Let us tell you a little bit about Sparc
Sparc Foundry develops and produces photonic semiconductors as part of a strong European photonics ecosystem.
The foundry will produce PICs (Photonic Integrated Circuits) and discrete components based on Group III-V semiconductors It will have the capacity to develop 20,000 wafers per year with different types of technologies based on Group III-V materials, including GaAs (Gallium Arsenide), InP (Indium Phosphide), and GaN (Gallium Nitride). These components will be used by industries around the world in sectors such as automotive, telecommunications, quantum computing, consumer electronics, defense, aerospace and medicine.
⭐ What will you do with us?

The Senior RF Engineer will play a pivotal role in our III-V semiconductor foundry team, leading the development, characterization, and model verification of next-generation ultra high-power RF components. This role bridges the gap between semiconductor device physics and circuit design. The successful candidate will drive the design and evaluation of GaN-based Power Amplifiers (PAs)



exceeding 500W, establishing rigorous small and large signal characterization methodologies to validate advanced compact models and support foundry process optimization.
Job Functions
- Ultra High-Power GaN PA Design: Lead the design, simulation, and layout of ultra high-power RF amplifiers utilizing GaN (Gallium Nitride) technology for power levels exceeding 500W.
- Simulation & Circuit Analysis: Utilize Keysight Advanced Design System (ADS) to perform advanced RF/microwave circuit simulations, electromagnetic (EM) co-simulation, and large-signal harmonic balance analysis.
- Small & Large Signal Testing: Define, develop, and execute comprehensive RF characterization techniques (small-signal S-parameters and large-signal/pulsed parameters) for active high-power devices.
- Model Verification & Physics Alignment: Validate and verify active and passive device compact models against laboratory data, en
