Principal Design Engineer

ETL Systems is a leading provider of RF design and manufacturing for satellite communications.

We’re looking for a hands‑on Principal Design Engineer to help shape the next generation of High Power Amplifier (HPA) systems across a broad frequency range up to V‑band.

This is a high‑impact, specialist engineering role where you’ll take ownership of designs from early concept through to production, working across both solid‑state (SSPA) and travelling wave tube (TWTA) technologies.

You’ll be given the autonomy to innovate, experiment, and bring ideas to life, combining simulation, system design, and real‑world lab development to deliver cutting‑edge RF solutions.

• Design and develop high‑performance high‑power amplifiers and systems covering C to V‑band (and beyond), defining RF architectures and key subsystems
• Carry out hands‑on lab work including tuning, measurement, fault finding, and optimisation
• Collaborate closely with RF, systems, electronics, and manufacturing teams
• Improve and evolve existing product designs for performance, efficiency, and reliability
• Support system integration, including power electronics and control interfaces
• Contribute technical insight to customer solutions and new opportunities
• Document designs and support knowledge sharing across the engineering community

• Experience with HPA systems, SSPA, TWTA, or similar technologies
• Knowledge of satcom or high‑frequency communication systems
• Exposure to millimetre‑wave or V‑band development (and beyond)
• Hands‑on prototyping or lab‑based development
