## Job description

## About Rivia

[Rivia](http://rivia.com/) 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the source of most therapeutic innovation, yet clinical development is constantly constrained by fragmented data and outdated tooling.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.

Working Model: This role is based on-site in our Zürich office

What excites you

- Building high‑quality, performant web interfaces that delight end users and make complex data easy to understand.
- Owning features end‑to‑end on the frontend, from initial idea and technical design through implementation, testing, and rollout.
- Collaborating with design and product to refine UX, interaction patterns, and visual polish.
- Occasionally working across the full stack (APIs, data models, cloud services) to unblock frontend work and ship complete product slices.
- Thriving in a fast‑paced startup environment where you have autonomy and make strategic decisions that impact users and the team.
- Leveraging the latest advancements in technology, particularly in AI, to develop great products.

## Responsibilities

- Own the architecture, implementation, and maintenance of core frontend systems and user interfaces for our clinical trial data platform.
- Build robust, accessible, and responsive React/Typescript applications that integrate seamlessly with our backend services and data infrastructure.
- Work across the stack when required (e.g., defining APIs, adjusting backend endpoints, or working with cloud services) to deliver end‑to‑end features.
- Provide technical leadership, helping to design scalable architectures that can support our growth to a multi‑million‑dollar business.
- Address and resolve performance and scalability challenges, both in the frontend and, when needed, in the broader system.
- Level up your teammates by providing mentorship and guidance
- Coordinate closely with sales and customer success teams to ensure technical developments align with customer needs and business objectives

What Excites us

- Extensive experience with Typescript and React
- Previous experience working in a startup environment
- Minimum four years of relevant experience
- A proven track record of taking initiative and leading projects or teams
- Drivers, not passengers
- Excellent problem-solving abilities focused on delivering practical and timely solutions
- Strong technical knowledge and expertise in current and emerging technologies

Hiring Process Our hiring process takes 2-4 weeks over four distinct stages:

- Meet and greet: 30-minute call with the HR team to get to know each other. This is an informal chat.
- Technical Screening: 60-minute interview to delve into high-level technical concepts and your problem-solving approaches.
- Get-to-know a founder: 30-minute discussion with Tiago, our CTO, to introduce you to Rivia and discuss the role in detail.
- Meet the team: 3-4 hours. Join us at our Zürich office for a visit that includes a team lunch and an in-depth technical interview to explore our mutual fit.

## Our Values

At Rivia, we are committed to excellence, continuous learning, and the success of both our customers and our team. If you are driven to exceed targets, eager to shape the future of clinical trials, and passionate about making a meaningful difference in the biotech industry, Rivia is the place for you.

- In it to Win it: Approach every challenge with determination, resilience, and a drive, aiming for the best outcomes and solutions.
- Embrace change: We see change as an opportunity for growth, innovation, and improvement, continuously evolving to stay one step ahead
- Why not?: Asking why not, instead of why, allows us to show our curiosity, allowing us to challenge assumptions and explore new possibilities.
- Find the gap: We are curious and we proactively approach identifying opportunities and solving problems before they arise.
- Collective accountability: We are one team, on one mission and we are committed to shared responsibilities and mutual support, enabling trust and collaboration.
