Senior Wet Etch Engineer

Be the go-to wet etch expert in a fast-growing photonics foundry.

SMART Photonics aims to be the trusted, leading Tier 1 foundry and development partner in integrated photonics. We work closely with our customers to create innovative products that improve people’s lives. To support our growth towards high-volume production, we are expanding our Process Engineering team and are looking for a Senior Wet Etch Engineer.

Your role

Together with your colleagues, you develop, optimize and sustain the fabrication processes behind photonic devices such as lasers, optical amplifiers and photonic integrated circuits. Your goal is to make our processes efficient, cost-effective and stable, so that every wafer meets our customers’ specifications.

As Senior Wet Etch Engineer you report to the Cluster Lead. You will:

• Own the wet etch process: make sure all wet etch processes and tools are released on time, correctly qualified and in line with our safety guidelines.
• Improve continuously: analyze existing processes and control systems (e.g. SPC, Cp/CpK) and turn the findings into higher efficiency, better yield and lower costs.
• Be the technical reference: bring in-depth knowledge of chemical wet etch processes in a wafer fab, support the process experts in the team and step in where needed.
• Coach and grow the team: guide junior colleagues in taking ownership and strengthening their skills.
• Represent your department: contribute technical depth and strategic perspective in management meetings and presentations, and work closely with colleagues from Equipment, Operations, Integration and R&D. Job requirements
