Job summary

Lumina Corp is building a visible-light photonic integrated circuit platform and seeks a Photonics Fabrication and Test Engineer to turn concepts into repeatable, high-yield fabrication flows. The role spans process development, integration, metrology, yield, and close collaboration with design and test teams.

You will own core cleanroom steps, drive metrology loops, and push for manufacturability with hands-on lab work and data-driven iteration.

Qualifications

• PhD in Physics, Engineering, or equivalent.
• 2+ years hands-on semiconductor/photonics fabrication process experience.
• Expert in EBL, ICP-RIE, PECVD, Thermal Evap, SEM
• 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

Responsibilities

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