Development Engineer

Applications are invited for a Development Engineer at Toshiba Europe Ltd, based in Cambridge UK. The successful applicant will work in a team developing and manufacturing high speed quantum cryptographic systems. They will be responsible for designing next generation quantum cryptographic systems, testing optical/electrical components and sub-systems, assessing performance of assembled systems and working with key customers and partners on developing solutions. Appropriate training will be given.


  • Development of quantum cryptographic systems
  • Characterising optoelectronic components
  • System-level test of optical communication hardware
  • Working with global network of partners and customers

Mandatory requirement:

  • Degree level qualification in Physics, Electronics, IT, or a related discipline
  • Good communication skills
  • Able to work individually or as a team member
  • Attention to detail


  • Knowledge of computer control programming environments, e.g., LabVIEW/C/C++.
  • Familiar with Linux operation system

Background information:

Keeping personal data safe and secure is one of the greatest challenges posed by the rapid development of today’s information technology. To meet this challenge, Quantum Key Distribution (QKD) has emerged as a revolutionary technology that allows the distribution of digital keys needed for data protection with security guaranteed by the laws of quantum physics. Unlike existing technologies based on public key cryptography, QKD is future proof and is not vulnerable to technological advances in mathematics, engineering and computing power, or even the development of a quantum computer.

Toshiba Europe Limited has been at the leading position in the development of high speed QKD systems in the past decade. It has developed the first Quantum Cryptography system operating over 100 km of fibre and the first to operate with a secure key rate of 10 Mbit/sec. Toshiba’s systems have been selected to serve long-haul fibre links in the first UK Quantum Network.

Applicants should send a CV, contact details of three referees and a covering letter, to:

Dr A J Shields, Assistant Managing Director

Industrial CASE PhD Studentship in Quantum Photonics

Applications are invited for an industrial CASE studentship at Toshiba Europe in Cambridge working in the area of photonic quantum technology and its applications.

TEUR have a world leading activity investigating components and systems for Quantum Technology applications. We seek researchers to join our team to work on novel schemes for quantum key distribution, entanglement-based long distance quantum communication and high rate single photon detection and its applications.

We have PhD projects available in the areas of quantum communications and semiconductor quantum photonics. Candidates should hold (or expect) a first degree in Physics, Electronic Engineering or other relevant discipline. They will have demonstrated academic success at the highest level, creativity, enthusiasm and shown an aptitude for experimental Physics or Engineering.

Applicants should send (as soon as possible) a covering letter, CV and contact details of two referees to:

Dr A J Shields, Assistant Managing Director
Toshiba Europe Ltd., Cambridge Research Laboratory
208 Science Park, Milton Road, Cambridge CB4 0GZ, UK
