Test Development Engineer (Hardware/Embedded)

Permanent employee, Full-time · Delft

Your mission

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.

Your profile
  • 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
