About SirenOpt
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.
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.
We developed PlasmaSens™, our manufacturing intelligence platform, to close that visibility gap and to lay the foundation for truly autonomous manufacturing.
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.
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.
About the job
Job Title: Metrology Applications Engineer
Location: On-Site (San Leandro, CA)
Job Type: Full-Time
Role Overview
SirenOpt is seeking a Metrology Applications Engineer to join our Customer Solutions Engineering team. This role combines hands on technical work in SirenOpt's labs and at customer sites with direct, face to face engagement with customer engineering and operations teams.
You will help to demonstrate and develop new capabilities and use cases for SirenOpt's PlasmaSens metrology platforms. This includes working with customers understand, deploy, and extract value from SirenOpt's metrology platforms by designing and executing demonstration studies, interpreting results, and translating insights into clear recommendations. We welcome driven materials characterization and metrology specialists who want to make a tangible impact on advanced manufacturing and the green energy transition, and we strongly encourage candidates from underrepresented groups to apply.
What You'll Do
-
Work directly with customers, prospects, and collaborators to understand material and product metrology requirements, then scope, plan, and execute appropriate demonstration studies and proof of concepts.
-
Design, run, and analyze experiments in SirenOpt's labs and at customer facilities, including test planning, data collection, and interpretation of metrology results.
-
Present findings in a clear, structured way to customer engineers, managers, and executives, and collaborate on next step plans based on the results.
-
Support installation, commissioning, and optimization of PlasmaSens systems at customer sites, including basic troubleshooting and performance verification.
-
Provide structured feedback from field deployments and customer interactions to SirenOpt's product and engineering teams, influencing roadmap and usability improvements.
-
Explore and identify new applications, performance capabilities, and product features that expand the product and market opportunities for SirenOpt's platform.
-
Contribute to the development and continuous improvement of internal methodologies, calibration procedures, and best practices for metrology workflows.
-
Create and maintain concise documentation (application notes, standard operating procedures, quick start guides, etc.) for customers and internal teams.
What We're Looking For
-
B.S. or M.S. in materials science, chemical engineering, chemistry, physics, or a closely related technical discipline; or a Ph.D. in a relevant field.
-
For B.S./M.S. candidates: 1-2 years of industry experience in manufacturing, metrology, materials characterization, and/or materials development (coatings or precursor materials experience is a plus).
-
For Ph.D. candidates: research or industry experience directly related to materials characterization, materials fabrication or coating, or advanced manufacturing.
-
Experience working with hardware and software in an industrial or manufacturing context (e.g., lab instrumentation, in line sensors, analytics tools).
-
Familiarity with data analysis, unsupervised/supervised ML, and statistical process concepts (e.g., SPC, Gauge R&R, basic modeling, trend analysis) and comfort using tools like JMP, Matlab, and/or Python.
-
Strong interpersonal skills and confidence interacting face to face with customers, including on shop floors, in labs, and in conference rooms.
-
Ability and willingness to travel (up to ~25%) for customer site work, installations, and conferences.
-
Clear written and verbal communication skills, including the ability to explain technical concepts to mixed technical/non technical audiences.
-
Adaptability and enthusiasm for working in a fast paced, multidisciplinary environment where priorities can shift based on customer needs.
Nice to have:
-
Prior work or research experience in one or more of SirenOpt's key industrial markets (batteries, aerospace, power generation, semiconductors, energy, electronics).
-
Exposure to plasma processing, high temperature materials, or in situ/on line metrology systems.
-
Fluency in one or more stakeholder languages (e.g., Japanese, Mandarin Chinese, Korean, German, French).
Benefits
- Equity and Salary compensation depends on experience
- Health, Dental, Vision plans provided
- 401k matching provided
- Time off: 20 days of PTO per year, plus approximately 15 paid US holidays per year
