Engineer in Optical Instrumentation for Cryogenic Super-Resolution Microscopy

Position description Category Optics and Optronics Contract Fixed-term contract Job title Engineer in Optical Instrumentation for Cryogenic Super-Resolution Microscopy (cryo-PALM) H/F Socio-professional category Executive Contract duration (months) 36

Job Description
Would you like to design, assemble and optimise optical instruments for microscopy at very low temperatures? Join us as a engineer on a three-year fixed-term contract within the ANR EPIC project. You will develop and improve a cryo-PALM microscope and help establish reliable cryogenic sample transfers between fluorescence and electron microscopy at IBS/IRIG As a engineer, your responsibilities will include:
• Design, assemble, align and optimise the optical systems of the cryo-PALM microscope: excitation and emission paths, photon collection efficiency, spatial sampling and point spread function (PSF) characterisation.
• Implement and test illumination and acquisition strategies for cryo-FIB lamellae: spatially targeted activation/excitation, reduced sample heating and improved localisation precision for fluorescent molecules.
• Improve, test and document vitrified sample transfers between cryo-FIB/SEM, cryo-PALM and cryo-electron microscopy, maintaining cryogenic conditions and preventing contamination or deformation of the lamellae.
• Implement calibration procedures and help integrate the correlative cryo-PALM/cryo-ET workflow with cryo-EM and image processing specialists; support the evaluation of fluorescent proteins within the project. Applicant Profile We seek an engineer specialising in experimental optics or photonics. You hold an engineering degree (diplôme d’ingénieur or equivalent) or a PhD with strong practical experience in optical instrumentation. Hands-on experience designing, assembling, aligning and optimising optical or microscopy setups is essential. Knowledge of biophysics or biological applications is an asset; you will work closely with specialists in biology and cryo-EM. Prior PALM or cryo-EM experience is welcome but is not required. Technical Skills Strong practical skills in experimental optics, photonics and optical instrumentation. Hands-on experience designing, assembling, aligning and optimising optical setups and integrating scientific instruments. Knowledge of fluorescence microscopy, super-resolution imaging, cryogenic instrumentation or biological applications would be an asset. Skills in instrument control, acquisition automation, programming or experimental data processing would be an asset. Interpersonal Skills Independence, scientific rigour and good organisational skills. Initiative, scientific curiosity and the ability to propose solutions to experimental challenges. Ability to work as part of a team and collaborate in a multidisciplinary environment. Good communication skills and the ability to share scientific results. Language Skills Good command of spoken and written scientific English to work in an international environment. Knowledge of French is welcome but is not essential. 🤝 Why join us? ….
