Staff Quality Engineer

<div class="content-intro"><p><strong>About SirenOpt</strong></p> <p><span data-contrast="auto">At SirenOpt®, we are building the manufacturing intelligence layer for advanced materials. We help manufacturers visualize, understand, and control the material behavior that determines yield, performance, and safety across energy, aerospace, automotive, electronics, and semiconductor applications.</span><span data-ccp-props="{"335559738":240,"335559739":240}"> </span></p> <p><span data-contrast="auto">We are working on this problem because advanced materials are becoming more critical and more complex, but the tools used to manufacture them have not kept pace. Manufacturers still lack real-time visibility into the small variations that shape quality on the line. We care because those invisible variations cause scrap, waste energy and materials, create higher costs, inconsistent product performance, and introduce avoidable safety risks.</span><span data-ccp-props="{"335559738":240,"335559739":240}"> </span></p> <p><span data-contrast="auto">We developed PlasmaSens™, our manufacturing intelligence platform, to close that visibility gap and to lay the foundation for truly autonomous manufacturing.</span><span data-ccp-props="{"335559738":240,"335559739":240}"> </span></p> <p><span data-contrast="auto">We are uniquely suited to solve this problem because our expertise and our platform connect material science, plasma physics, machine learning, and manufacturing in one system.  The same core technology works in-line, at-line, and off-line, and across form factors ranging from electrodes and wafers to 3D components. That flexibility lets us meet manufacturers where they are and carry insight from the lab into mass production.</span><span data-ccp-props="{"335559738":240,"335559739":240}"> </span></p> <p><span data-contrast="auto">We have deployed multiple PlasmaSens products with customers and collaborators across the United States, Japan, Germany, and Taiwan.  We pair that real-world experience with support from leading US, European, and Japanese venture investors, the National Science Foundation, the California Energy Commission, and the Department of Energy.  Our combination of differentiated technology, manufacturing experience, and global scientific and industry partnerships gives us the foundation to solve material variability at scale.</span><span data-ccp-props="{"335559738":240,"335559739":240}"> </span></p></div><p><strong>About the job</strong></p> <p><strong>Job Title:</strong> Staff Quality Engineer</p> <p><strong>Location:</strong> On-Site (San Leandro, CA)</p> <p><strong>Job Type:</strong> Full-Time</p> <p><strong>Role Overview</strong></p> <p>SirenOpt is seeking a<strong> Staff Quality Engineer</strong> to establish and scale quality practices that support exceptional product quality across the organization.
