Operations Associate

Liquid Instruments builds next-generation test and measurement technology for engineers and scientists pushing the boundaries of discovery.

Founded by scientists from the Australian National University, with research roots connected to NASA’s Jet Propulsion Laboratory, Liquid Instruments grew out of advanced physics and instrumentation research. Today, the company applies deep expertise in high-speed digital signal processing to deliver software-defined test and measurement platforms that replace racks of traditional lab equipment with a single, reconfigurable device—combining flexibility, performance, and cost efficiency through FPGA-based hardware and intuitive software.

Liquid Instruments operates globally, with teams in San Diego, California and Canberra, Australia. We are a growing, venture-backed company with a collaborative, technically curious culture that values ownership, clarity, and impact across time zones.

We are recruiting an Operations Associate to keep our daily operations running smoothly while helping us build the systems that will support our growth. You will own core fulfillment tasks and support order and inventory management. You will also take on technical projects, from building Hub Spot workflows and reports to automating manual processes and finding practical ways to use AI in our work.

This role is ideal for someone who is reliable with day-to-day essentials and enjoys fixing the root cause of a problem rather than working around it.
