Optical Engineer- Summer Intern


We are seeking summer interns to join our Hardware Engineering team developing instrumentation for optics-based biosensing. The ideal candidate would be a hands-on Ph.D. student in the field of Applied Optics, Optical Engineering, Optical Physics, or similar, who is planning to graduate within a year or who has just graduated. You will play an important role in expanding the 10x product portfolio by developing and validating novel instrument concepts and prototypes. The project scope is three full months of June-August 2020 and there is an internship-to-hire opportunity for an outstanding individual.


Key Responsibilities


  • Prototyping: assembly, alignment, and validation of optical imaging detector components.
  • Automation: developing data acquisition routines that read various sensors and control mechanical, fluidics, and optical devices.
  • Modelling: using Zemax or Matlab for optical imaging and image processing concept development and validation.


Required Skills and Background 


  • Familiarity with catalog optics, optomechanics, and usual applied optics lab instrumentation.
  • Experience with the alignment of basic optical assemblies: beam expanders, spatial filters, etc.
  • Good understanding of one or more optical detection or analysis techniques.
  • Familiarity with some of the following applications:
    • Microscopy (brightfield, darkfield, epi-fluorescence, confocal).
    • Spectroscopy (absorbance, fluorescence, Raman).
    • High content cell imaging.
    • Flow cytometry or cell sorting.
    • Optofluidic and microfluidic devices.
  • Experience with some of the following materials:
    • Fluorescent dye molecules or fluorescent proteins.
    • Colloidal micro- or nanoparticles.
    • Dye-labeled cells or biomolecules.
    • Quantum dots or polymer dots.
  • Experience with some of the following devices:
    • Solid state, fiber, or diode lasers.
    • High power single-color LEDs.
    • Silicon photodetectors or photon counters.
    • CCD / CMOS area scan or line scan cameras.
    • Fiber-optic assemblies and alignment.
    • TEC elements and controllers.


Desired Skills and Background


  • Familiarity with any popular lens design software: non-sequential analysis, optimization, tolerances.
  • Working knowledge of any modern programming language used for data acquisition and signal processing.
  • Experience with building custom optical setups or heavily modifying commercial optical instruments.


All qualified applicants will receive consideration for employment without regard to race, sex, color, religion, sexual orientation, gender identity, national origin, protected veteran status, or on the basis of disability.
