Inno Phase Inc., DBA Green Wave Radios™, is at the forefront of innovation in Open RAN digital radios. Powered by the Hermes
64 RF SoC, our solutions enhance network energy efficiency while dramatically reducing operational expenses. Headquartered in San Diego, California, we have a team of over 100 engineers across four global R&D facilities, with more than 120 global patents in radio technology.

We are seeking a highly skilled Senior Staff RF/Hardware Design Engineer to lead the development of advanced 5G radio hardware. The ideal candidate has in-depth expertise in RF circuit design, system integration, and validation for wireless infrastructure or user equipment, and has proven experience delivering high‑performance designs from concept through production.

Working closely with cross‑functional teams—system architects, digital designers, and firmware engineers—you will define and implement next‑generation 5G hardware platforms that push performance, reliability, and efficiency limits.

• Lead the design and development of RF (frontend, transceiver) and supply circuits for 4G and 5G  (sub‑6 GHz) systems.
• Perform schematic capture, component selection, simulation, layout review, and design optimization for performance, manufacturability, and cost.
• Define and execute RF test plans, including S‑parameter, noise figure, linearity, P1dB, IIP3, VSWR, and ACLR measurements.
• Drive PCB design reviews, ensuring proper RF layout techniques, grounding, impedance control, and thermal design.
• Collaborate with system and baseband teams to define RF system architecture, interfaces, and calibration requirements.
• Conduct signal integrity and power integrity analysis for high‑speed digital and mixed‑signal sections.
• Support bring‑up, troubleshooting, and validation of prototypes in the lab.
• Provide technical mentorship to junior engineers and contribute to long‑term hardware roadmap planning.

• Master’s degree in Electrical Engineering, Electronics, or related field.
• 12+ years of hands‑on experience in RF/hardware design for wireless communication systems.
• Strong knowledge of RF circuit design, including LNAs, PAs, mixers, PLLs, filters, power supply, clock, and matching networks.
• Experience with RF simulation tools (Keysight ADS, Cadence AWR, or equivalent).
• Proficiency with schematic capture and PCB layout tools (Cadence Allegro, Altium, etc.).
• Solid understanding of RF specifications, including performance metrics.
• Hands‑on lab experience with RF instruments: vector network analyzers, spectrum analyzers, signal generators, and oscilloscopes.
• Experience in system‑level debugging and hardware bring‑up.
• Excellent problem‑solving and communication skills, with strong collaboration ability in cross‑functional teams.

• Experience with mass‑production design for 5G infrastructure, small cells, or mobile platforms.
• Understanding of thermal design and mechanical constraints in RF systems.
• Experience with EMC/EMI design and compliance testing.
• Advanced degree (Ph.D.) in RF/Microwave Engineering or related field.
