You will write code, build integrations, design data pipelines and APIs, and turn ambiguous problems into reliable software used in critical scientific and operational workflows. - Solve problems with users: Work directly with engineers, data scientists, biologists and clinicians from our customers: leading pharma and biotech companies, as well as within Owkin. You will translate ambiguous scientific and operational challenges into concrete software solutions, rapidly prototyping, iterating with users, and delivering results that have measurable impact. - Deploy in the real world: Integrate solutions into large, complex, and regulated organizations. You will work with diverse datasets, existing systems, and multiple stakeholders to ensure that the tools you build are reliable, scalable, and actively used in production. In particular, you will: - Support customer engagements alongside more senior team members, progressively taking on more ownership with external customers to solve high-leverage problems by customizing and extending Owkin’s agentic platform K; - Design, build, and deploy tailored solutions on top of Owkin K, guiding them from conception through final delivery; - Contribute to rapid prototyping and iteration to validate solutions early and frequently; - Balance scope, speed, and quality, adapting plans to ensure successful delivery; - Communicate clearly across technical and non-technical stakeholders to align expectations; - Collaborate with Customer Success Managers, Domain Experts, Product and Engineering teams to guarantee effective delivery, client satisfaction, and sustained adoption of Owkin’s product; - Turn proven patterns into reusable, scalable components, tools, and playbooks; - Share feedback from the field to help shape the roadmap.
