Senior Scientist – Scientific Services

Rarity Bioscience develops ultrasensitive molecular diagnostics based on our proprietary superRCA® technology, enabling detection of rare mutations that standard methods miss. As our portfolio of pharma and clinical collaborations grows, so does our Scientific Services team - and we are now looking for a Senior Scientist to help lead that work. The role You will lead and contribute to scientific collaboration projects in molecular diagnostics and cancer genomics, from initial dialogue to final report. In this role, you combine scientific leadership with involvement across assay development, performance evaluation, sample testing, data interpretation, and customer dialogue. You bring enough scientific depth to be a trusted discussion partner in cancer genetics, while also being practical enough to plan experiments, assess results, provide guidance to junior colleagues, and help move projects from first dialogue to final report or publication. In addition, the role can be expected to include some hands-on lab work to build familiarity with our assays, workflows, and daily operations, with the level of involvement varying depending on project needs. Key responsibilities: Coordinate and execute service projects involving internal laboratory teams, academic researchers, clinical collaborators, and pharmaceutical partners. Plan, perform, analyze, and report laboratory work across oncology, precision medicine, and mutation detection projects. Analyze, interpret, and report experimental and genomic data in relation to clinical data, somatic mutation profiles, and biomarker analyses. Present results to customers and collaborators, and represent Rarity at scientific conferences and meetings. Act as a scientific and technical subject matter expert in assay development, cancer genomics, and molecular diagnostics. Supervise and mentor junior team members in daily operations and project work. Contribute to scientific publications, technical reports, and conference abstracts. Maintain technical documentation in line with Rarity's QMS and applicable regulatory requirements. You will be part of a small, cross-functional team where the distance between a question and a decision is short. The role is based at our office, soon located at Uppsala Business Park, where all functions will be under one roof. Around 30 people today, growing steadily - the kind of place where you know everyone, and where what you do is visible. Who you are You have deep knowledge of cancer genetics, built through years of working with cancer cohorts, patient data, and somatic mutation profiles. You know what variant assessment means in practice, and you can have a real scientific conversation with a pharma R&D team or a clinical researcher without losing the thread. You can lead a project and bring people along with you. You are structured, logical, and not easily derailed but you can change course when the data tells you to. You want to work on something that matters, in a team where no one is afraid of getting their hands dirty and everyone pulls in the same direction. Qualifications: PhD in Molecular Biology, Cancer Biology, Genetics, Genomics, or a related discipline, with approximately five years of relevant experience in academia, a clinical setting, or industry. Strong MSc candidates with equivalent depth will be considered. Solid expertise in cancer genetics and molecular oncology, including experience working with cancer cohorts and interpreting patient and clinical data. Experience with variant calling, variant assessment, and interpretation of NGS data. Hands-on experience with molecular biology techniques such as qPCR, digital PCR, RCA, NGS-based applications, and/or flow cytometry. Experience in assay development, optimization, and validation. Strong data analysis skills — R or equivalent is an advantage. Excellent written and verbal communication in English. Experience presenting scientific results to customers, collaborators, or at conferences. Experience collaborating with pharmaceutical companies or translational research groups is an advantage. Yes, it is a long list. But then again, we are not just any company - we are a team pushing the boundaries of what mutation detection can do, and we are looking for someone who is genuinely excited about that. How to apply If this sounds like the right next step for you, submit your application no later than mid-October. We review applications on a rolling basis, so do not wait too long.
