Job description

Position Summary

We are seeking an experienced Embedded Software Engineer to design, develop, and support embedded firmware for industrial electronic products. This role will focus on low-level, bare-metal firmware development and full product lifecycle ownership, from concept and architecture through release and production support.

Responsibilities

• Develop embedded firmware in C for microcontroller-based systems.
• Lead products through the complete development lifecycle, from requirements and design through validation, release, and maintenance.
• Design and implement bare-metal embedded software solutions.
• Develop software for real-time operating systems (RTOS/FreeRTOS) environments.
• Interface embedded systems with communication protocols such as RS232, USB, Ethernet, and Wi-Fi.
• Collaborate with hardware, manufacturing, and test engineering teams to troubleshoot and optimize system performance.
• Support product verification, validation, and field issue resolution.

Required Qualifications

• Strong proficiency in C programming for embedded systems.
• Proven experience delivering multiple cradle-to-grave embedded products utilizing bare-metal programming.
• Experience developing software in a real-time operating system (RTOS) environment, such as FreeRTOS.
• Working knowledge of embedded communications including several of the following:
  • RS232
  • USB
  • Ethernet
  • Wi-Fi
• Strong debugging and troubleshooting skills at the hardware/software interface.

Preferred Qualifications

• Experience with Embedded Linux development.
• Knowledge of SDIO interfaces.
• Experience with RS485 communication protocols.
• Familiarity with industrial control, automation, or connected device applications.
• Exposure to C++ is acceptable; however, the primary development language is C.

Ideal Candidate

The ideal candidate is a hands-on embedded engineer who has successfully brought products from concept through production and is comfortable working close to the hardware in resource-constrained, real-time environments. They enjoy solving complex technical problems and thrive in a collaborative engineering culture.
