Senior Hardware Engineer

PIXCEL () develops novel semiconductor-based photonic modules aimed at sensing and imaging applications.

• 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.

You will be part of a multi-disciplinary start-up team, including optical, electrical, mechanical, and software engineers. You will work closely with PIXCOL's silicon photonics development leads. The position is based in Matawan, NJ.

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.

• 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.
