At **Genestack** we are tackling the underlying computational and scientific challenges of bioinformatics in order to provide researchers with software tools that will streamline the discovery process and drive forward precision medicine, drug development, and bioinformatics research. We're looking for a **Senior Scientific Data Curator/Analyst** with proven experience driving biomedical data curation and harmonisation from scoping through delivery. This is a high\-ownership role ideal for someone who thrives in complex scientific domains and enjoys cross\-functional collaboration. This role combines **deep domain expertise (**biomedical terminology, structured data, and ontologies**)** with **project leadership** — from scoping and standards design to delivery, QA, and stakeholder coordination. **In this role, you will:** * Lead curation workstreams across client projects and internal initiatives. * Extract, structure, and normalize data from scientific sources (literature, protocols, repositories). * Design annotation guidelines and review AI\-assisted outputs. * Own ontology and vocabulary development: mapping, gap resolution, governance. * Build and maintain schemas, traceability logic, and acceptance criteria. * Collaborate across data, product, and engineering teams to scale data harmonisation workflows. * Contribute to pre\-sales, estimation, and delivery planning in professional services contexts. **We would like you to have:** * Degree in Biomedical Sciences, Bioinformatics, or related field (MSc/PhD preferred). * 5\+ years experience in scientific data curation, metadata design, or ontology management. * Deep familiarity with vocabularies/ontologies (e.g., MeSH, NCIt, EFO, ChEBI, Cellosaurus, etc.). * Experience working with unstructured biomedical content and structured repositories. * Strong analytical, documentation, and communication skills. * Comfortable reviewing AI/LLM\-assisted outputs and improving automation strategies. * Experience leading curation in services or consulting settings with delivery responsibility. * Familiarity with scripting languages (e.g., Python, R) for QA or automation. * Excellent communication skills in English. **It would be nice for you to have:** * Prior experience as a Team Lead on data curation projects. * Exposure to **LLM\-based or AI\-assisted curation workflows**. **We offer you:** * international team of professionals; * fully paid sick leaves; * onboarding and domain training for newcomers; * flexible work schedule.
