FPGA Design Engineer

Our client is a technology-oriented company developing advanced quantum networking hardware and photonic technologies for next-generation quantum computing systems. The organization develops highly integrated engineering solutions designed to improve the scalability, performance, and practical deployment of quantum information systems.

Its activities combine electronics, photonics, physics, nanofabrication, mechanical engineering, software, and FPGA development within a highly multidisciplinary environment. The company operates from early-stage concepts and circuit development through laboratory testing, system integration, and prototype deployment, offering engineers the opportunity to work on technically demanding hardware at the forefront of quantum technology.

The FPGA Design Engineer will be responsible for developing, verifying, and supporting FPGA-based real-time control systems for quantum networking applications. The role will contribute to existing hardware platforms based on ARTIQ and the Sinara hardware ecosystem while supporting the development of next-generation control infrastructure incorporating White Rabbit technology, working closely with senior engineers and multidisciplinary technical teams.
