Staff Data Scientist at Bolt (Tallinn, Estonia)

Bolt is one of the fastest growing startups in the world with over 30M happy customers in 30+ countries, from Europe to Mexico to Africa. We’re building the future of transport – one platform that connects you with cars, motorcycles, scooter sharing, and anything else you need to move around in your city. Fast, convenient and affordable for everyone, as transport should be.

Bolt engineering teams are working on unique product challenges: complex algorithms for demand prediction, optimal real-time pricing, routing, fraud detection, distributed systems and much more. Volumes are growing at a steady pace.

This is once in a lifetime opportunity in a massively disrupting urban transportation area. While company is well-backed by strong investors and top talent, it’s small enough for every individual to have a big impact on its future and as well benefit from sky-rocketing equity package!
