Job Description
Job Title:  Principal Scientist II, Optics & Imaging Systems
Requisition ID:  3253
Posting Start Date:  23/09/2026

Position Title: Scientist / Senior Scientist (X-ray & Computational Metrology), X-ray Section, Optics and Imaging System Group

Job Description:

The Group is seeking a highly self-motivated Scientist or Senior Scientist to architect the next generation of high-throughput, high-resolution inspection solutions. You will lead R&D that bridges advanced physics (X-ray/electron/optical) with Artificial Intelligence to solve critical failure-analysis and production QA challenges in the semiconductor, aerospace, and advanced manufacturing sectors.

You will play a leading role in identifying fundamental physical and algorithmic bottlenecks in today’s industrial inspection workflows. Your mission is to explore, propose, and validate novel R&D topics, ultimately translating breakthrough IP into robust production-ready equipment. We are looking for a thinker who can look beyond traditional X-ray CT and re-imagine how we generate, reconstruct, and interpret 3D data at the nano-scale.

Focused areas include, but are not limited to, the following: 

  • Physics & Source Innovation
  • AI-Driven Reconstruction & Image Quality
  • Intelligent Defect Analysis & Decision Intelligence

 

Job Requirements:

  • PhD in Physics, Applied Mathematics, Electrical Engineering, Computer Science, Materials Science, or a closely related field.
  • 4+ years of post-graduate R&D experience (industry or post-doc) in one or more of the following:
    • X-ray generation, optics, or detector physics.
    • Computational imaging / Inverse problems (e.g., CT, MRI, RADAR, Seismic).
    • Applied Machine Learning (Computer Vision, 3D Point Clouds, or Signal Processing).
  • Strong track record of publications and grant applications
  • Innovative, self-driven, adaptable, and proactive team player with a demonstrable ability to work across physics, engineering, and data science disciplines.

The above eligibility criteria are not exhaustive. A*STAR may include additional selection criteria based on its prevailing recruitment policies. These policies may be amended from time to time without notice. We regret that only shortlisted candidates will be notified.
