Job summary

Lumina Corp is building a visible-light photonic integrated circuit platform. We seek a Photonics Fabrication and Test Engineer to turn device concepts into repeatable, high-yield fabrication flows and continuously improve them.

This hands-on role covers process development, integration, metrology, and yield, working closely with design and test to close the loop fast. You will collaborate across teams to optimize performance and manufacturability.

Qualifications

• PhD in Physics, Engineering, or equivalent.
• 2+ years hands-on semiconductor/photonics fabrication experience.
• Expert in photonics fabrication tools and metrology equipment.

Responsibilities

• Develop, own, and improve end-to-end photonics process flows (process integration, recipe development, yield improvement).
• Run and refine core cleanroom steps (lithography, etch, deposition, lift-off, cleaning, anneals).
• Establish robust process windows, controls, and documentation.
• Drive metrology and feedback loops to correlate process to device performance.
• Collaborate across fabrication, design, and characterization to improve performance, repeatability, and manufacturability.
• Run post-fabrication test and characterization flows to measure design performance.

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

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