Senior Data Scientist

Data Science at Sage means giving businesses of all sizes the technology to better manage everything from money to people. As a Senior Data Scientist here, you'll be part of a global market leader but with a very local heart. Led by Glassdoor's top scoring UK CEO during the Covid-19 crisis, we're a FTSE 100 tech company with over 13,000 colleagues globally and we continually give back to our local communities.
Join us here in Dublin and you'll be working alongside a team of local tech specialists on the fantastic AutoEntry, one of the fastest growing automation software businesses on the market, which we acquired last year. It basically eliminates the pain point of data entry for accountants, saving huge amounts of time and effort and is now servicing over 150,000 businesses across the UK, US, Canada and Australia.
Its modern tech stack uses CI/CD; automated tests; internal package management; push-button deployments to all environments; separate staging environments, automatically provisioned per branch; PR and code review for all changes. In short, it is a pretty awesome piece of kit.
