Job Summary
At Xanadu we are learners innovators researchers collaborators and problem solvers. We are creating something that has never been built before. What we are doing is extremely hard the classic moon shot. Few people in their life will be able to be a part of something like this where if we are successful the technologies we develop will solve some of the worlds most challenging problems and literally change the world. And that is something to be excited about!
Your role and responsibilities:
In this role you will contribute your expertise in optics and photonics cryogenics to advance the performance of our Superconducting Nanowire Single Photon Detectors (SNSPDs). As a member of the Low Temperature Devices Team your primary responsibility will be the development of record breaking single photon detectors with ultrahigh system detection efficiency short reset time and compact deployment.
With your deep technical expertise and experience in SNSPD system development you will play a critical role in designing and enhancing the performance and scalability of our SNSPD platform. This role requires significant experience with SNSPDs (both in design and characterization) cryogenic systems and photonic hardware as well as the ability to work effectively across disciplines in a fast-paced environment.
You will design assemble and evaluate SNSPDs. You will take full ownership of their development from concept through validation and deployment within large-scale detector arrays. Responsibilities include:
- Challenge the state-of-the-art in key SNSPD performance metrics relevant to Xanadus Architecture
- Independently operate cryogenic systems (e.g. He-4 evaporator based dilution refrigerators) including cooldowns troubleshooting and maintenance
- Collaborate with internal and external process integration engineers packaging engineers and technicians including at Xanadus foundry partners
- Development of novel high-bandwidth low latency RF electronics readout systems
- Perform cryostat-based iterative testing to validate coupling performance repeatability and stability
Required qualifications and experience:
- PhD in Physics Electrical/Mechanical Engineering or a closely related field with at least 2 years of postdoctoral or industry experience
- Proven track record designing improving and characterizing SNSPDs
- Experience with high-bandwidth RF readout electronics
- Extensive hands-on experience operating cryostats including cooldowns troubleshooting and maintenance
- Self-motivated comfortable working both independently and collaboratively with people of all disciplines on complex projects in a fast-paced environment
- Detail-oriented with positive attitude towards work
- Excellent interpersonal and written communication skills
Preferred knowledge and experience:
- Experience writing Python code
- Experience operating dilution refrigerators (DRs) and adiabatic demagnetization refrigerators (ADRs)
- CAD and simulation experience for thermal/mechanical modeling (e.g. Solidworks COMSOL)
- Experience with fibreoptical coupling to superconducting devices
- Familiarity with analog test equipment (e.g. VNA SMU)
- Experience with statistical process control and quality management system reporting methods
