Product Engineer

Permanent employee, Full-time · Delft

Your mission

Qblox is looking for a Product Engineer to help us deliver high-quality control stacks for quantum computers. These quantum control stacks generate the analogue 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 analogue 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 Product Engineer, you’ll be part of the Product Engineering team, but you will also work with and support most other teams. The position requires a very broad set of skills. Among other things, you will be involved in the process in which the designs will be made ready for serial production including design-for-manufacturing and design-for-testing services of external partners, investigating setting up assembly/packaging instructions, handling of repairs and RMAs, lifecycle management, outsourcing production, and issue investigation. Furthermore, you will make sure our products will get the necessary certifications required to run in quantum laboratories around the world.
