Job description

Embedded C / Wireless Firmware Developer , Experience: 23 Years Location : Pune

Job Summary

We are seeking a hands-on Embedded C / Wireless Firmware Developer with 2 to 3 years of experience who bridges the gap between hardware and software. In this role, you will be responsible for bringing up microcontrollers, writing clean, low-level Embedded C code, and developing wireless communication pipelines . The ideal candidate has direct experience with STM32 and ESP32 architectures and understands how to read schematics to debug code directly on physical hardware.

Key Responsibilities

• Firmware Development: Design and write production-grade firmware in Embedded C for resource-constrained microcontrollers.
• Wireless Integration: Implement, configure, and optimize Bluetooth Low Energy (BLE) stacks, profiles, and services for data transmission and peripheral control.
• Hardware Bring-Up Diagnostics: Read hardware schematics to validate pins, bring up new prototypes, and troubleshoot physical boards.
• Platform Specialization: Develop firmware using STM32 (HAL/LL or bare-metal) and ESP32 (ESP-IDF) ecosystems.
• Peripheral Interfacing: Write and configure drivers for low-level protocols including SPI, I2C, UART, and GPIOs.
• Lab Debugging: Use test equipment such as logic analyzers, oscilloscopes, and JTAG/SWD debuggers to isolate firmware bugs from hardware faults.

Required Technical Skills

• Education: Bachelors degree in Electrical Engineering, Electronics Communication (ECE), Computer Engineering, or a related field.
• Experience: 2 to 3 years of professional experience in embedded systems development.
• Language Proficiency: Expert knowledge of Embedded C (memory management, pointers, registers, and interrupt handling).
• Hardware Architectures: Direct, hands-on experience with STM32 (ARM Cortex-M) and ESP32 (Xtensa/RISC-V) microcontrollers.
• Wireless Protocols: Practical exposure to BLE concepts (GAP, GATT, Advertising, Services, and Characteristics).
• Hardware Literacy: Ability to interpret electronic circuit schematics and datasheets.
• Development Tools: Familiarity with Git, STM32CubeIDE, VS Code (PlatformIO / ESP-IDF extension), and GCC toolchains.

Nice‑to‑Have Skills

• Experience with low-power optimization techniques for battery-operated BLE devices.

To finalize this draft, let me know:

• What product or application are they building (e.g., smart wearables, industrial sensors, medical devices)
