Senior Molecular Biologist ─ Fluorescent In Situ Hybridization


Bratislava, Slovakia

Today, there is a need for more accurate and personalized RNA-based cancer diagnostics. RNA visualization and sequencing are an integrated part of R&D programs in the pharmaceutical industry, and are increasingly used at cancer centers, institutes and hospitals to provide more accurate diagnosis and subsequent personalized treatment regimens for patients.

Our biotech company, MultiplexDX, aims to drastically increase the number of cancer survivors through personalized diagnostics that lead to tailored, effective, and life-saving treatment. We want to bring to market a reliable, accurate, quantitate, cost-effective, and multiplexed diagnostic test for cancer, which can accurately identify and quantify cancer biomarkers in human tissues.

We are looking for an experienced Senior Molecular Biologist ─ Fluorescent In Situ Hybridization (FISH) to take the lead in planning, conducting, and optimizing RNA-based FISH experiments.

In this multifaceted role, you will help advance our next pipeline of designed diagnostic products, solve technical obstacles, test different concepts in the laboratory, read scientific papers, track R&D costs, study patents, and generate new ideas in collaboration with our team of innovative Molecular Biologists.

You will report to the Director of Research & Development and Chief Operating Officer and be based at the headquarters in Bratislava, Slovakia.

MultiplexDX recently received an EIC Accelerator grant, which guarantees two years of funding for this position with the possibility of an extension.


  • Plan, conduct, and optimize RNA-based multiplexed FISH experiments and tissue image analysis using fluorescence microscopy/confocal microscopy;
  • Develop RNA FISH workflows with an emphasis on incorporating automated processes;
  • Participate in designing and testing new RNA FISH probes;
  • Perform routine histopathological examination of tissues, including tissue processing/preparation (e.g., paraffin-embedding, microtome sectioning) and histological staining (e.g., hematoxylin and eosin staining);
  • Operate and maintain laboratory & analytical equipment;
  • Generate new concepts and ideas in collaboration with the team;
  • Test concepts in the laboratory;
  • Document experimental work, analyze data, document and present results;

  • Manage and mentor research associates;
  • Help to set the company’s strategic direction in terms of cancer diagnostics area of interest;
  • Stay abreast of recent developments in RNA FISH and their applications in clinical diagnostics.


  • PhD in Molecular Biology (or related field) with extensive training and practical laboratory experience in RNA FISH and tissue imaging using fluorescence microscopy/confocal microscopy;
  • MSc degree holders will be considered if they can demonstrate significant experience;
  • Experience in routine histopathological examination of tissues is an advantage;
  • 2 years hands-on laboratory experience with RNA library preparation for next-generation sequencing and other molecular biology techniques (qPCR, gel electrophoresis) from academia, biotech or similar industry is an advantage;
  • Ability to work independently as well as part of a multidisciplinary team is essential;
  • Excellent analytical and systematic troubleshooting skills;
  • Strong creative skills and out-of-the-box thinking;
  • Demonstration of goal-oriented, hands-on, and innovative approach to problem solving;
