The 27-year-old will work with Kevin Ballâ€™s development side and the other academy teams, monitoring and analysing player performance data, reports the Evening Chronicle.
â€śI wasnâ€™t looking to leave Carlisle but when Sunderland called and offered me the position I was very flattered,â€ť said Blake, who had been working within the youth setup at Brunton Park.
â€śItâ€™s an interesting job at a good club and I decided to give it a go.
â€śIt was a hard decision because, while there has been a lot of bad press around Carlisle, I do feel they are going in the right direction and trying to do things the right way.
â€śIt is sad to leave but sometimes you have to take these chances.â€ť
