• Fifteen (15) years of relevant experience
• Deep understanding of photonic detector devices and associated electronics
• Strong analytical, experimental, and problem-solving skills
• Ability to independently evaluate and guide advanced photonics technology directions
• Strong communication, collaboration, and mentoring capability

Preferred Qualifications:

• PhD in a relevant technical discipline
• Experience with photon counting and TCSPC (time-correlated single photon counting)
• Broad knowledge of modern photonics and optical sensing technologies
• Demonstrated success in maturing complex technologies into commercially viable products
• Experience working in multidisciplinary industrial research environments
• Strong innovation track record (publications, patents, or advanced R&D contributions)
• Proven leadership and project execution experience

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.
