About the Role

We are seeking a skilled Low-Level / Platform Firmware Engineer with solid hands-on experience in 32-bit microcontroller-based systems. The ideal candidate brings deep expertise in driver development, peripheral interfacing, board bring-up, and hardware-level debugging — building the foundation that every layer of application firmware runs on. Experience in aerospace, defence, avionics, or other mission-critical electronics domains will be highly valued. Role Overview

- Department Engineering / Embedded Systems / Avionics & Defence Electronics
- Experience 2 - 5 Years of relevant embedded firmware experience
- Qualification B.E. / B.Tech / M.E. / M.Tech — Electronics, Electrical, Embedded Systems, Instrumentation, Computer Science or related discipline
- Domain Preference Aerospace, Defence, Avionics, Space, or Mission-Critical Systems

Responsibilities

- Develop, test, debug, and maintain embedded firmware for 32-bit microcontrollers and processors.
- Implement drivers for peripherals including UART, SPI, I²C, CAN, Ethernet, USB, ADC, DAC, PWM, and GPIO.
- Develop low-level drivers, board support packages (BSPs), and bootloader modules.
- Perform MCU initialization: startup code, linker scripts, clock trees, MPU/cache configuration, and interrupt priority assignment.
- Perform board bring-up, hardware validation, firmware integration, and system-level debugging.




- Use lab instruments — DSO, logic analyzer, protocol analyzer, multimeter, function generator, JTAG/SWD debuggers — to characterize and debug issues.
- Diagnose communication failures, timing problems, interrupt latency, noise, grounding issues, and signal integrity faults.
- Review schematics and hardware designs from a firmware integration perspective.
- Support design verification, environmental testing, and EMI/EMC qualification activities.
- Prepare driver-level design documents, bring-up reports, debug reports, and release notes.
- Participate in code reviews and unit testing of drivers and low-level modules.
- Collaborate with the Application Firmware Engineer, hardware, FPGA, and QA teams.

Qualifications

- B.E. / B.Tech / M.E. / M.Tech — Electronics, Electrical, Embedded Systems, Instrumentation, Computer Science or related discipline

Required Skills Required Skills & Experience

- Core Programming, Strong proficiency in Embedded C; working knowledge of Python for scripting.
- Solid understanding of MCU architecture: memory map, registers, interrupts, DMA, timers, clocks, watchdogs, low-power modes.
- Primary experience in bare-metal firmware development, with the ability to bring drivers up under an RTOS.

Supported MCU Platforms
- ARM Cortex-M series (STM32, NXP, Microchip SAM / PIC32)
- Renesas, Infineon, or other equivalent 32-bit MCU platforms

RTOS Concepts
- ISR-to-task handoff and interrupt priority assignment at the driver boundary
- Hardware timer configuration for OS tick and peripheral timing
- Enough working knowledge of task/thread context to hand off a clean, RTOS-safe driver interface to the application layer

Communication Protocols




- UART, SPI, I²C, CAN / CAN-FD — register-level configuration and driver implementation
- RS-232, RS-485, Ethernet, USB

Debugging & Tooling
- JTAG, SWD, breakpoints, watchpoints, memory views, register inspection, trace tools.
- Proficient with lab instruments: DSO, logic analyzer, protocol analyzer, multimeter, function generator.
- Working knowledge of IDEs/toolchains: Keil, IAR, STM32CubeIDE, MPLAB X, Code Composer Studio, GCC, Eclipse.
- Source control: Git.
- Ability to independently read schematics and component datasheets.

Preferred Skills

- Prior experience in aerospace, defense, avionics, space, radar, electronic warfare, or mission-critical embedded systems.
- Familiarity with MISRA C, MIL-STD requirements, or RTCA qualification processes.
- Experience with secure boot, firmware upgrade mechanisms, CRC verification, watchdog strategy, and fail safe design.
- Knowledge of high-reliability and fault-tolerant embedded design practices.
- EMI/EMC debugging experience and environmental testing support.
- FPGA interface bring-up and processor-FPGA communication design.
- Real-time data acquisition, sensor interfacing, or actuator control experience at the driver level.
- Python or scripting skills for test automation and utility development.
- Exposure to static analysis tools for embedded firmware.
- Programming: Embedded C (primary), C++ (preferred), Python scripting
- RTOS: FreeRTOS.
- Debug Tools: JTAG, SWD, ST-Link, J-Link, Lauterbach, XDS, or equivalent
- Lab Instruments: DSO, Logic Analyzer, Protocol Analyzer, Multimeter, Function Generator
- Protocols: UART, SPI, I²C, CAN / CAN-FD, Ethernet, USB, RS-232, RS-485
