Senior Hardware Engineer

PIXCEL (https://www.pixcel.com) develops novel semiconductor-based photonic modules aimed at sensing and imaging applications.

What you'll do:

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.
