Senior Engineer for Photonic Module Characterization
Senior Engineer for Photonic Module Characterization
Join to apply for the Senior Engineer for Photonic Module Characterization role at Q.ANT
This role is enabling next generation analysis and characterizations of thin‑film lithium niobate (TFLN) structures, photonic integrated circuits (PICs) and modules operating in the GHz regime. System‑on‑chip measurements and electro‑optical characterizations for photonic‑modules enable the development, integration and verification of essential building blocks for our core products and demos. This role is combined with responsibilities for PIC labs.
Key Responsibilities
- Deliver high‑precision performance data enabling design validation, root cause analysis, and manufacturing yield improvement.
- Shorten design‑to‑validation cycle time through efficient setup automation and streamlined test methodologies.
- Enhance product performance and manufacturability by providing clear, data‑driven recommendations to design and process teams.
Education and Experience
Education: Master’s or PhD in Photonics, Electrical Engineering, Applied Physics, or a related field.
- ≥3 years in photonic device characterization, with ≥2 years in GHz‑regime high‑speed testing.
- Proven track record in setting up and optimizing optical & RF probe stations for PIC measurements.
- Experience mentoring or supervising students or junior engineers in lab environments.
Technical Knowledge
- Thin‑film lithium niobate device physics and applications.
- SEM and microscopy techniques.
- High‑speed optical modulation, detection, and RF signal integrity principles.
- Measurement instrumentation (VNAs, high‑speed oscilloscopes, optical spectrum analyzers, RF probes, tunable lasers).
- Calibration methods for optical and RF systems.
Tools & Processes
- Automation scripting (Python, LabVIEW, MATLAB).
- Data acquisition systems and post‑processing workflows.
- Familiarity with cleanroom processes and device fabrication steps.
Languages
Fluent in English; proficiency in German or another European language is a plus.
Why Us
- Make growing demand in compute and sustainability go hand in hand.
- Work on leading‑edge photonic AI acceleration technologies.
- Collaborative and innovative work environment.
- Own your work from day one and fast‑track your professional growth.
- Work alongside a passionate, international, cross‑functional team of experts.
- Collaborate closely with the company’s founders and core leadership team.
