Senior Hardware Design Engineer

**Senior Hardware Design Engineer** **Broadata Communications, Inc. (BCI) – Torrance, CA** *On-site* **Company Overview** **Broadata Communications, Inc. (BCI)** is a privately held California-based corporation. BCI is a leading and innovative company specializing in the development of market-driven products for the transmission of digital multimedia (video, audio, and data) over fiber. Our clients are world leaders in their industries, spanning entertainment, broadcast, medical, professional audio/video, house of worship, education, government, military, and transportation sectors. We are ISO 13485 and ISO 9001 certified, with a strong commitment to quality, innovation, and continuous improvement. **Summary** We are seeking a hands-on **Senior Hardware Design Engineer** to design, simulate, bring up, and validate complex mixed-signal and high-speed digital hardware for BCI multimedia, video-over-IP, fiber optic, medical, enterprise, and mission-critical products. This role focuses on schematic design, PCB layout, high-speed circuit simulation, signal integrity, power integrity, DFM/DFT review, board-level troubleshooting, and production release. Strong Altium Designer experience is required. Experience using Ansys HFSS for high-speed interconnect, via, connector, launch, transition, and channel simulation is a plus. This is a hands-on role based in Torrance, CA, and is not a remote or hybrid position. We offer a fast-paced, high impact and stimulating environment with opportunities for professional growth within BCI. Veterans welcome! **Key Responsibilities** - Own board-level hardware design from requirements review, architecture definition, component selection, schematic capture, PCB layout support, prototype bring-up, DFM/DFT review, verification, and production release. - Create and maintain complex multi-sheet schematics in Altium Designer for video, high-speed digital, embedded processor, FPGA/CPLD, power, analog, isolation, protection, and fiber optic interface circuits. - Own or directly support PCB layout in Altium Designer, including component placement, stack-up definition, controlled impedance, design rules, routing constraints, length matching, differential-pair tuning, return-path control, via strategy, and manufacturability review. - Define and review high-speed layout requirements for HDMI, DisplayPort, USB-C/USB 3.x, DVI, 3G/12G SDI, SFP/SFP+, 1G/10G Ethernet, PCIe, DDR2/DDR3/DDR4, LVDS, MIPI, and similar multi-Gbps interfaces. - Perform pre-layout and post-layout high-speed circuit simulation and SI/PI analysis to reduce jitter, crosstalk, insertion loss, return loss, reflections, via stubs, impedance discontinuities, EMI risk, and power noise. - Use Ansys HFSS or similar 3D EM tools when applicable to analyze connectors, high-speed launches, vias, back-drill structures, transitions, stubs, and other critical discontinuities. HFSS experience is a plus. - Use simulation and layout review to guide connector selection, cable interface design, ESD/EMI protection, common-mode choke usage, reference-plane continuity, grounding, shielding, and high-speed routing strategy. - Design and review power architecture, switching and linear power supplies, sequencing, protection circuits, thermal considerations, and power-distribution networks for reliable embedded products. - Lead board bring-up, debug, and root-cause failure analysis for prototypes, pilot builds, sustaining engineering changes, EOL redesigns, and customer RMA issues. - Use oscilloscopes, TDR/VNA, protocol analyzers, BERT/eye-diagram tools, logic analyzers, thermal tools, and standard lab equipment to validate high-speed, power, and embedded hardware performance. - Support verification and validation testing, including HDMI/DP/SDI/Ethernet interface checks, EMC/ESD testing, environmental stress screening, reliability testing, and compliance-related testing for medical or mission-critical products. - Prepare and review ECO/ECN packages, BOMs, manufacturing…
