Some roles at the Irish arm of US fantasy sports and betting company, DraftKings, are at risk of redundancy, the company has said.

The firm is to reduce its global workforce by around 140 as part of a reorganisation focused on achieving efficiencies.

Globally the betting giant employs around 4,000 people.

In its Dublin office over 70 people are employed across a range of business functions, including engineering and data centre operations, according to its website.

However, it has not indicated publicly how many of those jobs are at risk.

"With an increased focus on operational efficiencies, we are constantly evaluating our teams to ensure that they are best positioned to meet our company goals in 2023 and beyond," the company said in a statement.

"We have decided to reorganize some teams which is resulting in the elimination of approximately 140 roles with some in Ireland being placed at risk."

It is understood that the impact of the reorganisation will be across the firm's entire global employee footprint.

None of its offices will be closing and the Dublin office remains operational.

The company has had an Irish office since 2019, when it announced it was locating 30 software engineers here.

The firm recently announced that it was no longer going to offer its daily fantasy sports contests in Ireland, as well as Austria, Germany and Malta.
