About Phanofi

Phanofi is a photonics startup dedicated to developing energy-efficient, high-speed optical transceivers and interconnect solutions for data centers and high-performance computing. We combine photonics and electronics to create faster, greener, and more scalable data communication technologies.

Job Overview

As Interconnect Hardware Design Engineer at Phanofi, you will play a pivotal role in developing innovative interconnect hardware that forms the backbone of next-generation data centers and advanced electronics. This position offers the opportunity to lead the design and integration of optoelectronic components, mixed signal electronics, and high-speed PCBs for transceiver solutions within a multidisciplinary team environment.

Key Responsibilities

  • Lead the design and development of high-speed PCB and packaging solutions for advanced interconnect products.

  • Take ownership of transceiver and interconnect hardware designs, including thermal, EMC/EMI, and system performance considerations.

  • Collaborate closely with cross-functional teams to manage complex projects and integrate multiple system components.

  • Support system-level testing, characterization, and validation, focusing on high data rate performance and reliability.

  • Communicate technical concepts and project status effectively across stakeholders and report progress regularly.

Required Qualifications

  • PhD degree or MSc. degree or equivalent in photonics engineering, electrical engineering, or a related technical field.

  • 2+ years of experience in electronic circuit and PCB design, preferably for high-speed interconnects or related hardware.

  • Hands-on experience with microcontrollers, packaging techniques, and hardware validation.

  • Demonstrated skills in managing projects and driving hardware design from concept to production.

  • Proficiency in at least one programming or hardware description language (e.g., Python, C, VHDL, Verilog).

  • Strong oral and written English communication skills.

Preferred Qualifications

  • Expertise in thermal management techniques for high-power density systems.

  • Basic or advanced knowledge of optoelectronic component integration.

  • Familiarity with high data rate system characterization and radio frequency (RF) testing.

  • Understanding of electromagnetic compatibility (EMC) and electromagnetic interference (EMI) design and troubleshooting.
