Firmware Engineer

Firmware Engineer – Embedded Systems

Role Overview

The Firmware Engineer will design, develop, and test embedded firmware that enables hardware systems to meet customer and product requirements. This role is hands‑on and non‑managerial, working closely with Electrical, Firmware, and Software Engineers to deliver production‑quality, real‑time, and fail‑safe firmware.

Required Skills & Experience

Core Technical Requirements

• 6–8 years of hands‑on embedded firmware development in C/C (not managerial)
• Proven experience writing firmware for embedded target devices
• Strong experience developing low‑level drivers and platform code
• Example: writing hardware drivers in C for RTOS platforms (e.g., Zephyr)
• Deep understanding of embedded systems and firmware architecture

Embedded Systems & RTOS

• Experience working with RTOS and real‑time embedded systems
• Knowledge of interrupts, boot mechanisms, and low‑level system behavior
• Experience with distributed or device‑level embedded systems

Hardware Interfaces & Peripherals

Hands‑on experience with multiple hardware interfaces, including:

• USB
• SPI
• I2C
• MIPI CSI / DSI
• UART
• GPIO

Must understand:

• Differences between common interfaces (e.g., SPI vs I2C)
• How to configure and debug peripheral drivers at the firmware level

Microcontrollers & Architectures

• Experience with embedded microcontrollers such as:
• ARM Cortex M0 / M3 / M4
• Understanding of:
• Bootloaders
• Interrupt priorities
• Peripheral configuration

Job Responsibilities

• Architect, design, implement, and test embedded firmware solutions
• Translate high‑level customer requirements into executable firmware tasks
• Develop and maintain unit tests to ensure firmware quality and reliability
• Troubleshoot firmware and system‑level issues and implement fixes
• Collaborate cross‑functionally with:
• Electrical Engineers
• Firmware Engineers
• Software Engineers
• Contribute to production‑quality, fail‑safe, low‑power real‑time systems

Additional Technical Skills

• Strong knowledge of the full software development lifecycleRequirements gathering
• Design and implementation
• Testing and delivery
• Experience with wired and wireless communication protocols, including:
• USB
• TCP/IP
• Ethernet
• Bluetooth
• 802.11
• Ability to debug and resolve complex hardware/firmware interactions

Nice‑to‑Have Skills

• Strong collaboration and teamwork skills
• Ability to work independently and manage time effectively
• Comfortable breaking down ambiguous or high‑level requirements into tasks
• Mentoring or peer‑support experience
• Clear verbal and written communication skills
