Staff RF Design Engineer

Job Title

Staff RF Design Engineer

Role Summary

Design and validate RF and mixed-signal IC blocks for sub-GHz to 2.4 GHz radio systems, working at both block and system level. Join an international team developing low-power wireless solutions used in LoRa/LoRaWAN devices.

Work is split between hands-on circuit design, simulation, lab characterization, and cross-functional integration to meet performance and regulatory requirements.

Experience Level

Senior (Staff) level. The posting specifies 3+ years of semiconductor industry experience; senior technical leadership and system-level contributions are expected.

Responsibilities

Core responsibilities include design, verification, measurements, and cross-team collaboration:

• Lead design, simulation, and optimization of RF and baseband blocks (majority of effort).
• Perform lab measurements, device characterization, bring-up and debug of prototypes.
• Provide ATE/test support and contribute to regulatory compliance assessments.
• Work at both block and system level to ensure radio performance across sub-GHz to 2.4 GHz bands.
• Collaborate with digital, firmware, system, test, and manufacturing teams to meet product requirements.
• Contribute to specifications, design reviews, and release testing.
• Provide technical mentorship and guidance to engineering peers.

Requirements

Must-have technical skills and experience (education summarized separately below).

• 3+ years semiconductor industry experience in RF/CMOS IC design.
• Practical CMOS IC design expertise for RF and mixed-signal blocks across sub-GHz to 2.4 GHz.
• Hands-on experience with one or more of: LDOs/regulators, bandgap references/power-on-reset, ADCs (Σ-Δ, SAR), LNAs, mixers, filters, power amplifiers.
• Lab measurement and characterization experience; familiarity with ATE support and test plan development.
• Strong problem-solving skills and a collaborative working style.
• Proficiency in English; French is a plus.

Nice-to-have:

• RC and crystal oscillator design experience.
• Knowledge of ESD protection strategies.
• Mixed-mode circuit simulation experience (e.g. Symphony or equivalent).
• EM simulation tools experience (SiWave, HFSS, EMX).

Education Requirements

Degree in Electronics Engineering (degree level not specified in the posting). A Master's or PhD with 5+ years' experience is listed as preferred. No specific certifications were mentioned; no explicit "equivalent experience" phrasing provided.
