Principal Engineer, Software Development (Mobile)

Design and develop Android (Java/Kotlin) & iOS (Swift/Objective-C) mobile applications that connect to medical devices via BLE, ensuring secure and reliable data transmission. Collaborate with developers, QA, clinical, and hardware teams to create consistent and compliant cross-platform experiences. Implement BLE workflows including device discovery, secure pairing, bonding, characteristic interactions, and firmware updates. Implement health, fitness, and sensor integrations (e.g., HealthKit, Google Fit, Samsung Health APIs) Write clean, testable, and well-documented code following medical device software standards (e.g., IEC 62304). Participate in architecture, risk assessment, and design reviews, especially in the context of regulated medical software. Support validation, verification, and regulatory submission processes by generating compliant documentation and test evidence. Diagnose and resolve issues related to BLE communication, device interoperability, and user-reported bugs. Documents software development and/or test development by writing documents, reports, memos, change requests. Methods used are determined by approved procedures and standards. Follow the full design life cycle process including driving efforts in requirements specification, design activities, planning, code reviews and creating corresponding artifacts. Analyzes, evaluates, verifies requirements, software and systems using software engineering standards and best practices Provide complete expert engineering solutions that are well thought out that is architecturally and technically sound Continuously improves process and work methodologies by interfacing with peers/cross-functional groups and analyzing activities to improve workflow and work processes. Promote a collaborative environment and pragmatic engineering decision-making. Develops and enhances cross-functional team relationships and works cross-functionally to identify and resolve technical and organizational issues. Build collaborative relationships with key leaders and peers, internally and externally, across the organization. 8+ years of experience in mobile application development, with at least 5+ years in Android (Kotlin/Java). Hands-on experience with BLE protocols for mobile-device interaction, ideally in healthcare or medical applications. Deep understanding of BLE operations: scanning, connecting, bonding, characteristic read/write, notifications, background tasks. Experience working in iOS development (Swift/Objective-C, Core Bluetooth). Preferred experience in HealthKit, Google Fit, or other health data APIs Familiarity with medical device software development lifecycle (IEC 62304), software documentation, and quality systems. Experience with Agile/Scrum methodologies and version control systems (Git). Strong analytical, debugging, and communication skills. Strong oral and written communication skills Ability to work independently and come up with solutions that are well thought out and technically sound Demonstrated experience in software development lifecycle (Agile), object-oriented design methodology Demonstrated technical leadership skills Creative / innovative thinker Good organizational and multi-tasking skills Bachelor's degree in computer science, electrical engineering, or a related field
