Senior RF/Analog Design Engineer

Arago is an AI and computer hardware company whose mission is to drive the course of history forward. We do so by accelerating breakthroughs at the intersection of AI and semiconductors.

Founded in 2024 by AI researchers and physicists with deep expertise in photonics, electronics, software, mathematics, and machine learning, Arago brings together a lean team of engineers and scientists from the world’s top companies and research labs.

Composed of nine nationalities and operating from hubs in France, North America, and Israel, we believe in great science and fast achievements. Our work is guided by these core principles:

1. Do great things: we deliver work we’re proud to sign our name to.

2. High velocity: speed matters. We move quickly, one step at a time.

3. One unit: we’re all in this together, with relationships grounded in trust, respect, and camaraderie.

Arago is backed by executives from Apple, Arm, Nvidia, Microsoft, and Hugging Face, as well as prominent US and European deeptech venture firms and exited founders.

Design high-performance analog and RF ICs optimized for precision, power, and area, driving Arago’s prototype and product iterations from architecture to silicon validation.

• →

  Design and simulate analog and RF integrated circuits, including critical blocks such as amplifiers, mixers, PLLs, ADCs, DACs, and bias/reference circuits, with a focus on signal integrity, linearity, and precision.

• →

  Optimize circuits for power, area, and performance trade-offs, ensuring designs meet system-level requirements across process, voltage, and temperature (PVT) variations.
