Early Stage Researcher (PhD candidate) (f/m/d)


The GRINTECH GmbH, a micro-optics company in Jena, employs currently 36 researchers, engineers and technicians. GRINTECH develops and produces micro-optical systems, in many cases using gradient-index microlenses with plane optical surfaces. Preferred applications are in the field of endomicroscopic imaging applications, in conventional miniaturized endoscopy as well as in displacement sensors in the field of optical metrology.

GRINTECH offers within the European Training Network PHAST: Photonics for Healthcare: multiscAle cancer diagnosiS and Therapy (Marie Skłodowska-Curie Innovative Training Network (MSCA-ITN-EID) of the European Commission) the position of an Early Stage Researcher (PhD candidate) (f/m/d) in the context of Multimodal nonlinear imaging for clinical diagnosis in combination with laser ablation for selective tissue removal.


Objectives of the research project “Micro-optical imaging system for multimodal non-linear endospectroscopy”:

  • conception, optical and mechanical design of micro-optical modules for multimodal endomicroscopy and spectroscopy. 

  • optical qualification of the developed micro-optical components by confocal imaging tests, interferometry, Shack-Hartmann sensors

  • assembly technologies of the micro-optical imaging systems and their optical qualification close to or in the final application. 

  • Assisting partners will be Leibniz-IPHT and Medical University Vienna where secondments are planned.



  • We seek an excellent, open-minded and team-spirited PhD candidate with a background in optics/photonics, physics, spectroscopy, imaging, or similar. 

  • Good knowledge of at least two of the following: optical design / optical spectroscopy / microscopy and their application in biomedicine, laser physics, nonlinear optics, electronics, technical programming language (Labview, Python or R), or image analysis. 

  • Fluent communication skills in English, both spoken and written are required. 

  • Candidates will be required to meet the Marie Skłodowska-Curie Early-Stage Researcher eligibility criteria: ( In particular, at the time of appointment candidates must have had less than four years full-time equivalent research experience and must not have already obtained a PhD. Additionally, they must not have resided in Germany for more than 12 months in the three years immediately before the appointment.


We offer:

  • be part of an excellent international research team and benefit from the scientific and complementary training program of the EU-funded Innovative Training Network (ITN) PHAST.

  • highly competitive and attractive salaries according to regulations of Marie Skłodowska-Curie Actions, plus mobility and family allowances as applicable.
