What is a cryogenic engineer?

A Cryogenic Engineer specializes in the design, development, and maintenance of systems that operate at extremely low temperatures, typically below -150°C (-238°F). They work with liquefied gases like nitrogen, oxygen, and helium for applications in industries such as aerospace, healthcare, and energy. Their responsibilities include designing cryogenic storage systems, ensuring safety compliance, and optimizing performance. Cryogenic Engineers often collaborate with scientists and researchers to advance technology in fields like superconductivity and space exploration.

What are some common challenges faced by cryogenic engineers in their daily work?

Cryogenic Engineers often encounter challenges related to maintaining material integrity and system performance at extremely low temperatures, which require close attention to safety and precise engineering. Troubleshooting equipment failures or leaks is another frequent challenge, demanding quick problem-solving and detailed knowledge of cryogenic processes. Collaboration with other engineers, scientists, and technicians is common, especially during the design, installation, and testing phases of projects. Overcoming these challenges requires continuous learning, attention to detail, and effective communication to ensure operational safety and optimal performance.

What are the key skills and qualifications needed to thrive as a cryogenic engineer, and why are they important?

To thrive as a Cryogenic Engineer, you need a solid background in mechanical or chemical engineering, thermodynamics, and materials science, typically supported by a relevant engineering degree. Familiarity with cryogenic equipment, CAD software, and safety protocols, as well as certifications in industrial safety or pressure systems, is highly valuable. Strong problem-solving, teamwork, and communication skills help you effectively design solutions and collaborate across multidisciplinary teams. These skills are important to ensure the safe, efficient, and innovative development and maintenance of cryogenic systems in industries such as aerospace, energy, and medical technology.

Job description

We are now looking for a Senior Signal Integrity Engineer - Cryogenic Interconnects! NVIDIA has continuously reinvented itself over two decades. Our invention of the GPU in 1999 sparked the growth of the PC gaming market, redefined modern computer graphics, and revolutionized parallel computing. More recently, GPU deep learning ignited modern AI - the next era of computing. NVIDIA is a "learning machine" that constantly evolves by adapting to new opportunities that are hard to solve, that only we can tackle, and that matter to the world. This is our life's work, to amplify human imagination and intelligence.

This is a dynamic team working with state-of-the-art, unique technology. If you are someone that loves a challenge, come join this diverse team and help move the needle.

What you'll be doing:

  • 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

What we need to see:

  • 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

Ways to stand out from the crowd:

  • 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

Your base salary will be determined based on your location, experience, and the pay of employees in similar positions. The base salary range is 168,000 USD - 264,500 USD.

You will also be eligible for equity and benefits.

Applications for this job will be accepted at least until August 2, 2026.

This posting is for an existing vacancy.
