Job summary

Lumina Corp is building a visible-light photonic integrated circuit (PIC) platform and seeks a Photonics Fabrication and Test Engineer who can turn concepts into repeatable, high‑yield fabrication flows.

This hands‑on role covers process development, integration, metrology, and yield, collaborating with design and test teams to close the loop quickly. A PhD and 2+ years in semiconductor/photonics fabrication are preferred.

Qualifications

• PhD in Physics, Engineering or equivalent.
• 2+ years hands-on semiconductor/photonics fabrication experience.
• Expert in EBL, ICP‑RIE, PECVD, Thermal Evap, SEM.
• Experience 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 (lithography, etch, deposition, lift‑off, cleaning, anneals).
• Establish robust process windows, controls, and documentation.
• Drive metrology + feedback loops (profilometry/ellipsometry/SEM/AFM/optical inspection) 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.
