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
• Superannuation - 15%
• Training & Development
• Paid Time Off (Vacation, Sick & Public Holidays)
• Stock Option Plan

Lumina Corp is an equal opportunity employer. All applicants will be considered for employment without attention to race, color, religion, sex, sexual orientation, gender identity, national origin, veteran or disability status.
