Role Summary

As an Embedded Systems Engineer, you will be instrumental in designing, building, and testing embedded hardware and firmware. This includes developing custom PCBs, low-power sensor nodes, and device firmware using C/C++. You will also implement connectivity solutions such as BLE and Wi-Fi. This role offers end-to-end ownership of prototypes, from schematic design and layout to bring-up and validation, in close collaboration with mechanical, QA/RA, and product teams.

Key Responsibilities

• Electronics Design: Capture schematics, perform component sizing, and lay out 2–6 layer PCBs, applying principles of high-speed and mixed-signal design, power domains, grounding, and EMI/ESD best practices.
• Firmware Development: Write and debug C/C++ code for microcontrollers (e.g., STM32, ESP32, nRF52), develop drivers for sensors and actuators, implement FreeRTOS tasks, manage power consumption, and create basic bootloaders and Over-The-Air (OTA) update mechanisms.
• Connectivity/IoT: Integrate BLE GATT, Wi-Fi with MQTT/HTTP, implement basic security features (TLS, key management), and design data protocols for device-to-app and device-to-cloud communication.
• Bring-up & Testing: Utilize lab equipment such as oscilloscopes, logic analyzers, DMMs, and power analyzers for board verification. Write test firmware and prepare validation reports.
• Prototyping: Perform component rework and soldering (0402/SOIC/QFN), assemble lab prototypes, wire test fixtures, and provide Design for Manufacturing (DFM) and Design for Testability (DFT) feedback to vendors.
• Documentation: Create and maintain Bills of Materials (BOMs), revision notes, test plans, and risk logs. Utilize issue tracking systems like Git and Jira.
• Quality & Safety: Adhere to basic IEC 60601 and EMC guidelines in design. Support the generation of verification records for ISO 13485 compliance (training will be provided).
• Collaboration: Work closely with application and cloud development teams on API integration and with mechanical engineers on enclosure design, thermal management, and connector selection.

Qualifications

• 1–3 years of hands-on PCB design experience using KiCad or Altium, with at least one end-to-end designed and tested board.
• Proficiency in C/C++ for microcontrollers, with experience in STM32/ESP32 or similar platforms and familiarity with FreeRTOS.
• Comfort and experience using lab equipment (oscilloscope, logic analyzer) for debugging firmware and hardware interactions.
• Solid understanding of basic analog circuit principles, including op-amp interfaces, sensor signal conditioning, ADC/DAC usage, filters, and buck/linear regulators.
• Exposure to BLE/Wi-Fi stacks and common serial communication protocols (I²C, SPI, UART, CAN).
• Strong documentation skills and experience with version control systems like Git.

Benefits

• Competitive salary package.
• Opportunities for professional growth and career advancement.
• A dynamic and collaborative work environment.
• Cell phone reimbursement.
• Health insurance.
• Provident Fund.
