Role Summary We are seeking a skilled Embedded Firmware Developer with strong hands-on experience in 32-bit microcontroller-based systems. The ideal candidate brings deep expertise in low-level firmware development, peripheral interfacing, real-time system design, and hardware-level debugging. Experience in aerospace, defence, avionics, or other mission-critical electronics domains will be highly valued. Role Overview Department: Engineering / Embedded Systems / Avionics & Defence Electronics Employment

Type: Full-time, Permanent

Experience: 4 - 7 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

Key Responsibilities

• Develop, test, debug, and maintain embedded firmware for 32-bit microcontrollers and processors.

• Implement firmware for interfaces including UART, SPI, I²C, CAN, Ethernet, USB, ADC, DAC, PWM, and GPIO.

• Develop low-level drivers, board support packages, bootloader modules, and application-level firmware. • Design and implement RTOS-based systems covering task scheduling, inter-task communication, timers, interrupts, mutexes, queues, and memory management.

• 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 firmware design documents, test procedures, debug reports, and release notes.

• Participate in code reviews, unit testing, integration testing, and firmware release management.

• Collaborate with hardware, FPGA, systems engineering, QA, and production teams.

Required Skills & Experience

Core Programming

• Strong proficiency in Embedded C, Python; VB.NET knowledge is an advantage.

• Solid understanding of MCU architecture: memory map, registers, interrupts, DMA, timers, clocks, watchdogs, low-power modes.

• Experience with both bare-metal and RTOS-based firmware development.

Supported MCU Platforms

• ARM Cortex-M series (STM32, NXP, Microchip SAM / PIC32)

• Renesas, Infineon, or other equivalent 32-bit MCU platforms

RTOS Concepts

• Task/thread creation, priorities, and scheduling • Semaphores, mutexes, queues, and mailboxes

• Software/hardware timers and ISR-to-task communication

• Stack and heap management; memory safety

Communication Protocols

• UART, SPI, I²C, CAN / CAN-FD

• 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, SVN, or equivalent.

• 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, control systems, sensor interfacing, or actuator control experience.

• Python, VB, or scripting skills for test automation and utility development.

• Exposure to static analysis tools, unit testing frameworks, and CI for embedded firmware.
