About SirenOpt
SirenOpt helps manufacturers make better, safer, and more reliable micro- and nano-materials. These materials are the building blocks of critical sectors of the global economy such as batteries, computer chips, aircraft components, and power systems. But, surging material demand and growing complexity are pushing production to unprecedented scales and speeds, leaving manufacturers effectively flying blind. Small, undetected variations during production lead to wastage, lower performance, higher costs, and safety risks.
SirenOpt is changing this. Our manufacturing intelligence platform scans materials, revealing critical internal information without damaging them. Using a novel combination of cold atmospheric plasma, physics-informed machine learning, and predictive analytics, SirenOpt creates unique, real-time fingerprints that capture material signals no other method can access. These insights give manufacturers unprecedented visibility into how materials behave as they are made.
We turn hidden data into actionable intelligence to help manufacturers reduce variability and thus increase yield and performance. The technology can be deployed as a standalone tool or integrated directly into factory production lines. SirenOpt is currently deploying early versions of its platform with some of the largest industrial manufacturers in the world across North America, Europe, and Asia. Our first commercial product will be released in 2026.
Role Overview
SirenOpt is looking for a Quality Manager to lead the development and implementation of quality control systems. As our first dedicated Quality Manager, you will build and own our Quality Management System (QMS) from the ground up, lead us through ISO 9001 certification, and embed quality processes into the way we design, build, and deliver products.
This is a hands-on, high-impact role for someone who enjoys working cross-functionally across an organization, solving hard problems quickly, and helping shape quality in a startup environment.
You will be the quality leader within the company and support company goals and objectives while maintaining a strict adherence to ensuring the quality of incoming, intermediate, and outgoing materials.
What You’ll Do
QMS Design & ISO 9001 Certification
