Job Description

About Xanadu:

Xanadus mission is to build quantum computers that are useful and available to people everywhere.

At Xanadu we are learners innovators researchers collaborators and problem solvers. We are creating something that has never been built before. 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 and precision assembly to advance the packaging and performance of our transition edge sensors (TES). As a member of the Low Temperature Devices Team your primary responsibility will be the development of precision cryogenic optical interfaces for photon-number-resolving TES detectors enabling robust low-loss coupling across thermal boundaries from room temperature to milli-Kelvin environments.

With your deep technical expertise and experience in photonic and cryogenic system development you will play a critical role in enhancing the performance and scalability of our detector platform. This role requires significant experience with cryogenic systems optical alignment and photonic hardware as well as the ability to work effectively across disciplines in a fast-paced environment.

You will design build and evaluate cryogenic optical coupling solutions including fiber-to-detector alignment fiber-ferrule and fiber-array design thermal anchoring and alignment repeatability. You will take full ownership of this integration from concept through validation and deployment within large-scale detector arrays. Responsibilities include:

  • Independently operate milli-Kelvin cryostats (dilution refrigerators) including cooldowns troubleshooting and maintenance
  • Collaborate with internal and external photonics process engineers process integration engineers packaging engineers and technicians including at Xanadus foundry partners
  • Design and prototype cryogenic optical interfaces for TES detectors including alignment stages thermal anchoring strategies and vacuum feedthrough coupling
  • Work closely with the room-temperature packaging team to co-develop processes and create a well-defined packaging solution
  • Perform cryostat-based iterative testing to validate coupling performance repeatability and stability
  • Challenge the state-of-the-art in key performance metrics associated with cryogenic optical integration

Required qualifications and experience:

  • Extensive hands-on experience operating cryostats (preferably dilution refrigerators) including cooldowns troubleshooting and maintenance
  • Proven track record designing and implementing photonic or optoelectronic packaging in cryogenic environments
  • PhD in Physics Electrical/Mechanical Engineering or a closely related field with at least 2 years of postdoctoral or industry experience
  • Experience with cryogenic-compatible mechanical and optical design including fiber splicing micron scale passive and active alignment techniques thermal anchoring cryogenic material properties and ultra-high vacuum techniques
  • 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 qualifications and experience:

  • Familiarity with TES MKID or SNSPD platforms and their unique cryo-optical integration challenges
  • Experience writing Python code.
  • CAD and simulation experience for thermal/mechanical modeling (e.g. Solidworks COMSOL)
  • Familiarity with non-destructive imaging techniques and metrology methods such as X-ray microscopy
  • Experience with a variety of wire bonding tools and applications
  • Familiarity with analog test equipment (e.g. VNA SMU)
  • Experience with statistical process control and quality management system reporting methods

Our values are important. They are fundamental and lay the foundation for culture at Xanadu. Learn more about our values here.
