GreenWave Radios•San Diego, CA

8d•Onsite

About The Position

InnoPhase Inc., DBA GreenWave Radios™, is a pioneer in Open RAN digital radios, utilizing the Hermes64 RF SoC to create energy-efficient and cost-effective solutions for ORAN-based active antenna arrays. Headquartered in San Diego, California, the company has over 100 engineers across four global R&D facilities and holds more than 120 global patents. GreenWave Radios™ is seeking a Staff Hardware Design Engineer to design and develop PCB circuitry for next-generation cellular base stations. This role involves integrating custom silicon, including digital processing, high-speed SerDes, power management, and RF transmission/reception, into high-reliability and power-efficient solutions. It is a hands-on position with increasing ownership, requiring execution of PCB design from schematic to production and collaboration with analog, digital, and RF experts.

Requirements

8+ years of relevant experience designing mixed signal circuits in a hardware engineering role
BSc in Electrical Engineering or equivalent experience/training
Proven track record in PCB schematic and layout design, ideally in high-speed and RF/analog applications
Hands-on experience with Cadence Allegro
Solid grasp of signal integrity, power integrity, and thermal management principles
Working knowledge of PCB fabrication processes and DFM best practices
Strong foundation in both analog and digital electronics
Experience mentoring junior designers and sharing technical knowledge across the team
Excellent cross-functional collaboration and communication skills — you'll work daily with experts across multiple domains

Nice To Haves

Ability to thrive in a fast-paced environment where innovation must align with real-world constraints
Exposure to AI-assisted EDA tools for schematic capture, layout optimization, or DFM checking
Comfort using AI copilots (e.g., Cadence's AI/ML-enabled Allegro features, or general LLM tools) to speed up documentation, datasheet parsing, or design-rule research
General comfort adopting AI-augmented workflows to boost design productivity — this is a plus, not a requirement, for the right hands-on RF/analog expert

Responsibilities

Execute PCB development from concept through production, with increasing ownership over design decisions
Design and implement RF, analog, digital, and power circuits for high-performance base station products
Collaborate with domain experts on floor planning and PCB constraints for seamless integration
Own schematic capture and PCB layout, and participate in design reviews
Optimize PCB stack-up for performance and cost
Develop and maintain schematic symbols and component footprints
Contribute to and improve the PCB development flow for better quality and productivity
Participate in PCB vendor engagement and DFM reviews
Drive board bring-up and debug, escalating complex issues with structured analysis
