Job Description

About Us:

We are a newly founded startup sponsored by a global leader in transportation networks.

We provide a new and innovative solution to understand transportation networks by using powerful machine learning tools and stunning data visualisations.

Our product is in use in several major cities across the globe, and we are expanding extremely quickly. We want to be the world leader in smart cities solutions. By reconstituting people's itineraries within a transportation network, we allow cities to finally understand how people move. Using complex algorithms, we can even explore the impact of a modification to a transportation network. We want to help cities adapt their networks so than people can move more easily be more connected.

The Role:

You will join an existing team of one person and will be working on a sane codebase (tested, typed, and well designed).

As you become independent on the project, you will gain the freedom and responsibility to make the technology choices that allow the project to grow and respond to change.

When the front-end team is called to grow, you will become its technical leader.

You will be working with a modern set of tools (React, Redux, Redux Sagas, ES6+, D3, CrossFilter, Leaflet, Jest, Enzyme, Yarn, Typescript) to solve challenging problems of a data-intensive performance oriented web application. You will be part of a team passionate about writing great code, with an emphasis on quality using modern software development techniques.

The role will challenge your ability to create stunning data visualisations, and produce industry-level code.

English speakers are welcome, depending on your profile, visa sponsoring is a possibility.
