Data Scientist Senior Consultant

ABOUT SQUARCLE / THE TEAM

Squarcle is a growing strategy, operations and digital consultancy dedicated to driving the performance of our clients. We are people orientated and pride ourselves on our people-first culture. Unlike many consultancies, Squarcle is as equally dedicated to delivery as it is to design.

The Technology and Digital department, led by the Head of Digital, is responsible for providing expert technology and digitisation strategy, operational optimisation and analysis advice to clients operating within a fast-moving global environment. The team is made up of subject matter experts that work to a manager to deliver the client and internal Squarcle mandate. Working together but often independently, each team member will be expected to work onsite and remotely with the client, on complex and exciting big data and digital challenges.

Squarcle is committed to equality and diversity, and our aim is to build a diverse, dedicated, and high-performing team of subject matter experts to help our clients achieve supply chain and operational excellence.

The Data Science Senior Consultant reports to a manager and is responsible for the provision of independent expert advice to help identify and solve data science and digital challenges, increase value, and maximise business efficiency and profitability. Using established processes whilst working with the client’s senior leadership and support staff, the consultant will assist in the creation of digital strategies, processes optimisation and identifying technology solutions to meet client needs.
