Principal Digital Design Engineer
Architect and deliver the configurable IO subsystem for onsemi's microcontroller platform.
About the role
This Principal Digital Design Engineer owns the IO subsystem for onsemi's microcontroller platform in Allen, TX. The role is responsible for defining, architecting, and delivering a configurable IO subsystem optimized for performance, power, and area across multiple end markets.
What you'll do
- Own the architecture, specification, interfaces, and RTL implementation of the configurable IO subsystem.
- Define and implement parameterized, Python generator-based design approaches enabling scalable subsystem instantiation.
- Develop SystemVerilog RTL compatible with automated generation flows and maintainable at scale.
- Drive the creation of automatically generated testbenches and verification environments leveraging UVM frameworks.
- Support synthesis, STA, and timing closure activities to deliver signoff-ready designs.
- Apply AI/ML techniques to support code generation, verification acceleration, and design space exploration.
What you'll need
- Bachelor’s degree in Electrical Engineering or a related field.
- 10+ years of experience in digital IC design with a strong RTL development background.
- Expert-level proficiency in SystemVerilog RTL design.
- Strong experience with Python for design automation and tool development.
- Solid experience with UVM-based verification methodologies and testbench development.
- Strong understanding of UPF, synthesis, STA, and timing signoff flows, along with DFT concepts and integration.
Nice to have
- Master’s degree in Electrical Engineering or related field.
