Job Title

MCU System Architect (2)

Role Summary

Design and define system-level architecture for next-generation microcontroller (MCU) products, including CPU, memory, bus, peripherals, power/clock and security features. Lead cross-functional coordination from product concept through to mass production with hardware, software and product planning teams.

This role drives technical trade-offs to optimize performance, power, cost and manufacturability for embedded markets (industrial, consumer, automotive).

Experience Level

Mid-level - typically requires around 5+ years of practical experience in semiconductor product development.

Responsibilities

Key responsibilities include:

  • Define MCU product specifications and overall system configuration based on market and customer requirements.
  • Architect CPU, memory, buses, analog and communication peripherals, security and power/clock systems for MCUs.
  • Perform trade-off analyses considering performance, power consumption, die area and manufacturing cost.
  • Evaluate and specify new peripheral features and system-level functionality.
  • Collaborate with semiconductor design engineers, embedded software teams and product planners to drive development.
  • Conduct technical reviews and make architecture-level decisions during development projects.
  • Contribute to future MCU platform and product roadmap planning.

Requirements

Essential and desirable qualifications for the role.

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 covering CPU, memory, bus and peripheral integration.
  • Experience preparing product specifications and requirements documents.
  • Track record of driving cross-functional product development projects.

Nice-to-have:

  • Direct MCU or SoC system/architecture design experience and product specification work.
  • Familiarity with CPU architectures such as ARM or RISC-V.
  • Knowledge of low-power design, functional safety and security features.
  • Experience with common interfaces: CAN, Ethernet, USB, SPI, I2C, etc.
  • Ability to analyze technical issues at the system level and propose solutions.

Education Requirements

Not specified.
