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 personalized.

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 and dynamic hands-on scientist to build Orakl's CRISPR and functional genomics capabilities from the ground up.

Reporting directly to the Principal Scientist, Gizem, you'll design and run gene-perturbation and drug screens in our patient-derived tumor organoids, generating the high-quality biological data that powers our AI predictive engine. Preferred Experience MUST HAVE

  • PhD in molecular biology, cancer biology, biotechnology, or related field, ~1–5 years industry experience would be a plus.
  • Proven proficiency with CRISPR gene editing in mammalian systems (ideally in organoids): gRNA design, MOI optimization, KO validation.
  • Experience with both lentiviral-based and electroporation-based is preferred.
  • Hands-on expertise in organoid culture.
  • Knowledge of molecular biology techniques (RT PCR, qPCR/ddPCR, Western Blot, DNA and RNA isolation etc.) and flow cytometry/FACS.
  • Exceptional wet-lab fundamentals: sterile technique, routine culture, molecular biology, cloning, assay development, QC.
  • Demonstrated ability to independently plan, prioritize, and execute complex experimental pipelines with high quality and reproducibility.
  • Strong analytical, quantitative data interpretation, and clear documentation/reporting skills.

NICE TO HAVE

  • Experience with pooled/arrayed CRISPR screens or other functional genomics approaches.
  • Experience with drug-response profiling in organoids (dose–response, time-course, combination assays) and high-throughput screening.
  • Knowledge of programming e.g. Python
  • Previous responsibility for managing CROs or academic collaborations.
  • Experience mentoring junior scientists, lab technicians and/or establishing lab standards.
  • Prior involvement in early-stage drug discovery or cross-functional oncology research. 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.
