RF Design Engineer Trainee (Microwave Technology)
We are not hiring summer help - we are looking for a future RF engineer who wants to continue with a diploma thesis and grow into a permanent role.
Sensofusion is looking for an ambitious and hands-on RF design engineer trainee to join our hardware team.
This is not a theoretical role. We are looking for someone who enjoys real RF hardware, understands electromagnetic fields beyond textbooks, and wants to design high-performance
RF systems.
What you’ll do - Design and simulate RF circuits and subsystems, including:
● High Power Amplifier Design
● RF filter design
● Mixer design
● RF circuit and layout design
● EM simulation and optimization
● Lab measurements and correlation between simulations and hardware
You will design, simulate, build, measure, debug - and improve.
You will work closely with experienced RF engineers and take real responsibility from day one.
What we expect from you
● Final-stage MSc student or recent graduate in:
● Microwave Engineering
● RF Engineering
● Or related field such as Electrical Engineering or Space Technology, as long as
there is a strong RF focus
● Strong hands-on interest in RF hardware.
● Experience with AWR / ADS
● Solid understanding of S-parameters, impedance matching, stability, gain, noise, and
signal chain analysis
● Familiarity with RF simulation workflows
● Familiarity with lab equipment (VNA, spectrum analyzer, signal generator, oscilloscopes
etc)
● Experience with KiCAD or similar and Git
Understanding of nonlinear RF behavior and power amplifiers is considered a big plus.
You enjoy solving real technical problems and take ownership of your work.
You are willing to work from our headquarters in the Helsinki capital region. Remote work is not
possible.
Practical experience of RF technology and engineering projects is appreciated.
As part of your application -
Include a short description of an RF system or subsystem you have designed:
● Design goals and frequency range
● Tools used
● Key technical challenges
● Simulation vs. measurement comparison (if available)
● Your exact role in the project
We are interested in how you think and solve problems
