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 by developing a manufacturing intelligence platform that non-destructively probes materials during production, revealing critical internal information without damaging them. Using a novel combination of cold atmospheric plasma, physics-informed machine learning, and predictive analytics, SirenOpt generates unique, real-time material fingerprints that capture material signals not accessible through conventional measurement techniques. 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.

About the job

Job Title: Senior/Staff Systems Engineer

Location: On-Site (San Leandro, CA)

Job Type: Full-Time

Role Overview

We are seeking a Staff Systems Engineer to define, integrate, and validate SirenOpt's plasma-based sensing platform for deployment into advanced manufacturing environments. As an early-stage member of the SirenOpt team, you will play a key role in shaping system-level behavior and ensuring technical coherence across hardware, software, and experimental domains, helping establish a strong and scalable technical foundation for the company.

This role carries responsibility both for system-level technical ownership and for shaping how technical work is documented across the organization. You will define and evolve the structure used to document experiments, system designs, interfaces, and technical decisions, ensuring clarity, consistency, and traceability as the company grows. These documentation practices are expected to be tightly coupled to hands-on engineering work, including experimentation, data analysis, and system validation.

The ideal candidate applies sound systems engineering judgment to complex, cross-disciplinary problems and is comfortable operating in areas of ambiguity. You will drive system-level trade studies, guide experimental strategy, and resolve non-trivial integration and performance issues, while remaining deeply engaged in day-to-day technical execution. This role offers an opportunity to operate at a high level of technical impact in a collaborative and fast-moving engineering environment.
