- R&D

ProQR Therapeutics is a biotechnology company listed on NASDAQ with offices in Leiden, the Netherlands and Cambridge, Massachusetts, USA. ProQR is focused on the development of life changing RNA therapies to meet the unmet need of individuals and families with common and rare diseases. A team of 180+ enthusiastic ProQRians from all walks of life and more than 30 different nationalities is up to this challenge. We have the passion and commitment to make a difference in the lives of the communities we serve. Our proprietary Axiomer® RNA editing technology platform enables the editing of specific single nucleotides in RNA using the cells own editing machinery. Axiomer® RNA editing technology harnesses ADAR (Adenosine Deaminase Acting on RNA), which is machinery present in all human cells to repair G-to-A mutations, modulate protein, and enable protective mutation functions. Axiomer could potentially yield a new class of innovative medicines and treat currently untreatable diseases.
Our Axiomer Unit is currently looking for a Principal Scientist Liver (Full-time) to join our team.
Location: Leiden, NL (on-site).
The role:
As a ProQR Principal Scientist Liver you will scientifically steer the liver programs in collaboration with internal and external partners, focused on the development of novel drug candidates for the treatment of chronic liver diseases. You are a strong scientific thinker with significant experience leading the discovery and development of oligonucleotide therapies for liver diseases, and have extensive experience developing and/or evaluating novel nucleic acid-based therapeutics and delivery platforms. As part of the Axiomer Drug Discovery Unit, you will work closely with scientific program directors, the VP Axiomer Science, and the Chief Scientific Officer. In your role, you will support, evaluate, and/or identify scientific development opportunities to enhance project progression and/or platform expansion, with specific application to the needs of the liver portfolio, including nucleic acid-based therapeutics and delivery platforms. You won’t have direct reports, but you will work closely with different project teams with multiple project leads in a matrix organization. In-depth scientific liver disease knowledge and good project and organization skills are a must.
How you will contribute:
- Scientifically contributes to novel scientific projects and creates scientific direction in projects.
- Lead efforts to determine the mechanism of action for drug targets and candidates using state-of-the-art methods and analytical tools.
- Providing support in the definition of target-related biomarkers
- Executing analysis of complex in vivo data, looking at in vitro/ in vivo data correlations, and in vivo predictive modelling
- Oversee the execution of drug candidate and platform development programs, utilizing cutting-edge methods and tools such as omics technologies (RNA-seq, proteomics via mass spectrometry), and computational modeling.
- Collaborate closely with internal teams (R&D, Clinical Operations) and external partners (CROs, academic institutions) to ensure seamless integration and alignment of research efforts, driving innovation and efficiency in drug development.
- Proactively identify complex obstacles to progress by conducting thorough risk assessments.
- Recommend and implement innovative solutions using a diverse set of resources, including advanced data analytics, cross-functional collaboration, and external partnerships; contribute to research projects through creative problem-solving, leveraging cutting-edge technologies and interdisciplinary approaches to drive scientific and operational excellence.
- Develop and determine optimal methods for new assignments by conducting comprehensive literature reviews, pilot studies, and stakeholder consultations; make strategic recommendations on projects based on data-driven insights, feasibility analyses, and alignment with organizational goals.
- Effectively manage a wide variety of tasks and techniques; integrate these responsibilities to deliver high-quality results with maximum efficiency by fostering cross-functional collaboration, maintaining rigorous quality control standards, and continuously improving processes.
- Be a scientific mentor and team player.
- Communicate effectively with colleagues and leadership.
We expect our Principal Scientist Liver to have:
- PhD degree in a scientific discipline with a postgraduate experience of minimum 2 years, followed by at least 8 years of relevant work experience in Pharmaceutical/Biotechnology for liver diseases, or
- MS with 14+ years of experience, or
