Senior RF Power Design Engineer

Nijmegen, Netherlands

Full Time

About the Role

The RF Power Design Engineer role consist of designing state of the art RF Transistors using Gallium Semi best in class GaN-SiC process. The engineer will be involved in product definition, device design, validation, design-in alongside with Application engineer and support ramp up to mass production. 

It is the Design engineer’s job to: 

  • Using CAD tool, Load-pull measurement and non-linear compact model, Design RF transistor with integrated pre-matching to meet specification. 

  • Evaluate and validate transistor design with Load-pull measurement and test demo board. 

  • Keep improving design performances thru innovation, improved Modelling technique or RF matching topology.

  • Collaborate across multiple engineering disciplines, including product, test, design, and marketing to support/ answer customers’ needs. 

  • Work closely with product marketing and Application to define future new RF products. 

  • Write technical documentation including application notes, white paper, etc. 

  • As a senior engineer, you will actively participate to the growth of the team, either as a team leader or a coach to junior engineers. 

  • Some travel will be necessary.


  • A university degree (MSc or PhD) in Electrical Engineering or equivalent with strong academic foundation on radio frequency principles.

  • 5+ years’ experience in RF design of GaN or LDMOS transistor.

  • Expert in RF laboratory equipment and measurement techniques including power amplifier circuit assembly and tuning.

  • VNA based Load-pull system and Non-Linear Modelling theory and usage is a premium.

  • Familiar with simulation tools such as Keysight ADS suite, HFSS, AutoCAD (or equivalent).

  • Excellent problem-solving skills with a proactive attitude.

  • Strong communication and interpersonal skills to interact with people at all levels including escalations and involvement of all group at stake.
