Optical Engineer IV - Scientific Instrumentation (Madison, WI)

  • Location: Madison, Wisconsin
  • Type: Direct Hire
  • Job #3211

Do you have an advanced degree in Optical Engineering and experience working with Bioanalytical products? Have a passion for new product development and want to grow in your career with an innovative and well-known Biotech company? This could be the role you're looking for!

What You'll Do:
Within this role you'll be able to work with a team of engineers and scientists in the US and South Korea with diverse backgrounds and experiences. Projects have included the development of chemistries and instruments designed for a wide range of scientific disciplines and an ability to constantly be involved in new endeavors, evaluating new technologies, and pursuing new approaches to develop the next generation of instrumentation.

In this senior role, you'll be able to use your deep knowledge of physics/engineering to define the optical characteristics of the analytical and detection instrumentation under development, and support the vitality of existing products. The catalog of luminescence-based biological assays typically requires low-light detection that can utilize a wide variety of detection modalities depending on the instrument. The fluorescence-based assays may also require the development of LED or laser-based excitation and single or multiplexed signals for detection.

You'll be part of the team to develop cutting edge integrated systems for biological sample analysis. Boasting both assay and instrumentation development, the company offers the unique opportunity to create integrated systems that bring industry leading performance to the scientific community. Acting as an expert in the design, development, and testing of optical systems for high performance bioanalytical instrumentation, you can be part of an active team bringing innovation to life at a company with a commitment to mindfulness and continued personal and professional growth.


What You'll Bring:

1. Act as a Key Contributor on cross-functional engineering teams to achieve project deliverables. Collaborate with scientists, product management, industrial designers, and others to understand user needs and address those needs in designs.

2. Design, develop, build, and test optical systems used in complex bioanalytical instruments. Illumination sources may include LEDs, lasers, solid state lasers, and conventional lamps. Detectors may include solid-state devices, photomultipliers, and cameras. Systems will include both imaging and non-imaging optics. Spectral regimes will typically span near-UV, visible, and near-IR (200nm to 1200nm).

3. Design and/or specify optical components such as lens, imagers, reflectors, filters, gratings, and detectors, both off-the-shelf and custom. Interface with vendors for optical components, both standard and custom.

4. Analyze and optimize system performance considering, for example, optical and mechanical tolerances, thermal issues, and detector signal-to-noise.

5. Collaborate closely with mechanical and electrical engineers.

6. Perform hands-on work with optical components and systems. Personally perform construction and test of optical prototypes, or supervise technicians doing this work.

7. Where appropriate, apply software simulation tools for optical analysis and optimization.

8. Use current best-practice tools, design methods, and production approaches. Remain current in technology through self-directed reading, training, trade shows, and networking.

9. Plan and develop optical test procedures in conjunction with engineering and production to verify quality requirement guidelines. Specify and design optical alignment and test equipment for both development and production.

10. Use analytical and troubleshooting skills to address instrumentation systems issues. Conduct root cause failure analysis to improve instrument performance and reliability. Perform detailed technical analyses and create test and analysis reports.

11. Provide clear organized documentation to be used by other engineers, production, suppliers, consultants, and regulatory agencies. Prepare and present work at design reviews.

12. Understand and comply with ethical, legal, and regulatory requirements applicable to our business.


1. PhD degree and 4 years of experience is preferred. To be successful in this role, experience should be in developing optical systems and products. It is desirable that the advanced degree be in optics.

2. Expertise in specifying, modeling, analyzing and optimizing optical components and systems.

3. Expertise in measurement and test of optical components and systems.

4. High level of proficiency with one or more optical design software tools such as LightTools, CodeV, Zemax, ASAP, or Trace Pro.

5. Excellent conceptual, analytical and problem solving abilities.

1. Experience with both imaging and non-imaging optics is highly desirable.

2. Experience and skill in electronics is desirable, particularly as related to optical sensors and detectors.

3. Experience with Matlab, Rhino, SolidWorks and similar modelling software is desirable.

4. Experience and skill in mechanical engineering, particularly as related to mounting and alignment of optical components, is desirable.

5. Experience with LEDs and fluorescence systems is highly desirable.

6. Experience in development of analytical instrumentation for biological/chemical applications and/or medical devices in a regulated environment (e.g. ISO-13485 or FDA QMS)..
