If you're excited to work on breakthrough technology in a fast-paced, hands-on environment, we'd love to hear from you.

We are seeking a Senior DSP Engineer to join our team and play a pivotal role in shaping the future of quantum technology. Based on system goals, this engineer will design algorithms for instrument control.  This task will combine information from high-level requirements and direct laboratory measurements to address system goals. You will be responsible for developing custom algorithms for systems with limited resources.

In addition, this role requires an individual to develop test plans to extract empirical data that will amplify simulation results. While initially focused on research and development, the ultimate objective is to transition to commercial devices. The ideal candidate is a strong individual contributor who can take ownership of their tasks while also supporting the overall team goals.

Requirements What You'll DoWork with a cross-functional team of physicists, EEs, mechanical engineers, and optical engineers to create next-generation quantum instruments.

Design signal processing algorithms for precision sensors.
The work will include implementations in both CPUs and RTL-based FPGA systems. Work with various simulation tools to define and validate customized signal-processing algorithms for a wide-range of sensor applications. Work in a team to develop implementations that meet system-level requirements in limited-resource embedded systems.  Assist with the translation into RTL or Firmware implementations.  Define experiments to characterize plant behavior, measure performance metrics, and system identification.

Collaborate with EEs and Software engineers to identify issues and debug systems.

What We're Looking For Bachelor’s or Master’s degree in Science, Technology, Engineering, or Mathematics (STEM) and five (5) years of experience relevant to signal processing.  Expert understanding of theory and the practical implementation of signal processing.  The candidate should have practical experience with most of the following digital signal…
