Senior HPC Engineer

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!

Drive performance improvements of scientific computing tools using SOTA HPC techniques across CPU and GPU architectures in both cloud and on-premises environments.

Profile, diagnose, and resolve performance bottlenecks at all levels (e.g., algorithm design, software implementation, hardware-level optimization).

Build and scale distributed simulation pipelines to support increasingly complex quantum system models.

PhD or Master’s degree in scientific computing, applied mathematics, or computer science.

5+ years of experience in designing, developing, testing, maintenance, and performance optimization of production-grade scientific software, including a minimum of 2 years in an industrial environment.

Strong programming expertise in Python, JAX and Rust.

Demonstrated HPC skills, spanning CPU parallelization (MPI, OpenMP), GPU computing, scheduling and orchestration of workloads across heterogeneous systems, performance profiling and optimization.

Good knowledge of finite precision arithmetics and numerical methods for linear algebra.

Professional-level English proficiency, both written and spoken.
