Job Description

Job Description Job Description

Lumina Corp is building a visible-light photonic integrated circuit (PIC) platform, bringing high-performance modulators and related devices from lab to product. We're looking for a Photonics Fabrication and Test Engineer who can turn device concepts into repeatable, high-yield fabrication flows and continuously improve them.

This is a hands-on role spanning process development, integration, metrology, and yield, working closely with design and test to close the loop fast.

What you'll do

  • Develop, own, and improve end-to-end photonics process flows (process integration, recipe development, yield improvement)
  • Run and refine core cleanroom steps (as applicable): lithography (photo/e-beam), etch (RIE/ICP), deposition (PECVD/Thermal Evap), lift-off, cleaning, anneals
  • Establish robust process windows, controls, and documentation
  • Drive metrology + feedback loops (profilometry/ellipsometry/SEM/AFM/optical inspection, etc.) to correlate process to device performance
  • Collaborate across fabrication, design, and characterization to improve performance, repeatability, and manufacturability
  • Run post-fabrication test and characterisation flows to measure design performance.

Requirements

  • PhD in Physics, Engineering, or equivalent.
  • 2+ years hands-on semiconductor/photonics fabrication process experience (industry, lab, or foundry)
  • Expert in EBL, ICP-RIE, PECVD, Thermal Evap, SEM (and other typical metrology tools)
  • Experience working with measurement stages, optical and electrical probe alignment, data management.
  • Strong fundamentals in process engineering: process control, recipe development, documentation discipline
  • Demonstrated ability to troubleshoot complex process issues end-to-end
  • Comfortable working in a fast-moving, flexible environment with high ownership

Benefits

  • Health-care, Vision, Dental Coverage
  • Training & Development
  • Paid Time Off (Vacation, Sick & Public Holidays)
  • Stock Option Plan
