Responsibilities

High-Speed PCB Design & Signal Integrity

• •Lead the physical design of complex, multi-layer PCBs for the TeraWave network switch platform.
• •Perform pre- and post-layout signal integrity (SI) analysis, including SerDes lanes, DDR memory buses, and high-density Ethernet switch interconnects.
• •Apply advanced PCB design techniques including:
• •Controlled impedance routing for differential pairs and single-ended high-speed signals.
• •Via structures to minimize stub lengths and optimize signal path routing in high-density designs.
• •Dielectric material — understanding how material affects differential pair skew and impedance variation and applying strategies.

• •Define and review PCB layer stack-ups in collaboration with PCB fabricators, specifying laminate materials, prepreg selection, copper weights, and via structures to meet SI, power integrity, and manufacturing reliability and yield requirements including coupon testing.
• •Develop and execute full 3D electromagnetic (EM) simulation models of critical PCB structures extracting broadband S-parameter models that capture frequency-dependent losses, reflections, and crosstalk without reliance on simplified lumped element approximations.
• •Perform SI simulation to validate eye margins, crosstalk levels, and model accuracy versus physical measurement.
• •Apply de-embedding techniques and use VNA measurements and TDR analysis to correlate simulated SI results with physical hardware measurements.

DDR Memory Interface Design

• •Design DDR4, and/or DDR5 memory subsystems with a thorough understanding of fly-by topology, write leveling, read/write training, and the constraints imposed by the memory controller.
• •Understand and account for the PCB routing limitations of processor and microcontroller memory interfaces, including:
• •Byte lane grouping and skew budgets within and across DQ groups.
• •Address/command bus fly-by routing and stub minimization.
• •Reference plane continuity and return current management beneath DDR routing fields.

SerDes, Microprocessor & High-Speed Interface PCB Design

• •Design PCB layouts for high-speed serializer/deserializer (SerDes) interfaces including 10GbE, 25GbE, 40GbE, 100GbE, and beyond.
• •Experience in PCB design implementations for microprocessors and SoCs (ARM, RISC-V, MPSoC, or equivalent), understanding the physical routing constraints and signal integrity limitations of high pin-count BGA packages including escape routing, via-in-pad usage, and power delivery network design beneath the device.
• •Optimize high-speed connector and backplane interfaces for minimum via stub and maximum channel insertion loss margin.

Power Integrity Design & Verification

• •Architect and design low-impedance power delivery networks (PDNs) for high-current, noise-sensitive devices including switch ASICs, microprocessors, FPGAs, and DDR memory, with target impedance profiles defined across the full frequency range of interest.
• •Perform PDN simulation using frequency-domain tools to verify decoupling capacitor placement, value selection, and plane resonance suppression.
• •Execute power integrity (PI) measurements including VNA-based PDN impedance measurements, time-domain load transient validation, and switching noise characterization to verify simulated PDN performance against physical hardware.
• •Design multi-stage LC filtering and high-PSRR LDO post-regulation stages to isolate sensitive analog and high-speed digital supply rails from switching converter noise.
• •Apply plane-splitting, via stitching, and decoupling placement strategies to prevent power-plane noise coupling into high-speed signal paths.

PCB Design for Manufacturability (DFM) & Design for Testability (DFT)

• •Apply rigorous DFM practices throughout the PCB design process, including:
• •Via and pad structure selection compatible with the PCB fabricator's manufacturing capabilities (microvia aspect ratios, back-drill depth tolerances, controlled-depth routing).
• •Copper feature sizing, annular ring, and clearance rules consistent with the target fabrication class (IPC Class 2/3 as appropriate for space hardware).
• •Component placement and routing strategies that support automated optical inspection (AOI), X-ray inspection, and solder paste printing yield.

• •Implement comprehensive DFT strategies including:
• •Boundary scan (JTAG) chain architecture across the board for structural test coverage.
• •Dedicated test point placement for in-circuit test (ICT) and flying probe access to critical nets.
• •Built-in self-test (BIST) hooks at the PCB level in collaboration with firmware teams.
• •Test connector and loopback provisions for high-speed interface validation during board bring-up and manufacturing test.

• •Work closely with PCB fabricators and contract manufacturers during design review cycles to validate manufacturing feasibility before release to fabrication.
• •Demonstrate compliance through laboratory measurements.

Electromagnetic Capability (EMC)

• •Demonstrate working knowledge of electromagnetic compatibility (EMC) design principles encompassing all four fundamental compliance categories: conducted emissions, radiated emissions, conducted susceptibility, and radiated susceptibility.
• •Apply this understanding at the PCB design level through deliberate implementation of mitigation strategies including: strategic placement and selection of filter components on power entry and signal interface lines; chassis ground stitching via placement and guard trace strategies; shielding; and bulk decoupling and filtering power inputs designed to suppress conducted noise.
• •Demonstrate compliance through laboratory measurements.

Hardware Integration & Validation

• •Lead hardware bring-up and validation of the TeraWave switch PCB, including power sequencing, high-speed interface eye diagram characterization, BER testing, individual component compliance through environmental testing.
• •Develop and execute hardware validation test plans covering SI/PI measurements, functional test, and environmental screening as appropriate.
• •Support resolution of complex PCB-related hardware issues identified during bring-up, integrating root cause findings back into PCB design guidelines and DFM/DFT standards.
