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.
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.
What You’ll Do
• Define and own system-level architecture, integration, and validation of SirenOpt’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 guide system integration
and resolve non-trivial cross-disciplinary issues
• Incorporate customer and application feedback into system-level design evolution
and validation strategy
• Support on-site installation, validation, and system upgrade activities at customer
sites as needed
• Domestic and international travel of approximately 10–15% is expected.
What We’re Looking For
• B.S. in Engineering or Physics with 7+ years of relevant industry experience, M.S.
with 5+ years, or Ph.D. with 3+ years of hands-on systems experience• Experience developing automated metrology, inspection, or diagnostic systems
across system definition, integration, validation, deployment, and customer support
• Experience working in early-stage or ambiguous R&D environments, using
experimentation and data analysis to evaluate concepts and guide system-level
decisions
• Proficiency with tools such as Python, MATLAB, C, LabVIEW, or similar for data
analysis, modeling, and evaluation of system performance
• Extensive hands-on experience developing, integrating, and validating prototypes,
subsystems, and complete systems
• Experience working across mechanical, electrical, software, and experimental
domains to resolve complex integration and performance issues
• Demonstrated ability to guide technical direction through experimentation, data-
driven analysis, and cross-disciplinary evaluation
• Experience establishing or evolving technical documentation practices, ensuring
clarity, consistency, and traceability of experimental results and system decisions
• Strong written and verbal communication skills, particularly in documenting
complex technical work clearly for diverse audiences
Nice to Have
• Experience with manufacturing metrology equipment and sensors used for
characterization or fabrication of advanced materials
• Experience with requirements and test management tools (e.g., Jama or similar)
and data analysis software such as JMP
• Experience with early-stage R&D and/or new product introduction (NPI) in complex
technical systems
• Exposure to high-precision, high-throughput industrial systems for material
handling, metrology, or process automation
• Prior work or research experience in one or more of the key industrial markets that
SirenOpt addresses, including batteries, semiconductors, power generation, energy,
or electronics
• Familiarity with high-voltage devices; exposure to plasma-based systems
• Experience with capital equipment designed for integration into manufacturing
environments, particularly roll-to-roll and piece-to-piece processes
