Job Type: Full-Time

Siren Opt 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.

Siren Opt 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, Siren Opt 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. Siren Opt is currently deploying early

versions of its platform with some of the largest industrial manufacturers in the world

across North America, Europe, and Asia.

We are seeking a Staff Systems Engineer to define, integrate, and validate Siren Opt’s

plasma-based sensing platform for deployment into advanced manufacturing

environments. As an early-stage member of the Siren Opt 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.

• Define and own system-level architecture, integration, and validation of Siren Opt’s plasma-based sensing platform
• Guide system-level technical decisions through experimentation, data analysis, and cross-disciplinary evaluation
• Lead investigation and resolution of complex system performance issues through structured experimentation, data analysis, and root cause analysis
• Establish and evolve the structure used to document experiments, system designs, interfaces, and technical decisions across the organization
• Ensure technical documentation is clear, consistent, and traceable, and tightly integrated with hands-on engineering and validation activities
• Work closely with cross-functional engineering teams to…
