You will be responsible for the design and development of analog and mixed-signal electronics supporting PIXCEL's photonic modules. You will: • Design precision analog circuits, including op-amp topologies, low-noise amplification stages, current sources, and filtering networks. • Design power supply architectures, including buck converters, switching regulators, and LDO linear regulators. • Perform schematic capture and PCB layout in Altium Designer, including component library management and design-rule-driven workflows. • Lay out high-speed digital interfaces such as PCIe (differential pairs, impedance control, AC coupling) and LVDS signaling, with attention to signal and power integrity. • Bring up and debug boards using oscilloscopes, logic analyzers, and power analyzers to diagnose issues down to the component level. • Collaborate with optical, electrical, mechanical, and software engineers on integrated product designs. Who you'll work with: You will be part of a multi-disciplinary start-up team, including optical, electrical, mechanical, and software engineers. You will work closely with PIXCEL's silicon photonics development leads. The position is based in Matawan, NJ. Who you are: You have deep expertise in analog and mixed-signal circuit design and enjoy taking a board from schematic through bring-up. You are enthusiastic about engineering and seeing your efforts contribute to innovative products for real-world applications. You are excited about the opportunity to help build a great company. You are hands-on and enjoy working in a lab environment. You can work independently, but you value a friendly, team-oriented, collaborative work environment. You appreciate learning from your colleagues and letting them learn from you. Your great interpersonal and communication skills allow effortless collaboration across the organization. Minimum requirements: • Deep analog circuit design expertise, including op-amp topologies, precision current sources, filtering, and low-noise design techniques. • Proven experience designing power supplies, including buck converters, switching regulators, and low-dropout (LDO) linear regulators. • Expert-level proficiency in Altium Designer, including schematic capture, component library management, and design-rule-driven workflows. • Strong PCB layout skills with emphasis on signal integrity, power integrity, and mixed-signal (analog/digital) partitioning. • Experience with high-speed digital interfaces, including PCIe routing (differential pairs, impedance control, AC coupling) and LVDS signaling. • Hands-on experience with board bring-up and debug, including use of oscilloscopes, logic analyzers, and power analyzers to diagnose hardware issues at the component level. • Familiarity with EMC/EMI design practices, including pre-compliance testing and layout techniques for emissions and susceptibility mitigation, is a plus.
