If you’re tired of incremental improvements and want to design for tomorrow’s speed, scale, and integration needs, this could be the step up you’ve been looking for.

This team is building cutting-edge travelling-wave modulators that underpin the future of data transmission, across telecom and next-gen AI infrastructure. They’re blending electronics and photonics in ways most labs only talk about. And they need an experienced RF Design Engineer to take the lead.

What you’ll be doing:

You’ll join a specialist photonics R&D team focused on silicon photonics innovation, with tasks including:

· Designing RF elements (travelling line, Baluns, biasing, terminations)

· Evaluating different material systems and optical effects (Pockels, plasma dispersion)

· Creating equalization techniques to enhance device bandwidth and manage dispersion

· Interfacing with driver, test, and processing teams to co-engineer complete solutions

· Driving the layout, testing, and validation of integrated photonic circuits

What you’ll need:

· PhD in Photonics, Electrical Engineering, Physics, or similar with 3+ years’ experience

(or MSc with 6+ years’ experience)

· Solid track record in modulator design (Silicon or III-V materials)

· Proficiency in RF simulation tools like CST, HFSS, ADS or COMSOL

· Experience characterizing high-speed RF components

· Knowledge of silicon photonics device design and fabrication

· Familiarity with layout tools (Luceda, Tanner, etc.)

· Python and Linux skills are a bonus

What’s in it for you:

· A high-impact R&D role in a growing, well-resourced team

· Autonomy and responsibility for shaping RF performance across projects

· A collaborative culture in an international team based in vibrant Gent
