Job Description

Senior RF Systems Engineer 

Are you passionate about high-power RF systems and solving complex engineering challenges?

We are looking for an experienced RF Systems Engineer to design and optimise induction-heating technology used in advanced crystal-growth processes. You will combine RF design, simulation and hands-on experimentation to improve systems operating in demanding high-temperature environments.

What You’ll Do

• Design and optimise high-power induction-heating systems, typically operating at 1–50 kHz.
• Develop and tune resonant circuits, matching networks, capacitor banks and RF generators.
• Design induction coils for improved heating profiles, coupling efficiency and stability.
• Support crystal-growth platforms such as CZ, HEM, skull melting and Bridgman.
• Model electromagnetic and thermal performance using COMSOL, ANSYS Maxwell or similar tools.
• Troubleshoot detuning, reflected power, instability, resonance shifts and coil overheating.
• Design and review cooling systems, bus bars and high-current electrical connections.
• Lead testing, validation and commissioning of new equipment and upgrades.
• Work with materials scientists and engineering teams to move technology from R&D into production.
• Share your expertise and support the development of junior engineers.

What You’ll Bring

• A bachelor’s or master’s degree in Electrical Engineering, Physics or a related field.
• At least five years’ experience in RF power, induction heating or high-power electronics.
• Strong knowledge of resonant circuits, impedance matching and RF power delivery.
• Practical experience working with induction-heating systems.
• Experience with high-temperature, vacuum or controlled-atmosphere equipment.
• A curious, hands-on approach to testing, troubleshooting and problem-solving.
   

Experience with crystal growth, advanced materials, thermal-management design or RF generators would be a great advantage.

Why Coherent?

At Coherent, you will work on technology where electrical engineering, advanced materials and real-world manufacturing come together. You will have the opportunity to experiment, solve meaningful technical problems and help shape the next generation of crystal-growth systems.
