Firmware & App Development Intern

2 weeks ago

Singapore Resmed Full time $40,000 - $80,000 per year
About The Role

Join our engineering team to build end-to-end prototypes that connect custom electronic modules to smartphones and PCs via wireless communications. You'll write embedded firmware for microcontrollers and develop companion mobile/desktop apps to configure, stream, and visualize data. This is a hands-on role spanning hardware bring-up, wireless communications design, algorithms, and user-facing software.

What You'll Do

  • Implement and test firmware in C/C++ for MCU-based wireless electronic modules

  • Design wireless communication (e.g. BLE services/characteristics (GATT), pairing/security, and data-streaming for reliable phone/PC connectivity)

  • Build companion mobile or desktop apps (Android/iOS or Windows/macOS) for device control, data logging, and OTA updates.

  • Interface with sensors and peripherals via UART/I²C/SPI

  • Prototype and evaluate algorithms (e.g., filtering, calibration, event detection) and profile performance on-device and in app.

  • Bring-up hardware: read schematics/datasheets, perform board-level testing and debugging.

  • Write unit and integration tests; assist with test automation and CI for firmware/app builds.

  • Document designs, APIs, and test results

Preferred Skills

  • Programming in C/C++ (firmware) and preferably one of: Kotlin/Java (Android), Swift (iOS), Dart/Flutter, React Native, C#/WPF, Python+Qt/Electron.

  • Knowledge of wireless communications fundamentals (e.g. Bluetooth Low Energy: advertising, connection parameters, GATT services/characteristics, throughput & latency trade-offs)

  • Familiarity with microcontrollers, interrupts/RTOS basics, and peripheral drivers.

  • Comfortable using Git and writing clear documentation.

  • Strong problem-solving, debugging, and hands-on lab skills.

  • Building cross-platform UIs; plotting live sensor data; basic REST/WebSocket integrations.

  • OTA firmware update pipelines, secure bootloaders, and basic cryptography for BLE.

  • Signal processing basics (filters, peak detection), numerical methods, or ML on embedded targets.

  • Experience with electronic hardware modifications, soldering and oscilloscope.

  • Exposure to hardware design/verification, DFM/DFT, and EMC considerations.

  • Awareness of development in regulated environments (e.g., medical, consumer health, IoT).

Tools & technologies you may use here
  • C/C++, Python; Android Studio, Xcode, Flutter or React Native; BLE analyzers (nRF Sniffer, Ellisys); JTAG/SWD; oscilloscopes/logic analyzers; UART/I²C/SPI; Git/GitHub; CI (GitHub Actions); issue tracking (Jira).

Suitable streams of study

  • Electronics & Communication Engineering (ECE)

  • Electrical & Electronics Engineering (EEE)

  • Computer Engineering / Computer Science (with embedded/IoT focus)

  • Instrumentation / Control Engineering

  • Mechatronics / Robotics

  • Biomedical Engineering (with embedded systems or signal processing electives)

  • Information Technology (with strong systems/embedded electives)

What You'll Learn

  • End-to-end product thinking from sensor to smartphone/cloud.

  • BLE performance tuning, low-power design, and robust over-the-air updates.

  • Practical debugging and validation on real hardware.

  • Collaborative engineering workflows (reviews, testing, CI/CD)
