Quantum Integration Staff Engineer

Role details

In the Advanced Technology Services (ATS) group at SkyWater, our team works hand in hand with customers to develop a wide range of exciting new, novel, and fully customized technologies - including superconducting ICs, quantum computing devices, carbon nanotube devices, MEMs, Bio sensors, DNA sequencing devices, Si photonics, and III-V devices. We are seeking a Quantum Integration Staff Engineer to join our quantum photonics hardware team, working on the fabrication and integration of photonic devices in a semiconductor foundry environment.

This role sits at the intersection of process engineering, device physics, systems integration and photonic platform creation — bridging wafer-level fabrication with functional quantum photonic hardware for networking, sensing, and computing applications.

Responsibilities

Develop and optimize fabrication process flows for wafer level manufacturing of low-loss photonic waveguides, ensuring seamless execution Lead or support III-V-on-silicon (or III-V-on-photonics) heterogeneous/hybrid integration efforts Develop, characterize and integrate high-speed electro-optic modulators into photonic circuits Support integration of components relevant to quantum applications: single-photon sources/detectors, or cryogenic-compatible photonics Collaborate with process integration teams to troubleshoot yield, optical loss, and reliability issues across the fab flow Develop test and characterization methodologies for waveguide loss, modulator bandwidth, coupling efficiency, and device-level quantum metrics Interface with cross-functional teams (customer, design, process, packaging, test) to ensure manufacturability of quantum photonic devices Document process recipes, integration flows, and failure analysis for internal knowledge transfer and process control Collaborate with CAD engineers to validate incoming layout files, constructing frames with essential metrology boxes and electrical test structures.

Implement data collection schemes and collaborate with process and tool experts to formulate effective process recipes. Design and conduct experiments to validate and optimize process recipes. Liaise with the failure analysis lab to submit samples for cross-sectioning, contributing to continuous improvement. Monitor customer material and proactively address processing issues, ensuring a smooth workflow. Conduct regular meetings with customers, providing updates on project progress as materials move through the production line. Deliver process reviews with the goal of transitioning the device to full-scale production.

Required Qualifications

BS, MS, or PhD in Electrical Eng, Materials Science, Chemical Eng, Physics, Optical Engineering or related discipline Experience with cleanroom fabrication tools (lithography, etch, deposition, CMP, metrology) BS and 5 years, or MS and 3 years, or PhD and 0-3 years of engineering experience in a semiconductor fab or lab environment. Basic knowledge of semiconductor fabrication and equipment. Strong organizational skills and work ethic. Exceptional oral and written communication skills. Ability to thrive in a large cross-functional program environment.

US Citizenship Required: This position will require the holding of or ability to obtain government security clearance which requires U.S Citizenship.
