About the job

Job Title: Staff Electrical Engineer – FPGA / MPSoC Systems & Digital Signal Processing

Location: On-site (San Leandro, CA)

Job Type: Full-time

Role Overview

SirenOpt 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.

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 sensing, digital signal processing, and control concepts into robust, high-performance, field-ready systems.

What You’ll Do

• Lead the architecture, design, implementation, and validation of FPGA, MPSoC, and FPGA-based digital signal processing systems for SirenOpt's metrology platform.

• Develop designs from concept through architecture definition, RTL development, modeling, simulation, verification, testbench development, bench testing, and system bring-up.

• Build and maintain robust simulation and verification environments to validate functionality, timing, performance, and reliability at both block and system levels.

• Design 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.

• Implement, evaluate, and refine signal-processing and control algorithms such as PID, ADPLL, filtering, and signal-conditioning methods for high-performance measurement systems.

• Use MATLAB and Python for algorithm development, modeling, data analysis, system validation, and signal and electrical data characterization.

• Perform large-scale data analysis to evaluate signal quality, characterize system behavior, and guide design tradeoffs and performance optimization.

• Collaborate closely with hardware, electrical, software, algorithm, and systems engineers to support end-to-end FPGA, MPSoC, firmware, and hardware integration.

• Read and interpret schematics to understand board-level architecture, interfaces, signal paths, power domains, and subsystem dependencies.

• Bring 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.

• Help translate frontier R&D concepts into scalable, reliable, and manufacturable digital systems.

What We’re Looking For

• B.S., M.S., or PhD in Electrical Engineering, Computer Engineering, or a related field, with 5+ years of relevant industry experience.

• Strong experience with end-to-end FPGA and MPSoC design, including architecture, RTL development, simulation, synthesis, timing closure, verification, and board bring-up.

• Advanced experience with FPGA-based digital signal processing for real-time systems, including FIR filters, synchronization methods, streaming pipelines, and control-oriented digital design.

• Strong experience with algorithm modeling and analysis using MATLAB and Python.

• Experience implementing and validating signal-processing and control techniques such as PID, ADPLL, filtering, and signal characterization workflows.

• Strong command of HDL/RTL implementation for digital signal processing, control, and high-performance data-path design.

• Hands-on experience developing testbenches, verification environments, and bench-level validation workflows.

• Strong understanding of firmware/hardware integration and system-level debugging in tightly coupled digital platforms.

• Ability to read and understand electrical schematics and work effectively at the board and subsystem level.

• Proven experience troubleshooting and bringing up hardware in the lab using standard electrical test equipment.

• Experience working in a fast-moving, multidisciplinary environment with a high degree of ownership and technical independence.

• Strong communication skills and a practical, problem-solving mindset.

Nice to Have

• Experience providing technical leadership for hardware and firmware engineering teams in complex product development environments.

• Experience with image processing or vision-related algorithm pipelines.

• PCB design experience, including familiarity with board-level layout considerations and signal integrity tradeoffs.

• Experience with high-speed interfaces, instrumentation systems, or real-time sensing platforms.

• Familiarity with mixed-signal systems and integration with ADCs, DACs, sensors, and embedded processors.

• Exposure to metrology systems, scientific instrumentation, or advanced materials applications.
