Embedded C / Wireless Firmware Developer

• *Experience: 2–3 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: Bachelor’s 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)
