Qualifications: * Graduate degree in life sciences, medical sciences, computer science or equivalent professional experience. * At least 3 years of professional experience in production-grade life science datasets, including with AI-enabled applications. * Experience working with structured publishing platforms and data tools; comfort with automation concepts * Experience working with and statistically analysing large and complex data sets, including data cleaning and preprocessing. * Excellent problem-solving skills and the ability to work independently. * Excellent communication skills, especially between technical and non-technical teams. Preferred: * Experience working with Generative AI, especially LLMs, including agents, throughout the entire software development lifecycle (SDLC). * Experience creating MCPs and consuming them into Agentic workflows. * Experience in fast-paced, novel product development.
