Senior Mobile Software Engineer (iOS & Android)

Location: Philadelphia/Remote

Employment Type: Full-Time

Will Report To: Software CTO (Chief Technical Officer)

Cogwear is seeking a Senior Mobile Software Engineer to lead the development and maintenance of our high-precision physiological monitoring platform. You will be responsible for a sophisticated Kotlin-based Android application that interfaces with clinical-grade EEG headbands via Bluetooth Low Energy (BLE) and USB Serial. A critical component of this role includes porting existing Android functionality to a new iOS application and expanding our AWS cloud integration to support large-scale telemetry pipelines.

Key Responsibilities

  • Real-Time Data Acquisition: Maintain and optimize the acquisition of raw EEG and IMU data at a precise time-stamping and synchronization.

  • Hardware Connectivity: Develop robust communication protocols for BLE (GATT) and USB Serial devices, including automatic reconnection handling and background data collection.

  • Security & Compliance: Implement medical-grade security controls, including AES-256 data-at-rest encryption via Android Keystore/iOS Secure Enclave, secure session management, and HIPAA-compliant audit logging.

  • Cloud Integration: Expand our cloud-native deployment using AWS Amplify, specifically utilizing Cognito for authentication and S3 for raw data storage.

  • Signal Processing & Visualization: Implement digital signal processing (DSP) filters (Bandpass, Notch) using custom and standard libraries and visualize real-time waveforms using MPAndroidChart.

  • Data Integrity: Design "offline-first" recovery systems, including local data queueing and partial upload recovery to prevent data loss during connectivity drops.

  • Regulatory Documentation:Collaborate on FDA-ready build artifacts and integrate requirements tracking between Jira and Quality Management Systems.

Why Join Us

  • Help shape a cutting-edge technology with applications in healthcare, consumer insights, and athletics.

  • Flexible part-time schedule with meaningful impact.

  • Collaborative, mission-driven environment where your contributions matter.

Required Qualifications

  • Android: Deep proficiency in Kotlin, Coroutines, and UI development with Jetpack Compose.

  • iOS (Upcoming): Ability to translate Kotlin architectures into Swift/SwiftUI for a parallel iOS deployment.

  • Backend/Cloud: Hands-on experience with AWS (Cognito, S3) and Socket.io for real-time data streaming.

  • Connectivity: Expert knowledge of the Android Bluetooth/BLE stack and USB Host API.

  • Networking: Experience with Retrofit2, OkHttp3, and RESTful API integration.

  • Tools: Mastery of Git, Jira, and Firebase Crashlytics for real-time diagnostics.

Preferred Qualifications

  • Experience developing Software as a Medical Device (SaMD) under ISO 13485 or FDA 21 CFR Part 11.

  • Familiarity with digital signal processing (DSP), Fast Fourier Transforms (FFT), and filtering artifacts.

  • Background in large-scale telemetry, crash reporting optimization, and performance profiling for long-running (10+ minute) data streams.
