Job Description

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 Enough about us, what about you? In order to really enjoy this role, we imagine you have a background encompassing the following: The Track Record: You hold a degree in Electrical Engineering and have at least 5 years of professional experience pushing the limits of PCB design. Hands-on experience with high-speed digital PCB design and simulation Ability to debug complex hardware systems at board and system level Solid background in RF circuit design, simulation and measurements Tool Mastery: You are an expert in Altium Designer and proficient with simulation tools like ADS or SPICE. Lab Fluency: You are at home with Oscilloscopes, Spectrum Analyzers, and VNAs, and you use Python for testing and data analysis. Technical Depth: You have a solid background in RF circuit design and a deep understanding of low-noise, low-drift measurement circuits.

Core Responsibilities

Design, simulate, test, and debug high-performance digital, RF, and low-noise analog hardware, including multilayer PCBs and measurement circuits. Lead prototype characterization and validation, resolve signal and noise issues, document designs, and collaborate with firmware and software teams throughout product development.

Requirements

Requires a degree in Electrical Engineering and at least five years of professional PCB design experience, including hands-on high-speed digital design and simulation. Candidates should have strong RF design and measurement expertise, understand low-noise and low-drift circuits, be proficient in Altium Designer and simulation tools such as ADS or SPICE, and use lab instruments and Python for testing and analysis.
