About this job

We are seeking a Test Engineer for Photonics Physics Package to support trapped-ion integrated photonics R&D at our Broomfield, CO location.

Our team develops optics and integrated photonics technologies that enable scaling of our trapped-ion quantum computers from our current 98-qubit Helios system to our future Lumos system with hundreds of thousands of qubits. The data, designs, and expertise from our group inform our next-generation systems, from the overall architecture to the tiniest of details. We are looking for more engineers and scientists to join our cross-disciplinary team. 

All applicants for placement in safety-sensitive positions will be required to submit to a pre-employment drug test.

Key Responsibilities:

  • Lead the development, build, and operation of a new quick-turn cryogenic and vacuum test stand for characterizing and validating components and systems for ultra-high vacuum and cryogenic operation  
  • Collaborate closely with engineers and scientists to translate test objectives into effective sample fixtures, test hardware, and experimental setups, drawing on cross-functional expertise throughout design and execution. 
  • Define requirements, configure equipment specifications, and assemble a complete test system for controlling and interfacing with cryo vacuum chambers  
  • Develop and execute test plans to generate reliable test results while maintaining safe operating conditions working with cryogens, ultra-high vacuum, and lasers  
  • Automate hardware, processes, data acquisition, and data analysis 
  • Build test samples, ultra-high vacuum systems, and test & measurement systems to specifications, including troubleshooting issues and failures as needed 
  • Generate detailed documentation of test plans and findings, including details on test instrumentation, processes, and specific sample setup 
  • Analyze and interpret data to provide feedback and recommendations to support iterative development  

YOU MUST HAVE:

  • Bachelor’s degree minimum
  • Minimum 4 years’ experience (advanced degree inclusive) in hardware building, integration, and test in one or more of the following areas: ultrahigh vacuum systems, cryogenic systems, coherent optical systems, integrated photonics systems  
  • Minimum 2 years’ experience (degree inclusive) in python programming or related language 
  • Minimum 3 years’ experience (advanced degree inclusive) with hands-on build and assembly of scientific hardware and systems using hand-tools, fasteners, electrical wiring, etc. 
  • Minimum 1 year experience (advanced degree inclusive) in test automation using programming and/or control systems 
  • Due to Contractual requirements, must be a U.S. Person defined as, U.S. citizen permanent resident or green card holder, workers granted asylum or refugee status
  • Due to national security requirements imposed by the U.S. Government, candidates for this position must not be a People's Republic of China national or Russian national unless the candidate is also a U.S. citizen.

WE VALUE:

  • Master’s degree in instrumentation, in mechanical engineering, engineering physics, electrical engineering, optical engineering, engineering, physics, or physical science 
  • Broad understanding of fundamental optical, mechanical, thermal, and/or cryogenic principles and practices, and experience applying this knowledge in detail to engineering or scientific projects  
  • Experience with test & measurement equipment, such as power supplies, function generators, electronic loads, multimeters, network analyzers, spectrum analyzers, rf signal generators  
  • Experience in scripting tests and automation using Python or similar programming language 
  • Experience in four or more of the following areas:  
    • ultra-high vacuum principles and equipment  
    • cryogenic principles and equipment  
    • mechanical design and analysis tools, including 3D CAD systems such as Onshape and finite element analysis (FEA)  
    • handling chemicals and choosing adhesives
    • using standard laboratory equipment such as microscopes, ovens, fume hoods  
    • free-space optics, fiber optics, integrated photonics, and/or lasers 
    • basic laboratory electronics, such as PCB design, soldering, assembling electrical connectors and cables  
    • Experience working in a laboratory, production, or cleanroom environment with cleanliness and ESD awareness  
    • Ability to read and follow simple electrical and mechanical schematics and assembly documentation  
    • Experience working in a team and collaborating across disciplines 
    • Deep curiosity and interest in learning new things
