Analog Transceiver Design Engineer (Optical Compute Interconnect)

Location: On-site in Aachen, Germany

Company

hirify.global develops graphene photonic solutions that connect chips through high-throughput, low-delay, energy-efficient computing networks.

What you will do

• Design and simulate high-speed analog building blocks, including transmit drivers, TIAs, limiting amplifiers, CTLEs, bias circuits, and other transmitter and receiver functions.
• Run AC, transient, noise, jitter, linearity, PVT, Monte Carlo, and post-layout simulations to optimize circuit performance.
• Co-design electrical interfaces with photonics and packaging engineers while accounting for device and interconnect parasitics.
• Support silicon bring-up, laboratory characterization, debugging, and correlation between simulations and measured silicon.
• Work with system architects and senior designers to implement analog IP for OCI Generation 1 and Generation 2 performance targets.

Requirements

• Bachelor’s, Master’s, or Ph.D. in Electrical Engineering or a related discipline.
• 4–5 years of industry experience in analog IC design, or equivalent demonstrated impact.
• Strong knowledge of CMOS analog circuit design, including gain, bandwidth, noise, linearity, feedback, stability, signal integrity, parasitics, and circuit optimization.
• Experience designing high-speed analog blocks such as transmit drivers, TIAs, CTLEs, limiting amplifiers, or SerDes front ends.
• Experience with Cadence Virtuoso/Spectre, MATLAB and/or Python, RF and high-frequency tools such as Keysight ADS or Ansys HFSS, post-layout verification tools, oscilloscopes, VNAs, and BER testers.
• Ability to collaborate across analog, photonics, packaging, layout, and system teams.
