Job Description

We’re looking to add an experienced Data Scientist to our Data Science team. This new team member will be instrumental in leading and developing data science solutions from the idea to maturity as we continue to make the retail world a better, more sustainable place.


At Nextail, we empower retailers to create better experiences while using fewer of the world's resources. Nextail’s cloud-based platform uses artificial intelligence, prescriptive analytics, and optimization to deliver agile merchandising decisions. To date, we’re backed by more than $12M in funding from leading venture capital investors and are working with global retailers like Versace, River Island, and Pepe Jeans.



Data Science at Nextail

The DS Team is part of the Product Team, our goal is to multiply the impact of our product on the business. Data Science Techniques, AI, ML, Optimisation, Simulation, Visualization, are the tools we always have at hand when we face a problem, but we will never use them in vain. We work together with Product Managers, Developers, Data Engineers and Business Experts to solve the end to end problem.

We are business focused, we get into the skin of our customers, we learn to talk their language, we feel their pain and their joy.

We believe in Data Ops, and Agile Data Science methodologies, in adding value fast, keeping things simple, and iterating to improve while the effort is worth it. Life is short, our time is gold, we automate, we prioritize, we ensure focus, we carefully choose our objectives to be sure to achieve them.

Our job is not finished when the model and the end to end solution is in production, or after the change management and operational details are closed, not even when we have strong evidence that the solution is solving the user problem and she is satisfied, because after that we continue monitoring our models.

We are scientists, empiricists, we measure the impact in the business, we progress with small steps, one at a time validating hypotheses at the lowest cost.

We are humble, we never know enough, we embrace uncertainty, we are all the time learning from the wise and the data.

We listen carefully to the business experts, and to our DS pairs and make sure we understand each other, we validate every assumption and hypothesis both with them and with the data, we are always thirsty for feedback and validation.

The discussion between pairs, working together, challenging each other, is the fastest way to solve a problem and to grow as a Data Scientist. We have a culture of sharing, transparency, of meritocracy, of caring and trusting each other.

  • International environment: We operate across the globe, with recent operations reaching from Europe all the way to Australia, and our team alone consists of professionals of more than 15 different nationalities. While many of us are multilingual, our working language is English.

Professionally speaking, are you ready to work alongside tech geniuses, data science magicians, and fashionistas?
