About the Role
We are looking for a motivated and detail-oriented Junior Embedded Engineer to join our engineering team. This role is suitable for a candidate who wants to build a strong career in embedded systems and medical device development. The selected candidate will work closely with senior engineers on firmware development, hardware bring-up, debugging, testing, and product improvement activities.
The role requires a good understanding of embedded programming, microcontrollers, and basic electronics. The candidate should be comfortable learning quickly, supporting ongoing projects, and contributing to product development in a hands-on environment.
Key ResponsibilitiesEmbedded Programming and Firmware Support
- Support development, testing, and debugging of embedded firmware for medical devices.
- Work on microcontroller-based systems such as STM32, ESP32, AVR, PIC, or similar platforms.
- Assist in writing firmware for peripheral interfaces and communication modules such as UART, SPI, I2C, ADC, PWM, GPIO, USB, BLE, and Wi-Fi, depending on product requirements.
- Support development and debugging of Bluetooth Low Energy (BLE) and Wi-Fi-enabled embedded features for connected medical devices.
- Assist in implementing and validating wireless communication workflows such as pairing, device discovery, secure data exchange, and connectivity stability.
- Help optimize embedded code for stability, performance, memory usage, and power efficiency.
- Support integration of firmware with sensors, communication modules, and hardware subsystems.
Wireless Connectivity Support
- Assist in bring-up and testing of BLE and Wi-Fi platforms used in medical devices.
- Support troubleshooting of wireless connectivity issues related to pairing, reconnection, packet loss, latency, and range.
- Work with senior engineers on integration of embedded devices with mobile apps, cloud platforms, or host systems through BLE or Wi-Fi.
- Help validate wireless communication performance under real-use scenarios.
Hardware and Board Bring-Up Support
- Assist in board bring-up and initial hardware validation of prototypes.
- Support debugging of issues related to power supply, communication, signal acquisition, and embedded control logic.
- Work with senior engineers to identify and resolve hardware-software integration issues.
- Perform basic testing using lab tools such as multimeters, oscilloscopes, logic analyzers, and signal generators.
Testing and Validation
- Execute firmware test cases and document observations.
- Support design verification and validation activities for embedded functions.
- Assist in troubleshooting failures seen during development, pilot build, or production stages.
- Participate in product reliability testing and issue tracking.
Documentation
- Prepare and maintain basic technical documentation such as:
- Firmware notes
- Interface descriptions
- Debug logs
- Test reports
- Version history
- Ensure proper documentation of code changes and firmware releases.
Cross-Functional Coordination
- Work with hardware, software, QA, and production teams during development and testing.
- Support implementation of engineering feedback from field, testing, or manufacturing teams.
- Participate in design discussions and review meetings as required.
Required Qualifications
- Bachelor’s degree in Electronics Engineering, Electrical Engineering, Embedded Systems, Instrumentation, Biomedical Engineering, or a related field.
- Basic understanding of embedded C/C++ programming.
- Familiarity with microcontrollers and embedded development environments.
- Understanding of digital electronics, basic analog electronics, and circuit interfacing.
- Basic knowledge of communication protocols such as UART, SPI, I2C, and exposure to BLE and Wi-Fi platforms.
- Good problem-solving ability and willingness to work in a hands-on development environment.
Preferred Skills
- Internship, academic project, or project-based experience in embedded systems or electronics development.
- Familiarity with tools such as Keil, STM32CubeIDE, Arduino IDE, PlatformIO, MPLAB, or equivalent.
- Basic exposure to BLE module integration, Wi-Fi-based device communication, and embedded connectivity debugging.
- Basic exposure to PCB-level debugging and hardware validation.
- Understanding of firmware version control practices.
- Interest in medical devices, biomedical instrumentation, or healthcare technology.
What We Offer
- Opportunity to work on real medical-device products with strong practical learning exposure.
- Hands-on experience in embedded systems, electronics, wireless communication, and regulated product development.
- A collaborative engineering environment with mentorship from experienced team members.
- Structured growth opportunities in firmware and hardware product development.
Ideal Candidate Profile
The ideal candidate is curious, disciplined, and eager to learn. They should be comfortable working closely with hardware and firmware, following engineering processes, and taking ownership of assigned technical tasks. A strong willingness to learn and contribute is more important than extensive prior experience for this role.
