Hardware/Embedded Test Engineer

Qblox is looking for a Test Development Engineer to help us deliver high-quality 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 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.


As a Test Development Engineer, you’ll be part of the Test & Automation Team. You’ll be helping establish an automated testing process of our products in-house. This includes defining test strategies, designing and building modular test setups, developing scalable software for these setups, and analyzing test results. You’ll work under the supervision of the Test & Automation Lead.

Gevraagd wordt

  • Master's or Bachelor's degree
  • Experience with various test and measurement equipment
  • Solid experience with at least one programming language, preferably Python or C# (NI LabVIEW experience is appreciated)
  • Good understanding of OOP
  • Experience with test automation tools and frameworks, ideally including OpenTAP (NI TestStand experience is appreciated)
  • Experience defining test strategies
  • Ability to document things in a structured way
  • Ability to review and be reviewed in a structured way
  • Comfortable with Git
  • Comfortable with command line
  • Experience with issue tracking systems, ideally Jira
  • Experience with CI/CD, ideally GitLab
  • Affinity with electronics and signal processing
  • Embedded domain experience is a plus
  • RF domain experience is a plus

At Qblox we celebrate equality and diversity. We’re striving to build a team that represents a variety of backgrounds, cultures, perspectives, experiences, and skills. If you are to join us, you can expect:

  • An international, interdisciplinary team of high-skilled physicists, engineers, designers and scientists with an open working culture 
  • A high-curiosity, high-performance and invigorating team dynamic 
  • Flexible working hours: hybrid working options and travel allowance for commute
  • 30 days annual leave and holiday allowance
  • Company-sponsored retreats and Friday lunches
  • Modern, open office with proximity to QuTech facilities, shared with Delft-based quantum startups
  • Competitive compensation and participation plan
  • Opportunities for international travel for conferences, partnerships and customer visits


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.
