Radio Frequency System Engineer

Rydberg Technologies is seeking a dynamic Senior Radio Frequency (RF) Systems Engineer to lead the design, development, and deployment of next-generation RF systems at the intersection of advanced electromagnetics, software‑defined architectures, and quantum sensing. This is a hands‑on, high‑ownership technical leadership role responsible for building novel antenna and front‑end architectures, advanced signal processing pipelines, and direction‑finding capabilities that push the limits of state‑of‑the‑art RF engineering.

You will work closely with a cross‑functional team of quantum physicists, hardware engineers, and software developers to architect and deliver integrated RF–quantum sensor systems, translating cutting‑edge research into engineered products. The ideal candidate is innovative, execution‑driven, comfortable with both system‑level planning and meticulous technical detail, and thrives in a fast‑paced environment where first‑of‑a‑kind technology is built.

We are looking for individuals who are solution‑oriented, deeply organized, self‑motivated, and capable of working both independently and collaboratively while contributing to a bold roadmap in quantum‑enabled RF sensing.

• Design, develop, and implement novel antenna front‑ends hardware and RF electronics.
• Software‑defined radio (SDR) solutions for advanced RF applications, leveraging GPU acceleration and RF machine learning techniques.
• Collaborate with physicists and hardware engineers to design and optimize antenna and electronic systems for various RF applications.
• Define and validate specifications of RF systems, antenna receivers, to ensure optimal performance.
• Design and implement RF electronics for RF systems, such as frequency synthesizers, power amplifiers, and RF switches, to meet system requirements.
• Conduct RF test and measurement activities, including RF characterization, performance testing, and validation, using RF test equipment.
• Research, analyze, and evaluate RF waveforms to develop algorithms and models for signal identification, classification, and direction finding.
• Integrate RF systems with quantum sensors to explore new sensing capabilities and applications.
• Provide technical expertise and guidance to junior engineers and support staff.
