Job Requirements

Senior Firmware Engineer – Embedded Microcontroller Development

Role Overview

We are seeking an experienced Senior Firmware Engineer to lead the design and development of embedded firmware for microcontroller-based systems. The role focuses on architecting reliable, scalable, and high‑performance firmware for platforms such as STM32 , TI C2000 , and TI multicore MCUs. The candidate should have strong embedded C/C++ expertise, RTOS experience, and hands‑on hardware–software integration skills.

Experience with MQTT protocols, IoT frameworks, or connected device architectures is a strong plus.

Key Responsibilities

Firmware Architecture & Development

Design, develop, and maintain embedded firmware for ARM Cortex‑M and TI MCU platforms.
Develop and optimize peripheral drivers, middleware, communication stacks, and board support packages (BSP).
Implement modules involving ADC/DAC, PWM, DMA, timers, watchdogs, interrupts, and low‑power modes.
Architect RTOS‑based systems using FreeRTOS or similar operating systems.

Hardware–Software Integration

Collaborate with hardware teams for board bring-up, schematic validation, and design reviews.
Debug hardware/firmware integration issues using oscilloscopes, logic analyzers, and JTAG/SWD.
Validate and tune interfaces such as:
SPI, I²C, UART, CAN, LIN
Modbus/RS485, Ethernet, Profinet
USB or proprietary protocols

System Optimization & Reliability

Optimize real‑time performance, memory usage, and power consumption.
Implement robust error-handling, diagnostics, and state-machine-driven architectures.
Perform code reviews, static analysis, unit testing, and regression testing.

Documentation & Quality

Prepare architectural documents, design specifications, interface definitions, and API documentation.
Ensure firmware quality through coding standards (MISRA‑C or equivalent).
Support validation engineers and ATE teams with firmware-level hooks and testability features.

Cross-Functional Collaboration

Work closely with system, hardware, ATE, and validation teams.
Provide mentorship and technical leadership to junior firmware engineers.
Participate in system-level architecture decisions including communication frameworks, bootloaders, and security features.

Work Experience

Technical Skills

Bachelor’s/Master’s degree in Electronics, Electrical, Computer, or Embedded Systems Engineering.
7+ years of proven experience in embedded firmware development.
Hands-on experience with:
STM32 (ARM Cortex‑M series)
TI C2000 / TI multicore DSP/MCU platforms (preferred)
Strong expertise in:
Embedded C/C++
RTOS (FreeRTOS, TI‑RTOS, ThreadX, etc.)
Interrupt-driven programming and real-time firmware
Familiarity with:
JTAG/SWD tools, oscilloscopes, logic analyzers
Memory interfaces: Flash, EEPROM, FRAM
Common industrial protocols

Good To Have (Preferred)

Experience with MQTT protocol for messaging or telemetry.
Exposure to IoT architectures, device connectivity, or cloud‑connected embedded systems.
Experience building connected dashboards or interacting with IoT gateways.
Background in ATE/HIL environments or automation frameworks.
Knowledge of security best practices, OTA updates, and remote diagnostics.
Experience with Git, CI/CD for firmware, static analysis tools, or DevOps for embedded.
