Senior Research Scientist

The Senior Research Scientist provides technical leadership for semiconductor radiation detector technology used in ORTEC gamma-ray spectroscopy and radiation measurement products, with primary emphasis on High Purity Germanium (HPGe) detectors. This role is responsible for detector science, semiconductor process development, performance optimization, and the long-term technology direction of detector products from research through manufacturable implementation.

Working closely with engineering, manufacturing, quality, product management, customers, suppliers, universities, and national laboratories, the Senior Research Scientist helps advance detector performance, expand technical capability, and strengthen ORTEC’s long-term product differentiation.

Key Responsibilities

Lead experimental programs focused on detector materials evaluation, device optimization, fabrication process improvement, and advanced detector concepts. Develop and enhance semiconductor fabrication methods used in detector manufacturing. Partner with manufacturing teams to improve detector yield, repeatability, reliability, throughput, process control, and final performance testing.

Collaborate with electronics, mechanical, cryogenic, software, systems, manufacturing, and quality teams to optimize complete detector systems. Evaluate emerging detector materials, detector architectures, external research opportunities, and strategic partnerships aligned with ORTEC’s product strategy. Provide technical leadership for detector science, semiconductor process development, and performance optimization initiatives.

Represent ORTEC in technical reviews, high-value customer discussions, scientific conferences, internal leadership reviews, and technology roadmap planning activities.
