Sr. Electrical Engineer (PCB Design & Bring-Up)
Fremont, CA
Full-time
Onsite
Senior Level, Lead/Staff
8+ years expSoundThinking is a company specializing in AI-powered weapons-detection systems. They are seeking a Senior Electrical Engineer to lead hardware design from architecture to production, ensuring reliability and performance in embedded systems.
Public Safety
Responsibilities
Architect new mixed-signal embedded systems (power, sensing front-end, compute interfacing, comms, connectors) aligned with SafePointe performance and reliability targets
Own schematic capture + component selection (availability, cost, lifecycle, derating) and define stack-up and critical constraints for layout
Drive PCB layout direction (Altium/KiCad or equivalent), including grounding strategy, return paths, isolation, connectorization, and noise/EMI control
Lead design reviews and sign-off on layout quality (placement, routing, PDN, high-speed constraints, manufacturability)
Execute board bring-up from first power-on to full functional validation: power sequencing, rails verification, clock/reset bring-up, firmware flashing paths, JTAG/SWD/UART/console access, boot diagnostics, boundary checks, subsystem validation (ADC/DAC, sensors, comms, storage, peripherals)
Build repeatable bring-up checklists, failure trees, and “known-good” reference measurements
Own power integrity (PDN impedance, ripple/noise, transient response) and signal integrity for relevant high-speed interfaces; translate results into actionable layout + design changes
Use simulation and lab correlation workflows (pre/post-layout) with industry toolchains (e.g., HFSS/ADS/Sigrity/SIwave class tools) as appropriate
Lead lab validation using oscilloscopes, VNAs, TDRs, spectrum analyzers, and related instrumentation; create detailed test plans and correlate with simulation
Drive root-cause analysis from bench to field: reproduce, isolate, fix, and prevent regressions
Ensure boards are manufacturable and testable: define DFM/DFT requirements, fixtures, boundary-access strategy, programming methods, and production test procedures
Partner with manufacturing, suppliers, and contract manufacturers to transition designs to volume builds
Work tightly with firmware, mechanical, ML/edge, and field operations teams to deliver integrated systems that hit performance, cost, and reliability targets
Qualification
Required
B.S. (or higher) in Electrical Engineering (or equivalent practical experience)
8+ years professional experience designing and shipping embedded hardware products
Demonstrated ownership of full PCB lifecycle: architecture → schematic → layout direction → bring-up → validation → production support
Strong mixed-signal fundamentals (analog + digital), power design, grounding, and EMI/EMC awareness
Proven track record of hands-on bring-up and debugging with lab equipment; strong documentation discipline
Experience creating test plans and structured validation methods for hardware
Preferred
SI/PI depth: experience with high-speed interfaces (e.g., PCIe/DDR/Ethernet/USB-class constraints), plus lab validation and correlation to simulation
Familiarity with SI/PI modeling toolchains (HFSS/ADS/Sigrity/SIwave or equivalents)
Experience building automation scripts (Python/bash) for data collection, test orchestration, and analysis
Track record delivering products into manufacturing and improving field reliability through disciplined release and regression prevention practices
Prior work with ruggedized or safety-critical deployments (UL/FCC/CE, ISO 9001, or similar environments)
