Dublin-born O’Dea won 20 caps for the Republic of Ireland having played international youth football in the same sides as Sheehan, who is also 38.
O’Dea began his coaching career at Motherwell before returning to Celtic in 2019.
He was initially under-18s boss before stepping up to take charge of Celtic B in 2021, and became player pathway manager in 2024.
Swansea also confirmed that Fotheringham will leave the club to pursue new opportunities, having served as first-team coach alongside Stearman towards the end of the season.
“We want to thank Mark for the role he played towards the end of last season, he was excellent for us,” added Sheehan.
“We had a conversation and we part ways on very good terms, we wish him all the very best for the future.”
