineer

What You Will Be Doing

• Develop features and fix defects in the BioMobile™ Android application and Android BioSDK in Kotlin, following the MVVM architecture used across our mobile codebase. 

• Contribute to the Android BioHub Connect application used to set up and manage BioHub™ gateways over BLE, including Wi-Fi configuration for open, personal and enterprise networks. 

• Learn and support BLE communication with BioButton® wearables and BioHub gateways: scanning, connection management, and command and notification handling. 

• Help support the device-to-cloud data path into our AWS services. 

• Write and maintain unit and automated tests, and help keep CircleCI pipelines and mobile device farm runs healthy. 

• Work closely with the iOS engineer and senior Android engineers to keep feature behavior consistent across platforms. 

• Contribute to design documentation — Software Design Specifications, SOUP documentation, unit test coverage and verification records — as part of development rather than after it. 

• Participate in code reviews, design discussions and collaboration with quality, regulatory, hardware, firmware and cloud teams, and grow your skills through mentorship and hands-on work. 

What We Are Looking For

Requirements 

• Bachelor's degree in Computer Science, Engineering or a related field (recent graduates encouraged to apply), or equivalent practical experience. 

• 0–2 years of Android development experience, including internships, co-ops, coursework or personal projects; familiarity with Kotlin and Android Studio. 

• At least one Android application you have built and can discuss — published, academic or personal — ideally using MVVM or a similar architecture pattern. 

• Solid foundation in object-oriented programming, data structures and asynchronous programming (coroutines or similar). 

• Basic understanding of how mobile apps communicate with backend services (REST APIs, JSON). 

• Exposure to unit testing and version control with Git. 

• Genuine interest in Bluetooth Low Energy, wearable devices and connected health technology, with a willingness to learn quickly. 

• Familiarity with Python or another scripting language for tooling and log analysis. 

• Strong written and oral communication skills in English, and comfort asking questions and seeking feedback. 

• Able to work collaboratively on a small team, take direction well, and follow through on assigned tasks. 

Preferred 

• Internship, co-op or project experience in medical devices, healthcare or another regulated domain. 

• Awareness of healthcare software standards and regulations such as IEC 62304, ISO 13485 or HIPAA (no prior hands-on experience required). 

• Any hands-on BLE experience: scanning, connecting to a peripheral, or reading and writing GATT characteristics. 

• Jetpack Compose or other modern Android UI frameworks. 

• Exposure to CI tools (CircleCI, GitHub Actions) or mobile test automation frameworks such as Appium. 

• iOS or cross-platform familiarity, such as Flutter. 

• Interest in cybersecurity practices for connected devices. 

• Experience with cloud services such as AWS, even at a coursework or hobby level. 

• Experience working with embedded or hardware-connected projects (Arduino, Raspberry Pi, sensor kits, hackathons). 

• Familiarity with development tooling such as Jira and Confluence. 

• Contributions to open-source projects, hackathons or a portfolio demonstrating Android work.
