About RiviaRivia is a data engine for clinical trial intelligence. It provides data infrastructure and AI-driven workflows for clinical trial teams, enabling biotechs to run studies more efficiently and to demonstrate which patients derive the greatest benefit from new therapies. Biopharma companies are the source of most therapeutic innovation, yet clinical development is frequently slowed by fragmented data and outdated tooling. Rivia delivers a real-time, integrated view across clinical trial data, improving both trial execution and the evaluation of new treatments.
Our goal is for Rivia to become the new standard infrastructure for modern drug development, bringing new therapies to market more successfully at a fraction of the cost.The RoleAs a Senior Backend Engineer, you will lead the design and implementation of scalable backend services and data infrastructure that power our clinical trial data platform. You will own major parts of our backend architecture, from APIs and data models to integration with cloud services and machine learning components, while being comfortable contributing across the stack when needed. You will collaborate closely with product, data, and frontend teams to ship high-quality features iteratively and help shape the future of our platform.To succeed in this role, you should have a passion for iterative product development and possess a strategic, analytical mindset. You should be comfortable navigating the uncertainties of a startup environment, adaptable to shifting priorities, and driven to transform the pharmaceutical industry. Embrace the challenge of building the future of clinical trial technology and help realize Rivia's vision of becoming the definitive unified data infrastructure for clinical trials.Our stackSome technologies we use today: Typescript, React, Java, Python, Spring, Postgres, GPT-4, AWS, Kubernetes.There's no need to be a prior expert in our stack; it's more important that you learn new technologies quickly.Working Model: This role is based on-site in our Zürich officeWhat excites you
