About Rivia
Rivia 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.
Biotechs 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the source of most therapeutic innovation, yet clinical development is constantly constrained by fragmented data and outdated tooling.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.
Over 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.
Rivia’s ambition is to become the standard infrastructure for modern drug development, transforming how trials are executed end-to-end.
The Role
As a Senior Frontend Engineer, you will lead the design and implementation of user‑facing product experiences that make complex clinical trial data intuitive, actionable, and delightful. You will own major parts of our web application, from frontend architecture and UX to integration with backend services, while remaining comfortable contributing across the stack when needed. You will collaborate closely with product, design, and data 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 stack
Some technologies we use today: Typescript & React (must-haves for this role), 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.
