Job Description

[Recruitment Position] R&D Researcher for Rapid Freezer Control / MCU-Based Board Firmware Engineer We are an early-stage startup developing Peltier (TEC)-based refrigeration and cooling systems. We are implementing cooling systems centered on MCU-based control. We are seeking an engineer with board-based firmware design capabilities to participate in the initial product development process, which encompasses product planning, control architecture design, prototypes, and mass production. ※ Circuit/PCB design will be conducted through an internal/outsourced collaborative structure. This position will focus on understanding, reviewing, and collaborating on hardware, focusing on firmware design. [Responsibilities] ㆍMCU-based board firmware design and control logic development ㆍPeltier (TEC) element control method and IO board design ㆍTemperature sensor interface and control algorithm implementation ㆍC-based embedded firmware development and debugging ㆍElectronic circuit review and board BOM management ㆍCircuit diagram and PCB design review and collaboration ㆍPrototype testing and performance verification (using measurement equipment)

Qualifications

Education: Bachelor's degree or higher (electrical/electronic engineering/computer engineering, etc.) Experience: 2-7 years Experience developing firmware for MCU-based boards Experience developing and debugging C-based embedded systems Experience interfacing between MCU parts Experience configuring pin maps and firmware using circuit diagrams

Preferred

ㆍRelated certifications ㆍRelated major ㆍExperience with power/thermal control, such as Peltier (TEC), heaters, and motors ㆍUnderstanding of RTOS (FreeRTOS, etc.) usage or structure ㆍExperience with wired communications, such as RS-485 and CAN ㆍExperience writing mass production and test code ㆍExperience with small LCD or touch display integration (excluding UI design) ㆍExperience implementing data logging or system status monitoring ㆍExperience using at least one of the following programs/tools: - Circuit/PCB: Altium Designer, OrCAD, KiCad - MCU Development: STM32, Keil, IAR

Etc

We are looking for someone who: ㆍCan collaborate with hardware and solve problems, focusing on firmware. ㆍExperience developing control structures that consider current, heat, and power issues. ㆍExperience developing architectures in the early stages when specifications are not yet complete. ㆍExperience not only "making a product work," but also "stabilizing" it. Core Competencies ㆍPlanning, diligence, meticulousness, growth-oriented, achievement-oriented, creativity, teamwork Notes ㆍCurrently, we are focusing on MCU-based control development, and we are considering expanding communication, data, and AI-based functions in the future. ㆍExperience with RTOS, communications, UI, and data is not required, but is preferred. Summary - We are seeking a hands-on embedded firmware engineer capable of leading the design of MCU-based board firmware and implementation of control logic for a Peltier-based refrigeration system.
