hirify.global designs, builds, and services materials engineering equipment used to manufacture semiconductor chips and advanced displays.

What you will do

• Lead the architecture, specification, development, integration, and qualification of RF power delivery systems, including generators, match networks, sensors, diagnostics, transmission lines, grounding, and shielding.
• Translate process, system, and customer requirements into RF subsystem designs that improve plasma performance, uniformity, stability, repeatability, efficiency, reliability, manufacturability, and cost competitiveness.
• Serve as the RF technical lead for advanced development programs and integrate RF subsystems with chamber hardware, ESCs, gas delivery, controls, and software.
• Analyze plasma ignition, RF coupling, harmonic behavior, defectivity, wafer-to-wafer matching, and chamber-to-chamber matching while developing advanced RF control strategies.
• Define verification and validation plans; support prototype bring-up, design reviews, system qualification, and customer demonstrations.
• Use circuit analysis, electromagnetic modeling, power-loss analysis, impedance matching, thermal and reliability assessments, and experimental correlation to guide technical decisions, supplier qualification, corrective actions, and product roadmaps.

Requirements

• BS, MS, or PhD in Electrical Engineering, Physics, RF Engineering, or a related discipline.
• 8+ years of experience developing RF systems in semiconductor equipment, plasma processing, power electronics, communications, aerospace, or related industries.
• Strong foundation in RF circuit design, electromagnetics, impedance matching, transmission line theory, and high-frequency power delivery systems.
• Experience with RF generators and matching networks.
• Hands-on troubleshooting and laboratory characterization experience.
• Proven ability to lead complex technical programs and cross-functional teams.
• Ability to mentor junior engineers, provide technical guidance, perform data-driven risk assessments, and present technical results to executive leadership and customers.

Nice to have

• Experience with semiconductor plasma processing, including PECVD, CVD, Etch, EPI, Surface Treatment, or related plasma applications.
