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!

The team:

The Pulse Team is responsible for developing the low-level software stack that controls the hardware systems enabling our physicists to conduct cutting-edge quantum experiments and eventually be at the core of our quantum computer.

About the role:

As a Senior Software Engineer, you will play a pivotal role in designing, developing, and maintaining robust, high-performance software solutions at the core of our technology. Acting as a technical leader within the team, you will drive architectural decisions, champion engineering best practices, and mentor junior engineers to support their professional growth. You will be in charge of developing the low level of our stack, as close as possible to our hardware.

Your work will be central in bridging scientific R&D, data engineering, and production-grade platform design while enabling researchers and physicists to iterate rapidly without compromising reliability.

Benefits:

• - Our success is your success: own it with our BSPCEplan
• - Direct IP Compensation:Earn substantial bonuses for driving the core patents that define our quantum architecture.
• Flexibleremotepolicy, up to 40 % a month
