# Senior RF Engineer – Quantum Control H/F at Alice & Bob

- **Company:** Alice & Bob
- **Location:** Aubervilliers, France
- **Work type:** hybrid
- **Posted:** 2026-09-24
- **Last confirmed live:** 2026-10-17
- **Apply:** https://jobs.lever.co/alice-bob/fa74d8d1-58dc-49c5-b097-f0f2d6c80085

## Job description

Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems. The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈‍⬛. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!

We're a diverse team of 250+ brilliant minds from over 35 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!

Behind every stable qubit is a chain of RF hardware that has to perform flawlessly — and that's what you'll be building. In a context of rapid scale-up of Alice & Bob's quantum processors, you'll ensure that control electronics and RF instrumentation keep pace with the growing demands of qubit control. Reporting to the HERMES Team Lead, our electronics and systems integration team, you'll design, build and validate test setups and characterization benches — and, where existing commercial solutions fall short, design custom RF hardware (power amplifiers, LNAs, filters, bias tees) — to guarantee that every piece of equipment meets the precision and scalability needs of our quantum chip design teams.

Responsabilities

- Design custom RF hardware (power amplifiers, LNAs, filters, bias tees) and PCB front-ends where commercial solutions fall short, using 3D EM simulation to validate designs before prototyping
- Define measurement plans and build test setups and characterization benches, running V&V (mostly in Python) with VNAs, oscilloscopes, SMUs, and spectrum analyzers
- Design or upgrade existing RF/DC systems to evolving requirements (spectral purity, pulse shape, power stability) following the scale up of quantum processors and control channels
- Troubleshoot technical issues across instrumentation, control electronics, and PCB hardware, driving root-cause analysis when needed
- Work closely with Quantum Hardware Infra colleagues, physicists, and software engineers, keep an eye on the state of the art, and document your work as you go

## Requirements

- Master's or higher degree in Electrical Engineering, RF/Microwave Engineering, Physics, or a related field
- 5+ years of experience in RF design, characterization, and control electronics, including PCB design
- Strong RF design and signal processing skills (signal integrity, modulation/demodulation, filtering, noise/distortion analysis), with hands-on experience designing RF PCBs and using 3D EM simulation tools
- Comfortable with FPGA integration for control electronics, and with RF/electrical test equipment (VNAs, oscilloscopes, spectrum analyzers, SMUs, signal generators)
- Python skills for test automation and remote instrument control (e.g. SCPI)
- Strong troubleshooting mindset and root-cause analysis skills
- Excellent communication and cross-functional collaboration skills
- Proficient in English; French is a plus

Remote work possible depending on specific ongoing tasks.

## Nice to have

- Experience with cryogenic or quantum environments, knowledge of KiCad/Altium/HFSS, scientific writing

Recruitment process

- Screening call with Alexandra, Talent Acquisition (30 min)
- Interview with Clément Hiring Manager (60 min)
- Technical interview with the team (60 min)
- Leadership and fit interview (60 min)

Benefits:

- Our success is your success: own it with our BSPCE plan
- Direct IP Compensation: Earn substantial bonuses for driving the core patents that define our quantum architecture.
- A Parental plan including additional benefits such as crèche support or additional days-off to take care of under 12 years old children
- Subsidized membership with Urban Sports Club
- Mental health support with moka.care
- 25-day vacation policy (as per French law) + RTT
- Half of transportation cost coverage (as per French law), or yearly allowance for the die-hard bicycle users
- Competitive health coverage, with Alan.
- Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen
- French language courses covered by the company for those interested

Research shows that women might feel hesitant to apply for this job if they don't match 100% of the job requirements listed. This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec.

You will join of one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer!

We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow.

## About Alice & Bob

## Company Overview
- **One-liner**: Alice & Bob is a French quantum computing company designing superconducting cat qubits—a type of qubit inherently protected from bit-flip errors—to build a universal, fault-tolerant quantum computer.
- **Entity Type**: Private (Series B–II)
- **Headquarters**: Paris, France (with offices in Boston, MA)
