Role Overview SirenOpt 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.
