Symmetric Encryption Reborn for the Cloud

Opto-mechanical Engineer – London, Southeast England

We have a Purpose: we use transformational quantum encryption technology to keep safe the data of our governments, enterprises and citizens. You can be a part of that purpose.  Join a team where every member is valued in our work solving a big problem impacting people and outcomes around the globe.  Our business is about trust in data and we start with trust in you.

Arqit has brought together a world-leading team of pioneers in engineering and cryptography, and we now have an opportunity for a Quantum/Photonics Specialist. The role may involve working in our London office or in our regional operations centre, and there will be considerable flexibility around working from home; there will also be some (not extensive) business travel.  We believe that inclusivity makes us a stronger, happier team, with better decision-making and greater ability to connect with all customers, and we are committed to maintaining a working environment which is welcoming and supportive.


Arqit has a new opportunity for a passionate physicist or engineer, with research and applied experience of quantum information systems and/or photonics, to support realisation of our innovative QKD system. This will be an exciting role as a specialist working closely with our senior engineers, skilled academic and industrial partners, to deliver genuinely cutting-edge technology from the laboratory into the real-world environment.

The role could be adapted to suit the level of experience of the successful applicant. We encourage applications from senior, mid and early career candidates.
