We help manufacturers visualize, understand, and control the material behavior that determines yield, performance, and safety across energy, aerospace, automotive, electronics, and semiconductor applications. \nWe are working on this problem because advanced materials are becoming more critical and more complex, but the tools used to manufacture them have not kept pace. Manufacturers still lack real-time visibility into the small variations that shape quality on the line. We care because those invisible variations cause scrap, waste energy and materials, create higher costs, inconsistent product performance, and introduce avoidable safety risks. \nWe developed PlasmaSens™, our manufacturing intelligence platform, to close that visibility gap and to lay the foundation for truly autonomous manufacturing. \nWe are uniquely suited to solve this problem because our expertise and our platform connect material science, plasma physics, machine learning, and manufacturing in one system. The same core technology works in-line, at-line, and off-line, and across form factors ranging from electrodes and wafers to 3D components. That flexibility lets us meet manufacturers where they are and carry insight from the lab into mass production. \nWe have deployed multiple PlasmaSens products with customers and collaborators across the United States, Japan, Germany, and Taiwan. We pair that real-world experience with support from leading US, European, and Japanese venture investors, the National Science Foundation, the California Energy Commission, and the Department of Energy. Our combination of differentiated technology, manufacturing experience, and global scientific and industry partnerships gives us the foundation to solve material variability at scale. \nAbout the job\nJob Title: Staff Electrical Engineer - FPGA / MPSoC Systems & Digital Signal Processing\nLocation: On-site (San Leandro, CA)\nJob Type: Full-time\nRole Overview\nSirenOpt is looking for a Staff Electrical Engineer - FPGA / MPSoC & Digital Signal Processing Systems to lead the architecture, design, implementation, and validation of high-performance programmable logic, embedded processing, and FPGA-based digital signal processing systems powering our next-generation metrology platform.\nThis 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.\nThis 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.\nYou will work closely with a small, highly capable team to turn advanced sensing, digital signal processing, and control concepts into robust, high-performance, field-ready systems.\nWhat You’ll Do\nLead the architecture, design, implementation, and validation of FPGA, MPSoC, and FPGA-based digital signal processing systems for SirenOpt's metrology platform.\n\nDevelop designs from concept through architecture definition, RTL development, modeling, simulation, verification, testbench development, bench testing, and system bring-up.\n\nBuild and maintain robust simulation and verification environments to validate functionality, timing, performance, and reliability at both block and system levels.\n\nDesign and implement FPGA-based digital signal processing pipelines for real-time sensing and metrology applications, including FIR filters, synchronization pipelines, control loops, and low-latency data paths.\n\nImplement, evaluate, and refine signal-processing and control algorithms such as PID, ADPLL, filtering, and signal-conditioning methods for high-performance measurement systems.\n\nUse MATLAB and Python for algorithm development, modeling, data analysis, system validation, and signal and electrical data characterization.\n\nPerform large-scale data analysis to evaluate signal quality, characterize system behavior, and guide design tradeoffs and performance optimization.\n\nCollaborate closely with hardware, electrical, software, algorithm, and systems engineers to support end-to-end FPGA, MPSoC, firmware, and hardware integration.\n\nRead and interpret schematics to understand board-level architecture, interfaces, signal paths, power domains, and subsystem dependencies.\n\nBring up new boards in the lab, troubleshoot issues independently, and debug hardware/firmware interactions using oscilloscopes, logic analyzers, signal generators, power supplies, and related lab equipment.\n\nHelp translate frontier R&D concepts into scalable, reliable, and manufacturable digital systems.\n\nWhat We’re Looking For\nB.S., M.S., or PhD in Electrical Engineering, Computer Engineering, or a related field, with 5+ years of relevant industry experience.\n\nStrong experience with end-to-end FPGA and MPSoC design, including architecture, RTL development, simulation, synthesis, timing closure, verification, and board bring-up.\n\nAdvanced experience with FPGA-based digital signal processing for real-time systems, including FIR filters, synchronization methods, streaming pipelines, and control-oriented digital design.\n\nStrong experience with algorithm modeling and analysis using MATLAB and Python.\n\nExperience implementing and validating signal-processing and control techniques such as PID, ADPLL, filtering, and signal characterization workflows.\n\nStrong command of HDL/RTL implementation for digital signal processing, control, and high-performance data-path design.\n\nHands-on experience developing testbenches, verification environments, and bench-level validation workflows.\n\nStrong understanding of firmware/hardware integration and system-level debugging in tightly coupled digital platforms.\n\nAbility to read and understand electrical schematics and work effectively at the board and subsystem level.\n\nProven experience troubleshooting and bringing up hardware in the lab using standard electrical test equipment.\n\nExperience working in a fast-moving, multidisciplinary environment with a high degree of ownership and technical independence.\n\nStrong communication skills and a practical, problem-solving mindset.\n\nNice to Have\nExperience providing technical leadership for hardware and firmware engineering teams in complex product development environments.\n\nExperience with image processing or vision-related algorithm pipelines.\n\nPCB design experience, including familiarity with board-level layout considerations and signal integrity tradeoffs.\n\nExperience with high-speed interfaces, instrumentation systems, or real-time sensing platforms.\n\nFamiliarity with mixed-signal systems and integration with ADCs, DACs, sensors, and embedded processors.\n\nExposure to metrology systems, scientific instrumentation, or advanced materials applications.\n\nBase Pay Range\n$180,000—$220,000 USD\nBenefits\nEquity and Salary compensation depends on experience \nHealth, Dental, Vision plans provided\n401k matching provided\nTime off: 20 days of PTO per year, plus approximately 15 paid US holidays per year","description_format":"text","description_chars":7136,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["401k
