Company

hirify.global commercialises quantum computing research from the Cavendish Laboratory and develops quantum photonic technology for scalable quantum networking infrastructure.

What you will do

• Design, develop, and verify RTL code for Xilinx Zynq and Ultrascale devices using SystemVerilog, Verilog, VHDL, and/or Migen.
• Develop and verify embedded code in C or Rust and real-time control systems using ARTIQ Sinara hardware.
• Collaborate with software, electronics, hardware, optical engineering, and physics specialists to define requirements and develop hardware subsystems.
• Debug multi-node quantum networking systems and contribute to tools that provide in-system visibility into real-time systems.
• Prepare design documentation, test plans, and technical reports.
• Automate tool flows, CI/CD pipelines, and release processes.
