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

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.
