Hydrology Data Scientist

About the Role

Riverkin is a VC-backed Swiss startup looking for a star hydrologist to join the team. Flash floods threaten thousands of people and cause millions in damage each year but trustworthy alerts are not possible to come by. This is a real under-served problem where todays forecasts break down leaving first responders and municipalities exposed.

Tasks

What Youll Do

**
Build the first flash flood ML model**

• Define and build the first version of the flash flood ML model using sensor data we deploy ourselves and public data sources.
• You implement models manage big data sets and monitor performance.
• You work with software engineer(s) to embed models into a scalable piece of software.
• You are the architect and choose the models the sensors and the architecture as we go.

Translate Business and Customer Needs into a Technical Roadmap

• Youll partner directly with the founders to pull detailed needs out of clients and find the sweet spot between those needs and technical feasibility.
• You keep track of new developments in nowcasting and flood forecasting tools and techniques and own an ambitious technical vision.
• You find the balance between scalable and pragmatic solutions serving customers from day 1 while working towards a long term strategy.

Represent the team on all fronts

• Youre comfortable doing a sensor install on a Tuesday and a customer pitch on a Wednesday.
• You are supportive within the team while standing up for what you believe is best for the customer or company strategy.
• You are an opinionated contributor to key strategic decisions in the company.

Create Clarity and Momentum

• Bring structure to ambiguous problems and drive them to execution
• Make decisions and move forward without waiting for perfect information

Requirements

Who You Are

• Youre excited to solve flash flooding at the local scale
• You want to build a company and youre hungry to act like a founder from day one
• You want to have skin in the game
• You enjoy being a hands-on
• Can take messy inputs and turn them into clear technical direction
• Can move fast but with enough structure to avoid future pain
• Care deeply about building something that actually works in the real world
• An excellent communicator with strong written and verbal skills

Technical Requirements

• Strong experience applying ML tools (e.g. LSTM) to hydrological problems (e.g. flooding)
• Experience in bias correction of weather radar
• MSc or PhD in hydrology water resources management atmospheric sciences or equivalent
• Experience working with real-world data systems (gauges GIS satellite imagery etc.)

Nice to Have

• Previous founder or early startup experience

Benefits

Role Details

• Commitment: 100% FTE.
• Compensation: Commensurate with experience equity
• Growth: this is a key early hire with the opportunity to build and lead Riverkins flash-flood modelling function.
• Location: 4 days per week in Zurich office

About Riverkin

We are a well-capitalized startup building real-time sensing and data infrastructure for rivers. Our own field-deployed sensors collect live water-level and sediment data while our platform turns that data into decision-ready insights for customers. We work across two core use cases: hydropower where better sediment data can support flushing asset protection and compliance; and flash-flood risk where local river data can help first responders and municipalities understand what is happening before conditions become critical. We are a small hands-on Swiss startup working across hydrology hardware field engineering software and market development.
