## Description

We are seeking a Senior Signal Integrity Engineer – Cryogenic Interconnects to join our dynamic team working with state-of-the-art, unique technology.

The successful candidate will develop accurate 3D EM models for PCB and interconnect structures using tools such as HFSS, simulate multi-layer PCB designs under cryogenic conditions, and define high-speed constraints, SI specifications, and design guidelines across RF, materials, and thermal domains.

Responsibilities:

- Develop accurate 3D EM models for PCB and interconnect structures using tools such as HFSS

- Simulate multi-layer PCB designs under cryogenic conditions

- Define high-speed constraints, SI specifications, and design guidelines across RF, materials, and thermal domains

- Work on next-generation cryogenic interconnect solutions for ultra-high-speed communication

- Collaborate closely with SI, materials, mixed-signal, and system teams to drive end-to-end interconnect performance

- Perform lab characterization and validation using network analyzers and other measurement tools

- Correlate simulation results with hardware measurements to improve modeling accuracy

- Contribute to system-level understanding of interconnect behavior across PCB, package, and system domains

Requirements:

- MS/PhD in Electrical Engineering or equivalent experience

- 5+ years of experience

- Strong experience in signal integrity modeling and simulation (HFSS or similar EM tools)

- Deep understanding of high-frequency / broadband design

- Solid understanding of multi-layer PCB design and signal behavior

- Knowledge of PCB materials and their electrical and physical properties

- Experience with lab measurements (VNA, high-speed characterization)

- Background in cryogenic technologies or strong interest in developing expertise in this area

Nice to Have:

- Experience working on low-loss / ultra-high-speed interconnects

- Background in materials modeling or SI-material correlation

- Experience in extreme environments (cryogenic, thermal, or reliability-driven design)

- Track record of correlating simulation to hardware measurements

- Strong cross-functional experience with PCB, package, and system teams

You will also be eligible for equity and benefits.
