Senior Backend (Full-stack) Engineer

ppRivia is a technology company building a data engine that powers the future of clinical trial intelligence. Rivia was founded on the belief that new drugs can be brought to market more successfully with a fraction of today's capital. /p pBiotechs are the source of most therapeutic innovation, yet clinical development is constantly constrained by fragmented data and outdated tooling. Rivia unifies clinical trial data at scale through a core engine built as a reusable intelligence layer, comprising hundreds of configurations and trial-specific logic, independent of source structure. This vertical stack of data engine, workflows, and agents creates a distinct advantage in how trials are operated. /p pOver the past two years, European and US based biotechs running global clinical trials on Rivia have demonstrated measurable impact, from earlier understanding of therapeutic potential to significantly more efficient trial execution. In March 2026, Rivia raised its $15M Series A led by Earlybird Venture Capital. /p pRivia's ambition is to become the standard infrastructure for modern drug development, transforming how trials are executed end-to-end. /p h3bThe Role /b /h3 pAs 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. /p pTo 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.
