• Mentor engineers and support knowledge transfer across teams.

• Provide technical guidance during product development, troubleshooting, and field investigations.

• Lead design reviews and technical decision making.

Required Qualifications

• Bachelor’s, Master’s, or PhD in Electrical Engineering, Opto-Electronics or Physics (or equivalent experience)

• 15+ years of experience in hands-on development of precision instrumentation, photonics, or scientific detection systems.

• Strong background in low-noise analog Amplifier circuit design and schematic capture

• Deep understanding of photodetectors (APDs, photodiodes, photon-counting devices, etc.).

• Experienced development with signal processing for weak signal detection.

• Demonstrated ability to lead complex technical projects,

• Demonstrated use of rapid development methods to enable quick cycles of learning

Preferred Qualifications

• Understanding of the semiconductor fabrication process and chemical usage desirable.

• Experience with optical system design or close collaboration with optical engineers.

• Knowledge of scattering physics and optical measurement techniques.

• Familiarity with modeling/simulation tools (SPICE, MATLAB, Zemax, etc.).

• Prior experience serving as a subject matter expert or technical lead.

• Background in scientific or analytical instrumentation.

Work Environment & Physical Requirements

• This is an “in-office” position 80-100% of the time.  The remainder of the time you may work from home.  These percentages are targets with the actual schedule to be determined in conjunction with the Manager's expectations for the position.

• This role primarily operates in an office/lab/manufacturing environment.  Must be able to sit, stand, and use a computer for extended periods of time

• Occasional lifting of up to 20 lbs. independently may be required

• This role involves occasional working in laboratory environments that include exposure to X-rays, radiation, and biological materials. All work is performed following established safety protocols and regulatory guidelines

Compensation & Benefits

• Competitive base salary range: $140,000 - $175,000 depending on experience

  • Our compensation philosophy: we offer competitive pay based on market data, including local, national, and industry benchmarks.  For new hires, offers are generally within the established min- to mid-point of the range for the role, with flexibility to recognize experience, skills, and education.  Our approach ensures fair pay internally while remaining competitive externally and allows room for growth.

• Comprehensive benefits package:

  • Health coverage: medical, dental, vision, fsa, onsite clinic (CO employees), life insurance

  • 401(k) retirement plan with company match

  • Vacation, holiday, and leave policies

  • Tuition reimbursement, Employee recognition programs, Employee assistance programs
