Embedded Systems & FPGA Engineer (all genders)

zerothird is a Vienna-based deep-tech company specialising in entanglement-based Quantum Key Distribution (eQKD). Our technology - rooted in Nobel Prize-winning research on quantum entanglement - enables encryption keys to be generated locally from entangled photon states, making interception physically impossible.

We develop and deploy the full hardware and service stack for quantum-secure communications, targeting critical infrastructure, financial institutions, and government organisations across Europe.

As part of our next-generation hardware platform development, we are looking for an experienced Embedded Systems & FPGA Engineer to join our core engineering team.

If you are excited about building cutting-edge quantum communication technology at the intersection of embedded Linux and FPGA development, we would love to hear from you. 1 Embedded Systems & FPGA Engineer (all genders) Key Responsibilities
