Job Title

MCU System Architect (1)

Role Summary

Lead system-level architecture for next-generation microcontroller (MCU) products, defining CPU, memory, bus, peripheral, power, clock, security and safety features to meet market and customer requirements.

Work across hardware, firmware, and product-planning teams from product concept through mass production to optimize performance, power, area and cost for competitive MCU platforms.

Experience Level

Mid-level - typically requires around 5+ years of practical experience in semiconductor product development (MCU/SoC/ASIC).

Responsibilities

The role owns MCU system architecture and drives product definition and technical decisions across the development lifecycle.

  • Design system architecture for microcontroller products (CPU, memory, bus, peripherals, analog, security, communications).
  • Analyze market and customer requirements to define product specifications and system configuration for next-generation MCUs.
  • Propose hardware configurations that balance performance, power consumption, chip area and manufacturing cost.
  • Evaluate and define specifications for new peripherals and features.
  • Collaborate with semiconductor/hardware engineers, software/firmware engineers, and product planning to drive product development.
  • Lead technical reviews and make architecture-level decisions within development projects.
  • Contribute to MCU platform strategy and product roadmap planning.

Requirements

Required skills and experience are divided into must-have and nice-to-have items.

Must-have
  • Practical experience in semiconductor product development (MCU, SoC or ASIC), approximately 5+ years.
  • Experience in at least one of: digital circuit design, embedded software development, or system design.
  • Knowledge of embedded-system architecture including CPU, memory, bus and peripheral subsystems.
  • Experience writing product specifications and requirement documents.
  • Proven ability to lead and drive cross-functional product development projects.
Nice-to-have
  • Direct experience in MCU or SoC system/architecture design and product specification definition.
  • Familiarity with CPU architectures such as ARM or RISC-V.
  • Knowledge of low-power design techniques, functional safety and security features.
  • Experience with peripheral and interface technologies (CAN, Ethernet, USB, SPI, I2C, etc.).
  • Track record of system-level problem analysis and proposing architectural solutions.

Education Requirements

Not specified.
