Architect and develop analog and mixed-signal electronics for compact, high-performance hardware modules, using TIAs, ADCs, precision current sources, and power supplies like LDOs and switching regulators. Own designs from concept through production, including schematic capture, component selection, and PCB layout in collaboration with layout engineers. Ensure signal integrity, power integrity, and EMI/EMC compliance across high-speed and noise-sensitive interfaces. Define and execute bring-up, characterization, and validation plans (e.g., DVT, EVT), with a focus on robustness, repeatability, and manufacturability. Analyze design trade-offs in the context of tightly constrained product architectures. Partner with system architects, mechanical engineers, and firmware teams to ensure seamless integration and system-level reliability.
