Role Overview

We are looking for a Process Engineer to develop and industrialize semiconductor fabrication processes, bridging Advanced R&D and Production.

This hands-on role focuses on dry etching (ICP-RIE), PECVD and metal evaporation. Working closely with R&D and cleanroom operators, you will improve device performance, process reproducibility, yield and throughput.

Key Responsibilities

1. Equipment Validation and Recipe Transfer

• Define and run acceptance tests with the maintenance engineer.
• Transfer and optimize recipes on new equipment.
• Establish maintenance, cleaning and conditioning procedures.
• Validate wafer-to-wafer and day-to-day reproducibility through extended runs.

2. Production Capacity and Yield

• Prepare processes for larger wafers, batches and production volumes.
• Improve process robustness, uniformity and yield.
• Establish process monitoring, KPIs and Statistical Process Control (SPC) where relevant.
• Investigate process drifts, yield losses and equipment issues; implement corrective and preventive actions.

3. Device Performance

• Optimize fabrication parameters, particularly dry etching, using structured experimentation and scientific literature.
• Correlate process data with structural, optical and electrical characterization to understand their impact on device performance.

4. R&D-to-Production Transfer

• Turn R&D building blocks into stable, documented manufacturing processes.
• Assess manufacturability, scalability and process risks.
• Contribute to Process Failure Mode and Effects Analysis (PFMEA) and define appropriate controls.

How You Will Grow :

First 3 months: Learn Quandela’s fabrication and characterization flow and contribute to ongoing technical challenges.

Within 6 months: Take ownership of a tool, validate new equipment and support the transition to larger wafers and batches.

Within 1 year: Improve device performance, strengthen statistical process monitoring and support increasing production volumes.

Requirements

Must-Have

• PhD or equivalent research and development experience in semiconductor engineering, materials science, physics, micro/nanotechnology, electrical engineering or a related field.
• Hands-on cleanroom experience in semiconductor fabrication, including dry etching, ideally ICP-RIE.
• Experience with complementary processes such as PECVD, metal evaporation or lithography.
• Understanding of optics and optoelectronics sufficient to connect fabrication parameters with device performance.
• Ability to independently troubleshoot technical problems using experimental data, root-cause analysis and scientific literature.
• Strong communication and documentation skills, with fluent written and spoken English.
• Familiarity with Python for data analysis.

Appreciated Extra Skills

• In-depth knowledge of plasma etching physics and diagnostics, such as actinometry, ion-flux measurements or residual gas analysis.
• Experience with plasma-tool maintenance and process-drift correction.
• Experience with industrialization, R&D-to-production transfer, PFMEA, control plans, SPC or Design of Experiments (DoE).
• Experience with optoelectronic-device design and characterization.
• Knowledge of III-V semiconductors, particularly AlGaAs photonic structures, resonators or VCSEL technologies.

Profile

You combine R&D curiosity and analytical skills with manufacturing rigor. You enjoy hands-on cleanroom work, data analysis and collaborative problem-solving, and can turn exploratory processes into controlled production workflows.

• Competitive salary, flexible based on your experience
• Profit-sharing & company savings plan
• 100% health coverage (Alan)
• 50% transport reimbursement or sustainable mobility bonus
• Meal vouchers (Swile), Gymlib fitness support
• Childcare assistance & referral bonuses (€1,000–€2,000)

• A meaningful role with real ownership, from day one
• A team eager to collaborate and grow with you
• Daily exposure to the entire quantum stack — from high-level APIs to low-level firmware, and everything in between.
  

1. Talent Acquisition interview (30–45 minutes).
2. Hiring Manager interview (45 minutes).
3. Technical interview and team meeting.
4. Two reference checks.
5. Offer.
