Senior RF/Analog Design Engineer

Job Title

Senior RF/Analog Design Engineer

Role Summary

Design high-performance analog and RF integrated circuits for Arago's prototype and product iterations, taking designs from architecture through silicon validation. Work closely with optics, simulation, PCB, and layout teams to ensure system-level performance and integration.

Experience Level

Senior level. The title indicates a senior role; no explicit years-of-experience requirement was listed.

Responsibilities

Key responsibilities include circuit design, cross-team integration, and supporting silicon bring-up and verification.

• Design and simulate analog and RF IC blocks (amplifiers, mixers, PLLs, ADCs, DACs, bias/reference circuits) with emphasis on signal integrity, linearity, and precision.
• Optimize circuits for power, area, and performance across process, voltage, and temperature (PVT) variations.
• Define architecture and block-level specifications in collaboration with optics, simulation, and PCB teams to meet prototype and product goals.
• Guide floor-planning and physical design with layout engineers to minimize parasitics and preserve analog precision.
• Support post-silicon validation and bring-up: define test plans, analyze lab measurements, and correlate results with simulation to refine designs.
• Communicate engineering decisions and results in English; French is a plus.

Requirements

Must-have technical skills and experience required for the role; nice-to-have items follow.

• Must-have: Strong mathematical foundation and physical intuition of analog electronics, including voltage↔current conversion at low and high frequencies.
• Proven experience designing high-precision analog systems for signal processing or power electronics; experience with high-frequency analog signals is valued.
• Extensive IC design and post-layout design methodology experience using industry tools such as Cadence Virtuoso.
• Proficiency in mixed-signal circuit design and optimization, including ADCs and DACs across low (kHz–MHz) and high (>GHz) frequency ranges, and in signal conditioning circuits.
• Strong understanding of signal integrity, crosstalk mitigation, and noise-reduction techniques in mixed-signal and RF systems interfacing with digital processors.
• Advanced-node IC design experience required (process nodes <28nm).
• Nice-to-have: Prior collaboration experience with optics, PCB, or system-simulation teams; French language skills.

Education Requirements

Not specified.
