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.
Job Description
We are seeking a Senior Systems Engineer to help develop, test, and validate SirenOpt’s plasma-based sensing platform for integration into advanced manufacturing environments. As an early-stage member of the SirenOpt team, you will have the opportunity to make a direct impact on next-generation material characterization technologies while helping build a strong technical foundation for a growing company.
The ideal candidate learns new concepts quickly and produces high-quality technical work with strong attention to documentation. You will apply sound engineering judgment to solve a wide range of technical challenges efficiently and creatively, often spanning multiple disciplines. A core part of this role is planning and executing experiments, analyzing results, and maintaining thorough documentation. Some problems may fall outside your core areas of expertise, making technical curiosity, hands-on experimentation, and a self-starting mindset critical for success.
This role offers an exciting opportunity to work with cutting-edge systems in a collaborative and dynamic environment. If you are a driven and skilled engineer who enjoys hands-on system development, disciplined experimentation, and data-driven problem solving, we encourage you to apply.
In this role you will:
- Support system-level design, integration, and validation of SirenOpt’s plasma-based sensing platform
- Work with a small, cross-functional engineering team to research, develop, and validate new system concepts and experimental approaches
- Plan and execute experiments to characterize system performance and sensitivity to environmental and operational factors
- Analyze experimental data and maintain clear, well-organized documentation of experimental work and results
- Contribute to technical design documentation, including requirements, specifications, test plans, schematics, and test reports
- Incorporate customer and application feedback into experimental studies and system design iterations
- Support on-site installation, testing, and validation of SirenOpt instruments at customer sites as needed
- Domestic and international travel of approximately 5–10% may be required.
You have:
- B.S. in Engineering or Physics with 5+ years of relevant industry experience, M.S. with 2+ years, or Ph.D. with relevant hands-on experience
- Experience developing automated metrology, inspection, or diagnostic systems through design, validation, deployment, and customer support phases
- Experience designing and executing structured experiments, including multi-dimensional Design of Experiments (DoE)
- Proficiency with tools such as Python, MATLAB, C, or similar for data analysis, modeling, and evaluation of system performance
- Hands-on experience developing and testing prototypes, subsystems, and integrated systems
- Experience working with suppliers or external partners in a technical support or collaboration capacity
- Experience incorporating customer or application feedback into experimental studies and design iterations
- Experience performing sensitivity analysis and using results to inform design improvements and mitigation strategies
- Ability to adapt to new technical challenges and operate effectively in a fast-paced, multidisciplinary environment
- Strong written and verbal communication skills, including clear technical documentation
Nice to have:
- Experience with metrology equipment and sensors used for characterization of advanced materials
- 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 is a plus
- Experience with capital equipment designed for integration into manufacturing environments, particularly roll-to-roll and piece-to-piece processes
- Exposure to high-precision, high-throughput industrial systems for material handling, metrology, or process automation
- Japanese language proficiency
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
