About SirenOptSirenOpt 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.
Role OverviewSirenOpt is looking for a Staff Electrical Engineer - High Voltage Systems to help architect, design, and validate the high-voltage electrical systems behind our next-generation metrology platform.
This is a hands-on, high-impact role for someone who enjoys working close to the technology, solving hard problems quickly, and helping shape products in an early-stage startup environment.
This role is ideal for an engineer who is energized by deep tech, thrives in cross-functional environments, and is motivated by the opportunity to build something genuinely new.
You will work closely with a small, highly capable team to turn advanced plasma science into robust, manufacturable, field-ready systems.
What You'll Do- Lead and contribute to the electrical design and validation of SirenOpt's plasma-based metrology systems.
- Design high-voltage and mixed-signal electronics from concept through schematic capture, layout guidance, bring-up, debug, testing, and integration.
- Collaborate with mechanical, systems, software, algorithm, and project engineers to develop reliable and scalable products.
- Research and evaluate new concepts, components, and architectures for advanced low-temperature plasma instrumentation.
- Work closely with customers and internal stakeholders to refine designs based on real-world use, integration needs, and product feedback.
- Create and maintain core technical documentation, including requirements, schematics, wiring diagrams, validation plans, and test reports.
- Help translate frontier R&D into practical hardware that can perform in demanding industrial environments.
What We're Looking For- B.S., M.S., or PhD in Electrical Engineering or a related field, with 5+ years of relevant industry experience.
- Strong experience in high-voltage PCB design, ideally above 5 kV.
- Hands-on experience across the full PCB development cycle, including concept, schematics, layout, manufacturing support, bring-up, testing, and HW/SW integration.
- Experience with mixed-signal designs that combine analog, digital, and high-voltage circuitry.
- Familiarity with DfX practices such as DFM and DFT, along with structured engineering review processes.
- Ability to work effectively in a fast-moving, multidisciplinary environment with a high degree of ownership.
- Strong communication skills and a practical, problem-solving mindset.
Nice to Have- Experience in electron optics, electron beam systems, plasma systems, or similar high-voltage applications.
- Familiarity with CE, UL, or other regulatory compliance frameworks.
- Experience with high-precision industrial systems used in metrology, automation, or advanced material processing.
- Exposure to metrology sensors or instrumentation for advanced materials.
Why Join SirenOpt- Help define a new category in advanced materials metrology.
- Work on genuinely novel deep-tech hardware with real scientific and industrial impact.
- Join an early-stage team where your decisions directly shape the product, technology, and company.
- Build systems at the intersection of plasma science, electronics, sensing, and AI-driven analytics.
- Contribute to technology that can expand what researchers and industry teams are able to see, measure, and optimize.
