YOUR MISSION
Qblox is looking for a Senior Digital Design Engineer to help us deliver control stacks for quantum computers. These quantum control stacks generate the analog signals needed for the control and readout of quantum bits. The signals have frequencies spanning the range from DC to the microwave regime (~20 GHz) and need to have extremely low noise, temperature drift and interference. To reach these analog properties as well as stringent timing criteria in quantum computing, signals are generated using high-end FPGAs connected to high-speed data converters. Furthermore, it is required that the control stack is scalable and can grow to accommodate larger quantum processors. Our products are compatible with a range of quantum computing hardware technologies like superconducting qubits and semiconductor qubits.
As a Senior Digital Design Engineer, your primary role is to help design and implement the FPGA firmware required for the products we develop. You will also assist in the implementation of the embedded software. We have developed a soft-core sequence processor that is responsible for the deterministic generation of (RF) pulses with ns accuracy that are used for the control and readout of qubits. We use DSP techniques to modulate these pulses in the real-time signal path before sending them to the data converters. We are constantly adding functionality to our designs to, for example, extend the instruction set of the sequence processor. These additional features allow us to use the technology not only to drive quantum computers, but also allow us to use the products for the development of quantum networks, also referred to as quantum internet.

ABOUT US
With a dedicated team of scientists, engineers and developers we are pushing quantum technology to support experimentalists worldwide with our scalable and low-latency qubit control and readout equipment from ultrastable DC to 18.5 GHz for academic and industrial quantum labs. In addition to scalable control hardware, we have created state-of-the-art control software – Quantify, an open-source python framework that can be used to control quantum computers and experimental setups.
Qblox is a young and fast-growing company with the mission to enable the quantum revolution. We are a spin-off from QuTech (a collaboration between Delft University of Technology and TNO) based in Delft, a historical city in The Netherlands located between The Hague and Rotterdam. You will join a highly-skilled and motivated team. We are shaping the future and have a lot of fun while doing so!
