Prototyping Engineer

Experience: 3 - 5 yrs

Work Location: Bangalore

We are seeking a Smart Modules Prototyping Engineer to lead the design, integration, and validation of embedded smart modules for next generation connected products. You will work closely with cross-functional teams to rapidly prototype, evaluate, and iterate on hardware designs involving cellular modems (e.g., LTE/5G), Wi-Fi, GNSS, Bluetooth, eSIM, and sensors across automotive and industrial IoT platforms.

Areas Of Responsibility

• Hardware Integration & Prototyping

Rapid prototyping of smart modules using reference designs, EVKs, or custom carrier boards.

Integration of communication modules - Qualcomm-based SOMs

Work with eSIMs/eUICCs including solderable (MFF2) and pluggable variants.

• Firmware & Software Bring-up

Assist in booting Android/Linux on target platforms (e.g., QCM2290, QCX216, i.MX, STM32).

Collaborate with BSP and HAL teams to verify drivers for key peripherals.

Work with FreeRTOS, Linux, and Android to validate core functionality (GNSS, LTE/5G, Wi-Fi, audio, GPIO).

• Validation & Testing

Perform functional testing of hardware modules using lab equipment (oscilloscopes, logic analyzers, signal generators).

Validate modem and RF performance including TRP/TIS, SAR pre-checks.

Test peripherals: camera interfaces (MIPI CSI), display (MIPI DSI), sensors (I2C/SPI), etc.

• Schematic Review & Hardware Debug

Participate in design reviews and suggest improvements for DFM, power integrity, RF layout.

Debug hardware issues during bring-up using JTAG, UART logs, and RF diagnostic tools.

• Cross-Team Collaboration

Interface with product management, software, and hardware design teams to align prototype goals.

Documentation:

• Technical Documentation: Create detailed documentation for BSP and board bring up processes, including user manuals and technical guides.
• Reporting: Maintain logs and reports of testing and debugging activities

Experience and Qualification

Experience:

• Strong knowledge of embedded hardware systems and SoC-based design.
• Experience with one or more smart module vendors (
• Proficiency in using lab tools (oscilloscope, multimeter, logic analyzer).
• Working experience with Android/Linux/RTOS bring-up on ARM-based platforms.
• Knowledge of cellular communication (4G, 5G, NB-IoT), GNSS, Bluetooth, and Wi-Fi.
• Experience in handling eSIM stack integrations.

Qualifications:

• Bachelor’s or master’s degree in Electronics/Electrical Engineering, or a related field.
• Strong knowledge of Linux kernel architecture and driver development.
• Familiarity with hardware interfaces and protocols such as I2C, SPI, UART, USB, and Wifi/Modem/Bluetooth.
• Experience with debugging tools and techniques for hardware and software issues.
• Knowledge of open-source development practices and tools.

Technical And Behavioural Skills

Technical Skills:

• Experience with Linux kernel development and customization.
• Knowledge of hardware abstraction layers and low-level programming.
• Experience with Android HAL, LPA, and RIL layers.
• Familiarity with soldering and rework of BGA/LGA packages.
• Understanding of RF and antenna tuning basics.
• Basic scripting (Python, Bash) for automation and test scripts.
• Familiarity with regulatory and carrier certification processes.

Behavioural Skills:

• Strong communication and teamwork skills.
• Ability to adapt to a fast-paced and dynamic business environment.
• Detail-oriented with a focus on quality and accuracy.
• Proactive and self-motivated with a results-oriented mindset.
