If you’re ready to lead high-speed photonic test operations on a cutting-edge platform, this is the opportunity to put your mark on something that matters.
A deep-tech company at the forefront of photonic AI acceleration is hiring a Senior Characterization Engineer to lead the testing of thin-film lithium niobate (TFLN) photonic integrated circuits operating in the multi-GHz regime. You’ll design and oversee sophisticated test environments, drive data-led design improvements, and mentor the next generation of engineers.
The Role
This is a hands-on leadership role focused on high-precision photonic and electrical measurements. You’ll define and manage test strategies, build out lab infrastructure, and interface directly with design, process, and manufacturing teams to guide product development.
Key Responsibilities
* Lead daily lab operations and ensure high-quality, repeatable testing of PICs and optical modules
* Build and maintain advanced optical and RF test setups (VNAs, probe stations, tunable lasers, etc.)
* Define test procedures, calibration strategies, and data workflows
* Collaborate closely with design and fabrication teams to translate test results into action
* Manage test schedules and align campaigns with R&D and product roadmaps
* Coach and support junior engineers and technicians
What You’ll Need
* Master’s or PhD in Photonics, Electrical Engineering, Physics or similar
* 8+ years in photonic testing, including 3+ years in GHz-regime testing
* Strong knowledge of TFLN device behaviour, RF signal integrity, and high-speed photonics
* Expert-level experience with optical and RF probe stations, calibration, and measurement systems
* Proficiency in Python, LabVIEW, or MATLAB for automation and data analysis
* Experience mentoring others and leading technical lab environments
* Fluent English (German or other European languages a plus)
Why Apply?
* Be part of a core team shaping a revolutionary photonic computing architecture
* Own and scale a high-impact test function from early R&D to product release
* Work on truly cutting-edge applications in AI and high-performance computing
* Join a passionate, fast-growing, international team backed by leading partners
* Competitive salary and long-term growth in a pioneering deep-tech scale-up
