Staff Electrical Engineer - High Voltage Systems

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. The 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 Ph.D. 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. Benefits Equity and salary compensation depends on experience. Health, dental, and vision plans provided. 401(k) matching provided. Time off: 20 days of PTO per year, plus approximately 15 paid U.S. holidays per year. Actual compensation within the pay range listed will be decided based on factors including skills and prior relevant experience. Base Pay Range
