Job description
Job description At Orakl Oncology, we are accelerating the development of oncology treatments. Today, fewer than 5% of new cancer drugs succeed in clinical trials. Clearly, new methods are needed. We combine cutting-edge biology and AI to build the next generation of insight platforms with the world's largest cohort of patient tumor avatars.
These avatars fuel our AI-powered predictive engine, helping to anticipate clinical trial outcomes, validate therapies, and uncover new drug candidates. Our mission is simple yet ambitious: to bring more effective treatments to patients who need them — and to make drug development smarter, faster, and more personalised.
We collaborate with top hospitals, research institutes, and pharmaceutical companies worldwide. Backed by leading investors, we are a fast-growing, mission-driven startup at the intersection of science and technology. We are looking for a passionate, hands-on Senior Scientist to expand Orakl's biobank to new indications.
Working with significant autonomy and reporting to Gizem Altay, Principal Scientist, you will own the establishment of patient-derived organoids from fresh surgical specimens — starting with NSCLC and extending to additional tumour types — from tissue receipt and dissociation through to stable, well-characterised lines ready for downstream applications.
You will develop and optimise robust culture protocols, ensure reproducibility across donors, and generate the high-quality biological models that power our AI predictive engine and our partnerships with hospitals and pharma. Preferred experience Must have
- PhD in cancer biology, molecular biology, cell biology, biotechnology, or a related field, as well as 5+ years of hands-on experience, including industry or translational settings.
- Proven, hands-on experience establishing NSCLC patient-derived organoids from fresh surgical specimens — including tissue handling, dissociation, embedding, and long-term expansion.
- Strong track record in primary tumour culture, including troubleshooting low take-rates, and donor-to-donor variability and other optimization including: media formulation, matrix selection, passaging strategies, cryopreservation etc.
- Exceptional wet-lab fundamentals: sterile technique, routine culture, assay development, and QC.
- Prior experience in building scientific direction, ownership of QC/characterisation strategy, and decision-making
- Demonstrated ability to independently plan, prioritise, and execute complex experimental pipelines with high quality and reproducibility.
- Strong analytical and quantitative data-interpretation skills, with clear documentation and reporting.
Nice to have
- Direct experience collaborating with hospitals, pathology departments, or surgical teams on biospecimen workflows.
- Experience with drug-response profiling in organoids (dose–response, time-course, combination assays).
- Knowledge of molecular biology techniques and NGS workflows (WES, RNA-seq) for organoid characterisation and tumour-organoid concordance.
- Previous responsibility for managing CROs or academic collaborations.
- Experience mentoring junior scientists or lab technicians, and establishing lab standards. What will you find at Orakl
- Mission: Work in a cutting-edge environment, on the bleeding edge of cancer research.
- Growth opportunities: we’re rapidly expanding the scope of our work and you will be offered multiple opportunities to grow with it!
- Impact: you’re going to be participating in a fast-growing, multi-faceted project with multiple opportunities to shape it according to your interests.
