Firmware & App Development Intern

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)
