Job description

Join Our Team as a Hardware Validation Engineer at Qblox!

At Qblox, we operate at the frontier of the quantum revolution, and 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 18 GHz), our signals must exhibit exceptional performance with minimal noise, temperature drift, and interference.

Your experience as a Hardware Validation Engineer will play a pivotal role in the expansion to our next generation system.

Our R&D team tackles complex challenges, and you will test, characterize, validate and debug high‑performance electronic hardware, working at the intersection of high‑speed digital, RF, and ultra‑low‑noise measurement systems.

This role requires deep expertise in circuit analysis, experience with automated test frameworks, and mastery of lab equipment.

Joining Qblox means becoming part of a dynamic, international team where innovation thrives. Collaboration is at the heart of our culture — ideas are shared, creativity is encouraged, and solutions are crafted together. You will have the autonomy to explore, experiment, and make meaningful contributions that directly impact the trajectory of our projects.

If you want to push the boundaries of technology, thrive in a collaborative environment, and play a key role in building the next generation of quantum computing hardware, we’d love to hear from you.

Key Responsibilities

• Create comprehensive test plans based on hardware specifications for characterization and validation measurements
• Initial board bring‑up of new PCBAs
• Debug hardware prototypes, identifying and resolving signal integrity, noise, and performance issues
• Perform characterization and validation measurements of high‑speed digital, RF, and low‑noise analog PCBAs to ensure all the requirements are met
• Develop and maintain automated test frameworks to increase test coverage and efficiency
• Collaborate with design, firmware, and software engineers to debug issues, analyze data, and ensure the design meets requirements
• Generate and maintain detailed technical documentation and validation reports
• Mentor and guide junior engineers

Skill Requirements

• Minimum of 5 years of professional experience
• Solid background in RF circuit design, simulation and measurements
• Mastery of lab equipment (e.g. oscilloscopes, spectrum analyzers, VNAs, etc.)
• Proficiency in Python for testing and data analysis
• Ability to debug complex hardware systems at board and system level
• Deep understanding of signal integrity and power integrity principles
• Experience with Altium Designer
• Familiarity with Agile methodology and Jira issue tracking systems
• Strong problem‑solving and analytical skills, with attention to detail
• Highly motivated, proactive, and a collaborative team player with a creative “can‑do” mentality
• Excellent communication skills in English (full professional proficiency, written and spoken)
