Senior Nucleic Acid Chemist

Do you want to be a part of an interdisciplinary dynamic team who shares the vision of better cancer diagnostics by developing and improving RNA-based technologies?

Today, there is a need for more precise and personalized RNA-based cancer diagnostics. RNA visualization and sequencing are an integrated part of R&D programs in the pharmaceutical industry, cancer centers, institutes and hospitals. Future healthcare will increasingly depend on accurate diagnosis and subsequent personalized treatment the best possible treatment regimens for patients.

Our biotech company, MultiplexDX, aims to significantly 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, quantitative, cost-effective and multiplexed diagnostic test for cancer, which can precisely identify and quantify cancer markers in human tissues and blood.

The position

We are now looking for an experienced Senior Nucleic Acid Chemist to take the lead in the production and R&D of modified oligonucleotides that will be used in our RNA-based diagnostic technologies and applications. In this multifaceted role, you will help to advance our next pipeline of designed diagnostic products, solve technical obstacles and track costs associated with the modified oligonucleotide synthesis, will study patents, read scientific papers, test different concepts in the laboratory and generate new ideas in collaboration with our team of innovative Molecular Biologists.

You will report to the Chief Operating Officer and be based at the headquarters in Bratislava, Slovakia.


  • Lead production team for modified oligonucleotide synthesis (running small to large scale automated DNA/RNA synthesizers), purification and characterization;
  • Development of analytical methods for the characterization, quantification and purity assessment of oligonucleotides;
  • Preparation of fluorescent dye and pre-adenylated conjugates of oligonucleotides;
  • Documentation of experimental work; analysis of data; documenting and presenting results;
  • Preparation of written methods and SOPs;
  • Operation and maintenance of laboratory & analytical equipment;

Modified oligonucleotide synthesis and preparation of RNA/DNA FISH probes, pre-adenylated sequencing adapters, qPCR probes, etc. enables more specific, precise, automated, high-throughput, multiplexed and quantitative RNA visualization and sequencing technologies that are essential for accurate and personalized cancer diagnostic applications. MultiplexDX diagnostic products combine RNA visualization and sequencing to come up with a specific “barcode” of each cancer, which suggests the specific, personalized treatment and medicines to be used, but also how long a therapy should last. In MultiplexDX diagnostic tests, multiplexing stands for cross-testing and verifying the same result from two independent perspectives, visualization and sequencing. This multiplexed platform provides the most precise clinical parameters and patient’s cancer profile, which enables an oncologist to make an evidence-based decision and target treatment quickly, directly and more accurately.
