Join Our Team as an Electrical Engineer at Qblox!
At Qblox, we operate at the frontier of the quantum revolution, we are the leading provider of scalable and modular quantum control stacks that generate the analogue signals essential for controlling and reading out qubits in next-generation quantum computing and networking systems. Our work directly contributes to shaping the future of this revolutionary technology. Operating across frequencies spanning from DC to the microwave regime (up to 18GHz), our signals must exhibit exceptional performance with minimal noise, temperature drift, and interference.
Your experience will play a pivotal role in the expansion to our next generation system. As an Electrical Engineer in our R&D team, you will tackle complex challenges. You will simulate, design, test and debug high-performance electronic hardware used in quantum research environments, working at the intersection of high-speed digital, RF, and ultra-low-noise measurement systems. This role requires deep expertise in PCB design, simulation, and measurement, with a strong focus on signal integrity, noise performance, and reliability in cutting-edge quantum experiments.
With hybrid working and three weeks a year you can work from abroad, you’ll have the flexibility to fit your life. Whether that’s an extended break, visiting home, or just changing scenery. You’ll also get plenty of autonomy over your role grows and how the work gets done, without layers of red tape.
On top of that, you’ll be part of a tech space that’s genuinely rare-quantum control systems. It’s a chance to build expertise in a field that’s only just beginning to take off, while working alongside some of the sharpest minds in the sector.
Key Responsibilities
- Design, simulate, test and debug high-speed digital, RF, and low-noise analog PCBs
- Create multi-layer PCB designs, including schematic capture, layout, and design reviews
- Perform signal integrity and power integrity simulations for high-speed and RF designs
- Design and implement low-noise, low-drift and low-frequency measurement circuits
- Bring up, test, and debug hardware prototypes, identifying and resolving signal integrity, noise, and performance issues
- Support hardware development from early concept through prototype, validation, and production readiness
- Develop and implement test plans for characterization measurements
- Collaborate closely with firmware and software engineers to ensure seamless hardware-software integration
- Generate and maintain comprehensive technical documentation
- Mentor and guide junior engineers and provide technical expertise during the product development lifecycle
