Senior Microwave Engineer

Type: W2/C2C

We are an advanced climate technology company developing innovative industrial systems focused on carbon capture and sustainable process engineering. We are seeking a Senior Microwave Engineer to support the development of next‑generation high‑power microwave technologies in a hands‑on R&D environment.

This role is onsite in Berkeley, CA.

• Design and develop high‑power microwave heating systems (1 kW–100 kW, 900 MHz–3000 MHz)
• Perform RF/microwave simulation, modeling, testing, and experimental validation
• Optimize cavity, chamber, and waveguide designs using tools such as COMSOL or HFSS
• Build prototypes, execute test plans, analyze data, and drive iterative improvements
• Ensure microwave and high‑voltage safety compliance
• Collaborate with multidisciplinary engineering and R&D teams

• Bachelor’s degree in Electrical Engineering, Physics, Mechanical Engineering, or related field
• 5+ years of RF/microwave engineering or advanced R&D experience
• Strong knowledge of s‑parameters, impedance matching, wave propagation, chamber modeling, and material permittivity
• Experience with high‑power RF/microwave systems and electromagnetic simulation tools (COMSOL preferred)
• Hands‑on experimental and prototype development experience
• Knowledge of RF leakage detection, arc prevention, and high‑voltage safety
• Strong problem‑solving, communication, and cross‑functional collaboration skills
