Senior RF/Analog Design Engineer

About the role

Arago is seeking a Senior RF/Analog Design Engineer to lead the development of high‑performance analog and RF integrated circuits. You will work on cutting‑edge silicon prototypes, turning architectural concepts into silicon‑validated products.

Key responsibilities

• Design and simulate analog and RF IC blocks such as amplifiers, mixers, PLLs, ADCs, DACs, and bias/reference circuits.
• Optimize circuits for precision, power consumption, area, and performance across PVT variations.
• Collaborate with optics, simulation, and PCB teams to define architecture and block specifications.
• Guide layout engineers on floor‑planning and physical design to minimise parasitic effects.
• Support post‑silicon validation, create test plans, analyse measurements and feed results back into design iterations.

Required profile

• Strong mathematical background and deep physical intuition of analog electronics.
• Experience designing high‑precision analog systems for signal‑processing or power‑electronics applications.
• Proficiency in English; French is a plus.

Required skills

• Analog and RF IC design expertise.
• Design of amplifiers, mixers, PLLs, ADCs, DACs, and bias/reference circuits.
• Signal‑integrity, linearity and precision analysis.
• Power, area and performance trade‑off optimisation.
• Post‑layout design methodology using Cadence Virtuoso.
• Mixed‑signal circuit design at kHz‑MHz and >GHz frequencies.
