The Mission

At Qubic, we are dedicated to the advancement of superconducting quantum sensing and quantum computing. Our focus as a company is on the transition from theory and design of device physics to the realization of high-performance hardware that can reshape quantum measurement. We are looking for a Nanofabrication Scientist to serve as a core technical specialist in our tech team. This is a role for someone who values the systematic nature of cleanroom work, enjoys the complexity of process integration, has interest in the challenges of commercialization, and finds excitement in creating devices, characterizing them, and working in a team to improve scalable quantum hardware.

The Role

As a foundational member of our fabrication team, you will contribute to and refine the end-to-end process of our superconducting device realization. You will serve as a bridge between materials physics, microwave circuit design, and cryogenic device characterization, working closely with the engineers and physicists on our design and measurement teams to ensure that our superconducting films meet the highest standards of performance, uniformity, and stability, and that our devices provide powerful measurement outcomes for our partners. You will be responsible for optimizing thin film deposition, improving and exploring lithography processes, participating in device design and strategy, managing and conducting sample characterization workflows, and establishing the fabrication recipes that allow our hardware to scale to industrial cleanrooms.

The Impact: Why This Role Matters

This role is at the heart of our technical roadmap and involves a good dose of innovation and exploration as part of our core technical team. By refining our superconducting device properties and addressing the critical challenge of process stability, you ensure that every piece of hardware Qubic produces is consistent, documented, and ready for commercial-grade applications. Your success directly impacts our collective ability to scale, turning lab-bench breakthroughs into a reliable production pipeline.
