43 jobs for “Advanced R&D Scientist - Quantum Algorit”
Join the Runtime Software team to build the real-time control system that turns quantum hardware into a working computer. You'll develop Rust libraries and abstractions over real-time control devices, driving ions with nanosecond precision, and work closely with experimental scientists and compiler teams.
Rust
Integrate all features needed to operate quantum computers into complex multi-layer chips, taking designs from requirements through layout and tape-out. Work closely with scientists and fabrication engineers on ion trapping chips, routing metal tracks and interfacing with photonics and CMOS, while owning project delivery independently.

PsiQuantum · 501–1000 people · Late stage
Interns in the optical architecture group work at the interface of hardware, manufacturing and quantum architecture, prototyping software to control and simulate optical networks inside photonic quantum computers. They apply quantum information theory, network design and optimisation to improve designs, simulate and benchmark protocols, and document results. Placements run 3-6 months on a rolling basis, with a mix of analytical and programming work.
