At Alice & Bob, we're building the world's first fault-tolerant quantum computer, powered by our unique cat qubit architecture. Our team of passionate scientists and engineers is at the forefront of quantum computing, working together to achieve breakthroughs that will shape the future of technology.

To achieve this, our enabling technologies (like control electronics, microwave components, and cryogenic systems) must evolve to match the complexity of scaling quantum computing. That's where you come in.

As an R&D Engineer, you'll be a key player in driving the evolution of these critical systems. Working closely with physicists, production teams, and external partners, you'll lead projects to benchmark, select, and deploy innovative technologies. Your work will be vital in transforming our systems to meet industrial-scale performance and reliability standards.

Your Mission:

• Lead projects focused on advancing enabling technologies for quantum computing.
• Define and design cutting-edge electronic systems that meet evolving needs.
• Scout and integrate the latest innovative technologies into our subsystems.
• Establish quality procedures that enable scalability and meet industry standards.

A Little About You:

• You hold an engineering degree (or University equivalent) or a PhD, with around 5 years of experience in industry.
• You have hands-on experience with project management and complex technical systems.
• You bring a blend of rigor, adaptability, and a collaborative spirit to every challenge.
• You're proactive, autonomous, and always eager to learn and grow.
• You're a good communicator, comfortable discussing complex topics with both technical and non-technical audiences.

Bonus points if you have experience across one or multiple fields such as quantum physics, analog/digital electronics, signal processing, cryogenics, or high-performance computing.
