Senior Optical R&D Engineer

Pacific Biosciences
Menlo Park, CA 94025
Pacific Biosciences is seeking the best talent for developing light delivery instrumentation that is revolutionizing DNA sequencing.




The Senior Optical R&D Engineer will work within the Instrument R&D team to qualify optical hardware ranging from the optical component levelto lasers, complex optical assemblies, and full optical systems within DNA sequencing instruments. Applying knowledge of optical science, they will define and build optical test apparatuses, execute tests and measurements, collect and analyze data, conduct failure analyses, and present results.




The individual must be a self-starter with exemplary organizational skills. Excellent interpersonal, communication and presentation skills are a must. The applicant must have experience working within a multi-disciplinary team in a fast-paced, technically challenging environment.




Potential Responsibilities:



  • Design, build, and operate optical test apparatuses for




  1. Lasers: Power noise, polarization extinction ratio (PER), wavelength spectra, beam pointing, M2, waist position, etc.

  2. Lenses, windows, and other components: Wavefront error, transmission spectra, birefringence, etc.

  3. Fiber optics: Insertion loss, loss per unit length, PER, mechanical properties, split ratios, etc.




  • Specify and conduct tests of standard and modified optical subsystems operating in sequencing instruments.

  • Design and execute protocols for highly accelerated life tests (HALT) and highly accelerated stress tests (HAST) of optical components and assemblies.

  • Conduct failure analyses, potentially using outside analytical laboratories (SEM, TEM, surface profiling, etc.)

  • Employ advanced analytical and computational skills to interpret and visualize experimental test data.

  • Present findings in highly collaborative intergroup meetings.





All listed tasks and responsibilities are deemed as essential functions to this position; however, business conditions may require reasonable accommodations for additional tasks and responsibilities. 




Qualifications:



  • B.S., M.S. or Ph.D. in physics, optical engineering, mechanical engineering, or equivalent.

  • Knowledge of optical science should be demonstrated in some of the following areas: physics of lasing; guided light and modes of propagation; free space beam propagation and diffraction limits; design of beam shaping optics; fiber coupling; polarization and birefringence; interference; optical damage mechanisms.

  • Digital signal processing and related mathematics: noise, aliasing, digital and analog filtering techniques, Fourier transforms, autocorrelation.

  • Basic statistics.

  • Design of experiments.

  • Coding skills (Matlab, Python or others) including control of instrumentation, data acquisition, data analysis, and data visualization.

  • Familiarity with SolidWorks.





The candidate should have experience with many of the following:



  • Design, construction, and control of optical bench layouts including optical components, optomechanics, cameras, photodiodes, electronic amplifiers and filters, and computer control and data acquisition systems.

  • Handling and alignment of delicate, high precision optics.

  • Design, construction, and operation of beam steering systems.

  • Detailed experimental characterization of lasers including power noise, longitudinal mode spectra, and PER.

  • Laser free space beam metrology (waist and M2)

  • Camera sensor characterization and calibration (noise, gain, dark field calibration, flat field calibration).

  • Athermal lens designs.

  • Design and execution of HAST/HALT.

  • Computer control and data acquisition from commercial metrology equipment such as interferometers, spectrometers, polarimeters, etc.







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