* Metrology plans: Assess, generate, and validate testing plans, ensuring consistent design-for-testability practices.
* Scaling Test Operations: Communicate with tool vendors to assess new solutions for scaling test operations and infrastructure.
* Training: Provide training to test operators and engineers on developed testing procedures and equipment.
Requirements
* Education: MSc, MEng, or PhD in photonics, electrical engineering or a related field.
* Experience: Minimum of 3+ years of hands-on experience in optical testing of passive and active integrated photonics components, gained in a leading university lab or in the industry.
* Technical Skills: Proven experience with automated electronic DC and RF testing equipment (VNA, BER testers, high speed oscilloscope), Wafer-level and/or chip level testing, microwave theory and design, remote instrument control and automation with Python.
* Mindset:Results-oriented experimentalist, dedicated to applying and expanding expertise in optical and electro-optical testing.Pragmatic problem-solver, adaptable to dynamic environments and shifting priorities, with a focus on timely delivery.
* Work Style: Collaborative, transparent team player, and an independent self-starter capable of achieving both individual and group objectives.
* Communication: Excellent communication and reporting skills.
* Language: Working proficiency in English.
It's a plus if you have:
* Experience with DC & RF fixtures
* Electronics experience
* Experience with packaging of photonic or electronic circuits.
* Digital Signal Processing & Modulation Formats
* Code versioning
* Experience with working in a clean-room environment and proper handling of sensitive materials.
Benefits
* A flexible and dynamic start-up work environment.
* Be a member of an international, diverse, customer-focused and highly motivated team.
* Personal responsibility in your job and the chance to grow with us
* Our passion to bring PICs to everyday life.
We look forward to receiving your full application, including 1) your CV, 2) a statement of interest (relating the position to your skills), and 3) grade or work certificates. Incomplete applications may not be considered.
